Description

監視制御システムおよび操作監視端末Monitoring control system and operation monitoring terminal
　本発明の実施形態は、監視制御システムおよび操作監視端末に関する。 Embodiments of the present invention relate to a monitoring control system and an operation monitoring terminal.
　従来、変圧器に設置される負荷時タップ切換器（以下、ＬＴＣという）のタップを遠隔より制御する場合、操作員によるタップ切換操作と、実際にタップが切り換わる時間差により、操作員が現在のタップの位置や状況を正しく認識することができなかった。そのため、操作員が連続してタップ切換操作を行ってしまうことで、切換開閉器に負担を掛け、ＬＴＣを故障させるリスクが内在していた。 Conventionally, when a tap of a load tap changer (hereinafter referred to as LTC) installed in a transformer is controlled remotely, the operator is present due to the time difference between the tap change operation by the operator and the actual tap change. The position and situation of the tap could not be recognized correctly. For this reason, there is an inherent risk that the operator will perform the tap switching operation continuously, placing a burden on the switching switch and causing the LTC to fail.

　図６は、タップ切換操作のフローチャートである。 (Function)
FIG. 6 is a flowchart of the tap switching operation.
　制御機器（ＬＴＣ付変圧器）４１は、１系ＬＴＣ付変圧器４１１と２系ＬＴＣ付変圧器４１２を備え、タップ切換動作は、「１系単独」、「２系単独」あるいは「並列」で行える。「並列」の場合、１系ＬＴＣ付変圧器４１１と２系ＬＴＣ付変圧器４１２のタップが一致しているとき、両方のタップ切換動作を、どちらか一方のタップ切換操作で行う。 The control device (LTC-equipped transformer) 41 includes a 1-system LTC-equipped transformer 411 and a 2-system LTC-equipped transformer 412, and the tap switching operation is “1 system alone”, “2 systems alone”, or “parallel”. Yes. In the case of “parallel”, when the taps of the 1-system LTC-equipped transformer 411 and the 2-system LTC-equipped transformer 412 coincide, both tap switching operations are performed by either one of the tap switching operations.
（１系単独タップ切換操作）
　まず、１系タップ切換操作を操作部１１３が受ける（Ｓ１１）と、ＴＲ運転モード（Ｓ２１）によってその後のフローが異なる。ＴＲ運転モード（Ｓ２１）は、あらかじめ設定しておくものである。ＴＲとは、変圧器のことを意味する。 (Single system single tap switching operation)
First, when the operation unit 113 receives a 1-system tap switching operation (S11), the subsequent flow differs depending on the TR operation mode (S21). The TR operation mode (S21) is set in advance. TR means a transformer.
　ＴＲ運転モード（Ｓ２１）が「単独」の場合、判断部３１３は、１系制御モードが手動かを判断する（Ｓ４１）。自動制御モードの場合は、手動制御モードに切り替えてからタップ切換操作を行わせるためである。自動制御モードとは、例えば自動電圧調整器のようなＬＴＣタップ切換を自動で行う装置と併用する際、その自動で行う装置で制御をするモードを指す。１系制御モードが手動ではない場合（Ｓ４１でＮｏ）、制御機器に対しての切換指令は出力されない。つまり、１系タップ切換動作は起こらない。 When the TR operation mode (S21) is “single”, the determination unit 313 determines whether the 1-system control mode is manual (S41). This is because in the automatic control mode, the tap switching operation is performed after switching to the manual control mode. The automatic control mode refers to a mode in which control is performed by a device that automatically performs LTC tap switching such as an automatic voltage regulator when used in combination with a device that automatically performs LTC tap switching. When the 1-system control mode is not manual (No in S41), the switching command for the control device is not output. That is, the 1-system tap switching operation does not occur.
　１系制御モードが手動である場合（Ｓ４１でＹｅｓ）、判断部３１３は、１系タップ切換中ではないかを判断する（Ｓ５１）。１系タップ切換中の場合（Ｓ５１でＮｏ）、制御機器に対しての切換指令は出力されない。 If the 1-system control mode is manual (Yes in S41), the determination unit 313 determines whether the 1-system tap is being switched (S51). When the 1-system tap is being switched (No in S51), the switching command to the control device is not output.
