【0009】
次に、この変電機器監視診断システムの動作について説明する。監視対象となる変電機器に故障・劣化等による異常が発生した場合、その現象は機器表面温度の上昇,ガス圧・空気圧・油圧の低下、制御電流の電流値や通電時間の変化として現れ、機器に取り付けられたセンサー(4)によって検出される。センサー(4)からの微弱信号はセンサー(4)の近傍に設置された信号変換器(5)により4〜20mAのアナログ信号に変換され、データ収集手段(6)によって一定周期で取り込まれる。データ処理手段(7)では、取り込まれたセンサー信号と予め設定された機器毎の異常判定レベルとの比較により異常を検出し、センサー信号と判定結果とを記憶装置(8)、マンマシンインターフェイス(I/F)(9)、及び伝送インターフェイス(I/F)(10)にそれぞれ出力する。設備診断データ記憶装置(8)では、前記情報を受けて、センサー信号をトレンドデータとして、また判定結果を異常履歴データとして蓄積する。変電所内のマンマシンインターフェイス(I/F)(9)では、保守員の要求に応じて、データ処理手段(7)からの最新の情報、設備診断データ記憶装置(8)からのトレンドデータ・異常履歴データ、または伝送インターフェイス(I/F)(10)を経由して上位系からのガイダンスデータを表示する。各変電所の変電所監視装置(1)からのセンサー信号と判定結果は、双方向伝送路(3)から上位系監視装置(2)内の伝送インターフェイス(I/F)(11)を経由して表示情報検索手段(12)に入力される。表示情報検索手段(12)では、変電所からの情報に基づいて、各機器の異常状態の把握やその原因特定、及び復旧支援のためのガイダンス情報をガイダンスデータ記憶装置(13)から抽出し、上位系のマンマシンインターフェイス(I/F)(14)と伝送インターフェイス(I/F)(11)に出力する。更に各変電所からのセンサー信号は、設備診断データのバックアップとして全変電所トレンドデータ記憶装置(14)に蓄積される。伝送インターフェイス(I/F)(11)に出力されたガイダンスデータは双方向伝送路(3)を経由して変電所に伝送される。マンマシンインターフェイス(I/F)(15)では、操作員の要求に応じて、表示情報検索手段(12)からのガイダンスデータをはじめ、トレンドデータ記憶装置(14)から各変電所における機器の状態や履歴を一括して表示することができる。

【0012】
実施の形態3.
実施の形態1は、変電機器の故障・劣化等による異常が検出された後の対応、すなわち事後保全を対象としているが、例えば図3のように、上位系監視装置(2)が、全変電所トレンドデータ記憶装置(14)に蓄積された情報と数学的手法に基づいて、異常レベルに達するまでの期間を判定する異常到達予測手段(31)と、予め異常回避のために必要な保守支援データを蓄積した記憶装置(32)とを備えることにより、異常が検出される前の予測保全が可能となる。
【0013】
実施の形態4.
実施の形態1は、予め設定された一定の計測周期により取り込まれたデータを対象といているが、例えば図4のように、変電所監視装置(1)が強制計測手段(41)を備えることにより、変電所内のマンマシンインターフェイス(I/F)(9)、または上位系のマンマシンインターフェイス(I/F)(15)からの入力、すなわち変電所・対象機器・監視項目の設定により、通常の計測周期とは異なったリアルタイムな監視診断を必要に応じて実行することができる。
