The standby operation of the server device will be described later.

[Operation of the maintenance function]
Details of the operation of the maintenance function will be described below with reference to the drawings.
FIG. 7 is a flowchart showing an example of the operation of the maintenance server device KSV of the first embodiment.
The maintenance interface function of the maintenance server device KSV (maintenance virtual HMI server system) acquires the update operation information REI from the maintenance console thin client NCT provided in each control station C (step S510). The maintenance interface function supplies the acquired update operation information REI to the maintenance function of the maintenance server device KSV (maintenance virtual server system) (step S520). The maintenance function acquires update operation information REI from the maintenance interface function (step S530). The maintenance function generates updated facility information CEI based on the acquired update operation information REI (step S540). The maintenance function supplies the generated updated facility information CEI to the monitoring control server device MSV and the system board server device CSV (step S570). The monitoring control server device MSV stores the acquired updated facility information CEI in the facility information storage unit EM (emergency facility information storage unit IF) included in the monitoring control server device MSV (step S580). The system board server device CSV stores the acquired updated equipment information CEI in the equipment information storage unit EM (emergency equipment information storage unit IF) included in the system board server device CSV (step S590).
The maintenance function stores the update facility information CEI in the monitoring control server apparatus MSV and the system board server apparatus CSV, and then supplies DB switching start information to the maintenance interface function (step S600). The maintenance interface function acquires DB switching start information from the maintenance function (step S610). The maintenance interface function transmits the acquired DB switching start information to the standby operation monitoring control server device MSV and the standby operation system board server device CSV (step S620). The maintenance interface function acquires, for example, information indicating the operation state of the monitoring control server device MSV and the system board server device CSV via the maintenance LAN. Further, the maintenance interface function transmits DB switching start information to the server device in standby operation based on the acquired information indicating the operation state of the monitoring control server device MSV and the system board server device CSV. In response to receiving the DB switching start information, the monitoring control server apparatus MSV switches the operation of the facility information storage unit EM (step S630). Specifically, the facility information storage unit EM included in the monitoring control server apparatus MSV performs operations of the regular facility information storage unit IU and the emergency facility information storage unit IF in response to receiving the DB switching start information. Switched. In addition, the system board server device CSV switches the operation of the facility information storage unit EM in response to receiving the DB switching start information. (Step S640). Specifically, the facility information storage unit EM included in the system board server device CSV performs operations of the regular facility information storage unit IU and the emergency facility information storage unit IF in response to receiving the DB switching start information. Switched. Accordingly, the facility information EI is equivalent in the plurality of monitoring control server devices MSV and the plurality of system board server devices CSV included in the centralized monitoring control system 1.

The centralized monitoring control system 1 of this embodiment is equivalent to the equipment information of the equipment EQ referred to by the server group 10 of each server base S by the maintenance function. In the present embodiment, one monitoring control server device operates as a regular operation and the remaining two devices operate as standbys. By always maintaining the equipment information of the three monitoring control server devices as 3 The equipment EQ can be monitored and controlled even if one of the two server bases S is changed to normal use.
A monitoring control system is arranged for each control station C. According to the centralized monitoring control system 1 of the present embodiment, the number of devices constituting the equipment information storage unit can be reduced compared to a configuration in which each has an equipment information storage unit. Therefore, it is possible to reduce the facility cost and the operation cost related to the device that stores the facility information EI.
Further, according to the centralized monitoring control system 1 of the present embodiment, the maintenance server device KSV updates the facility information EI of each monitoring control server device MSV and each system board server device CSV via the maintenance LAN.

The equipment cost and the operation cost related to the device for updating the system can be reduced.

