Description

というタービン系Ａ３を考え、それぞれが図１１のような階層構造で構成されているとする。
【００９５】
図１４の部品（車軸）レベルの設備実態摘要表Ｍ６は、図１１の系Ａ３の部品レベルの階層で「車室」、「動翼」、「静翼」、「ノズルボックス」に対応して各作成される。そして、これらの「車軸」、「車室」、「動翼」、「静翼」、「ノズルボックス」の各部品レベルの設備実態摘要表の部品名称と部品評価結果を取り込みまとめると、図１５（Ａ）に示す上位階層の機器（タービン本体）レベルの設備実態摘要表Ｍ７が作成できる。この図１５（Ａ）の設備実態摘要表Ｍ７は、下セルＭ７ａに機器名称「タービン本体」、機器評価結果「異常」が表示され、上セルＭ７ｂに「タービン本体」を構成する部品名称と部品評価結果が表示されている。
【００９６】
同様にして、図１１に示す「タービン本体」と同じ階層に属する「主要弁」、「制御保安装置」、「復水器」、「給水加熱器」についても設備実態摘要表がそれぞれ作成され、作成された各設備実態摘要表の機器名称と機器評価結果が取り込まれまとめられる。この結果、図１５（Ｂ）に示す設備（タービン設備）レベルの設備実態摘要表が作成される。この図１５（Ｂ）に示す設備レベルの設備実態摘要表Ｍ８には、上セルＭ８ｂに「タービン設備」を構成する各機器名称と機器評価結果が表示され、下セルＭ８ａに「タービン設備」の名称と設備評価結果が表示されている。
【００９７】
このように、本実施の形態の処理によって、各部品・部位の図１０に示す損傷実態マトリックス表Ｍ４が求まると、その情報に基づいてシステムで使用している機器体系の階層に従って、図１４乃至図１５（Ｂ）に示すように順番に上位レベルでの設備実態摘要表に集約（上位集約）させることができ、設備としての損傷状況をまとめて簡潔に表現することができる。
【００９８】
この構成により、逆に図１５（Ｂ）の設備レベルの設備実態摘要表Ｍ８から、問題個所の詳細情報を知ることも容易となる。例えば、図１５（Ｂ）のように、タービン設備の設備評価結果が「異常」と表示されたとき、「異常」となっている構成要素に属するタービン本体を選択すると、その内訳である図１５（Ａ）の機器レベルの設備実態摘要表Ｍ７を呼び出し問題個所を絞り込むこと（下位展開）ができる。さらに、図１５（Ａ）において、「異常」と表示されている車軸を選択すると、図１４の設備実態摘要表Ｍ６を呼び出すことができ、さらなる問題個所の絞り込みが可能となる。この上位集約と下位展開の手順はシステムが使用している機器体系に従い自由に行えるため、所望のレベルでの設備実態を参照することが可能である。
【００９９】
次に、図１４の部品レベルの設備実態摘要表Ｍ６から図１０に示す損傷実態マトリックス表Ｍ４の逆変換を行う場合について説明する。
【０１００】
上述のように、図１０の損傷実態マトリックス表Ｍ４から図１４の設備実態摘要表Ｍ６への変換は単にマトリックス表の損傷形態部分のセルを省略することで実施できる。この関係を記憶しておけば、設備実態摘要表Ｍ６から損傷実態マトリックス表Ｍ４へ呼び出し表示することができる。これにより、概括情報を基準としながらも、問題個所と問題点の詳細を再確認することができる。
【０１０１】
次に、本発明の第１実施の形態の別の変形例について図１６及び図１７を参照して説明する。
【０１０２】
本変形例は、プラント内に複数のプラント体系すなわち階層構造を有する場合の例で、各階層構造における「損傷形態マトリックス表」から始まって、「損傷実態マトリックス表」、さらには「設備実態摘要表」の作成処理は、全て図５に示した設備管理システム構成により、これまで述べてきた方式によって処理される。この変形例では、各階層構造内で作成される設備実態摘要表の内のほぼ同一仕様の構成要素についての設備実態摘要表を並列表示することにより、他の階層構造（プラント体系）すなわち他の設備に属するほぼ同一仕様の構成要素についての損傷状況の横並び比較を容易にし、同型構成要素の劣化特性を把握可能とするものである。
【０１０３】
例えば、図１６に示すプラント体系表Ａ５において、設備１〜３に対応して機器、部品、部位等からなる各階層構造が形成されるとする。また、部品レベルの構成要素である車軸Ａ５ａ、Ａ５ｂ、Ａ５ｃは、ほぼ同様の仕様を有しているとする。
【０１０４】
これにより図５に示す設備管理システムでは、各設備毎に、前述したように図６に示す「損傷形態マトリックス表」から図９、１０に示す「損傷実態マトリックス表」を作成し、さらに図１４に示す個々の設備の部品レベルの設備実態摘要表を作成する。次いで、これらの各設備毎の設備実態摘要表を図１７に示すフォーマットの表示形式に纏めて表示装置３７条に画面表示する。
【０１０５】
通常、一つの発電所あるいは同一電力会社の中に、複数個の同型設備を有することは決して稀ではなく、これらの設備間の損傷状況の進行状況を比較検討して、特定の機器の劣化進行特性を把握するための努力は、むしろ、日常的に行われている。このような同型設備においては、その階層構造は必然的に同じとなるため、その任意の階層（レベル）での各設備毎の設備実態摘要表、例えば、図１４に示す設備実態摘要表Ｍ６を作成して図１７の設備実態摘要表Ｍ９（車軸の設備実態摘要表Ｍ９ａ、Ｍ９ｂ、Ｍ９ｃを並列表示した例を示している）として表示することにより、それぞれの設備に属する複数の同型機器の損傷度合の進行状況の比較ができるのみならず、詳細情報の分析により、その特性に対する一般的な法則の有無を検討することも容易になる。
【０１０６】
なお、図１７から明らかなように、必ずしも同型設備である必要はなく、設備実態摘要表Ｍ９の最左列の構成さえ同じであれば良い訳で、仕様が同一形式で表示できる構成要素であれば良く、さらには同一設備における仕様が同一形式の複数の構成要素（例えば、下位階層に同様構成要素に展開可能な複数の給水ポンプなど）についても同様に実施できる。
【０１０７】
次に、本発明の第１実施の形態のさらに別の変形例について図１８及び図１９を参照して説明する。
【０１０８】
この例は、図９あるいは図１０に示す「損傷実態マトリックス表」の各セルの損傷実態表示に、異常評価レベルのみならず、「点検待ち」、「点検中」、「評価中」等の作業状態値を表示するようにしたものである。
【０１０９】
まず、図５のデータ入力部１０によるデータの取込み処理時に当該データの採取状況に応じて、次のようにして決定する。
「点検待ち」：該当データ未採取の状態（入力帳票は出力されているが未入力）
「点検中」 ：該当データの採取が部分的になされているが、未完了の状態
「評価中」 ：該当データの採取は完了しているが、データの妥当性が確定できていない状態
【０１１０】
また、これらの状態値表示の優先順序は、例えば、時系列的に最も遅れているものを優先するものとすれば、「点検待ち」＞「点検中」＞「評価中」の順序で表示される。これらの状態値の表示を、異常評価レベルより優先させて上位集約表示を行うと、例えば、機器体系の設備レベルで、各機器での点検と評価の状況を一覧でき、作業の遅れを含めた設備実態の把握が可能となる。図１８はその一例を示すもので、図１５（Ｂ）に適用した設備実態摘要表を変形した例を示すものである。
【０１１１】
図中の設備実態摘要表Ｍ１０の作業状態値表示Ｍ１０ａ、Ｍ１０ｂ、Ｍ１０ｃは、図１０の損傷実態マトリックス表Ｍ４にも適用でき、その例を図１９に示している。この図１９の損傷実態マトリックス表Ｍ１１のセルＭＡの表示「点検待ち」は、部位（カップリング）の損傷形態（振れ）についての点検が未施工であることを示している。この未施工状態値が異常レベルよりも優先としたため、部位であるカップリングとしての部位評価結果Ｍ１１ａおよび車軸としての部品評価結果Ｍ１１ｃも「点検待ち」という表示となる。このように、損傷実態マトリックス表への作業状態値の導入により、ここでは、「カップリングの振れ計測」という点検項目の実施を督促する画面を構成することができる。
【０１１２】
図２０は、本発明の第２実施の形態を示す設備管理システムの構成図である。
【０１１３】
図２０において、第１実施の形態を示す図５と同一符号は、同一部分又は相当部分を示し、重複部分の説明は省略する。