　１系タップ切換中ではない場合（Ｓ５１でＹｅｓ）、判断部３１３は、１系タップ切換が渋滞中ではないかを判断する（Ｓ６１）。タップ切換が渋滞中とは、受けたタップ切換操作が完了していない状態を意味する。１系タップ切換が渋滞中の場合（Ｓ６１でＮｏ）、制御機器に対しての切換指令は出力されない。 If the 1-system tap is not being switched (Yes in S51), the determination unit 313 determines whether the 1-system tap is being switched (S61). “Tap switching is in a traffic jam” means that the received tap switching operation has not been completed. When the 1-system tap switching is in a traffic jam (No in S61), the switching command for the control device is not output.
　１系タップ切換が渋滞中ではない場合（Ｓ６１でＹｅｓ）、判断部３１３は、前回の１系タップ切換から一定時間が経過したかを判断する（Ｓ７１）。一定時間の設定は、ユーザが選択できる。前回の１系タップ切換から一定時間が経過していない場合（Ｓ７１でＮｏ）、制御機器に対しての切換指令は出力されない。 When the 1-system tap switching is not in a traffic jam (Yes in S61), the determination unit 313 determines whether a certain time has elapsed since the previous 1-system tap switching (S71). The user can select the fixed time setting. If the predetermined time has not elapsed since the previous 1-system tap switching (No in S71), the switching command to the control device is not output.
　前回の１系タップ切換から一定時間が経過した場合（Ｓ７１でＹｅｓ）、判断部３１３は、通信部３１５を介して制御機器（ＬＴＣ付変圧器）４１に対してタップ切換指令を出力し、タップ切換動作部４１２は、ＬＴＣ付変圧器（１系）４１１のタップ切換動作を開始する（Ｓ８１）。 When a certain time has elapsed since the previous 1-system tap switching (Yes in S71), the determination unit 313 outputs a tap switching command to the control device (transformer with LTC) 41 via the communication unit 315, and taps. The switching operation unit 412 starts the tap switching operation of the LTC transformer (first system) 411 (S81).
　その後、タップ切換回数積算部２１３が１系ＬＴＣタップ切換回数を積算し、表示部１１２が表示させる（Ｓ９１）。ただし、タップ切換回数の積算・表示は必ずしもシステムに必要なものではない。 After that, the tap switching number integrating unit 213 integrates the number of 1-system LTC tap switching, and the display unit 112 displays it (S91). However, the integration / display of the number of tap switching is not necessarily required for the system.
（２系単独タップ切換操作）
　１系単独タップ切換操作と同様に、２系単独タップ切換操作を行う。 (2 system single tap switching operation)
Similar to the 1-system single tap switching operation, the 2-system single tap switching operation is performed.
　まず、２系タップ切換操作を操作部１１３が受ける（Ｓ１２）と、ＴＲ運転モード（Ｓ２２）によってその後のフローが異なる。なお、ＴＲ運転モード（Ｓ２２）は、あらかじめ設定しておくものである。 First, when the operation unit 113 receives a 2-system tap switching operation (S12), the subsequent flow differs depending on the TR operation mode (S22). The TR operation mode (S22) is set in advance.
　ＴＲ運転モード（Ｓ２２）が「単独」の場合、判断部３１３は、２系制御モードが手動かを判断する（Ｓ４２）。２系制御モードが手動ではない場合（Ｓ４２でＮｏ）、制御機器に対しての切換指令は出力されない。 When the TR operation mode (S22) is “single”, the determination unit 313 determines whether the 2 system control mode is manual (S42). When the 2 system control mode is not manual (No in S42), the switching command to the control device is not output.
