Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a power system monitoring and control device.

[0002]

2. Description of the Related Art Each terminal station of a power system is connected to a master station of a control center by a transmission line, and remote monitoring control is performed. At present, it is very common that monitoring and control are performed by computer technology, and the control station master station has an equipment arrangement centered on electronic computers. As is well known, the control station master station is provided with peripheral devices including a system monitoring panel, a system monitoring panel, and a console, and these rooms are maintained in a favorable environmental condition suitable for each device.

[0003] Therefore, the abnormality of these peripheral devices has a serious effect on the monitoring and control of the power system, so that it is necessary to monitor the power system regularly to ensure the normal operation of the power system. In this case, if the diagnosis is performed periodically, the failure of the peripheral device is detected at the time of outputting the diagnosis periodically. With these periodic diagnostic outputs, in the event of a failure due to a temporary phenomenon that returns immediately after the failure occurs,
It is performed in a long cycle so that the operator is not notified.

[0004]

As described above, failures due to temporary phenomena are rarely detected even if they actually occur. It is difficult to find the cause because there is almost no reproducibility. Therefore, in these cases, for example, it is often the case that the related device is replaced or the state is viewed as it is. When such a temporary failure occurs, the user often enters the labyrinth.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and not only can an operator identify a device which is apt to be broken down, but also clarifies the causal relationship between the installation environment of the system and the occurrence of the breakdown. It is an object of the present invention to provide a power system monitoring and control device capable of performing such operations.

A plurality of system state detection devices, and a monitoring cycle setting device that changes a diagnosis cycle of the fixed cycle diagnosis device according to the environment of the installation location of each system. Diagnosis time was shortened.

According to a second aspect of the present invention, there is provided a power system monitoring and controlling apparatus according to the first aspect of the present invention, wherein the power system monitoring and control apparatus is provided in a case of entering a computer room or the like or of a housing of a system component device installed in the computer room or the like. When the door is opened or the door of the console is opened or closed, the period of time for the periodic diagnosis of transmission is shortened, and a peripheral device diagnosed as a failure is detected and notified to the operator.

According to a third aspect of the present invention, there is provided a power system monitoring and controlling apparatus according to the first or second aspect.
Diagnosis results are provided to operators by summarizing them by environment of peripheral devices and systems.