【０１１４】
図２０において、設備管理システム１００Ａのセル処理部３１Ａでは、第１実施の形態のセル処理部３１にセル処置方法決定部１３を追設している。また、部位処理部３２Ａでは、第１実施の形態の部位処理部３２に部位処置決定部１６を追設している。また、部品処理部３３Ａでは、第１実施の形態の部品処理部３３に部品処置方法決定部１９を追設している。さらに、設備管理システム１００Ａは、処置方法出力部３９を追設している。
【０１１５】
ここで、セル処置方法決定部１３は、セル判定結果出力部３から評価判定の結果を取り込み、予め処置方法を定義保存する後に説明する処置方法決定テーブルを参照して、対応する各評価対象の処置方法を決定して処置方法情報を出力するものである。
【０１１６】
部位処置方法決定部１６は、部位判定結果出力部６から総合評価判定の結果を取り込み、予め処置方法を定義保存する後述する処置方法決定テーブルを参照して、対応する総合評価判定対象の処置方法を決定して処置方法情報を出力するものである。
【０１１７】
部品処置方法決定部１９は、部品判定結果出力部９から上位評価判定の結果を取り込み、予め処置方法を定義保存する後述する処置方法決定テーブルを参照して、対応する上位評価判定対象の処置方法を決定して処置方法情報を出力するものである。
【０１１８】
図２１は、第２実施の形態で用いる損傷実態マトリックス表Ｍ１２を示し、この損傷実態マトリックス表Ｍ１２は、図１０の損傷実態マトリックス表Ｍ４に対して部位処置方法Ｍ１２ａの欄を追加したものである。
【０１１９】
また、図２２は、処置方法を決定するために使用する処置方法決定テーブル１２を示し、処置方法決定テーブル１２は、損傷実態マトリックス表Ｍ１２の部位毎に、その部位に登録されている管理対象の損傷形態の数だけの枚数（図２２では、１２（１）、１２（２）、・・・・・、１２（ｎ）のｎ枚）が準備されている。
【０１２０】
この処置方法決定テーブル１２の機能について図２２に示す処置方法決定テーブル１２（１）を使用して説明する。
【０１２１】
処置方法決定テーブル１２（１）は、当該損傷形態１が予め設定された区分けである損傷レベル１２ｃと、それに対応して定まる処置方法１２ｄと、セル判定結果出力部３から送信される実際の損傷形態の実態としての損傷度合判定値f realの格納セル１２ａおよび、損傷度合判定値f realと処置方法１２ｄと対応させて予め設定された損傷レベル１２ｃ（ｆａ₁₁、ｆａ₁₂、・・・、ｆａ₁₅）」との関係を調整するための損傷レベル調整ロジック１２ｂとで構成されている。
【０１２２】
損傷レベル１２ｃと処置方法１２ｄの組合せは、例えば処置方法として最も軽度な損傷レベルｆａ₁₁に対応する処置方法Ｓａ₁₁は、通常、Ｓａ₁₁：最小限の手入れで、そのまま使用とする。逆に、最も厳しい損傷レベルｆａ₁₅に対応する処置方法Ｓａ₁₅は、Ｓａ₁₅：部品Ａの新品交換というように定めている。
【０１２３】
このようにして予め設定した損傷レベルの区分け（ｆａ₁₁、ｆａ₁₂、・・・、ｆａ₁₅）と処置方法１２ｄとがシステムによって適切に対応しない場合があり、その場合に損傷レベル調整ロジック１２ｂの調整を行う。
【０１２４】
図２２の例では、設備管理システム１００Ａが使用する損傷度合評価区分を、例えば、「正常」、「注意」、「異常」としたとき、処置方法決定テーブル１２（１）の損傷レベル調整ロジック１２ｂでは、「注意」をｆａ₁₁とｆａ₁₂とのＯＲ条件とし、「異常」をｆａ₁₃とｆａ₁₄とｆａ₁₅とのＯＲ条件として関係づけている。
【０１２５】
なお、例えば、「注意」をｆａ₁₁またはｆａ₁₂等のＯＲ条件としたのは、該当する処置方法をそのまま並列表示してシステム使用者による選択事項としても良いし、損傷形態の実態としての損傷度合判定値f realに応じて処置方法の自動選択が可能なようにするためである。
【０１２６】
セル処置方法決定部１３は、処置方法決定テーブル１２を用いて決定した当該部位に属する各損傷形態の損傷度合に応じた処置方法の候補を処置方法出力部３９に送信する。
【０１２７】
処置方法出力部３９は、例えば、図２１の損傷実態マトリックス表Ｍ１２上の部位処置方法表示Ｍ１２ａの部位毎表示セル；Ｍ１２ｂ〜Ｍ１２ｇ・・・、等の当該セルがクリックされると、別のウィンドウを呼び出し、その該当部位の処置方法を表示する。例えば、図２１の部位毎の処置方法も表示するセルＭ１２ｂに対しては図２３の部位処理表示例Ｂ１のＢ１ａの内容が対応して表示される。また、図２１の部位毎の処置方法表示セルＭ１２ｃに対しては図２３のＢ１ｂの内容が対応して表示される。
【０１２８】
部位処置方法決定部１６は、セル処置方法をそのまま集めて部位全体の処置方法をリストとしてまとめるものであり、図２１の部位処置方法表示Ｍ１２ａをクリックすると、例えば、図２３の部位処置方法リストと部位処置方法出力位置情報を処置方法出力部３９に出力して、別ウィンドウで表示する。
【０１２９】
図２３は、図２１において「正常」以外の評価となっている全ての損傷形態について、その損傷度合に応じた処置方法を並列表示している。図２３の各行が各セルに対応した処置方法であり、これを部位単位で見ると、部位処置方法となる。例えば、部位「本体胴」については、損傷形態「振れ」と「傷」の２個所が評価対象となっているため、図２３では、処置方法を示すセルＢ１ａがそれぞれの損傷形態に対して並列表示されている。なお、図２１の部位処置方法Ｍ１２ｄとＭ１２ｅは、評価結果が「正常」であるため、図２３には表示されていない。
【０１３０】
また、システム使用者は、このウィンドウに表示された内容を適宜見直して（不適切な処置方法を排除、あるいは集約など）新たな処置方法にまとめ直して、部位処置方法として登録できる。部位処置方法決定部１６は、システム使用者による修正内容を優先させる。例えば、図２３の「本体胴」に対する２つの損傷形態（振れ、傷）に対する処置を、図２４に示す部品処置方法表示例Ｂ２の例のようにまとめることもできる。
【０１３１】
次に、部品処置方法決定部１９が、部位処置方法決定部１６で決定された各部位の処置方法を受取り、それらをそのまま集めて、部品全体の処置方法リストとしてまとめる。さらに、図２１の部品処置方法表示Ｍ１２ｈがクリックされると、例えば、図２４の部品処置方法表示例Ｂ２と部品処置方法の出力位置情報を処置方法出力部３９に出力して、別ウィンドウで表示する。
【０１３２】
ここで、図２４は、図２１の部品処置方法表示のセルＭ１２ｈに該当する表示例であり、図２３の部位レベルの処置方法の部品処置方法への変換事例である。
これは、図２３の部位処置方法リストのマトリックス表の中で互いに関連する事項をシステム使用者により集約表示した例で、図２３の処置方法Ｂ１ａと処置方法Ｂ１ｃを集約し、図２４の処置方法Ｂ２ａを作成し、同様に図２３の処置方法Ｂ１ｂと処置方法Ｂ１ｄを集約し、図２４の処置方法Ｂ２ｂを作成したものである。
【０１３３】
従って、システムによって自動的に部品処置方法を出力する場合には、図２３のように当該部品のセル処置方法リストの出力となるが、部位処置方法決定部１６と同様に、部品処置方法決定部１９にもシステム使用者による編集機能を持たせることにより、図２４のような集約された処置方法の出力が可能となる。
【０１３４】
次に、本発明の第２実施の形態の変形例について図２５乃至図２７を参照して説明する。
【０１３５】
この例は、図２０の部位処置方法決定部１６で定義される部品単位での処置方法を機器とその構成要素である部品の関係に従って、機器としての処置方法として集約し、さらに、装置と機器、機器と装置という設備体系の階層間でも同様に、一つ下の階層レベルでの処置方法を一纏めに集約すると共に、図１４乃至図１５（Ｂ）の説明で設備実態摘要表を展開したのと同様に、その下位展開も可能とするものである。
【０１３６】
まず、図２１の損傷実態マトリックス表Ｍ１２は、その元となっている図１０の損傷実態マトリックス表Ｍ４を図１４の設備実態摘要表Ｍ６に変換したと同様の処理によって図２５に示す部品レベルの設備実態摘要表Ｍ１３に変換する。
【０１３７】
