Online monitoring method and system with function of automatically setting switch cabinet monitoring parameters

Abstract

The invention provides an online monitoring method and system with a function of automatically setting switch cabinet monitoring parameters. According to the following technical scheme, the online monitoring system comprises an online monitoring server and a plurality of monitoring devices mounted on switch cabinets; the online motoring server is used for grouping the switch cabinets provided withthe monitoring devices and selecting one of the switch cabinet as a group monitoring point; various monitoring parameter models are arranged according to various model selecting factors, and the arranged monitoring parameter models are issued to the group monitoring point; and the group monitoring point distributes the monitoring parameter models for all the switch cabinets in groups according tothe model selecting factors of all the switch cabinets in the groups. The monitoring devices obtain required monitoring parameter threshold values according to the actual situations, and alarming isconducted according to the actual situations, so that alarming accuracy is improved, and the load pressure of the online monitoring server is effectively reduced by grouping the switch cabinets and arranging the group monitoring point.

Description

Background technique [0001] High-voltage switchgear is a very important electrical equipment in the power system. The abnormal operation status of the switchgear will cause the failure of the power system. Therefore, monitoring the operation status of the switchgear and finding hidden troubles in time will ensure the normal operation of the switchgear and reduce the number of maintenance. It is of great significance to improve the operation reliability of the power system. At present, the on-line monitoring system of the switchgear has been widely used. In these on-line monitoring systems, a unified monitoring index is often used to monitor the switchgear. However, due to different models, Due to various factors such as different manufacturers and different hours of use, for different switch cabinets, if the same monitoring indicators are used for them, the monitoring effect will often be poor, and even the abnormal status will be misjudged. Currently, the online monitoring sys...

Currently, the online monitoring system often uses the same Monitoring different switchgears based on local monitoring indicators, and setting alarm parameter thresholds for each switchgear individually when installing monitoring equipment is often time-consuming and laborious, and it is easy to make mistakes due to different indicators during the monitoring process, and a large number of switchgears use the same Monitoring server management is prone to the problem of downtime caused by excessive server load. Therefore, it is urgent to develop an automatic online monitoring system that can accurately monitor different switch cabinets and save time and effort to set monitoring indicators.
