Description
本発明の実施形態は、複数の開閉器と複数の電圧検出装置とを含む受変電設備の操作を支援する受変電設備操作支援システムに関する。 An embodiment of the present invention relates to a substation facility operation support system that supports operation of a substation facility including a plurality of switches and a plurality of voltage detection devices.
従来、受変電設備は、各負荷設備へ電力を配電する機能を有する。受変電設備を構成する機器には、遮断器、断路器、負荷開閉器などの多くの開閉器がある。一般に、開閉器はシステム上、分岐路となる箇所に設置される。事故時の自動遮断の他、保守時等に、これらの開閉器のオンオフ操作を実行する。保守を開始する場合は、開閉器のオフ操作を実行して、システムの回路や設備を停電状態に導き、保守が終わった場合は、開閉器のオン操作を実行して、活線状態に導く。 Conventionally, power receiving and transforming equipment has a function of distributing electric power to each load equipment. There are many switches, such as a circuit breaker, a disconnecting switch, and a load switch, as devices constituting a substation facility. Generally, a switch is installed at a location that becomes a branch in the system. In addition to automatic shutoff in the event of an accident, on / off operations of these switches are performed during maintenance or the like. When maintenance is started, the switch is turned off to bring the system circuits and equipment into a power outage state, and when maintenance is completed, the switch is turned on to lead to the live state. .
開閉器によっては、引出機構を有しているものがある。引出機構とは、開閉器本体を回路から簡易に切り離せる機構であり、一般に、点検や試験、機器更新を容易にするために採用される。引出位置では、開閉器は、主回路と電気的に切り離された状態となるが、開閉器の制御機構は試験のため接続された状態を維持することが可能である。このため、開閉器が引出位置にある場合は、回路上は切で、開閉器自身は入の状態となるケースがある。 Some switches have a draw-out mechanism. The pull-out mechanism is a mechanism that allows the switch body to be easily separated from the circuit, and is generally employed to facilitate inspection, testing, and equipment replacement. In the extracted position, the switch is electrically disconnected from the main circuit, but the control mechanism of the switch can be kept connected for testing. For this reason, when the switch is in the drawn-out position, there is a case where the circuit is turned off and the switch itself is turned on.
また、回路における電圧の有無を検出する装置として、計器用変圧器（ＶＴ）や接地形計器用変圧器（ＥＶＴ）、電圧検出器（ＶＤ）などがある。これらの電圧検出装置は、一般に回路電圧の有無を検出し、検出した回路電圧の有無は、系統を切り替えたり、発電機を起動したりするためのトリガ信号に用いられる。 Devices for detecting the presence or absence of a voltage in a circuit include an instrument transformer (VT), a grounded instrument transformer (EVT), and a voltage detector (VD). These voltage detection devices generally detect the presence or absence of a circuit voltage, and the presence or absence of the detected circuit voltage is used as a trigger signal for switching systems or activating a generator.
一方、設備保守の観点から見た場合、開閉器で区分された個々の回路毎に、電圧を検出する装置が設けられていることが望ましい。しかし、費用面から一部の回路の適用に留まっていることが多い。したがって、保守員が、システム上に設置された電圧検出装置の電圧の有無の情報と、開閉器のオンオフの情報とから、任意の回路における活線状態または停電状態の判断や、操作しようとする回路の状態の推定を行わなければならない。しかし、システムが複雑である場合には、システムの回路の状態を誤って推定してしまう場合がある。システムが複雑になると、この様相は顕著になり、開閉器の入切操作後の各回路の電圧有無が予測し辛くなる。また、開閉器が引出位置にある場合は、回路上は切で、開閉器自身は入の状態となるケースがある。そのため、引出位置では、開閉器のオンオフ状態とは無関係にシステム上非接続状態となるため、その判断を一層難しくしている。 On the other hand, from the viewpoint of facility maintenance, it is preferable that a device for detecting voltage is provided for each circuit divided by the switch. However, in many cases, only some circuits are applied in terms of cost. Therefore, the maintenance person attempts to determine the hot-line state or the power failure state in an arbitrary circuit or to operate the information from the information on the presence or absence of the voltage of the voltage detection device installed on the system and the information on the ON / OFF of the switch. An estimation of the state of the circuit must be made. However, if the system is complicated, the state of the circuit of the system may be erroneously estimated. When the system becomes complicated, this aspect becomes remarkable, and it becomes difficult to predict the presence or absence of the voltage of each circuit after the switching operation of the switch. Further, when the switch is in the drawn-out position, there is a case where the circuit is turned off and the switch itself is turned on. For this reason, at the pull-out position, the switch is disconnected from the system irrespective of the ON / OFF state of the switch, which makes the determination more difficult.
本発明の実施形態は、上記のような従来技術の問題点を解決するために提案されたものである。その目的は、保守時に受変電設備の回路状況を簡単に把握できる受変電設備操作支援システムを提供することである。 Embodiments of the present invention have been proposed to solve the above-described problems of the related art. An object of the present invention is to provide a power receiving and transforming facility operation support system that can easily grasp the circuit status of the power receiving and transforming facility during maintenance.

An instrument transformer (VT) is used to determine whether a power outage has occurred. It is also used to measure relatively small voltages. A grounded instrument transformer (EVT) is basically the same as an instrument transformer, but is used for special applications such as zero-phase voltage detection. The voltage detector (VD) detects the presence or absence of the transmission voltage from the power company, and transmits it to each site monitoring device 6, the remote station panel 7, and the central monitoring facility 5, and the transmitted data is used for system switching and the like.

