Monitoring alarm signal clustering method taking power grid event as center

Abstract

The invention discloses a monitoring alarm signal clustering method taking a power grid event as a center, and the method comprises the following steps: 1, extracting feature information based on a standard signal in a monitoring information specification, and forming a standard signal feature point mapping model; 2, based on expert experience of a power system, constructing a power grid event model according to logic of manually analyzing power grid events; 3, based on historical power grid event analysis report, historical monitoring data and measurement data, performing event model deduction and improvement; 4, performing structural analysis on the monitoring alarm information, and matching a standard signal; 5, performing event analysis in combination with the power grid topology and the operation mode, and performing multi-dimensional cross confirmation in combination with the telemetry information; and 6, clustering the monitoring alarm signals related to the events based on an event analysis result. According to the invention, the processing confirmation time of monitoring alarm signals is effectively reduced, the working pressure of operators is reduced, and the monitoringmanagement level of a power grid is improved.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to intelligent monitoring and analysis technology of power grid events. Background technique [0002] With the rapid development of my country's power grid, the promotion of integrated regulation and control mode, and the gradual integration of large-scale operation and major maintenance systems, the dispatching organization has increased the centralized monitoring function of equipment, and the role of the production command center of the power grid dispatching center has become more prominent. The quality also puts forward higher requirements. The number of substations under centralized monitoring by the control center has increased sharply. The primary and secondary equipment monitoring signals are centrally monitored at the main dispatching station. The number of monitoring and alarm signals generated in a single day has reached 10,000, and there are differences...

AI Technical Summary

Problems solved by technology

The number of substations under centralized monitoring by the control center has increased sharply. The primary and secondary equipment monitoring signals are centrally monitored at the main dispatching station. The number of monitoring and alarm signals generated in a single day has reached 10,000, and there are differences in the signals due to the professional level of maintenance personnel and the differences in localized experience. Irregular phenomenon

In the face of a large number of signals, relying entirely on manual experience to judge, there is a problem that the alarm information cannot be effectively monitored, and the key information of the perception of the power grid event may be missed due to omission