図２５の設備実態摘要表Ｍ１３は、図１４の設備実態摘要表Ｍ６に、部位評価結果表示セルＭ６ｂに対応した部位評価結果表示セルＭ１３ｂに部位処置方法表示セルＭ１３ｃを追加し、部品評価結果表示セルＭ６ａに対応した部品評価結果表示セルＭ１３ｄに部品処置方法表示セルＭ１３ｅとを追加したものである。部位評価結果表示セルＭ１３ｂの任意の部位該当個所を選択すると、別ウィンドウが呼び出され、当該ウィンドウに、図２３の処置方法の中から該当する部位の処置方法が選択表示される。同様に、部品処置方法表示セルＭ１３ｅが選択されると、図２４の部品処置方法が表示される。
【０１３８】
図２５の設備実態摘要表Ｍ１３は、図１４の設備実態摘要表Ｍ６に、前述の如く、部位処置方法表示セルＭ１３ｃと部品処置方法表示セルＭ１３ｅを追加した構成としているので、設備実態摘要表Ｍ１３も上位集約が可能となる。従って、図１５（Ａ）および図１５（Ｂ）に対応して、図２６の機器レベルの設備実態摘要表Ｍ１4および図２７の設備実態摘要表M１５を得ることができる。
【０１３９】
逆に、図２７の設備実態摘要表Ｍ１５から図２６の設備実態摘要表Ｍ１４、図２５の設備実態摘要表Ｍ１３への下位展開も可能であり、設備実態摘要表Ｍ１３から図２１の損傷実態マトリックス表Ｍ１２への逆変換も可能となる。
【０１４０】
このような処置方法の上位集約は、部位から部品への上位集約時に使用した図２３から図２４への変換手法がそのまま適用できる。この変換の過程において人間系での修正を加えない限り、機器体系の上位に行くに従って処置方法リストは大きくなるが、設備実態摘要表Ｍ１３〜Ｍ１５には、これらのリストの呼び出し機能のみが搭載されているため、これらの上位集約操作に支障を来すことは無い。
【０１４１】
なお、このような処置方法は、機器体系の下位レベルから決定され、機器体系の上位レベルに向かって上位集約を行いながら各レベル毎に段階的に決定されて行くため、下位展開する場合にも各レベル毎に段階的に表示することができる。
【０１４２】
また、このような上位集約表示あるいは下位展開表示を任意に行うことにより、機器体系の任意のレベルでの設備実態摘要表から、そのレベルの設備あるいは機器に対応する処置方法を呼び出してマトリックス展開表示とすることが可能となるため、システム使用者が必要とするレベルでの情報を効率的に入手することができる。
【０１４３】
次に、本発明の第３実施の形態について図２８及び図２９を参照して説明する。
【０１４４】
第３実施の形態は、第１実施の形態の損傷形態マトリックス表において、管理対象となる部位とその部位に対応する損傷形態との交点（マトリックス表のセル）に、当該損傷形態の管理方法を示す管理形態名を入れた「管理形態マトリックス表」を表示し、この管理状態表示を色分け等の表示で行うものである。
【０１４５】
本発明に基づく設備管理システムは、機械部品に対する観察の結果としての図６に示す損傷形態マトリックス表Ｍ２から出発し、当該機械部品の損傷実態を明確にするための図１０の損傷実態マトリックス表Ｍ４、あるいは図２１の損傷実態マトリックス表Ｍ１２を導くことを基本として構成されているが、これを火力発電プラント用として展開する場合には、当該分野での以下に述べるような特殊条件を加味することによって、さらに使い易いものとすることができる。
【０１４６】
今、火力発電プラントを構成する各設備に関し、それに従属する各種の機器・部品・部位に発生し得る各種の損傷形態について、その発見の方法から追跡調査、対策処置の実施までの一連の管理方法を分析してみると、幾つかのパターンが成立することが分かっている。図２８は、そのパターンを管理形態として分類定義した管理状態の定義表Ｃ１である。火力発電プラントにて発見される損傷形態の殆ど全てがこの分類で整理される。
【０１４７】
図２８に示される管理形態の定義表Ｃ１を、図１０の損傷実態マトリックス表Ｍ４の各損傷形態に適用すると、それぞれの損傷形態の実際の管理方法に応じて、＊印を管理形態名に置き換えることができ、これに、部位処置方法表示セルと部品処置方法表示セルを追加することにより、図２１に示す損傷実態マトリックス表Ｍ１２と同フォーマットの図２９のような新たに管理形態マトリックス表Ｍ１６が得られる。
【０１４８】
この管理形態マトリックス表Ｍ１６は、各部位に発生し得る損傷形態の管理方法を示すマトリックス表にもなり、当該損傷形態の点検のために適用すべき管理形態を知ることができ、実施すべき業務の概要まで知ることが可能になる。
【０１４９】
また、この管理形態マトリックス表Ｍ１６に表示される全ての管理形態が、必ずしも毎定期点検で実施されるわけではないことにも注意が必要である。例えば、図２８に定義されている「余寿命」は、１０年ピッチ程度の長周期で実施されるのが普通であり、任意の定期点検時を考えた場合には、当該管理形態はスキップされることも有り得る。このような場合には、当該管理形態のセルを無効（選択しても不作動）とすることが望ましい。これは、管理形態マトリックス表Ｍ１６が、定期点検で実施すべき点検業務の管理にも使えることを意味しており、いろいろな利用が考えられる。
【０１５０】
なお、管理形態マトリックス表Ｍ１６に図２１の損傷実態マトリックス表Ｍ１２の機能を持たせるためには、損傷実態マトリックス表Ｍ１２での損傷実態の「正常」「注意」「異常」という文字表現での評価レベルの代りに、例えば、管理形態名称の表示はそのままにして、それぞれを、緑、黄、赤 等の色表示とすることにより達成される。このように、損傷レベルの色表示を伴う管理形態マトリックス表を、新たに損傷実態マトリックス表と同様に実施すれば、設備実態摘要表への変換等は、異常評価レベル表示の代わりに、この色表示を使用することでそのまま生成でき、第１実施の形態及び第２実施の形態と同様に摘要して実施することができる。
【０１５１】

These systems are equipped with a large number of devices and parts constituting the devices in order to realize the functions required for the system.
[0003]
In order to keep the power plant with such a complicated configuration in a state where it can be properly operated as a whole at all times, it is possible to take appropriate measures at an appropriate time while grasping the status of each component device. Thus, an equipment management system is provided.
[0004]
Conventional facility management systems have been developed only for systems that mainly support human systems and support fragmented maintenance work locally, or systems that limit the support target to a narrow range.
[0005]

There was a problem that it took time to grasp the actual state of damage and was extremely inefficient.
[0008]
Secondly, the management table created for each device or equipment must be created entirely in the event of new damage that has not yet been experienced due to long-term operation of the plant. There was a problem of being uneconomical.

