Description

本発明は、配電系統を監視制御する配電系統操作装置に関する。   The present invention relates to a power distribution system operating device that monitors and controls a power distribution system.

配電系統操作装置の最も重要な目的に、配電線の事故発生時に事故区間を検出し、負荷側の停電区間（負荷側健全区間）に対して他の配電線から負荷融通を行う事故復旧操作がある。この事故復旧操作については、非特許文献１あるいは２に概要は紹介されているが、以下図面を参照して説明する。   The most important purpose of the power distribution system operation device is to perform an accident recovery operation that detects an accident section when a distribution line accident occurs and performs load accommodation from another distribution line for the load-side power outage section (load-side healthy section). is there. This accident recovery operation is introduced in Non-Patent Document 1 or 2, but will be described below with reference to the drawings.

図５は、従来の配電系統操作装置の動作を説明するブロック図である。
図５において、ＦＣＢ１およびＦＣＢ２は変電所ＤＳＳに設置されて、それぞれ配電線Ｆ１、Ｆ２を引き出すための配電線引出し用遮断器（以下、配電線遮断器という）であり、通常は「入」の状態にある。配電線Ｆ１は通常「入」状態にある開閉器Ｓ１、Ｓ２、Ｓ３およびＳ４により配電区間１−１、１−２、１−３、１−４および１−５に区分されている。なお、以下の説明では、配電区間を単に「区間」と呼び、また、配電線遮断器と、この配電線遮断器を介して変電所から引き出された配電線と、この配電線を適宜な区間に区分する開閉器とからなる系統を配電系統と呼ぶ。 FIG. 5 is a block diagram for explaining the operation of a conventional power distribution system operating device.
In FIG. 5, FCB1 and FCB2 are installed in the substation DSS, and are distribution line drawing circuit breakers (hereinafter referred to as distribution line circuit breakers) for drawing out the distribution lines F1 and F2, respectively. Is in a state. The distribution line F1 is divided into distribution sections 1-1, 1-2, 1-3, 1-4, and 1-5 by switches S1, S2, S3, and S4 that are normally in an “on” state. In the following description, the distribution section is simply referred to as “section”, and the distribution line breaker, the distribution line drawn from the substation via the distribution line breaker, and the distribution line as an appropriate section. A system composed of switches classified into two is called a power distribution system.

配電線Ｆ１と同様に、配電線Ｆ２も通常「入」状態の開閉器Ｓ１１、Ｓ１０およびＳ１２により区間２−１、２−２、２−３および２−４に区分されている。区間１−２は通常「切」状態の開閉器Ｓ５を介して配電線Ｆ３に接続されており、以下同様に区間１−３は通常「切」状態の開閉器Ｓ６により配電線Ｆ４に、区間１−４は通常「切」状態の開閉器Ｓ７およびＳ８により配電線Ｆ５およびＦ６に、区間１−５は開閉器Ｓ９により配電線Ｆ２に、区間２−４は開閉器Ｓ１３により配電線Ｆ７にそれぞれ接続されている。   Similar to the distribution line F1, the distribution line F2 is also divided into sections 2-1, 2-2, 2-3 and 2-4 by the switches S11, S10 and S12 which are normally in the “on” state. The section 1-2 is normally connected to the distribution line F3 via the switch S5 in the “OFF” state. Similarly, the section 1-3 is connected to the distribution line F4 by the switch S6 in the normal “OFF” state. 1-4 is normally switched to the distribution lines F5 and F6 by the switches S7 and S8, the section 1-5 is to the distribution line F2 by the switch S9, and the section 2-4 is to the distribution line F7 by the switch S13. Each is connected.

各開閉器Ｓ１〜Ｓ１３には各区間の電源側配電線および負荷側配電線をそれぞれ制御電源とする開閉器遠方監視制御子局Ｃ１〜Ｃ１３が取り付けられている。そして、これら開閉器遠方監視制御子局Ｃ１〜Ｃ１３は、通信路Ｌを介して変電所ＤＳＳ内に設けられた変電所監視制御子局Ｃｄ、遠方監視制御親局２を経て配電系統操作装置１に接続されており、配電線が充電されているとき、すなわち制御電源が活きているとき、開閉器の状態情報を配電系統操作装置１に通知するとともに、配電系統操作装置１からの操作指令を受信するように構成されていれている。 The switches S1 to S13 are equipped with switch remote monitoring control slave stations C1 to C13 that use the power-side distribution line and the load-side distribution line in each section as control power sources, respectively. The switch remote monitoring control slave stations C1 to C13 are connected to the distribution system operating device 1 via the communication path L via the substation monitoring control slave station Cd and the remote monitoring control master station 2 provided in the substation DSS. When the distribution line is charged, that is, when the control power supply is active, the state information of the switch is notified to the distribution system operation device 1 and the operation command from the distribution system operation device 1 is sent. It is configured to receive.

なお、配電系統操作装置１は、開閉器遠方監視制御子局Ｃ１〜Ｃ１３を監視制御するだけでなく、変電所ＤＳＳ内に設置されている遮断器ＦＣＢ１、ＦＣＢ２、・・・や図示していない保護リレーの状態、配電線の負荷電流や電圧が監視・計測可能なようになっている。 The distribution system operating device 1 not only monitors and controls the switch remote monitoring control slave stations C1 to C13 , but also does not show the circuit breakers FCB1, FCB2,... Installed in the substation DSS. The status of protection relays, distribution line load current and voltage can be monitored and measured.

図６は配電線Ｆ１の区間１−３に事故が発生した場合の配電線遮断器ＦＣＢ１および配電線Ｆ１に設置された開閉器Ｓ１〜Ｓ４の動作を示すタイムチャートである。   FIG. 6 is a time chart showing the operation of the distribution line breaker FCB1 and the switches S1 to S4 installed in the distribution line F1 when an accident occurs in the section 1-3 of the distribution line F1.

今ここで、区間１−３に事故が発生したとすると、配電線遮断器ＦＣＢ１は初回の事故遮断（タイムチャートの［ｉ］の時点）から例えば３０秒後に再閉路し（タイムチャートの［ii］の時点）、区間１−１が充電されると開閉器Ｓ１が時限順送機能により投入される。   Now, assuming that an accident occurs in the section 1-3, the distribution line breaker FCB1 is reclosed, for example, 30 seconds after the first accident interruption (time point [i] in the time chart) ([ii] in the time chart). ], When the section 1-1 is charged, the switch S1 is turned on by the timed sequential feeding function.

開閉器Ｓ１の投入により区間１−２が充電されると、次に開閉器Ｓ２が同様に時限順送機能により投入される。ここで、区間１−３に事故があったとすると、開閉器Ｓ２の投入と共に事故電流が流れ、変電所ＤＳＳ内の保護リレーにより再度事故を検出し、配電線遮断器ＦＣＢ１を再遮断する（タイムチャートの［iii］の時点）。   When the section 1-2 is charged by turning on the switch S1, the switch S2 is then turned on by the timed sequential feed function. Here, if there is an accident in the section 1-3, the accident current flows as the switch S2 is turned on, the accident is detected again by the protective relay in the substation DSS, and the distribution circuit breaker FCB1 is shut off again (time) [Iii] on the chart).

このとき、電源側の開閉器Ｓ２は事故点投入を検出して投入ロック状態となる。さらに配電線遮断器ＦＣＢ１は、例えば６０秒後に再々閉路し（［iv］の時点）、区間１−１が充電されると開閉器Ｓ１が時限順送機能により投入され、区間１−２が充電される。区間１−２が充電されても開閉器Ｓ２は上述のように投入ロックされているので投入されない。これら一連の動作にかかる時間は電力会社の運用により差異はあるが、通常上述したように、遮断器の初回遮断から再閉路までが３０秒、再遮断から再々閉路までが６０秒、さらに開閉器の時限投入時間がかかることから、事故発生に伴う遮断器の初回遮断から再々閉路までおよそ９０秒＋αを要する。   At this time, the switch S2 on the power source side detects the accident point input and enters the input lock state. Further, the distribution circuit breaker FCB1 is closed again after 60 seconds, for example (at the time of [iv]), and when the section 1-1 is charged, the switch S1 is turned on by the timed progressive function, and the section 1-2 is charged. Is done. Even if the section 1-2 is charged, the switch S2 is not turned on because it is turned on and locked as described above. Although the time required for these series of operations varies depending on the operation of the electric power company, normally, as described above, the circuit breaker from the first interruption to the reclosing is 30 seconds, the reinterruption to the reclosing circuit is 60 seconds, and the switch Therefore, it takes about 90 seconds + α from the first interruption of the circuit breaker due to the occurrence of the accident to the re-closing.