[About synchronization between servers]
Here, the centralized monitoring control system 1 is configured to be able to monitor and control the substation T (equipment EQ) to be monitored and controlled by the three server sites S. In order for all of the monitoring control server devices MSV of the three server bases S to be able to monitor and control the equipment EQ of the centralized monitoring and control system 1, the equipment function EI of the equipment EQ to be monitored and controlled is maintained with the maintenance function, and In addition to synchronization (equivalent) by the maintenance interface function, it is preferable to synchronize (equivalent) information about the monitoring information MI. In this example, the monitoring control server device MSVA operates as a normal device (hereinafter referred to as a normal operation) during normal times, and the monitoring control server device MSVB and the monitoring control server device MSVC operate as standby devices (hereinafter referred to as a standby operation). The case will be described.
The supervisory control function of the supervisory control server device MSV (in this example, the supervisory control server device MSVA) that operates normally is the standby control server device MSV (in this example, the supervisory control server device MSVB, and the supervisory control server device). MSVC) transmits monitoring information MI. The monitoring control server device MSVB and the monitoring control server device MSVC receive the monitoring information MI from the monitoring control server device MSVA, and store the monitoring information MI in a storage unit (not shown). Thereby, the centralized monitoring control system 1 synchronizes the monitoring information MI of the monitoring control server device MSV included in each server site S by the monitoring control function.
The monitoring control server apparatus MSV has a state monitoring function. The state monitoring function is a function of detecting a communication failure between the own device (monitoring control server device MSV) and another monitoring control server device MSV. In this example, the state monitoring function is a function for detecting whether or not a communication failure has occurred in the wide area network hN. Here, there are cases where the state monitoring function detects a communication failure and the detected operation mode of the monitoring control server apparatus MSV is a standby operation. In this case, the state monitoring function changes the operation mode of the monitoring control server apparatus MSV to the normal operation. That is, when a communication failure has occurred in the wide area network hN and the function of each monitoring control server apparatus MSV has not been lost, the operation modes of the monitoring control server apparatus MSV provided in the centralized monitoring control system 1 are all normal operations. It is. The loss of the function of the monitoring control server device MSV is a state where the monitoring control server device MSV cannot perform at least one of the monitoring and control of the equipment EQ to be monitored and controlled due to a server device failure or the like.
The state monitoring function is a function for detecting whether or not the function of the monitoring control server apparatus MSV for normal operation is lost. Here, the state monitoring function of the monitoring control server apparatus MSV for standby operation may detect that the function of the monitoring control server apparatus MSV for normal operation is lost. In this case, in response to detecting that the function of the monitoring control server apparatus MSV for normal operation has been lost, the operation mode of one monitoring control server apparatus MSV among the monitoring control server apparatuses MSV for standby operation is the normal use mode. Transition to operation.

In the monitoring control server apparatus MSV, an operation mode at the time of activation is set in advance. In the following description, the setting of the operation mode at the time of startup is referred to as initial setting. In this example, the monitoring control server apparatus MSVA, the monitoring control server apparatus MSVB, and the monitoring control server apparatus MSVC operate normally, and the monitoring control server apparatus MSVB and the monitoring control server apparatus MSVC operate in standby mode. The initial setting is preset. The monitoring control server apparatus MSVA, the monitoring control server apparatus MSVB, and the monitoring control server apparatus MSVC operate by selecting an operation mode based on the initial setting when the apparatus is started or restarted.
The monitoring control server apparatus MSV is assigned a priority in advance for each monitoring control server apparatus MSV. In this example, the monitoring control server apparatus MSVA has a higher priority than the monitoring control server apparatus MSVB. Further, the supervisory control server device MSVB has a higher priority than the supervisory control server device MSVC. The state monitoring function changes the operation mode of the monitoring control server apparatus MSV having a higher priority among the monitoring control server apparatuses MSV in which the function of the monitoring control server apparatus MSV has not been lost to the normal operation. Therefore, when the function of the monitoring control server apparatus MSVA is lost, the monitoring control server apparatus MSVB operates normally, and the monitoring control server apparatus MSVC operates in standby. When the functions of the monitoring control server apparatus MSVA and the monitoring control server apparatus MSVB are lost, the monitoring control server apparatus MSVC operates normally.

[Operations for synchronization between servers: Stop operation of the primary server]
Hereinafter, the synchronization of the monitoring information MI of the centralized monitoring control system 1 will be described with reference to the drawings.
FIG. 8 is a first flowchart showing an example of the operation of the monitoring control server apparatus MSV of the first embodiment.
The supervisory control server device MSV determines whether the device itself is a normal operation or a standby operation at all times or at predetermined time intervals (step S710). When the monitoring control server apparatus MSV determines that the own apparatus is in a normal operation (step S710; YES), the monitoring control server apparatus MSV transmits the monitoring information MI to the other monitoring control server apparatus MSV that is in standby operation. (Step S720). When the monitoring control server apparatus MSV determines that the own apparatus is in a standby operation (step S710; NO), whether or not the operation of the monitoring control server apparatus MSV having one higher priority than the own apparatus has changed from the normal operation to the stop operation. Is detected (step S730). When the monitoring control server apparatus MSV of the standby operation has not detected that the monitoring control server apparatus MSV having one higher priority than the own apparatus has changed from the normal operation to the stop (step S730; NO), the process proceeds to step S710. Proceed. When the monitoring control server apparatus MSV of the standby operation detects that the operation of the monitoring control server apparatus MSV having one higher priority than the own apparatus has changed from the normal operation to the stop (step S730; YES), the monitoring operation server apparatus MSV starts from the standby operation. The operation mode is changed to the normal operation (step S740).