DETAILED DESCRIPTION OF THE INVENTION
Prior to the description of embodiments of the present invention, first, an overview of a damage form evaluation method for each component to be managed, particularly a “damage form matrix table” will be described.
[0026]
In general, a large-scale system represented by a power plant is composed of a plurality of systems composed of a large number of facilities, and these facilities are composed of a single device or a plurality of devices and devices, and each device is composed of a plurality of systems. Each is composed of many parts. In the present invention, from the viewpoint of maintenance and management related to plant facilities, each component constituting the plant can be expanded from the upper level to the lower level, such as facilities, devices, equipment, parts, parts, and so on. To the hierarchical structure that can be aggregated to the upper level, determine the damage status of each component that belongs to the lowest level among the journalized levels, and then evaluate retroactively to the higher level components, It is designed to grasp the damage situation.
[0027]
That is, generally speaking, the hierarchical structure in the plant can be expressed by the following system (a).
Equipment-Equipment-Equipment-Parts ... (a)
From the viewpoint of grasping the degree of damage in (a) above, it is not sufficient to simply start with parts that can be physically separated. For these important parts, the functions are further different. It is necessary to divide the parts into several lower layer parts to be evaluated, and evaluate the aggregated damage state of these parts as a damage actual state of the part. This is referred to as a part, and the hierarchical structure of the plant considering such points can be expressed as shown in (b) below.
Equipment-equipment-equipment-parts-parts ... (b)
Moreover, even if it is the same part, when the part has a plurality of management targets, it is possible to grasp the situation more accurately and easily by further expanding to the detailed part and subdividing the information. In such a case, it can be represented by the following hierarchical structure (c).
Equipment-Device-Equipment-Parts-Parts-Detailed parts ... (c)
[0028]
Accordingly, the plant status is such that the plant components are arranged in the hierarchical structure as described above in (a) to (c), and the status information of each component in each hierarchy is sequentially arranged from the lower hierarchy to the upper hierarchy. This makes it possible to grasp accurately.
[0029]
FIG. 1 shows an example of a plant system in which the above-described general plant hierarchical structure is applied to steam turbine equipment. The system A1 of the uppermost turbine facility (equipment) in FIG. 1 has a turbine body, main valves, control and security devices, a condenser, a feed water superheater, etc. at a lower hierarchy (equipment) than the turbine facility. A lower level (components) than (equipment) has a casing, an axle, a moving blade, a stationary blade, and a nozzle box. For proper maintenance of plant equipment, the system is expanded to the equipment, equipment, or individual parts that make up the equipment, parts of each part as necessary, and even detailed parts. It is important to accurately capture the actual situation down to the necessary and sufficient level.
[0030]
For example, the nozzle box which is a component shown in A1a of FIG. 1 has an appearance as shown in FIG. 2, and the nozzle box 50 includes a plurality of units including a main body 50a, a structural weld 50b, and a chest ring 50c. FIG. 3 shows a system A2 of the nozzle box 50 corresponding to FIG. 1 and FIG. 2, and the situation of the nozzle box (component) 50 is the situation of the main body (part), the situation of the structural welded part (part), and the check string. (Section) will be combined. In addition, the status of the main body (parts) is the detailed part that constitutes the damage status of the steam chamber, seal ring, horizontal joint female thread, upper and lower half-tightening bolts, hold-down bolts, and adjustment parts. It is a collection. The same applies to structural welds (parts) and chest strings (parts).
[0031]
Next, considering the damage status of each component at the detailed part level of the main body, the form of damage that can occur in each component during long-time operation under a predetermined condition is empirical. Or, it is within a range where design can be sufficiently predicted. However, such a damage form is not limited to one for each component, and there are often a plurality of damage forms. In general, let us summarize the damage forms at a higher level (here, the part level). Then, it is easier to understand if the format is a matrix table in which rows and columns correspond to each other.
[0032]
FIG. 4 shows an example of the damage form matrix table.
[0033]
FIG. 4 is directed to the main body (part) 50a of the nozzle box (part) 50 shown in FIG. 2, and the detailed part M1a is taken on the vertical axis (column direction) and the damage form M1b is taken on the horizontal axis (row direction). The developed damage form matrix table M1.
[0034]
Specifically, the detailed part M1a includes each component of “steam chamber”, “seal ring”, “horizontal joint female thread part”, “upper and lower half tightening bolt”, “hold down bolt”, and “adjustment part”. On the other hand, in the damage form M1b, “crack”, “erosion”, “lifetime consumption”, “deformation”, “galling”, and “gap” are described. In FIG. 4, among the cells formed at the intersections of rows and columns, * marks are given to locations where the constituent elements (detailed parts) to be managed or evaluated and the damage forms are mutually related. ing.
[0035]
In this way, the “damage form matrix table” can be applied to hierarchically expanded plant components such as, for example, equipment-part-part, and as shown in FIG. ) Are arranged in the column direction, while the damage forms that can occur in each component are arranged in the row direction, and the cells that intersect each other are related to each other. It is formed with a mark.
[0036]
Then, the “damage form matrix table” is displayed in the cell corresponding to each part and the damage form corresponding to that part as an example shown in FIG. By displaying the actual state (damage actual state), the actual damage state of each part of the part is displayed as a list as a “damage actual state matrix”. In addition, this “damage actual state matrix table” is a comprehensive evaluation determination result obtained by comprehensively evaluating and determining the actual damage in each damage form of each part that is each component as shown in FIG. Are displayed in the cells (M4c1, M4c2,...) In the rightmost column of the row.
[0037]
Furthermore, as shown in FIG. 10, the evaluation results of the respective parts entered in the cells (M4c1, M4c2,...) In the rightmost column of the “damage actual state matrix table” are aggregated in the column direction (vertical direction). The result of the evaluation judgment of the part summarizing the part (higher evaluation judgment result) is displayed in the cell (M4e) in the bottom column of the column. In other words, the composition of the upper hierarchy that aggregates all the components (parts) of one hierarchy by aggregating the overall assessment judgment results for each component found in the “damage actuality matrix table” and making a comprehensive assessment judgment Element (part) loss Wound The actual condition can be determined, and the result is displayed in the cell (M4e). In the present invention, this “damage actual state matrix table” is further developed and shown in FIG. 14 and FIG. The “facility summary table” is displayed.
[0038]
As described above, according to the present invention, the above-mentioned “damage actual state matrix table” allows the actual state of the damage form of each component constituting the plant to be immediately grasped, and the “facility actual state summary table” provides these. This makes it possible to grasp in a short time the actual state of damage of each component in the upper hierarchy where the components are aggregated. At the same time, from the actual state of the damage form of each component in the upper layer, the actual state of the damage form of each component in the lower layer where these components are developed can be grasped.

In this example, assuming that the part obtained by developing a part that is one of the hierarchies is the minimum unit of management evaluation, a damage form matrix table for judging the damage form of each component constituting the part is displayed. ing.
[0057]
That is, in FIG. 6, regarding the component called the axle of the steam turbine main body, each component (main body trunk, heat groove, labyrinth portion) constituting the part that is one level below is taken in the row direction, A matrix is formed with all the damage forms (cracks, vibrations, contact marks...) Considered to occur in each component in the row direction. If there is a damage form that can occur in each component among the cells that form the intersections, a mark * is attached to the relevant part to form a damage form matrix table M2.
[0058]
It should be noted that the relationship between each component and each form of damage cannot be fixed, new damage may occur to a certain component, and unexpected damage may occur to an unexpected component. In some cases, it is necessary to expand to a lower hierarchy. In order to realize a management system that can cope with this situation during system operation, the number of components and the number of damage modes should be changed at any point in time. It is necessary to keep.
[0059]
In the example of FIG. 6, a column of an arbitrary part M2a and damage form M2b on the damage form matrix table M2 with a symbol *, for example, in FIG. 6, the part “body trunk” M2a1 and the damage form “crack”. The cell MA corresponding to M2b1 displays the evaluation determination result of the degree of damage of a specific form of damage that can occur (here, the degree of progress of cracks to the body cylinder). That is, for each cell to which all symbols * on the damage form matrix table M2 represented by the cell MA are attached, the damage occurrence state in the corresponding damage form is evaluated.