　２系制御モードが手動である場合（Ｓ４２でＹｅｓ）、判断部３１３は、２系タップ切換中ではないかを判断する（Ｓ５２）。２系タップ切換中の場合（Ｓ５２でＮｏ）、制御機器に対しての切換指令は出力されない。 When the second system control mode is manual (Yes in S42), the determination unit 313 determines whether the second system tap is being switched (S52). When the 2 system tap is being switched (No in S52), the switching command to the control device is not output.
　２系タップ切換中ではない場合（Ｓ５２でＹｅｓ）、判断部３１３は、２系タップ切換が渋滞中ではないかを判断する（Ｓ６２）。２系タップ切換が渋滞中の場合（Ｓ６２でＮｏ）、制御機器に対しての切換指令は出力されない。 If the 2 system tap switching is not in progress (Yes in S52), the determination unit 313 determines whether the 2 system tap switching is in a traffic jam (S62). When the 2 system tap switching is in a traffic jam (No in S62), the switching command to the control device is not output.
　２系タップ切換が渋滞中ではない場合（Ｓ６２でＹｅｓ）、判断部３１３は、前回の２系タップ切換から一定時間が経過したかを判断する（Ｓ７２）。一定時間が経過していない場合（Ｓ７２でＮｏ）、制御機器に対しての切換指令は出力されない。 If the 2 system tap switching is not in a traffic jam (Yes in S62), the determination unit 313 determines whether a certain time has elapsed since the previous 2 system tap switching (S72). If the predetermined time has not elapsed (No in S72), the switching command for the control device is not output.
　前回の２系タップ切換から一定時間が経過した場合（Ｓ７２でＹｅｓ）、判断部３１３は、通信部３１５を介して制御機器（ＬＴＣ付変圧器）４１に対してタップ切換指令を出力し、タップ切換動作部４１２は、ＬＴＣ付変圧器（２系）４１２のタップ切換動作を開始する（Ｓ８２）。 When a certain time has elapsed since the last two-system tap switching (Yes in S72), the determination unit 313 outputs a tap switching command to the control device (LTC transformer) 41 via the communication unit 315, and taps. The switching operation unit 412 starts the tap switching operation of the LTC transformer (second system) 412 (S82).
その後、タップ切換回数積算部２１３が２系ＬＴＣタップ切換回数を積算し、表示部１１２が表示させる（Ｓ９２）。タップ切換回数の積算・表示は必ずしもシステムに必要なものではない。 Thereafter, the tap switching number integrating unit 213 integrates the number of 2-system LTC tap switching, and the display unit 112 displays it (S92). Accumulation / display of the number of tap switching is not necessarily required for the system.
（並列タップ切換操作）
　並列タップ切換操作とは、１系変圧器と２系変圧器のタップが一致しているとき、両方のタップ切換動作を、どちらか一方のタップ切換操作で行うことである。 (Parallel tap switching operation)
The parallel tap switching operation is to perform both tap switching operations by one of the tap switching operations when the taps of the system 1 transformer and the system 2 transformer match.
　並列タップ切換操作を行うときは、操作部１１３が１系タップ切換操作を受け（Ｓ１１）、ＴＲ運転モード（Ｓ２１）が「１系並列主」のとき、あるいは、２系タップ切換操作を受け（Ｓ１２）、ＴＲ運転モード（Ｓ２２）が「２系並列主」のときである。 When performing a parallel tap switching operation, the operation unit 113 receives a 1-system tap switching operation (S11), and when the TR operation mode (S21) is "1 system parallel main" or a 2-system tap switching operation ( S12), when the TR operation mode (S22) is “2-system parallel main”.
　そのとき判断部３１３は、１系LTC付変圧器と２系LTC付変圧器のタップが一致しているかを判断する（Ｓ３３）。タップが一致していない場合（Ｓ３３でＮｏ）、制御機器に対しての切換指令は出力されない。 At that time, the determination unit 313 determines whether the taps of the 1-system LTC transformer and the 2-system LTC transformer match (S33). If the taps do not match (No in S33), the switching command for the control device is not output.