[Synchronization between servers: Communication failure occurred]
Hereinafter, the synchronization of the monitoring information MI of the centralized monitoring control system 1 will be described with reference to the drawings.
FIG. 9 is a second flowchart illustrating an example of the operation of the monitoring control server apparatus MSV of the first embodiment.
The monitoring control server device MSV determines whether the own device is in a normal operation or a standby operation at all times or at predetermined time intervals (step S410). When the monitoring control server apparatus MSV determines that the own apparatus is in a normal operation (step S410; YES), the monitoring control server apparatus MSV transmits the monitoring information MI to the other monitoring control server apparatus MSV that is in standby operation. (Step S420). When the monitoring control server apparatus MSV determines that the own apparatus is in a standby operation (step S410; NO), the monitoring control server apparatus MSV detects whether or not a communication failure has occurred (step S430). If the monitoring control server apparatus MSV for standby operation does not detect that a communication failure has occurred in the network (in this example, the wide area network hN) (step S430; NO), the process proceeds to step S710. When the standby operation monitoring control server apparatus MSV detects that a communication failure has occurred in the wide area network hN (step S430; YES), the operation mode is changed from the standby operation to the normal operation (step S440). .

  Note that the regular operation monitoring control server apparatus MSV replaces the configuration in which the monitoring information MI is transmitted to all the standby operation monitoring control server apparatuses MSV, and at least a part of the monitoring operation monitoring control server apparatus MSV in the standby operation monitoring control server apparatus MSV. The configuration may be such that the monitoring information MI is transmitted to the server apparatus MSV. The monitoring control server apparatus MSV of the standby operation includes at least a part of the monitoring control server apparatus MSV, for example, the monitoring control server apparatus included in the control station C adjacent to the control station C including the normal operation monitoring control server apparatus MSV. MSV.

Note that the system board server device CSV may also be configured to perform a normal operation and a standby operation similarly to the monitoring control server device MSV. That is, in order to enable monitoring of the equipment EQ of the centralized monitoring control system 1 by any of the system board server devices CSV at the three server bases S, the equipment function EI of the equipment EQ to be monitored is maintained with the maintenance function, and In addition to synchronization (equivalent) by the maintenance interface function, it is preferable to synchronize (equivalent) information about the monitoring information MI. In this example, a case will be described in which the system board server device CSVA is normally operated during normal times, and the system board server device CSVB and the system board server device CSVC are in standby operation.
The system board display function of the system board server CSV (in this example, the system board server apparatus CSVA) that operates normally is the system board server CSV (in this example, the system board server apparatus CSVB, and the system board server) that operates in standby mode. The monitoring information MI is transmitted to the device CSVC). The system board server device CSVB and the system board server device CSVC receive the monitoring information MI from the system board server device CSVA and store the monitoring information MI in a storage unit (not shown). Thereby, the centralized monitoring control system 1 synchronizes the monitoring information MI of the system board server device CSV included in each server base S by the system board display function.
Further, the system board server device CSV has a state monitoring function. The state monitoring function is a function for detecting a communication failure between the own device (system board server device CSV) and another system board server device CSV. In this example, the state monitoring function is a function for detecting whether or not a communication failure has occurred in the wide area network hN. Here, there are cases where the state monitoring function detects a communication failure and the detected operation mode of the system board server device CSV is a standby operation. In this case, the state monitoring function changes the operation mode of the system board server device CSV to the normal operation. That is, when a communication failure has occurred in the wide area network hN and the function of each system board server device CSV has not been lost, the operation mode of the system board server apparatus CSV provided in the centralized monitoring control system 1 is a normal operation. It is. The loss of the function of the system board server device CSV means that the system board server device CSV cannot monitor the equipment EQ to be monitored due to a server apparatus failure or the like.
The state monitoring function is a function for detecting whether or not the function of the system board server device CSV for normal operation is lost. Here, the state monitoring function of the standby operation system board server device CSV may detect that the function of the normal operation system board server device CSV is lost. In this case, in response to detecting that the function of the system board server device CSV for normal operation has been lost, the operation mode of one system board server device CSV among the system board server devices CSV for standby operation is in normal use. Transition to operation.