[0060]
FIG. 7 is a configuration diagram of the damage degree evaluation method definition table 11 that defines and stores an evaluation method for performing evaluation determination for each cell displayed in the damage form matrix table M2 of FIG.
[0061]
As shown in FIG. 7, the damage degree evaluation method definition table 11 has the following combinations (d) to (f) corresponding to the number n of damage forms that can occur in the part a of the part A corresponding to the row direction of the cell. And n cell damage degree evaluation method definition sheets 11 (1), 11 (2),..., 11 (n).
Judgment item (p ₁₁ , P ₁₂ , ..., p _1m ) ... (d)
Judgment value (q ₁₁ , Q ₁₂ , ..., q _1m (E)
Judgment method (j ₁₁ , J ₁₂ , ..., j _1m ) ... (f)
Here, the judgment item p ₁₁ Is j ₁₁ Q according to the determination method defined in ₁₁ Is evaluated as a judgment value.
[0062]
Note that the function f (p outside the cell in the cell damage degree evaluation method definition sheet 11 (1) ₁₁ , P ₁₂ , ..., p _1m ) Generally indicates a case where there are m determination items for the cell a1 (combination of the part a and the damage form 1), and the evaluation result of the cell a1 is the determination item (p ₁₁ , P ₁₂ , ..., p _1m ) As a function. Here, the judgment item (p ₁₁ , P ₁₂ , ..., p _1m ) Need not be plural, for example, p ₁₁ It may be possible to evaluate with only one of these.
[0063]
Since the evaluation method can be defined independently for each cell in this way, it is possible to flexibly cope with later changes or additions of the evaluation method.
[0064]
FIG. 8 is a specific configuration diagram of the cell damage degree evaluation method definition table shown in FIG. 7, and is developed by taking the “main body trunk” of the part M2a in FIG. 6 as an example. That is, four damage forms (cracks, vibrations, contact traces, and magnetization) are defined as shown in FIG. 6, and the damage degree evaluation method definition sheet 11 (n) shown in FIG. Created against.
[0065]
Accordingly, the cell damage degree evaluation method definition table “body trunk” has a total of four cell damage degree evaluation method definition sheets 4 (1), 4 (2), 4 (3), 4 (4) as shown in FIG. 4).
[0066]
Thus, the damage degree evaluation method definition sheet 11 (n) defined for each cell is collected as a damage degree evaluation method definition table 11 for each part, and is managed by the cell damage degree evaluation method definition unit 1.
[0067]
For example, when the cell MA in the damage form matrix table M2 shown in FIG. 6 displayed on the display device 37 is activated (the region M2a1, the damage form M2b1, and the intersection cell are selected with the mouse), the position of the cell MA is determined. The cell position identification information is read, and the corresponding damage degree evaluation method definition sheet 11 (n) of the damage degree evaluation method definition table 11 as shown in FIG. 7 for the corresponding cell MA of the cell damage degree evaluation method definition unit 1. Is selected.
[0068]
Subsequently, the cell damage degree evaluation method definition unit 1 determines the determination items defined in the damage degree evaluation method definition sheet 11 (n) selected by adding the cell position identification information and the damage actual state corresponding thereto. The data input unit 10 is requested for actual measurement data to be used. The data input unit 10 takes in data corresponding to the determination item from an arbitrary database 34 in which actually measured data is stored in advance. Alternatively, data is directly captured from the data capture sensor 35 corresponding to the determination item. Then, cell position identification information and determination items corresponding to the captured actual measurement data are attached and output to the cell damage degree determination unit 2.
[0069]
Next, in the cell damage degree determination unit 2, the determination method of each determination item in the cell damage degree evaluation method definition sheet 11 (n) of the damage degree evaluation method definition table 11 defined by the cell damage degree evaluation method definition unit 1 The degree of damage is determined from actually measured data taken from the data input unit 10 using an evaluation method based on the determination value. As the determination result, for example, levels such as “normal”, “caution”, and “abnormal” are classified according to the degree of the comparison result with the determination value, and the determination result is the cell determination result output unit as the actual state of damage. 3 is sent. The method of dividing the determination results into levels is defined in the determination method of the cell damage degree evaluation method definition table 11 (n).
[0070]
Next, the cell determination result output unit 3 displays the determination result via the damage degree determination result output unit 36 based on the determination result sent from the cell damage degree determination unit 2 and the corresponding cell position identification information. This is displayed on the damage form matrix table displayed on the device 37.
[0071]
For example, when the occurrence state of each damage form is displayed in each cell of the steam turbine / axle damage form matrix table M2 of FIG. 6, a damage actual state matrix table M3 is obtained as shown in FIG. This damage actual condition matrix table M3 has a part M3a on the vertical axis and a damage form M3b on the horizontal axis, and “normal”, “caution”, “ Different "Normal" is displayed.
[0072]
Next, the determination result regarding each cell of the cell damage degree determination unit 2 is sent to the part damage degree determination unit 5, and in accordance with the comprehensive evaluation method defined by the part damage degree evaluation method definition unit 4, Evaluation evaluation is performed. The result is output to the part determination result output unit 6. The comprehensive evaluation method defined in the part damage degree evaluation method definition unit 4 is generally expressed by the following (g) as a function of the determination results of all cells belonging to the same part.
[0073]
fp (α _a1 , Α _a2 , ..., α _an ) ... (g)
[0074]
Where α _a1 , Α _a2 , ..., α _an Is a determination result of n damage forms 1, 2,..., N in a specific part a. In this simplest case, if the determination result of each cell is determined in the simple steps of “normal”, “caution”, and “abnormal”, the function fp is expressed as α _a1 , Α _a2 , ..., α _an A method of selecting the most severe of the above can be considered. In addition, the evaluation formula represented by the above (g) before correcting to the simple steps of “normal”, “caution”, and “abnormal” described above is passed to the site damage degree evaluation method definition unit 4, It can also be evaluated by the above function.
[0075]
Next, the part determination result output unit 6 adds part determination result output position information to display the evaluation result as the part thus determined on the damage actual state matrix table M3 shown in FIG. The data is delivered to the determination result output unit 36 and displayed on the display device 37 as a damage actual condition matrix table M4 shown in FIG. This damage actual condition matrix table M4 is provided with a part evaluation result cell M4c in the vertical direction in the rightmost cell of the damage actual condition matrix table M3 in FIG. 9, and displays the result of comprehensive evaluation determination in the same part.
[0076]
Next, the result of the comprehensive evaluation determination obtained by the part damage degree determination unit 5 is sent to the component damage degree determination unit 8, and in accordance with the upper evaluation determination method defined by the part damage degree evaluation method definition unit 7, And the result is output to the component determination result output unit 9 as a higher evaluation determination result.
[0077]
The determination method defined in the component damage degree evaluation method definition unit 7 generally includes determination results of all parts (assumed as parts a to q) belonging to the same part; βa, βb,. It is expressed by the following (h) which is a function of βq.
[0078]
fe (βa, βb,..., βq) (h)
[0079]
Again, as the simplest function form, the most severe one of the determination results βa, βb,..., Βq of each part is selected.
[0080]
In the part determination result output unit 9, in the damage actual condition matrix table M3 in FIG. 9, the output position information of the upper part determination result is displayed in order to display the result of the upper evaluation determination as a part summarizing the whole part as shown in FIG. Is displayed on the display device 37 via the damage degree determination result output unit 36. For example, the part evaluation result cell M4e provided at the bottom of the rightmost cell M4c of the damage actual state matrix table M4d in FIG. 10 is displayed.
[0081]
As described above, since the cell processing unit 31, the part processing unit 32, and the part processing unit 33 are defined in units of the damage form matrix table shown in FIG. 6, the management target device-part-part and damage as the equipment management system It can be expanded according to the range of the form, and it can be said that the expandability to the system support range is very high.
[0082]
The level of the site of the damage actual state matrix table M4 shown in FIG. 10 is not always uniform, as can be seen from the steam turbine equipment system A3 in FIG. 11 and the labyrinth equipment system A4 in FIG. Absent.