配電系統操作装置１では、これら遮断器や開閉器の一連の動作を監視しており、再々閉路後（タイムチャートの［ｖ］の時点）に通信路Ｌを介して開閉器Ｓ２が「切」状態で投入ロックを確認した上で、事故区間を１−３と判定し、事故区間より負荷側の健全停電区間１−４、１−５に対する融通送電手順を作成し、作成された融通送電手順に従って開閉器を遠方操作し、融通送電する。図５の例では、例えば区間１−５は開閉器Ｓ９を投入、区間１−４は開閉器Ｓ７を投入のような融通送電手順が作成される。   The distribution system operating device 1 monitors a series of operations of these circuit breakers and switches, and the switch S2 is “turned off” via the communication path L after closing again (at time [v] in the time chart). After confirming the input lock in the state, the accident section is determined to be 1-3, and the interchange transmission procedure for the healthy power failure sections 1-4 and 1-5 on the load side from the accident section is created. Operate the switch remotely according to In the example of FIG. 5, for example, an interchange power transmission procedure is created in which the switch S9 is turned on in the section 1-5 and the switch S7 is turned on in the section 1-4.

配電系統操作装置１が被融通区間への融通送電を行うための融通計算処理に関し、どの連係配電線から融通送電するかの融通ルート決定の条件としては、（ａ）過負荷が発生しないこと、（ｂ）良質な電気（融通送電後の電圧降下量が許容値内）が融通できること、（ｃ）融通送電後の配電線予備力が残ること、などを計算パラメータとして考慮して計算する。   With regard to the flexible calculation process for the power distribution system operating device 1 to perform flexible power transmission to the flexible section, as a condition for determining the flexible route from which linked distribution lines to be interchanged and transmitted, (a) that no overload occurs, (B) Calculations are made taking into account, as calculation parameters, good quality electricity (the amount of voltage drop after interchange transmission is within an allowable value) and (c) the distribution line reserve after interchange transmission remains.

そのためには、配電系統全ての配電線の予備力を算出し、その予備力と配電系統上の開閉器の組合せの中から、未送電区間を最小にするような組合せを見つけ、その組合せに基づいて融通送電手順を作成する。配電系統が大きく、また複雑になるにつれて、配電系統上の配電線、開閉器の数が増えるために、その組合せの数も膨大となり、融通計算処理にも時間がかかる。   To do so, calculate the reserve capacity of all distribution lines in the distribution system, find a combination that minimizes the unsent section from the combination of the reserve capacity and the switch on the distribution system, and based on that combination To create a flexible transmission procedure. As the power distribution system becomes larger and more complicated, the number of distribution lines and switches on the power distribution system increases, so the number of combinations becomes enormous, and it takes time for the flexible calculation processing.

従来では、融通計算処理は対象系統の規模にもよるが、数秒から数十秒あるいは数分かかることもある。このため、事故発生から再々閉路までがおよそ９０秒＋α、さらにそこから融通送電手順作成を行った後に、作成された融通送電手順に従って配電系統の開閉器を操作し融通送電することから、実際の健全停電区間への送電操作完了までには非常に時間がかかっていた。   Conventionally, the flexible calculation processing may take several seconds to several tens of seconds or several minutes depending on the scale of the target system. For this reason, from the occurrence of the accident to the re-closing cycle is approximately 90 seconds + α, and after creating the interchange transmission procedure from there, the switch of the distribution system is operated according to the created interchange transmission procedure, and the interchange transmission is performed. It took a very long time to complete the power transmission operation to the healthy power outage section.

図５では比較的簡単な配電系統であるが、区間１−４への融通送電対象配電線はＦ５とＦ６となり、どちらから送電するかは上述した融通計算パラメータを考慮して計算され決定される。また、区間１−５に開閉器Ｓ９を投入して配電線Ｆ２から融通送電しようとしたが、区間１−５に融通送電すると配電線Ｆ２が過負荷になるようなケースもある。このようなケースでは、例えば、開閉器Ｓ１２を開放して開閉器Ｓ１３を投入して区間２−４を配電線Ｆ７から送電し、配電線Ｆ２の負荷を軽くしてから開閉器Ｓ９を投入する融通送電手順も考えられる。このように、融通計算処理は対象系統の大きさや負荷の状況によって、その処理時間がかかることになる。   In FIG. 5, although the distribution system is relatively simple, the distribution transmission target distribution lines to the section 1-4 are F5 and F6, and from which the transmission is performed is calculated and determined in consideration of the above-described interchange calculation parameters. . In addition, the switch S9 is inserted into the section 1-5 to try to accommodate and transmit power from the distribution line F2, but there is a case where the distribution line F2 is overloaded when the interchanged power is transmitted to the section 1-5. In such a case, for example, the switch S12 is opened, the switch S13 is turned on, the section 2-4 is transmitted from the distribution line F7, the load on the distribution line F2 is lightened, and then the switch S9 is turned on. A flexible transmission procedure is also conceivable. As described above, the flexible calculation processing takes a processing time depending on the size of the target system and the load status.

また、次に配電用変電所ＤＳＳの配電用変圧器ＴＲの事故（以下、バンク事故という）のような大規模事故を考えてみると、配電用変電所ＤＳＳのバンクからは一般的には複数の配電線が引き出されている関係でバンク事故の場合の停電範囲は広範なものとなり、他の配電線からの融通送電対象区間は膨大で、その融通送電手順作成のための融通計算処理もおのずと時間がかかることになる。   Next, when considering a large-scale accident such as an accident in the distribution transformer TR of the distribution substation DSS (hereinafter referred to as a bank accident), there are generally several from the banks of the distribution substation DSS. In the case of a bank accident, the power outage range in the case of a banking accident is wide, and the interchangeable transmission target section from other distribution lines is enormous, and the interchange calculation processing for creating the interchangeable transmission procedure is also natural. It will take time.

バンク事故時には一般的に、事故発生後すぐには配電線側での融通送電操作は行わず、上位系統側での融通や、同一変電所他バンクからの送電を待って、それが不可であればオペレータの指示によって配電線側での融通送電操作手順を作成し、融通送電操作を行うようにしている。   Generally, at the time of a bank accident, the power transmission operation on the distribution line side is not performed immediately after the accident occurs, and it is impossible to wait for the power transmission on the higher system side or power transmission from other banks in the same substation. For example, a flexible power transmission operation procedure on the distribution line side is created according to an instruction from the operator, and the flexible power transmission operation is performed.

このように、従来の技術では配電線に事故が発生してから再々閉路までの時間が９０秒＋αかかり、さらにその時点から融通送電手順を作成し操作するため、融通操作完了までは数分の時間がかかることがあった。また、変電所バンク事故においても、配電線側での融通送電操作が必要と判断されてから融通送電手順を作成していたため、配電系統の規模によっては融通操作完了まで多大な時間を要することがあった。   In this way, in the conventional technology, it takes 90 seconds + α from the occurrence of an accident to the distribution line until the re-closing time, and since the interchange power transmission procedure is created and operated from that time, it takes several minutes until the interchange operation is completed. It sometimes took time. In addition, even in a substation bank accident, since the interchange transmission procedure was created after it was determined that the interchange transmission operation on the distribution line side was necessary, depending on the size of the distribution system, it could take a long time to complete the interchange operation. there were.

