Description

本発明は、監視制御システムに接続されて設置されている電気所の遠隔監視制御装置取替時の監視制御方法及び監視制御システムに関するものである。   The present invention relates to a supervisory control method and supervisory control system for replacing a remote supervisory control device of an electric station installed connected to the supervisory control system.

従来、電気所に設置している遠隔監視制御装置（データ伝送装置を含む）は、経年による劣化等の理由により取り替えなければならないものであるが、その手段としては、現地遠隔監視制御装置の新旧切替を電気所のエリア毎に数回に分けて実施している。遠隔監視制御を行う上位システムでは、その都度、対応するポジションの新旧切替のためのデータベース切替を行っている。例えば、図１に示すように、電気所の監視制御システム１には、モデム２を介してモデム３付きの遠隔監視制御装置（子局ＴＣ）４が接続されている（Ａポジション、Ａ−００１）。この遠隔監視制御装置（子局ＴＣ）４は経年により取り替えるべき旧い遠隔監視制御装置である。また、前記監視制御システム１には、モデム５を介してモデム６付きの遠隔監視制御装置（子局ＴＣ）７が接続されている（Ｂポジション、Ｂ−００１）。この遠隔監視制御装置（子局ＴＣ）７は新たに設置する新規の遠隔監視制御装置である。これらの遠隔監視制御装置（子局ＴＣ）４及び遠隔監視制御装置（子局ＴＣ）７には制御ケーブル８を介して遮断機９が接続されている。また、前記監視制御システム１の画面１０には、送電線１１、変圧器１２、受電部１３等の機器シンボル１４が表示されている。   Conventionally, remote monitoring and control devices (including data transmission devices) installed at electrical stations must be replaced for reasons such as deterioration over time. Switching is carried out in several times for each area of the electric station. In each host system that performs remote monitoring control, the database is switched for switching between the new and old positions. For example, as shown in FIG. 1, a remote monitoring control device (slave station TC) 4 with a modem 3 is connected to a monitoring control system 1 at an electric station via a modem 2 (A position, A-001). ). This remote monitoring control device (slave station TC) 4 is an old remote monitoring control device that should be replaced over time. Further, a remote monitoring control device (slave station TC) 7 with a modem 6 is connected to the monitoring control system 1 via a modem 5 (B position, B-001). This remote monitoring control device (slave station TC) 7 is a new remote monitoring control device to be newly installed. A breaker 9 is connected to the remote monitoring control device (slave station TC) 4 and the remote monitoring control device (slave station TC) 7 via a control cable 8. In addition, on the screen 10 of the monitoring control system 1, device symbols 14 such as a power transmission line 11, a transformer 12, and a power receiving unit 13 are displayed.

しかして、従来の遠隔監視制御装置（子局ＴＣ）４、７の取替時には、新旧の遠隔監視制御装置（子局ＴＣ）４、７に対し、図２（ａ）（ｂ）（ｃ）に示すように、あらかじめ同じ電気所の２画面を用意し、新旧のポジション情報をデータベースで定義する仕組みとなっていた。この場合、１つの電気所を２画面で監視することとなり、また、現地側の新旧の切替に対応して、新画面での監視範囲、旧画面での監視範囲の変更を、運転員が判断しなければならず、誤認するおそれがあった。   Thus, when the conventional remote monitoring and control device (slave station TC) 4 and 7 is replaced, the old and new remote monitoring and control devices (slave station TC) 4 and 7 are compared with FIGS. 2 (a), 2 (b), and 2 (c). As shown in Fig. 2, two screens of the same electric station are prepared in advance, and the new and old position information is defined in a database. In this case, one electric station will be monitored on two screens, and the operator will decide whether to change the monitoring range on the new screen or the monitoring range on the old screen in response to switching between the new and old on the local side. There was a risk of misunderstanding.