[0083]
That is, in the system A3 of FIG. 11, the labyrinth part is represented as a part, but when it is going to confirm the details further, it is easier to understand if it is developed as a labyrinth part like the system A4 shown in FIG. There is. Therefore, when such a concept is applied to the damage actual state matrix table M4 in FIG. 10, for example, a damage actual state matrix table M5 as shown in FIG. 13 is obtained.
[0084]
In FIG. 13, each cell of the labyrinth part as a part is hatched, which means that the entire labyrinth part is evaluated with a matrix having a configuration different from that of the other part of the lower hierarchy. is doing. “Normal” in the part evaluation result cell M5a displays the result of the comprehensive evaluation determination in the matrix table. This is because the damage actual state matrix table M4 in FIG. 10 arbitrarily defines another matrix when the damage form is hierarchically different from other parts in the same row as in the modified display example of FIG. It shows that you may do.
[0085]
As described above, according to the present embodiment, it is possible to provide an equipment management system that can flexibly cope with changes in various equipment management methods that are expected to occur in the future in the following points.
[0086]
First, by introducing the damage form matrix table, the actual state of damage can be grasped at a glance, and it is possible to easily cope with the increase or decrease in damage forms and occurrence sites to be managed.
[0087]
Secondly, since the damage degree evaluation method can be constructed on each cell of the matrix table, it is possible to easily cope with changes in the evaluation criteria, the evaluation method, etc. by only partial correction of the database.
[0088]
Third, using the structure of the matrix table, for example, the cell damage degree evaluation method is applied to each cell, the part damage degree evaluation method is applied to each row (part), and the component damage degree evaluation method is applied to the rightmost cell column (part). As a result of the allocation, it is possible to change the evaluation method as a part (upper level of the equipment system) without affecting other parts, and to create an economical system that matches the actual situation of facility operation. Can do.
[0089]
In the embodiment described above, the table data storage means has been described as being provided in the cell damage degree evaluation method definition unit 1, but the present invention is not limited to this, and may be appropriately stored, for example, in the database 34. It can be provided at the location. In addition, it is obvious that the system configuration can be freely changed as appropriate, such as the definition units 1, 4, and 7 being provided in the database 34.
[0090]
Next, a modification of the first embodiment of the present invention will be described with reference to FIGS. 10, 14 to 15 (B).
[0091]
In this example, the component level equipment actuality summary table M6 shown in FIG. 14 is created based on the part level damage actuality matrix table M4 shown in FIG. The equipment level equipment actuality summary table M7 shown in FIG. 15A is created, and the equipment level equipment actual situation summary table M7 shown in FIG. A table M8 is created.
[0092]
First, in the damage actual condition matrix table M4 shown in FIG. 10, the rightmost column cell which is a part name corresponding to the part M4a constituting the target part of the damage actual condition matrix table M4 and the evaluation result of the damage actual condition of each part. When the part evaluation results M4c are combined in correspondence with each other, the equipment actual condition summary table (part level) M6 shown in FIG. 14 can be created. FIG. 14 is a list including a damage actual condition M6a at a part (axle) level and a damage actual condition (evaluation result) M6b at each part constituting the part (axle). These table creation processes may be performed by the damage degree determination result output unit 36, and such a processing unit may be provided in the display device 37 and provided at an appropriate location in the facility management system 100. Can do.
[0093]
Next, when the equipment actual condition summary table M6 as shown in FIG. 14 is determined for all the related parts and parts, the equipment actual information on the higher-level equipment according to the equipment system to which the parts and parts belong. Can be aggregated.
[0094]
That is, for the sake of simplicity,

Suppose that each of the turbine systems A3 has a hierarchical structure as shown in FIG.
[0095]
The part (axle) level facility actuality summary table M6 in FIG. 14 corresponds to “cabinet”, “moving blade”, “static blade”, “nozzle box” in the part level hierarchy of the system A3 in FIG. Each created. Then, the component names and the component evaluation results of the equipment actuality summary tables at the respective component levels of these “axle”, “cabinet”, “moving blade”, “static blade”, and “nozzle box” are taken in and summarized as shown in FIG. A facility actuality summary table M7 at the upper level equipment (turbine body) level shown in (A) can be created. In the facility actual condition summary table M7 in FIG. 15A, the equipment name “turbine body” and the equipment evaluation result “abnormal” are displayed in the lower cell M7a, and the part names and parts constituting the “turbine body” in the upper cell M7b. The evaluation result is displayed.
[0096]
In the same manner, a facility actuality summary table is created for each of “main valve”, “control security device”, “condenser”, and “feed water heater” belonging to the same level as the “turbine body” shown in FIG. The device name and device evaluation result of each prepared equipment summary table are captured and summarized. As a result, a facility actuality summary table at the facility (turbine facility) level shown in FIG. 15B is created. In the equipment level summary table M8 shown in FIG. 15B, the name of each equipment constituting the “turbine equipment” and the equipment evaluation result are displayed in the upper cell M8b, and “turbine equipment” is displayed in the lower cell M8a. Name and equipment evaluation result are displayed.
[0097]
As described above, when the damage actual state matrix table M4 shown in FIG. 10 for each part / part is obtained by the processing according to the present embodiment, FIG. 14 to FIG. 14 are performed according to the hierarchy of the device system used in the system based on the information. As shown in FIG. 15 (B), it can be aggregated (superordinated) into the equipment actual condition summary table at the upper level in order, and the damage situation as equipment can be expressed concisely.
[0098]
With this configuration, on the contrary, it becomes easy to know the detailed information of the problem location from the facility level summary table M8 at the facility level in FIG. For example, as shown in FIG. 15B, when the equipment evaluation result of the turbine equipment is displayed as “abnormal”, selecting a turbine body belonging to a component that is “abnormal” is a breakdown of FIG. It is possible to narrow down problem areas by calling up the equipment level equipment summary table M7 in (A) (subordinate development). Further, in FIG. 15A, when an axle displayed as “abnormal” is selected, the facility actual condition summary table M6 in FIG. 14 can be called, and further problem points can be narrowed down. Since the procedures for higher level aggregation and lower level deployment can be performed freely according to the equipment system used by the system, it is possible to refer to the actual state of equipment at a desired level.
[0099]
Next, a case will be described in which reverse conversion is performed from the component level facility status summary table M6 of FIG. 14 to the damage status matrix table M4 shown in FIG.
[0100]
As described above, the conversion from the damage actual state matrix table M4 in FIG. 10 to the facility actual state summary table M6 in FIG. 14 can be performed by simply omitting the cells of the damage form portion of the matrix table. If this relationship is stored, it can be called up and displayed from the equipment actual condition summary table M6 to the damage actual condition matrix table M4. Thereby, it is possible to reconfirm the problem location and the details of the problem while using the general information as a reference.
[0101]
Next, another modification of the first embodiment of the present invention will be described with reference to FIGS.
[0102]
This modification is an example in the case where a plant has a plurality of plant systems, that is, hierarchical structures, starting from “damage form matrix table” in each hierarchical structure, “damage actual condition matrix table”, and further “equipment actual condition summary table” Are all processed by the method described so far with the equipment management system configuration shown in FIG. In this modified example, by displaying in parallel the facility status summary table for components of almost the same specifications in the facility status overview table created in each hierarchical structure, other hierarchical structures (plant systems), that is, other This makes it easy to compare the damage status of components with almost the same specifications belonging to the equipment, and makes it possible to grasp the deterioration characteristics of the components of the same type.
[0103]
For example, in the plant system table A5 shown in FIG. 16, it is assumed that each hierarchical structure including equipment, parts, parts, and the like is formed corresponding to the facilities 1 to 3. Further, it is assumed that the axles A5a, A5b, and A5c, which are component-level components, have substantially the same specifications.
[0104]
As a result, the facility management system shown in FIG. 5 creates the “damage actual state matrix table” shown in FIGS. 9 and 10 from the “damage form matrix table” shown in FIG. Prepare the equipment level summary table at the component level for each piece of equipment. Next, the equipment actual condition summary table for each equipment is collected and displayed on the display device 37 in a display format of the format shown in FIG.
