Substation signal intelligent monitoring method and system based on agent

Abstract

The application discloses a substation signal intelligent monitoring method and system based on an agent, relates to the technical field of substation signal monitoring, and comprises the following steps: constructing a physical abnormal conduction relationship corresponding to a physical topology link and a signal abnormal conduction relationship corresponding to a signal topology link according to the physical operation mechanism and the signal transmission mechanism of power equipment; classifying power equipment in the monitoring range of the same environment monitoring equipment into the same monitoring set, and acquiring spatial state deviation influence according to historical signal data and historical spatial states of the same type of power equipment in different monitoring sets; outputting the comprehensive abnormal probability of each power equipment according to real-time signal data, spatial state deviation influence, the physical abnormal conduction relationship and the signal abnormal conduction relationship; and outputting an abnormal positioning result according to the comprehensive abnormal probability by using the reasoning mechanism of the agent. The application takes into account the abnormal sensing sensitivity and the alarm output reliability.