なお、配電線事故時の融通送電の計算時間を短縮する発明として、次の特許文献１、２に記載の発明が開示されている。   In addition, the invention of the following patent documents 1 and 2 is disclosed as invention which shortens the calculation time of the flexible power transmission at the time of a distribution line accident.

特許文献１に記載の発明は、配電系統事故発生時にリアルタイムに配電系統切り替えを行うものではあるが、配電系統切り替えのための負荷融通計算に際して、全ての融通組合せを作成するのではなく、複数の融通手順解の候補を作成し、これを評価関数で評価することによって負荷融通計算そのものを早くしようとする方法である。   Although the invention described in Patent Document 1 performs distribution system switching in real time when a distribution system fault occurs, it does not create all accommodation combinations when calculating load accommodation for distribution system switching. In this method, candidates for the accommodation procedure solution are created and evaluated by an evaluation function to speed up the load accommodation calculation itself.

特許文献２に記載の発明は、基本的に融通計算そのものを早くする方法に関するもので、配電線の区間負荷などの負荷融通計算に必要な一部のデータ（季節、日変化、週変化に応じた負荷データ）を予め計算して保存しておき、これを初期値として事故発生時にその時の負荷状態に合わせて再計算するようにしている。事故発生時に計算された条件（季節や曜日、時間などに対応する負荷データ）と合致するものがあれば、即座に負荷融通計算を実行するものである。

Load data) is calculated and stored in advance, and this is used as an initial value to be recalculated according to the load state at the time of the accident. If there is something that matches the conditions (load data corresponding to the season, day of the week, time, etc.) calculated at the time of the accident, the load interchange calculation is executed immediately.

特許文献１に記載の発明の場合、複数の融通手順解の候補を作成し、これを評価関数で評価することによって負荷融通計算そのものを早くしようとする方法であるが、この計算はあくまでも背景技術で述べたように、配電線に事故が発生してから再々閉路までの時間（９０秒＋α）を待って、事故区間が判明して初めて計算を開始するものであり、負荷融通計算が短時間で行えると言っても、数十秒〜数分はかかる欠点がある。   In the case of the invention described in Patent Document 1, it is a method of creating a plurality of candidates for the accommodation procedure solution and evaluating it with an evaluation function so as to speed up the load accommodation calculation itself. As described in, the calculation is started only after the time between the occurrence of an accident on the distribution line and the re-closing cycle (90 seconds + α), after the accident section is found, and the load interchange calculation is short. Even if it can be done, there is a drawback that it takes several tens of seconds to several minutes.

また、特許文献２に記載の発明の場合、事故発生時に計算された条件（季節や曜日、時間などに対応する負荷データ）と合致するものがあれば、即座に負荷融通計算を実行するものであるが、一般的にその条件は様々であり、条件と合致するデータはほとんど無いのが現実的であり、せっかく予め負荷融通計算に必要なデータを作成しておいても結局は都度再計算することになるという欠点がある。   Further, in the case of the invention described in Patent Document 2, if there is anything that matches the conditions (load data corresponding to the season, day of the week, time, etc.) calculated at the time of the accident, the load accommodation calculation is executed immediately. Although there are generally various conditions, it is realistic that there is almost no data that matches the conditions. Even if data necessary for load accommodation calculation is created in advance, it will be recalculated each time after all. There is a drawback that it will be.

そこで本発明は、上記従来技術の課題を解決するためになされたものであり、配電線事故あるいはバンク事故時に、融通送電時間を減少させ、事故による電力供給支障を高速に解決することのできる配電系統操作装置を提供することを目的とするものである。   Accordingly, the present invention has been made to solve the above-described problems of the prior art, and in the event of a distribution line accident or bank accident, distribution power transmission time can be reduced, and power distribution trouble due to the accident can be solved at high speed.

In addition, the same code | symbol is attached | subjected to the part which is common throughout each figure, and the overlapping description is abbreviate | omitted suitably.

（第１の実施形態）
まず、図１を参照して本発明に係わる配電系統操作装置の第１の実施形態について説明する。
図１は、本発明の第１の実施形態に配電系統操作装置の構成を示すブロック図である。 (First embodiment)
First, a first embodiment of a power distribution system operating device according to the present invention will be described with reference to FIG.
FIG. 1 is a block diagram showing a configuration of a power distribution system operating device according to the first embodiment of the present invention.

図１において、１Ａは本実施形態による配電系統操作装置であり、例えばディジタル計算機によって構成され、ディジタル計算機のハードウェアおよびソフトウェアを用いることによって次の機能手段１０１〜１０５を実現することができるようになっている。   In FIG. 1, reference numeral 1A denotes a power distribution system operating device according to the present embodiment, which is composed of, for example, a digital computer so that the following functional means 101 to 105 can be realized by using hardware and software of the digital computer. It has become.

すなわち、配電系統操作装置１Ａは、開閉器遠方監視制御子局Ｃ１〜Ｃ１３、変電所監視制御子局Ｃｄからの情報を後述する遠方監視制御親局２を経て取り込むことにより、配電系統状態を常時監視する監視手段１０１と、この監視手段１０１により検出された電力供給支障事故発生時に、記憶装置３に記憶された「系統データ３０１」をもとに想定される全融通区間候補に対して融通送電手順１０４を作成する融通送電手順作成手段１０２と、この融通送電手順作成手段１０２により作成された融通送電手順１０４を記憶装置３に記憶させる融通送電手順記憶手段１０３と、前記監視手段１０１により検出された配電線事故区間情報に基づいて前記記憶装置３に記憶された融通送電手順１０４の中から最適な融通送電手順を取り出して開閉器遠方監視制御子局に制御指令を出力する制御手段１０５とから構成されている。   That is, the power distribution system operating device 1A always captures the state of the power distribution system by taking in information from the switch remote monitoring control slave stations C1 to C13 and the substation monitoring control slave station Cd via the remote monitoring control master station 2 described later. The monitoring means 101 to be monitored and the flexible power transmission to all the possible interchange section candidates assumed based on the “system data 301” stored in the storage device 3 when the power supply trouble detected by the monitoring means 101 occurs. Detected by the flexible power transmission procedure creating means 102 for creating the procedure 104, the flexible power transmission procedure storage means 103 for storing the flexible power transmission procedure 104 created by the flexible power transmission procedure creating means 102 in the storage device 3, and the monitoring means 101. Based on the distribution line fault section information obtained, the optimum flexible power transmission procedure is extracted from the flexible power transmission procedure 104 stored in the storage device 3 and opened and closed. And a control unit 105 for outputting a control command to the remote monitor control slave station.

ここで、系統データ３０１とは、配電系統を構成する設備の機器種別、接続情報等の設備データと、遠方監視制御親局２を経由して入力された事故発生直前の区間負荷、配電線電流値、開閉器「入」／「切」状態等の系統状態データと、から構成されているデータをいう。   Here, the system data 301 is equipment data such as the type of equipment constituting the power distribution system, connection information, the section load immediately before the occurrence of the accident, the distribution line current input via the remote monitoring control master station 2 This is data composed of value and system state data such as the switch “ON” / “OFF” state.

前記遠方監視制御親局２は、通信路Ｌによって変電所監視制御子局Ｃｄや、配電系統に設置された開閉器Ｓ１〜Ｓ１３に取り付けられた開閉器遠方監視制御子局Ｃ１〜Ｃ１３と接続され、開閉器Ｓ１〜Ｓ１３の遠方監視制御や変電所内機器の常時監視を行うことが可能になっている。   The remote monitoring control master station 2 is connected to the substation monitoring control slave station Cd and the switch remote monitoring control slave stations C1 to C13 attached to the switches S1 to S13 installed in the distribution system through the communication path L. The remote monitoring control of the switches S1 to S13 and the constant monitoring of the devices in the substation can be performed.

