Automatic response system for power grid alarm and automatic response method for power grid alarm

Abstract

The invention discloses a power grid alarming automatic response system which structurally comprises a data summarization port, a concluded module, a contradiction analysis module, a logic analysis module, a power grid response rule module, a memory module and a man-machine interface. The power grid alarming automatic response is carried out by means of the power grid alarming automatic response system according to the steps that (A) the data summarization port collects and summarizes alarming data of a power grid in real time, (B) the data collected in the step A are concluded according to class attributes to form data classes, (C) the contradiction analysis module removes noise data, (D) the logic analysis module analyzes the data classes obtained in the step C one by one according to a database stored in the memory module, (E) the power grid response rule module carries out relevance processing to obtain a specific response rule dealing with the alarm, and (F) the response rule obtained in the step E is conveyed and displayed to a man-machine interface. The system can greatly reduce influences of alarm noise on work of a dispatcher and can automatically deal with common alarms.

Description

technical field [0001] The invention relates to the technical field of power grid monitoring, in particular to a power grid alarm automatic response system and a use method thereof. Background technique [0002] With the rapid development of my country's electric power industry, the installed capacity of the power grid is increasing rapidly, and the scale of the power grid is also expanding. The structure is also complicated, and the operation mode is various. The alarm information presented to the dispatcher is also increasing. According to the survey of the power grid dispatching automation system in a certain area, under normal circumstances, the alarm information uploaded within one minute ranges from dozens to hundreds, and these alarm information includes telemetry over-limit events, equipment abnormal events, and switch events. , Knife switch matters, protection matters, transformer matters and many other contents. If the power grid fails, more items will be uploaded...

AI Technical Summary

Problems solved by technology

Whether it is general remote signals such as switch and knife switch displacement, or important information such as device abnormality and protection action, etc., all are displayed in the alarm window. Even if the operator reads and analyzes item by item, it is not easy to immediately determine what happened.

Even in some monitoring sites that use intelligent alarm systems, there are still about 14% of alarm information noise that cannot be filtered out

[0005] 2. Since more than 80% of the important alarms in the power grid are common alarms, but for the common important alarms, manual intervention by the dispatcher is still required, which greatly increases the repetitive workload of the dispatcher and cannot make the dispatcher concentrate on dealing with new occurrences abnormal alarm
