Rules-based intelligent system for grid fault diagnosis

Abstract

The invention relates to a rules-based intelligent system for grid fault diagnosis, comprising a real-time data acquisition module, a data receiver, a preprocessing module, a working database, a knowledge base, an inference engine and a command generator. The real-time data acquisition module acquires real-time data information of a grid and sends it to the data receiver; the data receiver performs reasonableness testing and encoding; the preprocessing module performs formatting and information fusing and sorting and stores the information in the working database; the working database sends a command to the inference engine; the inference engine sends an inference verification request to the knowledge base; the knowledge base acquires data from the working database and performs data matching on the basis of a grid CIM (common information model) according to knowledge rules in the knowledge base built; the inference engine performs inference analysis according to the data in the working database, system state and knowledge in the knowledge base. The system has the advantages that a self-learning function is achieved, checking and error correcting is facilitated and grid fault diagnosis is more efficient.

Description

technical field [0001] The invention relates to the technical field of grid operation safety, in particular to a rule-based grid fault diagnosis intelligent system. Background technique [0002] The development of the power grid and the progress of the society have put forward higher requirements for the operation safety of the power grid, and it is particularly important to strengthen the diagnosis and treatment of power grid faults. With the development of computer technology, communication technology, network technology, etc., it has important research value and practical significance to use more advanced intelligent technology to improve the performance of power grid fault diagnosis system. Intelligent fault diagnosis technology is also called intelligent fault diagnosis technology. Intelligent fault diagnosis is a new method that incorporates artificial intelligence technology. It has preliminary automatic analysis and learning capabilities for fault information. Common...