また、ＦＣＢ１およびＦＣＢ２は変電所ＤＳＳに設置されて、それぞれ配電線Ｆ１、Ｆ２を引き出すための配電線遮断器であり、通常は「入」の状態にある。配電線Ｆ１は通常「入」状態（常閉）の開閉器Ｓ１、Ｓ２、Ｓ３、Ｓ４により区間１−１、１−２、１−３、１−４、１−５に区分されている。配電線Ｆ２も同様に通常「入」状態（常閉）の開閉器Ｓ１１、Ｓ１０、Ｓ１２により区間２−１、２−１、２−３、２−４に区分されている。区間１−２は通常「切」状態（常開）の開閉器Ｓ５を介して配電線Ｆ３に接続されており、以下同様に区間１−３は開閉器Ｓ６により配電線Ｆ４に、区間１−４は開閉器Ｓ７とＳ８により配電線Ｆ５とＦ６に、区間１−５は開閉器Ｓ９により配電線Ｆ２に、区間２−４は開閉器Ｓ１３により配電線Ｆ７にそれぞれ接続されている。   FCB1 and FCB2 are distribution line circuit breakers that are installed in the substation DSS to draw out the distribution lines F1 and F2, respectively, and are normally in the “ON” state. Distribution line F1 is normally divided into sections 1-1, 1-2, 1-3, 1-4, and 1-5 by switches S1, S2, S3, and S4 in an “on” state (normally closed). Similarly, the distribution line F2 is divided into sections 2-1, 2-1, 2-3, and 2-4 by switches S 11, S 10, and S 12 in a normal “ON” state (normally closed). The section 1-2 is connected to the distribution line F3 via the switch S5 that is normally in the “off” state (normally open). Similarly, the section 1-3 is connected to the distribution line F4 by the switch S6. 4 is connected to distribution lines F5 and F6 by switches S7 and S8, section 1-5 is connected to distribution line F2 by switch S9, and section 2-4 is connected to distribution line F7 by switch S13.

そして、各開閉器Ｓ１〜Ｓ１３には各区間の電源側配電線および負荷側配電線をそれぞれ制御電源とする開閉器遠方監視制御子局Ｃ１〜Ｃ１３が取り付けられており、これら開閉器遠方監視制御子局Ｃ１〜Ｃ１３は、通信路Ｌを介して変電所ＤＳＳ内に設けられた変電所監視制御子局Ｃｄ、遠方監視制御親局２を経て本実施形態による配電系統操作装置１Ａに接続されている。この配電系統操作装置１Ａは、変電所ＤＳＳの遮断器ＦＣＢ１、ＦＣＢ２、・・・や、図示していない保護リレーの状態、配電線の負荷電流や電圧が監視・計測可能なようになっている。 The switches S1 to S13 are equipped with switch remote monitoring control slave stations C1 to C13 that use the power distribution line and the load distribution line in each section as control power sources, respectively. The slave stations C1 to C13 are connected to the distribution system operating device 1A according to the present embodiment via the communication path L via the substation monitoring control slave station Cd and the remote monitoring control master station 2 provided in the substation DSS. Yes. This distribution system operating device 1A can monitor and measure the circuit breakers FCB1, FCB2,... Of the substation DSS, the state of a protection relay (not shown), the load current and voltage of the distribution line. .

このように構成された本実施形態において、配電線Ｆ１に事故が発生したとすると、変電所監視制御子局Ｃｄから遠方監視制御親局２に配電線事故発生情報が通知され、配電系統操作装置１Ａに設けられている監視手段１０１に通知される。この時の配電線遮断器ＦＣＢ１および配電線Ｆ１に設置された開閉器Ｓ１〜Ｓ４の動作を図６のタイムチャートに示す。   In the present embodiment configured as described above, if an accident occurs in the distribution line F1, distribution line accident occurrence information is notified from the substation monitoring control slave station Cd to the remote monitoring control master station 2, and the distribution system operation device The monitoring unit 101 provided in 1A is notified. The operation of switches S1 to S4 installed in distribution line breaker FCB1 and distribution line F1 at this time is shown in the time chart of FIG.

配電線Ｆ１に事故が発生した時点（図６の［ｉ］）では、配電線Ｆ１の事故により配電線遮断器ＦＣＢ１が遮断し、配電線Ｆ１を区分する常閉の開閉器Ｓ１〜Ｓ４は無電圧開放しており、どの区間に事故があるのか、まだ判らない。   At the time when an accident occurs in the distribution line F1 ([i] in FIG. 6), the distribution line breaker FCB1 is cut off due to the accident in the distribution line F1, and there are no normally closed switches S1 to S4 that divide the distribution line F1. The voltage has been released and it is not yet known which section has the accident.

監視手段１０１では遠方監視制御親局２から通知された配電線事故発生情報により配電線Ｆ１の事故と認識し、事故配電線を融通送電手順作成手段１０２に通知する。   The monitoring means 101 recognizes the accident of the distribution line F1 from the distribution line accident occurrence information notified from the remote monitoring control master station 2, and notifies the flexible power transmission procedure creating means 102 of the accident distribution line.

融通送電手順作成手段１０２は、この通知を受けて系統データ３０１をもとに配電線Ｆ１の全区間１−１、１−２、１−３および１−４について、１区間ずつを仮の事故区間とし、仮の事故区間から電源側区間は全て変電所側からの送電により充電されているものとして、他の健全停電区間に対する融通送電手順を作成する。   In response to this notification, the flexible power transmission procedure creating means 102 performs a temporary accident for each section 1-1, 1-2, 1-3, and 1-4 of the distribution line F1 based on the system data 301. Assuming that all sections from the temporary accident section to the power supply section are charged by power transmission from the substation side, a flexible power transmission procedure for other healthy power outage sections is created.

これを詳細に説明すると、融通送電手順作成手段１０２では、まず、区間１−１を仮の事故区間として、他の健全停電区間１−２、１−３、１−４および１−５に対する融通送電手順を作成する。融通送電手順の作成は一般的には、どの連係配電線から融通送電するかの融通ルート決定の条件として、（１）過負荷が発生しないこと。（２）良質な電気（融通送電後の電圧降下量が許容値内）が融通できること。（３）融通送電後の配電線予備力が残ること。などを計算パラメータとして考慮して計算する。なお、融通送電手順の作成方法が本発明の主旨ではないのでここでは詳述はしないが、例えば、区間１−１を仮の事故区間とした場合、
開閉器Ｓ９・・・「入」、
開閉器Ｓ７・・・「入」、
開閉器Ｓ６・・・「入」、
開閉器Ｓ５・・・「入」、
となる融通送電手順が作成される。 This will be described in detail. In the interchange power transmission procedure creating means 102, first, the section 1-1 is assumed to be a temporary accident section, and the accommodation for the other healthy power outage sections 1-2, 1-3, 1-4, and 1-5 is performed. Create a transmission procedure. In general, the creation of a flexible power transmission procedure is as follows: (1) Overload does not occur as a condition for determining a flexible route to determine which linked distribution line is to be used for flexible power transmission. (2) Good quality electricity (the amount of voltage drop after flexible transmission is within the allowable value) can be accommodated. (3) Distribution line reserves after interchange transmission remain. And so on as a calculation parameter. In addition, since the creation method of the interchange power transmission procedure is not the gist of the present invention, it will not be described in detail here. For example, when the section 1-1 is a temporary accident section,
Switch S9 ... "On",
Switch S7 ... "On",
Switch S6 ... "On",
Switch S5 ... "On",
A flexible power transmission procedure is created.

ここで補足説明すると、開閉器Ｓ９が投入され、区間１−５が充電されても開閉器Ｓ４は投入されない。これは一般的に開閉器遠方監視制御子局の機能として逆送防止機能があるためである。同様に開閉器Ｓ７が投入されても開閉器Ｓ３は逆送防止機能により投入されない。以下開閉器Ｓ６、Ｓ５の投入による開閉器Ｓ２、Ｓ１の動作も同様である。   If it explains supplementarily here, switch S4 will not be turned on even if switch S9 is thrown in and section 1-5 is charged. This is because there is generally a reverse transmission prevention function as a function of the switch remote monitoring control slave station. Similarly, even if the switch S7 is turned on, the switch S3 is not turned on by the reverse feed prevention function. The same applies to the operations of the switches S2 and S1 when the switches S6 and S5 are turned on.