　タップが一致している場合（Ｓ３３でＹｅｓ）、判断部３１３は、１系、２系制御モードが手動かを判断する（Ｓ４３）。１系、２系制御モードがどちらか一方でも手動ではない場合（Ｓ４３でＮｏ）、制御機器に対しての切換指令は出力されない。 If the taps match (Yes in S33), the determination unit 313 determines whether the 1-system and 2-system control mode is manual (S43). When either the 1-system or 2-system control mode is not manual (No in S43), the switching command for the control device is not output.
　１系、２系制御モードがどちらも手動である場合（Ｓ４３でＹｅｓ）、判断部３１３は、１系、２系タップが切換中ではないかを判断する（Ｓ５３）。１系、２系タップのどちらか一方でも切換中の場合（Ｓ５３でＮｏ）、制御機器に対しての切換指令は出力されない。 When both the 1-system and 2-system control modes are manual (Yes in S43), the determination unit 313 determines whether the 1-system and 2-system taps are being switched (S53). When either one of the 1-system and 2-system taps is being switched (No in S53), the switching command to the control device is not output.
　１系、２系タップのどちらも切換中ではない場合（Ｓ５３でＹｅｓ）、判断部３１３は、１系、２系タップ切換が渋滞中ではないかを判断する（Ｓ６３）。１系、２系タップの切換がどちらか一方でも渋滞中の場合（Ｓ６３でＮｏ）、制御機器に対しての切換指令は出力されない。 If neither the 1-system or 2-system tap is being switched (Yes in S53), the determination unit 313 determines whether the 1-system, 2-system tap switching is in a traffic jam (S63). When the switching between the 1-system and 2-system taps is in a traffic jam (No in S63), the switching command for the control device is not output.
　１系、２系タップの切換がどちらも渋滞中ではない場合（Ｓ６３でＹｅｓ）、判断部３１３は、前回の１系または２系タップ切換から一定時間が経過したかを判断する（Ｓ７３）。一定時間が経過していない場合（Ｓ７３でＮｏ）、制御機器に対しての切換指令は出力されない。 If neither the 1-system or 2-system tap switching is in a traffic jam (Yes in S63), the determination unit 313 determines whether a predetermined time has elapsed since the previous 1-system or 2-system tap switching (S73). If the predetermined time has not elapsed (No in S73), the switching command for the control device is not output.
　前回の１系または２系タップ切換から一定時間が経過した場合（Ｓ７３でＹｅｓ）、判断部３１３は、通信部３１５を介して制御機器（ＬＴＣ付変圧器）４１に対してタップ切換指令を出力し、タップ切換動作部４１２は、ＬＴＣ付変圧器（１系）４１１とＬＴＣ付変圧器（２系）４１２のタップ切換動作を開始する（Ｓ８３）。 When a predetermined time has elapsed since the previous 1-system or 2-system tap switching (Yes in S73), the determination unit 313 outputs a tap switching command to the control device (transformer with LTC) 41 via the communication unit 315. Then, the tap switching operation unit 412 starts the tap switching operation of the transformer with LTC (first system) 411 and the transformer with LTC (second system) 412 (S83).
　その後、タップ切換回数積算部２１３が１系と２系ＬＴＣタップ切換回数をそれぞれ積算し、表示部１１２が表示させる（Ｓ９３）。タップ切換回数の積算・表示は必ずしもシステムに必要なものではない。 Thereafter, the tap switching frequency integration unit 213 integrates the 1st system and 2nd system LTC tap switching frequency, and the display unit 112 displays them (S93). Accumulation / display of the number of tap switching is not necessarily required for the system.
　以上のように、操作員によるタップ切換操作が行われても、種々の条件（Ｓ２１～Ｓ７３）が揃わないと、制御機器に対しての切換指令は出力されない。 As described above, even if the tap switching operation is performed by the operator, the switching command to the control device is not output unless various conditions (S21 to S73) are met.