さらに、近年は、電気的接続状態をデータベース化し、電気所画面上で充電中／停電中の状態表示を色分けで行う技術が取り入れられており、図２に示す１つの電気所を２画面で監視するデータの作り方はできなくなり、図３に示すように、電気所のエリア毎に数回に分けて実施する現地遠隔監視制御装置（子局ＴＣ）４、７の新旧切替の都度、遠隔監視制御を行う上位システムにおいては、対応するポジションの新旧切替のため、ひとくくりのデータベースの切替を行っていた。この際のデータベースの切替回数例の一例を図４に示す。すなわち、画面の１つの機器シンボル１４に対し、１つのポジションに紐付けしているものであり、図示の例では、６つの断面に分離して、６回のデータベースの切替回数を必要としていたものである。この場合、各断面における機器シンボル１４は色分けにより区分表示されているものである。   Furthermore, in recent years, a technology has been introduced in which the electrical connection status is made into a database, and the status display during charging / power failure is displayed in different colors on the electrical station screen. One electrical site shown in FIG. 2 is monitored on two screens. As shown in Fig. 3, the remote monitoring and control system (slave station TC) 4 and 7 is switched every time, as shown in Fig. 3. In the host system that performs, the entire database was switched in order to switch the corresponding position between old and new. An example of the number of times of database switching at this time is shown in FIG. That is, one device symbol 14 on the screen is linked to one position, and in the example shown in the figure, it is divided into six sections and requires six database switching times. It is. In this case, the device symbol 14 in each cross section is displayed in a classified manner by color coding.

従来、遠隔監視制御装置の取替を行う場合、新しい遠隔監視制御装置を据えておいてケーブルの切替で部分的に切替作業を行っている。すなわち、全部を一度に切替えることができないので、部分的に停電範囲を設定しながら順次全体を取り替えているものである。この際、図３に示すように、一画面で表示する方法においても、例えば、６つの断面に分離する必要があり、各画面毎にデータベースを作成しなければならず、データベース切替が多数回になってしまうという第一の問題がある。これは、６つの切替断面を必要とすることであり、費用がかかるものである。   Conventionally, when a remote monitoring control device is replaced, a new remote monitoring control device is installed and a switching operation is partially performed by switching a cable. That is, since the whole cannot be switched at once, the whole is sequentially replaced while partially setting the power failure range. At this time, as shown in FIG. 3, even in the method of displaying on one screen, for example, it is necessary to divide into six sections, a database must be created for each screen, and database switching is performed many times. The first problem is that it becomes. This requires six switching sections and is expensive.

つぎに、予め決められた切替の順番を容易に変更することができず、制約を生じるという点が第二の問題点である。すなわち、データベースの切替は、予め決められた切替の順番に従い時系列で作成されている。そのため、なんらかの要因で切替順番が入れ替わる場合、新しい順番のデータベースを作り直し、事前の確認試験を実施した後、新しいデータベースの切替を実施しなければならない。また、再度データベースを作り直して再試験する必要が生じる。   Next, the second problem is that a predetermined switching order cannot be easily changed and a restriction occurs. That is, the database switching is created in time series according to a predetermined switching order. For this reason, when the switching order is switched due to some reason, it is necessary to re-create a database in a new order, perform a prior confirmation test, and then switch to a new database. In addition, the database needs to be recreated and retested.

請求項１記載の発明は、電気所の監視制御システムに接続されて設置されている遠隔監視制御装置の取替時に、旧遠隔監視制御装置と新遠隔監視制御装置とを運用者によるケーブル切替により切替えて監視制御システムで機器シンボルを一画面に表示し、仮想的に設けたソフトウェアスイッチを運用者が新旧切替操作をすることで現地制御ケーブル切替に対応できるように監視制御装置画面シンボルのポジションリンクの２重化をするようにしたものである。   According to the first aspect of the present invention, when the remote monitoring control device connected to the monitoring control system of the electric station is replaced, the old remote monitoring control device and the new remote monitoring control device are switched by the cable switching by the operator. Switch and display the device symbol on the monitoring control system on one screen, and the position link of the monitoring control device screen symbol so that the operator can respond to the local control cable switching by operating the old and new switching software switch Is to be duplicated.

請求項２記載の発明は、旧遠隔監視制御装置と新遠隔監視制御装置とを運用者によるケーブル切替により切替えて監視制御システムで機器シンボルを一画面に表示する表示手段と、仮想的に設けたソフトウェアスイッチを運用者が新旧切替操作をすることで現地制御ケーブル切替に対応できるように監視制御装置画面シンボルのポジションリンクの２重化をする２重化手段とを備えた電気所における遠隔監視制御装置取替のための監視制御システムである。   The invention according to claim 2 is provided virtually with display means for switching the old remote monitoring control device and the new remote monitoring control device by cable switching by the operator and displaying the device symbol on one screen by the monitoring control system. Remote monitoring and control at electrical stations with duplex means for duplicating the position link of the monitor control device screen symbol so that the operator can switch the local control cable by switching the software switch between old and new This is a supervisory control system for device replacement.

