A method for secondary intelligent classification of substation equipment monitoring information alarms

Abstract

The invention belongs to the technical field of substation monitoring, and discloses a method for secondary intelligent grading of substation equipment monitoring information alarms. When accidents, abnormalities, limit violations, displacements, and notifications of five-level monitoring information action or return are met, alarm suppression signs are provided. If the information has no warning suppression mark, maintenance and listing mark, and defect mark, it will be judged after all three conditions are met: the monitoring information is originally a notice level , if the number of actions within a period of time reaches the abnormal standard, the information will be upgraded from the secondary classification of the notification level to the abnormal level; and so on. Compared with the fixed grading of monitoring information, the present invention can not only prevent invalid information such as maintenance or defects from interfering with the monitoring of normal operating equipment by the monitor, but also prevent the occurrence of events that the monitor misses the monitoring of important information alarms, achieving It achieves the effect of highlighting the focus and clear layers.

Description

technical field [0001] The invention belongs to the technical field of substation monitoring, in particular to a method for secondary intelligent classification of substation equipment monitoring information alarms. Background technique [0002] With the completion of the "big operation" system of the State Grid Corporation of China, the substation has realized the operation and management mode of unattended and centralized monitoring. The monitoring information of the substation is all collected in the dispatching control center. The information analysis and processing workload of the monitors is heavy. The monitors cannot detect or miss important information alarms in time, and due to the interference of invalid information such as maintenance, the monitors misjudge faults or abnormalities. Events occur from time to time, which have a great impact on the safe and stable operation of the power grid. [0003] The monitoring information alarm is the alarm clause that appears...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to equipment maintenance, equipment defects, etc., the monitoring information alarms are frequently issued, which affects the normal monitoring of the monitors

During equipment maintenance, a large amount of maintenance and debugging information (such as XX protection exit, XX switch opening, etc.) will be generated. equipment monitoring

In addition, due to defects such as moisture or vibration of equipment information contacts, a certain monitoring information will also cause frequent alarms, which will affect the normal monitoring of the monitor.

[0005] (2) After the alarm classification of monitoring information is fixed, the prompting effect on important abnormalities and abnormal switch displacements is not obvious, and it is easy for important faults or abnormalities to be detected or missed in time.

[0007] At present, monitoring information is only graded according to the degree of impact of its description on the safe operation of the power grid or equipment, and the classification of each monitoring information is fixed. Judgment and disposal, other relevant records or data such as OMS or AVC system, and the degree of influence on the centralized monitoring of substations are used for comprehensive judgment and automatic adjustment

It is still necessary for monitors to make judgments based on experience and knowledge, and to search for relevant data and records, which prolongs the time to discover and deal with faults or abnormal events, and even directly leads to the failure of faults and important abnormal monitoring, bringing risks to the safe operation of power grids or equipment and hidden dangers