作成された融通送電手順１０４は、区間１−１を仮の事故区間とした場合の融通送電手順１０４として、融通送電手順記憶手段１０３によって記憶装置３に記憶される。   The created accommodation power transmission procedure 104 is stored in the storage device 3 by the accommodation power transmission procedure storage means 103 as the accommodation power transmission procedure 104 when the section 1-1 is a temporary accident section.

次に、区間１−２を仮の事故区間として、他の健全停電区間１−３、１−４、１−５に対する融通送電手順１０４を作成する。この場合、仮の事故区間１−２よりも電源側の区間１−１は変電所側からの送電により充電したとして、区間１−１に対する融通送電手順は作成しない。これは、実系統において事故区間よりも電源側の区間は配電線遮断器ＦＣＢ１の再閉路、再々閉路動作と、開閉器の時限順送機能により送電されるためである。   Next, the interchange power transmission procedure 104 for the other healthy power failure sections 1-3, 1-4, and 1-5 is created with the section 1-2 as a temporary accident section. In this case, assuming that the section 1-1 on the power supply side than the temporary accident section 1-2 is charged by power transmission from the substation side, the flexible power transmission procedure for the section 1-1 is not created. This is because, in the actual system, power is transmitted in the section on the power supply side from the accident section by the reclosing and reclosing operation of the distribution line breaker FCB1 and the timed sequential transmission function of the switch.

そして、作成された融通送電手順は、区間１−２を仮の事故区間とした場合の融通送電手順１０４として、融通送電手順記憶手段１０３によって記憶装置３に記憶される。   The created flexible power transmission procedure is stored in the storage device 3 by the flexible power transmission procedure storage unit 103 as a flexible power transmission procedure 104 when the section 1-2 is a temporary accident section.

この区間１−２を仮の事故区間とした場合、
開閉器Ｓ９・・・「入」、
開閉器Ｓ７・・・「入」、
開閉器Ｓ６・・・「入」、
となる融通送電手順が作成される。 When this section 1-2 is a temporary accident section,
Switch S9 ... "On",
Switch S7 ... "On",
Switch S6 ... "On",
A flexible power transmission procedure is created.

次に、区間１−３を仮の事故区間として、他の健全停電区間１−４、１−５に対する融通送電手順１０４を作成する。作成された融通送電手順１０４は、融通送電手順記憶手段１０３によって記憶装置３に記憶される。   Next, the interchange power transmission procedure 104 for the other healthy power failure sections 1-4 and 1-5 is created with the section 1-3 as a temporary accident section. The created interchange power transmission procedure 104 is stored in the storage device 3 by the interchange power transmission procedure storage means 103.

この区間１−３を仮の事故区間とした場合、
開閉器Ｓ９・・・「入」、
開閉器Ｓ７・・・「入」、
となる融通送電手順が作成され、融通送電手順記憶手段１０３によって記憶装置３に記憶される。 If this section 1-3 is a temporary accident section,
Switch S9 ... "On",
Switch S7 ... "On",
A flexible power transmission procedure is created and stored in the storage device 3 by the flexible power transmission procedure storage means 103.

以降、同様にして区間１−４、１−５をそれぞれ仮の事故区間とした場合の、他の健全停電区間に対する融通送電手順１０４を作成し、それぞれ融通送電手順記憶手段１０３によって記憶装置３に記憶される。   Thereafter, similarly, the interchange power transmission procedure 104 for the other healthy power outage sections when the sections 1-4 and 1-5 are respectively assumed to be temporary accident sections is created and stored in the storage device 3 by the interchange power transmission procedure storage means 103, respectively. Remembered.

その後、図６のタイムチャートに示すように、配電線遮断器ＦＣＢ１は初回の事故遮断（タイムチャートの［ｉ］時点）から例えば３０秒後に再閉路し（タイムチャートの
［ii］時点）、区間１−１が充電されると開閉器Ｓ１が時限順送機能により投入される。 Thereafter, as shown in the time chart of FIG. 6, the distribution line breaker FCB1 is reclosed after 30 seconds from the first accident interruption (time point [i] in the time chart) (time point [ii] in the time chart). When 1-1 is charged, the switch S1 is turned on by a timed sequential function.

開閉器Ｓ１の投入により区間１−２が充電されると、次に開閉器Ｓ２が同様に時限順送機能により投入される。ここで、事故が区間１−３にあったとすると、開閉器Ｓ２が投入されるとともに事故電流が流れるため、変電所側保護リレーにより再度事故が検出され、配電線遮断器ＦＣＢ１を再遮断する（タイムチャートの［iii］時点）。   When the section 1-2 is charged by turning on the switch S1, the switch S2 is then turned on by the timed sequential feed function. Here, if the accident is in the section 1-3, the switch S2 is turned on and an accident current flows. Therefore, the accident is detected again by the substation-side protection relay, and the distribution line breaker FCB1 is shut off again ( Time point [iii]).

このとき、開閉器Ｓ２は事故点投入を検出して投入ロック状態となる。さらに配電線遮断器ＦＣＢ１は、再遮断の時点［iii］から例えば６０秒後に再々閉路（［iv］時点）して区間１−１が充電されると開閉器Ｓ１が時限順送機能により投入され、区間１−２が充電される。区間１−２が充電されても開閉器Ｓ２は上述のように投入ロックされているので投入されない。   At this time, the switch S2 detects the accident point input and enters the input lock state. Furthermore, the distribution circuit breaker FCB1 is closed again (time point [iv]), for example, 60 seconds after the time point [iii] of re-breaking, and when the section 1-1 is charged, the switch S1 is turned on by the timed sequential feeding function. The section 1-2 is charged. Even if the section 1-2 is charged, the switch S2 is not turned on because it is turned on and locked as described above.

監視手段１０１では、配電線遮断器ＦＣＢ１の事故遮断動作（時点［ｉ］）から再々閉路（時点［iv］）動作までを監視するとともに、再々閉路後（時点［ｖ］）に通信路Ｌを介して開閉器Ｓ２が「切」状態で投入ロックを監視した上で、事故区間を１−３と判定し、配電線事故区間情報を制御手段１０５に通知する。   The monitoring means 101 monitors the operation from the fault interruption operation (time [i]) to the re-closing (time [iv]) operation of the distribution line circuit breaker FCB1 and also sets the communication path L after the re-closing (time [v]). Then, the switch S2 is in the “OFF” state and the lock is monitored, and then the accident section is determined as 1-3, and the distribution line accident section information is notified to the control means 105.

制御手段１０５は、この通知を受けると、区間１−３を仮の事故区間として記憶装置３に記憶されている融通送電手順１０４を直ちに取り出して、その融通送電手順１０４に従って遠方監視制御親局２を経由して開閉器遠方監視制御子局Ｃ９，Ｃ７・・・に制御指令を出力し、配電系統の開閉器Ｓ９，Ｓ７・・・を遠方制御する。   Upon receipt of this notification, the control means 105 immediately takes out the interchange power transmission procedure 104 stored in the storage device 3 with the section 1-3 as a tentative accident section, and the remote monitoring control master station 2 according to the interchange power transmission procedure 104 The control commands are output to the remote switch control stations C9, C7,... Via the switch, and the switches S9, S7,.

以上述べたように第１の実施形態によれば、配電線事故発生時に融通送電手順を作成しているので、遮断器の再々閉路後の事故区間判定後に融通送電手順作成のための処理時間を要することなく直ちに融通送電操作を行うことができる。   As described above, according to the first embodiment, the flexible power transmission procedure is created when a distribution line fault occurs. Therefore, the processing time for creating the flexible power transmission procedure is determined after the fault section determination after the re-closing of the circuit breaker. A flexible power transmission operation can be performed immediately without the need.

