Abstract

PURPOSE:To improve the efficiency of a diagnosis of a fault of an electric power system by making a history trace display of a power system picture before the fault occurrence. CONSTITUTION:Various state signals of the electric power system are inputted from a signal input means 1 to generate a system current state signal file 2. The file 2 is stored as a signal history file in a signal history storage means 4 by a signal history storage processing means 3 at every constant period and every time an event signal is inputted at a request for the start or stop of the storage from an operator. Then a system picture generating means 5 edits the file 2 to generate a system picture, which is displayed on a system picture display means 6. Further, the signal history file is read out and edited at an operator's request to generate a system picture, which is traced and displayed on the means 6 in order. Consequently, the fault occurrence transition of the system picture is easily grasped and the efficiency of the fault diagnosis is improved.

On the other hand, the device status file 21. created by the signal input means 1. The measured value current value file 22 is stored in the signal history storage means 4 at regular intervals and every event signal input by the signal history storage means 3 as shown in FIG. 3 in response to a request from the operator to start/stop storage. is saved as a signal history file. Here, the signal history storage means 4 is a circular file having n records, and the oldest data is updated to the latest data. The number n of records in this circulating file is arbitrary, but in order to perform sufficient analysis, it is set so that at least a history of about 30 minutes before the occurrence of a failure can be recorded. The signal history file stored in the signal history storage means 4 in this way is read in the system shown in FIG. 4 in response to a request from the operator, and a system screen is created by collecting the files. The power system screen is sequentially traced and displayed on the system screen display means 6 as the power system screen before the occurrence of the failure. Here, the display methods are BACKWARD TRACE41, which sequentially traces back to the previous time, such as 1 second and 2 seconds before the time of failure, and FORWA, which sequentially traces from the oldest system screen to the newest one.
There is RD TRACE42. That is, for example, if you want to understand the transition from 10 seconds before to the time of failure, first check BACKWARD TRACE41.
G: Go back 10 seconds, then FORWARD
TRACE42 sequentially displays traces. As described above, the trend of failure occurrence on the power system screen can be easily grasped.