請求項１記載の発明によれば、一つの機器シンボルに対し、２つの異なるポジションを予めデータベースで定義することができ、運用者により、容易にどちらかを選択できる仕組みを持たせることでデータベース切替を一度に行うことができるものである。また、２つの異なるポジション切替は、仮想的に設けたソフトウェアスイッチを運用者が新旧切替操作をすることで行い得るので、別のハードウェアを必要としない仕組みとすることができる。したがって、順番の入れ替わり等があっても、現地の新旧遠隔監視制御装置に取り込まれる制御ケーブルの切替を実施したポジションのみを、運用者が通常の機器操作と同様な操作で切替えることができ、データベースの都度切替を不要としたものである。   According to the first aspect of the present invention, two different positions can be defined in advance in a database for one device symbol, and database switching is provided by providing a mechanism that can be easily selected by the operator. Can be done at once. In addition, since the two different positions can be switched by the operator performing a new / old switching operation on the software switch that is virtually provided, a mechanism that does not require separate hardware can be achieved. Therefore, even if there is a change in order, the operator can switch only the position where the control cable imported to the local old and new remote monitoring and control device has been switched by the same operation as the normal device operation. Switching is not necessary each time.

請求項２記載の発明によれば、監視制御装置画面シンボルのポジションリンクの２重化をする２重化手段により、一つの機器シンボルに対し、２つの異なるポジションを予めデータベースで定義することができ、運用者により、容易にどちらかを選択できる仕組みを持たせることでデータベース切替を一度に行うことができるものである。また、２つの異なるポジション切替は、監視制御装置画面シンボルのポジションリンクの２重化をする２重化手段を備えていることにより、仮想的に設けたソフトウェアスイッチを運用者が新旧切替操作をすることで行い得るので、別のハードウェアを必要としない仕組みとすることができる。したがって、順番の入れ替わり等があっても、現地の新旧遠隔監視制御装置に取り込まれる制御ケーブルの切替を実施したポジションのみを、運用者が通常の機器操作と同様な操作で切替ることができ、データベースの都度切替を不要としたものである。   According to the second aspect of the present invention, two different positions can be defined in advance in the database for one device symbol by the duplication means for duplicating the position link of the monitor control device screen symbol. By providing a mechanism that allows the operator to easily select either one, the database can be switched at a time. In addition, since the two different position switching is provided with a duplicating means for duplicating the position link of the monitor control device screen symbol, the operator switches the old and new software switches provided virtually. Therefore, a mechanism that does not require separate hardware can be obtained. Therefore, even if there is a change in order, the operator can switch only the position where the control cable switched to the local old and new remote monitoring and control device is switched by the same operation as the normal device operation, Switching between databases is unnecessary.