（第２の実施形態）
次に、図２を参照して本発明に係わる配電系統操作装置の第２の実施形態について説明する。
図２は、本実施形態に係わる配電系統操作装置の構成を示すブロック図である。
本実施の形態は、前述した第１の実施形態に比べて異なる点は次の２点である。 (Second Embodiment)
Next, a second embodiment of the power distribution system operating device according to the present invention will be described with reference to FIG.
FIG. 2 is a block diagram showing the configuration of the power distribution system operating device according to the present embodiment.
The present embodiment is different from the first embodiment described above in the following two points.

まず、第１点目は、開閉器遠方監視制御子局Ｃ１〜Ｃ１３を、予備電源を備えた開閉器遠方監視制御子局Ｃ１Ａ〜Ｃ１３Ａに置換することにより、配電線遮断器の遮断により配電線が停電している状態においても、開閉器遠方監視制御子局Ｃ１Ａ〜Ｃ１３Ａと遠方監視制御親局２との間で監視制御のための通信を可能にした点である。   First, the first point is that the remote control circuit slave stations C1 to C13 are replaced with the remote monitor control slave stations C1A to C13A equipped with a standby power source, and the distribution line breaker is cut off. Even in a state where the power failure occurs, it is possible to perform communication for monitoring control between the switch remote monitoring control slave stations C1A to C13A and the remote monitoring control master station 2.

第２点目は、監視手段１０１を監視手段１０１Ａに置換して、配電線遮断器の再遮断後に投入ロック信号を受け入れることにより配電線事故区間を判定できるようにした点である。   The second point is that the monitoring unit 101 is replaced with the monitoring unit 101A so that the distribution line fault section can be determined by accepting the closing lock signal after the distribution line breaker is re-blocked.

以下図２を参照して図１と異なる点を中心に説明する。
前述した第１の実施形態（図１）においては、再々閉路後の図６の［ｖ］の時点で通信路Ｌを介して開閉器Ｓ２が「切」状態で投入ロックされたことを監視した上で、事故区間を１−３と判定し、配電線事故区間情報を制御手段１０５に通知するとともに、制御手段１０５では直ちに融通送電手順１０４に記憶されている区間１−３を仮の事故区間として作成されている融通送電手順を取り出し、その融通送電手順に従って配電系統の開閉器を遠方制御するとしたが、これは再々閉路後まで事故区間の判定ができないためである。 Hereinafter, the difference from FIG. 1 will be mainly described with reference to FIG.
In the first embodiment (FIG. 1) described above, it was monitored that the switch S2 was turned on and locked in the “off” state via the communication path L at the time of [v] in FIG. In the above, the accident section is determined as 1-3, and the distribution line accident section information is notified to the control means 105. The control means 105 immediately sets the section 1-3 stored in the interchange power transmission procedure 104 as a temporary accident section. It is assumed that the interchanged power transmission procedure created as is taken out and the switch of the distribution system is remotely controlled according to the interchanged power transmission procedure, because the fault section cannot be determined until after it is closed again.

実際には、図６に示すタイムチャートの［iii］の時点、すなわち、遮断器ＦＣＢ１の再閉路後に開閉器Ｓ２が時限順送機能により投入されて遮断器ＦＣＢ１が再遮断した時点（［iii］）において、開閉器Ｓ２は「切」状態で投入ロック（すなわち事故区間確定）状態となっている。しかし、一般的に開閉器遠方監視制御子局Ｃ２はそれが取り付けられた配電線を動作電源として稼動するように構成されているため、停電中は監視できない。   Actually, at the time point [iii] of the time chart shown in FIG. 6, that is, when the switch S2 is turned on by the timed sequential feed function after the circuit breaker FCB1 is closed again ([iii] ), The switch S <b> 2 is in the “OFF” state and is in the closing lock state (that is, the accident section is determined). However, since the switch remote monitoring control slave station C2 is generally configured to operate using the distribution line to which the switch is attached as an operation power supply, it cannot be monitored during a power failure.

従って、配電線遮断器が再々閉路し、開閉器Ｓ１が時限順送機能によって投入され、区間１−２が充電された後でなければ開閉器Ｓ２の監視ができないためである。   Therefore, the distribution line circuit breaker is closed again, the switch S1 is turned on by the timed sequential feeding function, and the switch S2 can be monitored only after the section 1-2 is charged.

そこで、第２の実施形態では、配電線が停電していても監視のための通信が可能なように太陽電池や蓄電池等の予備電源を備えた開閉器遠方監視制御子局Ｃ１Ａ〜Ｃ１３Ａを採用して再遮断時の投入ロック信号を通信路Ｌ、変電所監視制御子局Ｃｄ、遠方監視制御親局２を介して配電系統操作装置１Ｂの監視手段１０１Ａに入力できるようにしたものである。   Therefore, in the second embodiment, switch remote monitoring control slave stations C1A to C13A equipped with a standby power source such as a solar battery or a storage battery are adopted so that monitoring communication is possible even if the distribution line is out of power. Thus, the closing lock signal at the time of re-shutoff can be input to the monitoring means 101A of the distribution system operating device 1B via the communication path L, the substation monitoring control slave station Cd, and the remote monitoring control master station 2.

このように構成された本実施形態において、配電線Ｆ１に事故が発生したとすると、第１の実施形態で述べたと同様にして監視手段１０１Ａが事故発生を検出すると、配電線Ｆ１の全区間について、１区間ずつを仮の事故区間とし、仮の事故区間より電源側区間は全て変電所側からの送電により充電したとして、他の健全停電区間に対する融通送電手順を作成し、融通送電手順記憶手段１０３により融通送電手順１０４に記憶する。   In the present embodiment configured as described above, if an accident occurs in the distribution line F1, if the monitoring means 101A detects the occurrence of the accident in the same manner as described in the first embodiment, the entire section of the distribution line F1 is detected. Assuming that each section is a temporary accident section, and that all sections on the power supply side from the temporary accident section are charged by power transmission from the substation side, a flexible power transmission procedure for other healthy power outage sections is created, and flexible power transmission procedure storage means 103 is stored in the interchange power transmission procedure 104.

その後、配電線Ｆ１は図６のタイムチャートに示すように、配電線遮断器ＦＣＢ１は初回の事故遮断から例えば３０秒後に再閉路し、区間１−１が充電されると開閉器Ｓ１が時限順送機能により投入される。開閉器Ｓ１の投入により区間１−２が充電されると次に開閉器Ｓ２が同様に時限順送機能により投入される。   Thereafter, as shown in the time chart of FIG. 6, the distribution line circuit breaker FCB1 is reclosed, for example, 30 seconds after the first accident interruption, and when the section 1-1 is charged, the switch S1 is arranged in chronological order. Input by the sending function. When the section 1-2 is charged by turning on the switch S1, the switch S2 is similarly turned on by the timed sequential feed function.

ここで、事故が区間１−３にあったとすると、事故区間１−３よりも開閉器Ｓ２が投入されると直ちに変電所側保護リレーが再度事故を検出し、配電線遮断器ＦＣＢ１を再遮断する。   Assuming that the accident occurred in section 1-3, immediately after switch S2 is turned on than in accident section 1-3, the substation-side protection relay detects the accident again and re-breaks distribution line breaker FCB1. To do.

このとき、電源側に位置する開閉器Ｓ２に取り付けられている開閉器遠方監視制御子局Ｃ２は、自己の開閉器Ｓ２投入時点から所定時間以内の事故であること、すなわち事故点投入であることを検出して開閉器Ｓ２を投入ロック状態にする。そして、この投入ロック状態信号を配電線の停電中に係わらず、予備電源によって通信路Ｌ、遠方監視制御親局２を介して監視手段１０１Ａに通知する。   At this time, the switch remote monitoring control slave station C2 attached to the switch S2 located on the power source side is an accident within a predetermined time from the time when the switch S2 is turned on, that is, the accident point is turned on. Is detected to place the switch S2 in the closing lock state. The input lock state signal is notified to the monitoring means 101A via the communication path L and the remote monitoring control master station 2 by the standby power supply regardless of the power failure of the distribution line.