Moreover, also about the system | strain board server apparatus CSV with which the centralized monitoring control system 1 is provided, initial setting may be preset previously similarly to the monitoring control server apparatus MSV. In this example, for each of the system board server device CSVA, the system board server apparatus CSVB, and the system board server apparatus CSVC, the system board server apparatus CSVA is regularly operated, and the system board server apparatus CSVB and the system board server apparatus CSVC are in standby operation. The initial setting is preset. The system board server device CSVA, the system board server device CSVB, and the system board server device CSVC operate by selecting an operation mode based on the initial setting when the device itself is activated or restarted.
Moreover, the system board server device CSV may be assigned a priority in advance for each system board server device CSV. In this example, the system board server device CSVA has a higher priority than the system board server device CSVB. The system board server device CSVB has a higher priority than the system board server device CSVC. The state monitoring function changes the operation mode of the system board server device CSV having a higher priority among the system board server apparatuses CSV in which the function of the system board server apparatus CSV has not been lost to the normal operation. Therefore, when the function of the system board server apparatus CSVA is lost, the system board server apparatus CSVB operates normally, and the system board server apparatus CSVC operates in standby. Further, when the functions of the system board server device CSVA and the system board server device CSVB are lost, the system board server device CSVC operates normally.

According to the centralized monitoring control system 1 of the present embodiment, the monitoring control function synchronizes (equivalents) the monitoring information MI of the monitoring control server device MSV included in the centralized monitoring control system 1.
As a result, the centralized monitoring control system 1 of the present embodiment transitions between the normal operation and the standby operation even if any of the monitoring control server devices MSV included in each server base S has a problem. Thus, the equipment EQ is monitored and controlled.
Therefore, according to the centralized monitoring control system 1 of the present embodiment, even when a network failure or a server failure occurs, the failure can be quickly recovered by switching the normal operation and standby operation of the monitoring control server device MSV. can do.
Further, according to the centralized monitoring control system 1 of the present embodiment, the normal operation and the standby operation of the monitoring control server device MSV are automatically switched, thereby reducing the trouble of the system administrator switching the operation by manual setting. Can do. That is, according to the centralized supervisory control system 1 of the present embodiment, the supervisory control systems installed in each jurisdiction area are consolidated into a smaller number of supervisory control server devices MSV than the number of jurisdictions, and the installation location of the supervisory control system The equipment EQ can be monitored and controlled without depending on (region of jurisdiction). Thereby, the centralized monitoring control system 1 with high availability can be realized.

In addition, the centralized monitoring control system 1 of the present embodiment switches between the regular facility information storage unit IU and the emergency facility information storage unit IF when the monitoring control server device MSV is on standby. For example, when switching is performed when the monitoring control server apparatus MSV is in normal use, the facility information EI that is the operation reference is changed during normal use. In this case, transmission / reception of information between the monitoring control server apparatus MSV and the facility EQ is normal. May not be done.
The centralized supervisory control system 1 of the present embodiment switches between the regular equipment information storage unit IU and the emergency equipment information storage unit IF when the supervisory control server device MSV is on standby. Therefore, the equipment information EI is not changed when information is transmitted and received between the monitoring control server apparatus MSV and the equipment EQ for normal operation. Thereby, the centralized monitoring control system 1 of this embodiment can suppress that information transmission / reception between the server apparatus and the equipment EQ is not normally performed when the transmission / reception destination becomes indefinite.

  In addition, the monitoring control server device MSV of the centralized monitoring control system 1 of the present embodiment includes a database (equipment information storage unit EM in this example) that stores power facility information (equipment information EI in this example). Therefore, according to the centralized monitoring control system 1 of the present embodiment, it is possible to reduce the cost associated with arranging a database for storing power equipment information for each monitoring control system.