（効果）
　操作員によるタップ切換操作が行われても、種々の条件が揃わないと制御機器に対しての切換指令は出力されないインタロックにより、連続してタップ切換操作を行えなくなるため、連続操作によるLTC付変圧器故障のリスクを低減させることが可能となる。また、遠隔操作員はＬＴＣタップ切換操作が正常に行われていることを確認できる。 (effect)
Even if the tap switching operation is performed by the operator, if various conditions are not met, the switching command to the control device is not output, so the tap switching operation cannot be performed continuously. The risk of transformer failure can be reduced. Further, the remote operator can confirm that the LTC tap switching operation is normally performed.
　なお、制御機器に対しての切換指令を出力するかの判断（Ｓ３３～Ｓ７３）を行う判断部３１３は、図２では制御子局３１にあるが、制御親局２１や操作監視端末１１にあってもよい。 The determination unit 313 for determining whether to output a switching command to the control device (S33 to S73) is located in the control slave station 31 in FIG. May be.
　なお、本実施例は、制御親局と、複数または単一の制御子局が伝送で接続されたシステム構成全てに適用可能なもので、装置の台数や、伝送の種類に制約を受けるものではない。 This embodiment can be applied to all system configurations in which a control master station and a plurality of or single control slave stations are connected by transmission, and is not limited by the number of devices or the type of transmission. Absent.

（構成）
　図７は、監視制御システム２を含む装置構成図である。 (Second Embodiment)
(Constitution)
FIG. 7 is an apparatus configuration diagram including the monitoring control system 2.
　第１の実施形態の装置構成図である図１と、第２の実施形態の装置構成図である図７が異なる点は、ＬＴＣ制御専用操作端末５１とＬＴＣ制御専用コントローラ６１を付加した点であり、このＬＴＣ制御専用操作端末５１とＬＴＣ制御専用コントローラ６１以外は第１の実施形態と同じであるので、同一部分には同一符号を付して詳細な説明は省略する。 The difference between FIG. 1 which is the device configuration diagram of the first embodiment and FIG. 7 which is the device configuration diagram of the second embodiment is that an LTC control dedicated operation terminal 51 and an LTC control dedicated controller 61 are added. Yes, except for the LTC control dedicated operation terminal 51 and the LTC control dedicated controller 61, the second embodiment is the same as the first embodiment.
　ＬＴＣ制御専用操作端末５１とＬＴＣ制御専用コントローラ６１は、ＬＴＣ制御専用の機器であり、制御機器（ＬＴＣ付変圧器）４１の近傍に設置し、タップ切換操作を行えるようにする。 The LTC control dedicated operation terminal 51 and the LTC control dedicated controller 61 are devices dedicated to LTC control, and are installed in the vicinity of the control device (transformer with LTC) 41 so that a tap switching operation can be performed.
　第一の実施形態でタップ切換操作を行う端末である操作監視端末１１と制御親局２１と制御子局３１は、一般的に制御機器（ＬＴＣ付変圧器）４１から離れた場所に設置し、遠方からタップ切換操作を行えるようにする。 The operation monitoring terminal 11, the control master station 21, and the control slave station 31, which are terminals that perform the tap switching operation in the first embodiment, are generally installed in a place away from the control device (transformer with LTC) 41, Enable tap switching from a distance.
　制御機器（ＬＴＣ付変圧器）４１の近傍で、遠方から操作するかまたは直接操作するかの使い分けを行う。遠方から操作するとは、操作監視端末１１からタップ切換操作をすることを意味する。直接操作するとは、ＬＴＣ制御専用操作端末５１からタップ切換操作をすることを意味する。操作場所切換用のスイッチは、制御機器（ＬＴＣ付変圧器）４１の近傍に設置する。 In the vicinity of the control device (transformer with LTC) 41, it is selectively used whether to operate from a distance or directly. “Operating from a distance” means performing a tap switching operation from the operation monitoring terminal 11. Direct operation means performing a tap switching operation from the LTC control dedicated operation terminal 51. The switch for switching the operation place is installed in the vicinity of the control device (transformer with LTC) 41.