監視手段１０１Ａでは開閉器遠方監視制御子局Ｃ２からの投入ロック信号を受信すると、開閉器Ｓ２の負荷側区間１−３が事故区間であると判定し、制御手段１０５に通知する。制御手段１０５では、直ちに融通送電手順１０４に記憶されている区間１−３を仮の事故区間として作成されている融通送電手順を取り出し、その融通送電手順に従って遠方監視制御親局２、通信路Ｌを介して該当する開閉器遠方監視制御子局に制御指令を出力し、配電系統の開閉器を遠方制御する。   When the monitoring means 101A receives the closing lock signal from the switch remote monitoring control slave station C2, the monitoring means 101A determines that the load side section 1-3 of the switch S2 is an accident section and notifies the control means 105 of it. In the control means 105, the section 1-3 stored in the accommodation power transmission procedure 104 is immediately extracted as a provisional accident section, and the remote monitoring control master station 2 and the communication path L are extracted according to the accommodation power transmission procedure. The control command is output to the remote switch / remote control slave station corresponding to the switch, and the switch of the distribution system is controlled remotely.

この第２の実施形態では、図６のタイムチャートに示す［iii］の再遮断時点の直後から融通送電操作を実施するため、事故区間１−３より負荷側の区間１−４、１−５が先に融通送電され、その後配電線遮断器ＦＣＢ１の再々閉路により区間１−１、１−２が送電されることになる。   In the second embodiment, since the interchange power transmission operation is carried out immediately after the re-interruption time of [iii] shown in the time chart of FIG. 6, sections 1-4 and 1-5 on the load side from the accident section 1-3. Is transmitted first, and then the sections 1-1 and 1-2 are transmitted by re-closing the distribution line breaker FCB1.

以上述べたように第２の実施形態によれば、開閉器遠方監視制御子局は、予備電源を備えているので、配電線遮断器の遮断により配電線が停電している状態においても、遠方監視制御親局との間で監視制御のための通信が可能なので、配電線事故発生時に融通送電手順を作成することができ、配電線遮断器の再遮断後に開閉器遠方監視制御子局からの投入ロック信号を受信すると、融通送電手順作成のための処理時間を要することなく直ちに融通送電操作を行うことができる。   As described above, according to the second embodiment, since the switch remote monitoring control slave station is provided with a standby power supply, even in a state where the distribution line is interrupted by the interruption of the distribution line breaker, it is far away. Communication for supervisory control is possible with the supervisory control master station, so it is possible to create a flexible transmission procedure when a distribution line fault occurs. When the closing lock signal is received, the flexible power transmission operation can be performed immediately without requiring processing time for creating the flexible power transmission procedure.

次に、図３を参照して本発明に係わる配電系統操作装置の第３の実施形態を説明する。
図３は、本実施形態に係わる配電系統操作装置の構成を示すブロック図である。
図３において、本実施形態による配電系統操作装置１Ｃは、前述した第１の実施形態の配電系統操作装置１Ａ、あるいは第２の実施形態の配電系統操作装置１Ｂに対して、融通操作実行指示を行う操作指示手段１０６を追加したことを特徴とするものである。 (Third embodiment)
Next, a third embodiment of the power distribution system operating device according to the present invention will be described with reference to FIG.
FIG. 3 is a block diagram showing the configuration of the power distribution system operating device according to the present embodiment.
In FIG. 3, the power distribution system operating device 1C according to the present embodiment issues an interchange operation execution instruction to the power distribution system operating device 1A according to the first embodiment or the power distribution system operating device 1B according to the second embodiment. The operation instruction means 106 to perform is added.

すなわち、第３の実施形態による配電系統操作装置１Ｃは、変電所状態や配電系統状態を監視する監視手段１０１（１０１Ａ）と、この監視手段１０１（１０１Ａ）により検出された電力供給支障事故発生時に、記憶装置３に記憶された系統データ３０１をもとに想定される全融通区間候補に対して融通送電手順を作成する融通送電手順作成手段１０２と、この融通送電手順作成手段１０２により作成された融通送電手順１０４を記憶装置３に記憶させる融通送電手順記憶手段１０３と、前記監視手段１０１により検出されたバンク事故情報に基づいて前記融通送電手順記憶手段１０３により融通送電手順１０４に記憶された融通送電手順を取り出して配電系統を制御する制御手段１０５と、融通操作実行指示を行う操作指示手段１０６から構成されている。   That is, the distribution system operating device 1C according to the third embodiment includes a monitoring unit 101 (101A) that monitors a substation state and a distribution system state, and a power supply trouble that is detected by the monitoring unit 101 (101A). An interchanged power transmission procedure creating unit 102 that creates a flexible transmission procedure for all assumed interchange section candidates based on the system data 301 stored in the storage device 3, and the interchanged power transmission procedure creating unit 102 The interchange power transmission procedure storage means 103 for storing the accommodation power transmission procedure 104 in the storage device 3 and the accommodation stored in the accommodation power transmission procedure 104 by the accommodation power transmission procedure storage means 103 based on the bank accident information detected by the monitoring means 101. From the control means 105 that takes out the power transmission procedure and controls the distribution system, and the operation instruction means 106 that gives the interchange operation execution instruction It has been made.

なお、遠方監視制御親局２が、通信路Ｌを介して配電系統に設置された開閉器に取り付けられた開閉器遠方監視制御子局および変電所監視制御子局と接続され、開閉器の遠方監視制御や変電所機器の監視を行うように構成されている点は前述の実施例と同じである。   The remote monitoring control master station 2 is connected to the switch remote monitoring control slave station and the substation monitoring control slave station attached to the switch installed in the power distribution system via the communication path L. The point which is comprised so that monitoring control and monitoring of a substation apparatus may be the same as the above-mentioned Example.

この第３の実施形態において、変電所ＤＳＳにバンク事故が発生したとすると、変電所監視制御子局Ｃｄから遠方監視制御親局２に通信路Ｌを介してバンク事故情報が通知され、さらに監視手段１０１に入力される。バンク事故が発生すると、図示しない保護リレーによって当該バンクに接続されている遮断器が遮断されるので、全ての配電線が停電する。   In this third embodiment, if a bank accident occurs in the substation DSS, the bank accident information is notified from the substation monitoring control slave station Cd to the remote monitoring control master station 2 via the communication path L, and further monitored. Input to means 101. When a bank accident occurs, a circuit breaker connected to the bank is interrupted by a protection relay (not shown), causing all power distribution lines to fail.

監視手段１０１では遠方監視制御親局２から入力した情報に基づいて、バンク事故と認識し、事故バンク情報を融通送電手順作成手段１０２に通知する。これを受けて融通送電手順作成手段１０２では、当該バンクに接続されている全ての配電線の全区間に対する融通送電手順を作成し、融通送電手順記憶手段１０３により融通送電手順１０４に記憶される。   The monitoring unit 101 recognizes a bank accident based on the information input from the remote monitoring control master station 2, and notifies the accident bank information to the flexible power transmission procedure creating unit 102. In response to this, the flexible power transmission procedure creating means 102 creates a flexible power transmission procedure for all sections of all the distribution lines connected to the bank, and stores it in the flexible power transmission procedure 104 by the flexible power transmission procedure storage means 103.