[0105]
Normally, it is not rare that a single power plant or the same electric power company has a plurality of the same type of equipment. Rather, efforts to understand the characteristics are made on a daily basis. In such an equipment of the same type, the hierarchical structure is inevitably the same, so the equipment actual condition summary table for each equipment in the arbitrary hierarchy (level), for example, the equipment actual condition summary table M6 shown in FIG. The equipment actual condition summary table M9 shown in FIG. 17 (displayed as an example of the axle equipment actual condition summary tables M9a, M9b, and M9c displayed in parallel) causes damage to a plurality of identical devices belonging to the respective equipments. In addition to being able to compare the degree of progress, detailed information analysis makes it easy to examine the existence of general rules for the characteristics.
[0106]
As is clear from FIG. 17, it is not always necessary to use the same type of equipment, and it is sufficient that the configuration in the leftmost column of the equipment actuality summary table M9 is the same, and any component whose specifications can be displayed in the same format. Furthermore, the present invention can be similarly applied to a plurality of constituent elements having the same specifications in the same facility (for example, a plurality of water supply pumps that can be developed into the same constituent elements in a lower hierarchy).
[0107]
Next, still another modification of the first embodiment of the present invention will be described with reference to FIGS.
[0108]
In this example, not only the abnormal evaluation level but also “waiting for inspection”, “under inspection”, “under evaluation” are displayed on the damage actual state display of each cell in the “damage actual state matrix table” shown in FIG. "etc The work state value is displayed.
[0109]
First, it is determined as follows according to the data collection status at the time of data acquisition processing by the data input unit 10 of FIG.
“Waiting for inspection”: The state where the corresponding data has not been collected (input form is output but not entered)
“Checking”: The data is partially collected, but not yet completed
“Under evaluation”: Data collection has been completed, but the validity of the data has not been confirmed.
[0110]
In addition, the priority order of the state value display is displayed in the order of “waiting for inspection”> “under inspection”> “under evaluation”, for example, if priority is given to the one that is most delayed in time series. The If these status values are displayed with higher priority than the abnormal evaluation level, for example, the status of inspection and evaluation at each equipment can be listed at the equipment level of the equipment system, including work delays. It is possible to grasp the actual situation of the equipment. FIG. 18 shows an example thereof, and shows an example in which the facility actual condition summary table applied to FIG. 15B is modified.
[0111]
The work status value displays M10a, M10b, and M10c in the equipment actual condition summary table M10 in the figure can also be applied to the damage actual condition matrix table M4 in FIG. 10, and an example thereof is shown in FIG. The display “waiting for inspection” of the cell MA in the damage actual condition matrix table M11 in FIG. 19 indicates that the inspection of the damaged form (runout) of the part (coupling) has not been performed. Since this unexecuted state value is prioritized over the abnormal level, the part evaluation result M11a as the coupling that is the part and the part evaluation result M11c as the axle are also displayed as “waiting for inspection”. In this way, by introducing the work state value into the damage actual condition matrix table, it is possible to configure a screen that prompts the execution of the inspection item “coupling vibration measurement”.
[0112]
FIG. 20 is a configuration diagram of an equipment management system showing a second embodiment of the present invention.
[0113]
In FIG. 20, the same reference numerals as those in FIG. 5 showing the first embodiment denote the same or corresponding parts, and the description of the overlapping parts is omitted.
[0114]
In FIG. 20, in the cell processing unit 31A of the facility management system 100A, a cell treatment method determination unit 13 is additionally provided in the cell processing unit 31 of the first embodiment. In the site processing unit 32A, the site treatment determining unit 16 is additionally provided in the site processing unit 32 of the first embodiment. In the component processing unit 33A, a component treatment method determination unit 19 is additionally provided in the component processing unit 33 of the first embodiment. Furthermore, the facility management system 100A additionally includes a treatment method output unit 39.
[0115]
Here, the cell treatment method determination unit 13 takes in the result of the evaluation determination from the cell determination result output unit 3, refers to the treatment method determination table described after the treatment method is defined and stored in advance, and corresponds to each corresponding evaluation target. The treatment method is determined and the treatment method information is output.
[0116]
The part treatment method determination unit 16 takes in the result of the comprehensive evaluation determination from the part determination result output unit 6 and refers to a later-described treatment method determination table in which a treatment method is defined and stored in advance, and the corresponding comprehensive evaluation determination target treatment method And the treatment method information is output.
[0117]
The component treatment method determination unit 19 takes in the result of the higher evaluation determination from the component determination result output unit 9, refers to a later-described treatment method determination table that defines and stores the treatment method in advance, and corresponds to the corresponding higher evaluation determination target treatment method And the treatment method information is output.
[0118]
FIG. 21 shows a damage actual condition matrix table M12 used in the second embodiment, and this damage actual condition matrix table M12 is obtained by adding a column of site treatment method M12a to the damage actual condition matrix table M4 of FIG. .
[0119]
FIG. 22 shows a treatment method determination table 12 used for determining a treatment method. The treatment method determination table 12 is for each part of the damage actual state matrix table M12, and the management target registered in the part. There are as many sheets as the number of damage forms (in FIG. 22, 12 (1), 12 (2),..., 12 (n) n sheets).
[0120]
The function of the treatment method determination table 12 will be described using the treatment method determination table 12 (1) shown in FIG.
[0121]
The treatment method determination table 12 (1) includes a damage level 12c that is a classification in which the damage form 1 is set in advance, a treatment method 12d that is determined in accordance with the damage level, and an actual damage transmitted from the cell determination result output unit 3. The storage cell 12a of the damage degree judgment value f real as the actual state of the form, and the damage level 12c (fa set in advance corresponding to the damage degree judgment value f real and the treatment method 12d ₁₁ , Fa ₁₂ ... fa ₁₅ The damage level adjustment logic 12b for adjusting the relationship with “)”.
[0122]
The combination of the damage level 12c and the treatment method 12d is, for example, the lightest damage level fa as a treatment method. ₁₁ Treatment method Sa corresponding to ₁₁ Is usually Sa ₁₁ : Use as is with minimal care. Conversely, the most severe damage level fa ₁₅ Treatment method Sa corresponding to ₁₅ Sa ₁₅ : New part replacement of part A is defined.
[0123]
In this way, the damage level classification (fa ₁₁ , Fa ₁₂ ... fa ₁₅ ) And the treatment method 12d may not correspond appropriately depending on the system. In this case, the damage level adjustment logic 12b is adjusted.
[0124]
In the example of FIG. 22, when the damage degree evaluation classification used by the facility management system 100A is, for example, “normal”, “caution”, “abnormal”, the damage level adjustment logic 12b of the treatment method determination table 12 (1). Then, "Caution" is fa ₁₁ And fa ₁₂ And "abnormal" is fa ₁₃ And fa ₁₄ And fa ₁₅ As an OR condition.
[0125]
For example, “Caution” is set to fa ₁₁ Or fa ₁₂ The OR condition such as the above may be displayed as a parallel selection of the corresponding treatment method as it is as a selection item by the system user, or the treatment method is automatically selected according to the damage degree judgment value f real as the actual state of the damage form This is to make it possible.
[0126]
The cell treatment method determination unit 13 transmits to the treatment method output unit 39 treatment method candidates according to the degree of damage of each damage form belonging to the site determined using the treatment method determination table 12.
[0127]
The treatment method output unit 39, for example, when a corresponding cell such as a region-by-region display cell of the region treatment method display M12a on the damage actual state matrix table M12 in FIG. 21; M12b to M12g. To display the treatment method for the corresponding part. For example, the contents of B1a in the part processing display example B1 in FIG. 23 are displayed corresponding to the cell M12b that also displays the treatment method for each part in FIG. Further, the content of B1b in FIG. 23 is displayed correspondingly to the treatment method display cell M12c for each part in FIG.
[0128]
The site treatment method determination unit 16 collects cell treatment methods as they are and summarizes the treatment methods for the entire site as a list. When the site treatment method display M12a in FIG. 21 is clicked, for example, the site treatment method list shown in FIG. The part treatment method output position information is output to the treatment method output unit 39 and displayed in a separate window.
