Multi-theme intelligent comprehensive alarm analysis method for power grid equipment monitoring

Abstract

The invention relates to a power grid equipment monitoring oriented multi-subject intelligent integrated alarm analysis method which comprises the steps that (1) alarm information is subscribed, and classified by taking an interval as a unit; and (2) when a certain interval is accessed, the following subject data is provided for selection: 1) corresponding wiring diagram data is obtained according to the accessed interval; 2) holographic telemeasuring data of a key parameter of the interval within a period before and after the generated time of the alarm information is acquired according to the interval to which the alarm information belongs; 3) the latest alarm information of the interval is obtained according to the interval to which the alarm information belongs; 4) listing information of the interval is obtained according to the interval to which the alarm information belongs; and 5) equipment electric parameter static information and equipment overhaul records of the interval are obtained according to the interval to which the alarm information belongs. The multi-subject analysis and statistical method provides a quicker and richer means for dispatching automation personnel to check and analyze the alarm information generated during power grid running and for overall monitoring on equipment.

Description

technical field [0001] The invention relates to a multi-theme intelligent comprehensive alarm analysis method adopted in power grid equipment monitoring, and belongs to the technical field of power system informatization and automation. Background technique [0002] In the actual dispatching of the power system, the state of the key grid equipment is related to the stable operation of the grid, and it plays a very important role in the monitoring of the grid equipment. At present, the smart grid dispatching technical support system has been widely used in the power system, and the operation status and operation data collection of the key equipment of the power grid is relatively comprehensive, especially after the time series database is integrated into the smart grid dispatching technical support system. It can record the operation holographic data of the power grid, etc. How to effectively use these data to play a greater role in the stable operation of the power grid has...

AI Technical Summary

Problems solved by technology

It can be seen that the operation required by the dispatcher in this process is very cumbersome, and it is necessary to understand the specific location of the data in the system or various graphical tools to view

And the alarm information is a simple journal based on time, which cannot directly count the alarm information of a certain interval

These important data cannot be provided to dispatchers through automated means to analyze and locate the cause of the accident, and the data is relatively discrete and lacks effective correlation means
