Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] The inventive method comprises the following steps:

[0026] 1. Build an internal expert knowledge base to describe the internal relationship of primary / secondary equipment attributes, switch action signals, protection action signals, and automatic device self-inspection signals in the power grid, and automatically monitor and analyze the power grid operation. The internal expert knowledge base is designed with C++ programming language, which includes the following parts: real-time remote signaling of power grid and static connection relationship, operation mode and topology relation knowledge base, alarm information classification and preprocessing knowledge base for monitoring and receiving SCADA alarm signals, Primary / secondary equipment operation knowledge base and fault analysis knowledge base, through the use of expert system reasoning control strategy t...

Abstract

The invention relates to an intelligent processing method for warning information of a combined power grid. The method comprises the following steps: the combination of an internal expert knowledge base and an external rule table, a multilayer-definition and analysis method of inter-signal incidence relation, and a definition method for both the rule table and an auxiliary signal table of ensuring relevance analysis completeness. According to the invention, an expert system principle and a control strategy are adopted to design the internal expert knowledge base so as to perform real-time analysis of various abnormalities and failures of the power grid; the external rule table is used for providing an analysis rule for the relevance of the abnormalities or failures of the power grid and SCADA (Supervisory Control And Data Acquisition) warning, so as to realize the external definition of the rule; the combined reasoning of both the internal expert knowledge base and the external rule table can ensure the completeness and accuracy of the signal analysis to the utmost; and the physical space attribute of signal is defined into such five layers as local station, local interval, local equipment, upper-level equipment and lower-level equipment, and the property of abnormalities or failures of the power grid is described in a multilayer way. Moreover, the auxiliary signal table is added into the external rule definition to ensure the completeness of the relevance signal of a warning analysis system.

Description

technical field [0001] The invention relates to a method for intelligently processing combined grid alarm information, which is mainly used for intelligently analyzing a large number of alarm information in the electric power dispatching automation SCADA system, so as to discover abnormalities and faults in the grid in time, and quickly provide dispatchers with Provides reference suggestions for fault and exception handling. Background technique [0002] In the power dispatching automation SCADA system, a large number of alarm signals are generated all the time, most of which are only suggestive information, and are also mixed with power grid fault information and abnormal information. The alarm function of the power dispatching automation SCADA system can only directly transmit and display this part of the information, lacks the ability to comprehensively analyze the alarm information, cannot discover the correlation relationship from the massive discrete information, and c...