[0129]
FIG. 23 shows, in parallel, treatment methods corresponding to the degree of damage for all damage modes other than “normal” in FIG. Each row in FIG. 23 is a treatment method corresponding to each cell. When this is viewed in units of parts, it becomes a part treatment method. For example, with respect to the part “body trunk”, since the damage form “runout” and “scratch” are two evaluation targets, in FIG. 23, the cell B1a indicating the treatment method is arranged in parallel with each damage form. It is displayed. The site treatment methods M12d and M12e in FIG. 21 are not displayed in FIG. 23 because the evaluation result is “normal”.
[0130]
Further, the system user can review the contents displayed in this window as appropriate (exclude inappropriate treatment methods or consolidate them, etc.), re-register them as new treatment methods, and register them as site treatment methods. The site treatment method determination unit 16 gives priority to the correction contents by the system user. For example, treatments for two damage forms (swings and scratches) on the “body trunk” of FIG. 23 can be combined as in the example of the component treatment method display example B2 shown in FIG.
[0131]
Next, the part treatment method determination unit 19 receives the treatment methods for each part determined by the part treatment method determination unit 16, collects them as they are, and collects them as a treatment method list for the entire part. Further, when the part treatment method display M12h in FIG. 21 is clicked, for example, the part treatment method display example B2 in FIG. 24 and the output position information of the part treatment method are output to the treatment method output unit 39 and displayed in another window. To do.
[0132]
Here, FIG. 24 is a display example corresponding to the cell M12h of the component treatment method display of FIG. 21, and is a conversion example of the part level treatment method of FIG. 23 to the component treatment method.
This is an example in which items related to each other in the matrix table of the part treatment method list of FIG. 23 are displayed by the system user in an aggregated manner. The treatment method B1a and the treatment method B1c of FIG. B2a is created, and similarly, the treatment method B1b and the treatment method B1d of FIG. 23 are integrated to create the treatment method B2b of FIG.
[0133]
Therefore, when the component treatment method is automatically output by the system, the cell treatment method list for the component is output as shown in FIG. 23. However, like the part treatment method decision unit 16, the component treatment method decision unit By providing the system user with an editing function 19 as well, it is possible to output an integrated treatment method as shown in FIG.
[0134]
Next, a modification of the second embodiment of the present invention will be described with reference to FIGS.
[0135]
In this example, the treatment methods in units of parts defined by the part treatment method determination unit 16 in FIG. 20 are aggregated as treatment methods as devices in accordance with the relationship between the devices and the components that are constituent elements thereof. In the same way, the treatment methods at the next lower hierarchical level are integrated together between the layers of the equipment system of equipment and device, and the facility actual condition summary table is developed in the explanation of FIGS. 14 to 15B. In the same way as that, it is possible to expand the subordinates.
[0136]
First, the damage actual state matrix table M12 in FIG. 21 is obtained at the part level shown in FIG. 25 by the same processing as the damage actual state matrix table M4 in FIG. 10 converted into the facility actual state summary table M6 in FIG. It converts into the equipment actual condition summary table M13.
[0137]
The facility actual condition summary table M13 of FIG. 25 adds a part treatment method display cell M13c to the part evaluation result display cell M13b corresponding to the part evaluation result display cell M6b to the facility actual condition summary table M6 of FIG. A component treatment method display cell M13e is added to the component evaluation result display cell M13d corresponding to the cell M6a. When an arbitrary part corresponding portion of the part evaluation result display cell M13b is selected, another window is called, and the treatment method for the corresponding part is selected and displayed from the treatment methods shown in FIG. Similarly, when the component treatment method display cell M13e is selected, the component treatment method of FIG. 24 is displayed.
[0138]
The facility actual condition summary table M13 in FIG. 25 has a configuration in which the part treatment method display cell M13c and the part treatment method display cell M13e are added to the facility actual condition summary table M6 in FIG. Can also be consolidated at the top. Therefore, corresponding to FIGS. 15A and 15B, the equipment level facility actuality summary table M14 of FIG. 26 and the facility actuality summary table M15 of FIG. 27 can be obtained.
[0139]
On the contrary, it is possible to subordinate to the equipment actual situation summary table M14 in FIG. 26 from the equipment actual situation summary table M15 in FIG. 27 and the equipment actual situation summary table M13 in FIG. Inverse conversion to Table M12 is also possible.
[0140]
For the higher level aggregation of such treatment methods, the conversion method from FIG. 23 to FIG. In the process of conversion, the treatment method list becomes larger as it goes up the equipment system unless corrections are made in the human system, but the facility summary tables M13 to M15 are equipped with only a function for calling these lists. Therefore, it does not hinder these higher level aggregation operations.
[0141]
Such treatment methods are determined from the lower level of the device system, and are determined step by step for each level while performing higher level integration toward the upper level of the device system. Each level can be displayed step by step.
[0142]
In addition, by arbitrarily performing such high-level aggregate display or low-level expansion display, the treatment method corresponding to the facility or equipment at that level is called from the equipment actuality summary table at any level of the equipment system, and matrix expansion display is performed. Therefore, it is possible to efficiently obtain information at a level required by the system user.
[0143]
Next, a third embodiment of the present invention will be described with reference to FIGS.
[0144]
In the third embodiment, in the damage form matrix table of the first embodiment, a management method of the damage form is provided at the intersection (cell in the matrix table) between the part to be managed and the damage form corresponding to the part. A “management form matrix table” containing the management form names to be displayed is displayed, and this management state display is performed by display such as color coding.
[0145]
The facility management system according to the present invention starts from the damage form matrix table M2 shown in FIG. 6 as a result of the observation of the machine parts, and the damage actual condition matrix table M4 in FIG. 10 for clarifying the actual damage status of the machine parts. Alternatively, the damage actuality matrix table M12 shown in FIG. 21 is basically derived. However, when this is developed for a thermal power plant, special conditions as described below in the field should be taken into consideration. Therefore, it can be made easier to use.
[0146]
A series of management methods, from discovery methods to follow-up surveys and implementation of countermeasures, regarding various types of damage that can occur in various equipment, parts, and parts subordinate to each facility constituting a thermal power plant It is known that several patterns are established. FIG. 28 is a management state definition table C1 in which the patterns are classified and defined as management forms. Almost all forms of damage found in thermal power plants are organized in this category.
[0147]
When the management form definition table C1 shown in FIG. 28 is applied to each damage form in the damage actual state matrix table M4 in FIG. 10, the * mark is replaced with the management form name according to the actual management method of each damage form. Further, by adding a part treatment method display cell and a part treatment method display cell, a management form matrix table M16 as shown in FIG. 29 having the same format as the damage actual state matrix table M12 shown in FIG. can get.
[0148]
This management form matrix table M16 also becomes a matrix table showing a management method of damage forms that can occur in each part, knows the management form to be applied for the inspection of the damage forms, and the work to be performed It becomes possible to know up to the outline.
[0149]
In addition, it should be noted that not all management forms displayed in the management form matrix table M16 are necessarily implemented in every periodic inspection. For example, the “remaining life” defined in FIG. 28 is usually carried out with a long cycle of about 10 years, and the management form is skipped when an arbitrary periodic inspection is considered. It is possible that In such a case, it is desirable to invalidate (do not operate even if selected) the cell in the management form. This means that the management form matrix table M16 can also be used for management of inspection work to be performed in the periodic inspection, and various uses are conceivable.
[0150]
In order for the management form matrix table M16 to have the function of the damage actual condition matrix table M12 of FIG. 21, the damage actual condition in the damage actual condition matrix table M12 is evaluated by the character expressions “normal”, “caution”, and “abnormal”. Instead of the level, for example, the display of the management form name is left as it is, and each is displayed in a color display such as green, yellow and red. In this way, if the management form matrix table with color indication of damage level is newly implemented in the same manner as the damage actual condition matrix table, conversion to the equipment actual condition summary table, etc. will be performed instead of the abnormal evaluation level display. It can be generated as it is by using the display, and can be summarized and implemented in the same manner as in the first and second embodiments.