バンク事故時には一般的に事故発生後すぐには配電線側での融通送電操作は行わず、例えば同一変電所の他の健全なバンクからの送電を待つ。他の健全なバンクからの融通送電で当該バンクに接続されている全ての配電線が送電できれば、事故復旧操作は完了となる。しかし、他バンクからの送電が負荷的理由等により不可能な場合、当該バンクに接続されている配電線の配電側での融通送電が必要となる。この場合、操作指示手段１０６からオペレータが融通操作実行指示を行うと、制御手段１０５に通知され、制御手段１０５では、直ちに融通送電手順１０４に記憶されている融通送電手順を取り出し、その融通送電手順に従って開閉器遠方監視制御子局に制御指令を出力し、配電系統の開閉器を遠方制御し融通送電する。   In the event of a bank accident, generally, the power transmission operation on the distribution line side is not performed immediately after the occurrence of the accident, but for example, waiting for power transmission from another healthy bank of the same substation. If all the distribution lines connected to the bank can be transmitted by flexible transmission from another healthy bank, the accident recovery operation is completed. However, when power transmission from another bank is not possible due to a load or the like, flexible power transmission on the power distribution side of the distribution line connected to the bank is required. In this case, when the operator issues an accommodation operation execution instruction from the operation instruction means 106, the control means 105 is notified, and the control means 105 immediately takes out the accommodation power transmission procedure stored in the accommodation power transmission procedure 104, and the accommodation power transmission procedure. According to the above, a control command is output to the remote monitoring control slave station, and the switch of the distribution system is remotely controlled to allow for flexible power transmission.

以上述べたように第３の実施形態によれば、変電所バンク事故発生時に融通送電手順を作成しているので、オペレータが融通操作実行指示を行うと、融通送電手順作成のための処理時間を要することなく直ちに融通送電操作を行うことができる。   As described above, according to the third embodiment, the flexible power transmission procedure is created when the substation bank accident occurs. Therefore, when the operator gives the interchange operation execution instruction, the processing time for creating the flexible power transmission procedure is reduced. A flexible power transmission operation can be performed immediately without the need.

（第４の実施形態）

図４において、本実施形態は、前述した第３の実施形態の融通操作実行指示を行う操作指示手段１０６に替えて融通操作実行指示を行う操作指示通信入力手段１０７を設けたことを特徴とするものである。 (Fourth embodiment)
Next, a fourth embodiment of the power distribution system operating device according to the present invention will be described with reference to FIG.
FIG. 4 is a block diagram showing the configuration of the power distribution system operating device according to the present embodiment.
In FIG. 4, the present embodiment is characterized in that an operation instruction communication input means 107 for giving an accommodation operation execution instruction is provided in place of the operation instruction means 106 for giving the accommodation operation execution instruction of the third embodiment. Is.

すなわち、本実施形態の配電系統操作装置１Ｄは、変電所状態や配電系統状態を監視する監視手段１０１と、監視手段１０１により検出された電力供給支障事故発生時に、記憶装置３に記憶された系統データ３０１をもとに想定される全融通区間候補に対して融通送電手順を作成する融通送電手順作成手段１０２と、この融通送電手順作成手段１０２により作成された融通送電手順１０４を記憶する融通送電手順記憶手段１０３と、前記監視手段１０１により検出されたバンク事故情報に基づいて前記融通送電手順１０４に記憶された融通送電手順を取り出して配電系統を制御する制御手段１０５と、融通操作実行指示を行う操作指示通信入力手段１０７から構成されている。   That is, the distribution system operation device 1D according to the present embodiment includes a monitoring unit 101 that monitors a substation state and a distribution system state, and a system that is stored in the storage device 3 when a power supply trouble is detected by the monitoring unit 101. A flexible power transmission procedure creating means 102 for creating a flexible power transmission procedure for all possible flexible section candidates based on the data 301 and a flexible power transmission for storing a flexible power transmission procedure 104 created by the flexible power transmission procedure creating means 102. A procedure storage means 103, a control means 105 for controlling the distribution system by taking out the interchange power transmission procedure stored in the accommodation power transmission procedure 104 based on the bank accident information detected by the monitoring means 101, and an interchange operation execution instruction. The operation instruction communication input means 107 is configured to be performed.

操作指示通信入力手段１０７には、変電所を監視制御している図示していない制御所等の監視制御システムから通信路を介して操作指示入力が入力できるように構成されている。   The operation instruction communication input means 107 is configured so that an operation instruction input can be input via a communication path from a monitoring control system such as a control station (not shown) that monitors and controls the substation.

なお、遠方監視制御親局２が、通信路Ｌを介して図１と同様の配電系統に設置された開閉器に取り付けられた開閉器遠方監視制御子局Ｃ１〜Ｃ１３や、変電所監視制御子局Ｃｄに接続され、開閉器の遠方監視制御や変電所機器の監視を行うように構成されている点は前述の実施例と同じである。   It is to be noted that the remote monitoring control master station 2 is connected to the switch remote monitoring control slave stations C1 to C13 attached to the switch installed in the same distribution system as in FIG. It is the same as the above-described embodiment in that it is connected to the station Cd and is configured to perform remote monitoring control of the switch and monitoring of the substation equipment.

この第４の実施形態において、変電所にバンク事故が発生したとすると、変電所監視制御子局Ｃｄから遠方監視制御親局２に通信路Ｌを介してバンク事故情報が通知され、監視手段１０１に通知される。   In the fourth embodiment, if a bank accident occurs in the substation, the bank accident information is notified from the substation monitoring control slave station Cd to the remote monitoring control master station 2 via the communication path L. Will be notified.

バンク事故が発生すると、図示しない保護リレーによって当該バンクに接続されている遮断器が遮断されるので、全ての配電線が停電する。監視手段１０１ではバンク事故と認識し、事故バンク情報が融通送電手順作成手段１０２に通知される。融通送電手順作成手段１０２では、当該バンクに接続されている全ての配電線の全区間に対する融通送電手順を作成し、融通送電手順記憶手段１０３により融通送電手順１０４に記憶される。   When a bank accident occurs, a circuit breaker connected to the bank is interrupted by a protection relay (not shown), causing all power distribution lines to fail. The monitoring unit 101 recognizes the bank accident, and the accident bank information is notified to the flexible power transmission procedure creating unit 102. The interchanged power transmission procedure creating unit 102 creates a interchanged power transmission procedure for all sections of all distribution lines connected to the bank, and stores it in the interchanged power transmission procedure 104 by the interchanged power transmission procedure storage unit 103.

バンク事故時には一般的に事故発生後直ぐには配電線側での融通送電操作は行わず、例えば変電所を監視制御している制御所にて同一変電所の他バンクから送電したりする。制御所での他バンクからの融通送電で当該バンクに接続されている全ての配電線が送電できれば、事故復旧操作は完了となる。   In the event of a bank accident, generally, the power transmission operation on the distribution line side is not performed immediately after the accident occurs. For example, power is transmitted from another bank of the same substation at a control station that monitors and controls the substation. If all the distribution lines connected to the bank can be transmitted by flexible power transmission from another bank at the control station, the accident recovery operation is completed.

しかし、他バンクからの送電が負荷的理由等により不可能な場合、当該バンクに接続されている配電線の配電側での融通送電が必要となる。この場合、変電所を監視制御している制御所から通信路を介して操作指示通信入力手段１０７に融通操作実行指示が入力されると、制御手段１０５に通知され、制御手段１０５では、直ちに融通送電手順１０４に記憶されている融通送電手順を取り出し、その融通送電手順に従って開閉器遠方監視制御子局に制御指令を出力し、配電系統の開閉器を遠方制御し融通送電する。   However, when power transmission from another bank is not possible due to a load or the like, flexible power transmission on the power distribution side of the distribution line connected to the bank is required. In this case, when an interchange operation execution instruction is input to the operation instruction communication input unit 107 from the control station that monitors and controls the substation via the communication path, the control unit 105 is notified, and the control unit 105 immediately allows the interchange. The interchanged power transmission procedure stored in the power transmission procedure 104 is taken out, a control command is output to the switch remote monitoring control slave station in accordance with the interchanged power transmission procedure, and the switch of the distribution system is remotely controlled to perform flexible power transmission.

以上述べたように第４の実施形態によれば、変電所バンク事故発生時に融通送電手順を作成しているので、制御所からの融通操作実行指示が入力されると、融通送電手順作成のための処理時間を要することなく直ちに融通送電操作を行うことができる。   As described above, according to the fourth embodiment, since an interchange transmission procedure is created when a substation bank fault occurs, when an interchange operation execution instruction is input from the control center, the interchange transmission procedure is created. Therefore, the flexible power transmission operation can be performed immediately without requiring the processing time.