　ここで、制御機器（ＬＴＣ付変圧器）４１への接続は、図７のように制御子局３１から制御機器（ＬＴＣ付変圧器）４１に接点で接続されるだけでなく、ＬＴＣ制御専用コントローラ６１から制御機器（ＬＴＣ付変圧器）４１に接点で接続される。 Here, the connection to the control device (transformer with LTC) 41 is not only connected from the control slave station 31 to the control device (transformer with LTC) 41 by a contact as shown in FIG. 61 is connected to the control device (transformer with LTC) 41 through a contact.
　図８は、ＬＴＣ制御専用操作端末５１の機能構成を示す図である。ＬＴＣ制御専用操作端末５１は、操作監視端末１１と同様の機能を有するものとする。図２の操作監視端末１１の機能構成と同一部分には同一符号を付して詳細な説明は省略する。 FIG. 8 is a diagram showing a functional configuration of the LTC control dedicated operation terminal 51. It is assumed that the LTC control dedicated operation terminal 51 has the same function as the operation monitoring terminal 11. The same parts as those in the functional configuration of the operation monitoring terminal 11 in FIG.
　第二の操作部１１６の機能は、操作部１１３と同様である。 The function of the second operation unit 116 is the same as that of the operation unit 113.

It is assumed that the LTC control dedicated controller 61 has the functions of the control master station 21 and the control slave station 31. The same components as those of the functional configuration 21 of the control master station in FIG. 3 and the control slave station 31 in FIG. 4 are denoted by the same reference numerals, and detailed description thereof is omitted.
　第二の判断部３１６の機能は、判断部３１３と同様である。 The function of the second determination unit 316 is the same as that of the determination unit 313.
（作用）
　図１０は、タップ切換操作のフローチャートである。 (Function)
FIG. 10 is a flowchart of the tap switching operation.
　第１の実施形態のタップ切換操作のフローチャートである図６と、第２の実施形態のタップ切換操作のフローチャートである図１０が異なる点は、Ｓ１１１～Ｓ１２４を付加した点であり、これら以外は第１の実施形態と同じであるので、同一ステップには同一符号を付して詳細な説明は省略する。 The difference between FIG. 6 which is the flowchart of the tap switching operation of the first embodiment and FIG. 10 which is the flowchart of the tap switching operation of the second embodiment is that S111 to S124 are added. Since it is the same as 1st Embodiment, the same code | symbol is attached | subjected to the same step and detailed description is abbreviate | omitted.
　Ｓ１１１～Ｓ１２４は、１系タップ切換操作、２系タップ切換操作がそれぞれ操作監視端末１１で行われたか（以下「遠方」とする）、ＬＴＣ制御専用操作端末５１で行われたか（以下「直接」とする）を判断するステップである。 In S111 to S124, whether the 1-system tap switching operation and the 2-system tap switching operation were each performed on the operation monitoring terminal 11 (hereinafter referred to as “distant”) or the LTC control dedicated operation terminal 51 (hereinafter referred to as “direct”). It is a step to judge.
　「遠方」で１系タップ切換操作が行われた場合（Ｓ１１１）、操作場所が遠方かを判断する（Ｓ１１３）。遠方の場合（Ｓ１１３でＹｅｓ）、「遠方」の状態を識別する。 When the 1-system tap switching operation is performed in “far” (S111), it is determined whether the operation location is far (S113). If far away (Yes in S113), the “far” state is identified.
　同様に、「直接」で１系タップ切換操作が行われた場合（Ｓ１１２）、操作場所が直接かを判断する（Ｓ１１４）。直接の場合（Ｓ１１４でＹｅｓ）、「直接」の状態を識別する。 Similarly, when the 1-system tap switching operation is performed “directly” (S112), it is determined whether the operation location is direct (S114). In the case of direct (Yes in S114), the “direct” state is identified.
　同様に、「遠方」で２系タップ切換操作が行われた場合（Ｓ１２１）、操作場所が遠方かを判断する（Ｓ１２３）。遠方の場合（Ｓ１２３でＹｅｓ）、「遠方」の状態を識別する。 Similarly, when the 2 system tap switching operation is performed in “far” (S121), it is determined whether the operation place is far (S123). If far away (Yes in S123), the “far” state is identified.