電圧検出装置４のうちで、電圧検出器（ＶＤ）は、電圧を検出した場合は、パラメータとしてオン信号を送信し、電圧を検出しない場合は、オフ信号を送信する。計器用変圧器（ＶＴ）および接地形計器用変圧器（ＥＶＴ）は、二次電圧を検出する不足電圧継電器がオフ情報を検出した場合に、電圧検出「有」としてオン信号を送信し、不足電圧継電器がオン情報を検出した場合に、電圧検出「無」としてオフ信号を送信する。 In the voltage detector 4, a voltage detector (VD) transmits an ON signal as a parameter when detecting a voltage, and transmits an OFF signal when not detecting a voltage. The instrument transformer (VT) and the grounded instrument transformer (EVT) transmit an ON signal as voltage detection “Yes” when an undervoltage relay that detects a secondary voltage detects OFF information, and transmits an ON signal. When the voltage relay detects the ON information, the OFF signal is transmitted as voltage detection “absent”.

(Configuration of the site monitoring device 6)

演算部６４は、ＰＬＣ（プログラマブルコントローラ）等であり、処理として表示画面制御処理６４１と回路状態判定処理６４２と訓練・通常モード選択処理６４３とを行う。演算部６４は、回路状態判定処理６４２として、受変電設備５上の開閉器３および電圧検出装置４から開閉器３の接続状態および引出状態並びに電圧検出装置４の電圧検出状態のパラメータを取得し、コントローラのパラメータに基づいて、受変電設備５上の開閉器３で区切られた回路単位の電圧の有無を判別する。パラメータには、電圧検出装置４による電圧の有無の情報や、開閉器３の入・切情報や、引出機構の接続・引出位置の情報がある。演算部６４は、開閉器３で区分された回路の電圧の有無を以下のパラメータからシーケンサ等で演算することで、開閉器３で区切られた回路単位の電圧有無表示を可能とする。演算部６４は、開閉器３の接続状態を下記の表１に従って判定する。具体的には、開閉器３が筐体に対する接続位置にあり、かつ、開閉器３のスイッチが入っている場合には、この開閉器３はオンであると判別され、開閉器３が筐体に対する引出位置にある、または、開閉器３のスイッチが切られている場合には、この開閉器はオフであると判別される。また、演算部６４は、電圧検出装置４が電圧を検出した二つの開閉器３で区切られた回路および当該回路と入状態の開閉器３で接続された回路を電圧が有ると判別する。 The calculation unit 64 is a PLC (programmable controller) or the like, and performs a display screen control process 641, a circuit state determination process 642, and a training / normal mode selection process 643 as processes. The arithmetic unit 64 obtains, from the switch 3 and the voltage detection device 4 on the power receiving and transforming equipment 5, parameters of a connection state and an extraction state of the switch 3 and a voltage detection state of the voltage detection device 4 as a circuit state determination process 642. Then, based on the parameters of the controller, it is determined whether or not there is a voltage for each circuit unit separated by the switch 3 on the power receiving and transforming facility 5. The parameters include information on the presence or absence of a voltage by the voltage detection device 4, on / off information on the switch 3, and information on the connection / extraction position of the extraction mechanism. The arithmetic unit 64 calculates the presence / absence of the voltage of the circuit divided by the switch 3 using a sequencer or the like from the following parameters, thereby enabling the presence / absence display of the voltage of each circuit divided by the switch 3. The calculation unit 64 determines the connection state of the switch 3 according to Table 1 below. Specifically, when the switch 3 is at the connection position with respect to the housing and the switch 3 is turned on, the switch 3 is determined to be on, and the switch 3 is turned on. , Or the switch 3 is turned off, the switch is determined to be off. In addition, the arithmetic unit 64 determines that there is a voltage in the circuit separated by the two switches 3 from which the voltage is detected by the voltage detection device 4 and the circuit connected to the circuit by the switch 3 in the ON state.
また、演算部６４は、開閉器３の一次側および二次側の両方または一方の電圧の有無を判別する。詳述すると、演算部６４は、電圧が有る旨の信号を受信した電圧検出装置４と接続される、開閉器３で区切られた部分の回路を電圧有（活線）とする。また、演算部６４は、開閉器３の状態をオンと判定し、当該開閉器３と接続される回路の上流の電圧がある場合は、当該開閉器３と接続される一次側および二次側の回路を電圧有（活線）と判定する。演算部６４は、開閉器３の状態をオフと判定した場合は、当該開閉器３と接続される二次側の回路を電圧無の状態と判定する。 In addition, the calculation unit 64 determines whether or not there is a voltage on both or one of the primary side and the secondary side of the switch 3. More specifically, the arithmetic unit 64 sets the circuit of the portion, which is connected to the voltage detecting device 4 that has received the signal indicating that the voltage is present, divided by the switch 3 to have a voltage (hot line). The operation unit 64 determines that the state of the switch 3 is ON, and when there is a voltage upstream of a circuit connected to the switch 3, the primary side and the secondary side connected to the switch 3 Circuit is determined to have voltage (hot line). When determining that the state of the switch 3 is off, the calculation unit 64 determines that the secondary-side circuit connected to the switch 3 has no voltage.
演算部６４は、表示画面制御処理６４１として、開閉器３がそのオンオフに関する操作命令を受け付けた後、命令実行の前に、操作後の当該受変電設備２の回路状態を演算して推定し、推定結果を表示部６３に表示する。そして、演算部６４は、表示部６３に受け付けた操作命令を実行して良いか否かの確認画面を表示させた後に、ユーザに命令を実行するか否かを選択させ、命令実行が選択された場合は命令実行する。 The arithmetic unit 64 calculates and estimates the circuit state of the power receiving and transforming facility 2 after the operation as the display screen control processing 641 after the switch 3 receives the operation command regarding the ON / OFF of the switch 3 before executing the command, The estimation result is displayed on the display unit 63.