本発明の実施の態様を図５に基いて説明する。基本的な構成は、前述の従来例として説明した図１に示したものと同様である。まず、電気所の監視制御システム１５には、モデム１６を介してモデム１７付きの遠隔監視制御装置（子局ＴＣ）１８が接続されている（Ａポジション、Ａ−００１）。この遠隔監視制御装置（子局ＴＣ）１８は経年により取り替えるべき旧い遠隔監視制御装置である。また、前記監視制御システム１５には、モデム１９を介してモデム２０付きの遠隔監視制御装置（子局ＴＣ）２１が接続されている（Ｂポジション、Ｂ−００１）。この遠隔監視制御装置（子局ＴＣ）２１は新たに設置する新規の遠隔監視制御装置である。これらの遠隔監視制御装置（子局ＴＣ）１８及び遠隔監視制御装置（子局ＴＣ）２１には制御ケーブル２２を介して遮断機２３が接続されている。また、前記監視制御システム１５の画面２４には、送電線２５、変圧器２６、受電部２７等の機器シンボル２８が表示されている。従って、前記監視制御システム１５の前記画面２４は、旧遠隔監視制御装置１８と新遠隔監視制御装置２１とを運用者によるケーブル切替により切替えて機器シンボル２８を一画面に表示する表示手段となるものである。しかして、前記モデム１６、１９と前記機器シンボル２８との間には、仮想的に設けたソフトウェアスイッチ２９が介挿されている。このソフトウェアスイッチ２９を設けることにより、現地制御ケーブル切替に対応できるように監視制御装置画面シンボルのポジションリンクの２重化をする２重化手段が構成されるものである。   An embodiment of the present invention will be described with reference to FIG. The basic configuration is the same as that shown in FIG. 1 described as the conventional example. First, a remote monitoring control device (slave station TC) 18 with a modem 17 is connected to a monitoring control system 15 at an electric station via a modem 16 (A position, A-001). This remote monitoring control device (slave station TC) 18 is an old remote monitoring control device that should be replaced over time. In addition, a remote monitoring control device (slave station TC) 21 with a modem 20 is connected to the monitoring control system 15 via a modem 19 (B position, B-001). This remote monitoring control device (slave station TC) 21 is a new remote monitoring control device to be newly installed. A breaker 23 is connected to the remote monitoring control device (slave station TC) 18 and the remote monitoring control device (slave station TC) 21 via a control cable 22. Further, on the screen 24 of the monitoring control system 15, device symbols 28 such as a power transmission line 25, a transformer 26, and a power receiving unit 27 are displayed. Therefore, the screen 24 of the monitoring control system 15 serves as a display means for switching the old remote monitoring control device 18 and the new remote monitoring control device 21 by cable switching by the operator and displaying the device symbol 28 on one screen. It is. Thus, a virtually installed software switch 29 is interposed between the modems 16 and 19 and the device symbol 28. By providing this software switch 29, a duplicating means for duplicating the position link of the monitoring control apparatus screen symbol is constructed so as to be able to cope with the on-site control cable switching.

このような構成において、遠隔監視制御装置（子局ＴＣ）１８、２１の取替時には、どういう順番で作業しようとも、遮断機２３による制御ケーブル２２を切替えたところだけ新しい遠隔監視制御装置（子局ＴＣ）２１を選べるようにソフトウェアスイッチ２９を切替えるように操作してやればよい。すなわち、本実施の態様における監視制御システム１５では、通常画面２４の一つの機器シンボル２８に対し、１つのポジションで紐付けされているが、新・旧２つのポジションに対し、どちらか一つを運用者が選択できる仕組みとなっており、選ばれたポジションと画面の機器シンボル２８とを紐付けする構成となっている。これにより、順番の入れ替わりが等があっても、新旧の切替を実施したポジションのみを運用者で切替えることで対応でき、データベースの都度切替が不要となっているものである。   In such a configuration, when the remote monitoring control device (slave station TC) 18 and 21 is replaced, a new remote monitoring control device (slave station) is changed only when the control cable 22 is switched by the circuit breaker 23 regardless of the order. (TC) The software switch 29 may be switched so that 21 can be selected. That is, in the monitoring control system 15 according to the present embodiment, one device symbol 28 on the normal screen 24 is linked at one position, but one of the new and old two positions is linked. The system allows the operator to select and links the selected position to the device symbol 28 on the screen. As a result, even if there is a change in order, etc., it can be handled by switching only the positions where the old and new switching have been performed by the operator, and switching is not required each time the database is switched.

このように本実施の態様によれば、一つの機器シンボルに対し、２つの異なるポジションを予めデータベースで定義することができ、運用者により、容易にどちらかを選択できる仕組みを持たせることでデータベース切替を一度に行うことができるものである。また、２つの異なるポジション切替は、仮想的に設けたソフトウェアスイッチを運用者が新旧切替操作をすることで行い得るので、別のハードウェアを必要としない仕組みとすることができる。したがって、順番の入れ替わり等があっても、現地の新旧遠隔監視制御装置に取り込まれる制御ケーブルの切替を実施したポジションのみを、運用者が通常の機器操作と同様な操作で切替えることができ、データベースの都度切替を不要としたものである。   As described above, according to the present embodiment, two different positions can be defined in advance in the database for one device symbol, and the database can be provided by providing a mechanism that can be easily selected by the operator. Switching can be performed at a time. In addition, since the two different positions can be switched by the operator performing a new / old switching operation on the software switch that is virtually provided, a mechanism that does not require separate hardware can be achieved. Therefore, even if there is a change in order, the operator can switch only the position where the control cable imported to the local old and new remote monitoring and control device has been switched by the same operation as the normal device operation. Switching is not necessary each time.
