An intelligent analysis platform and analysis method for lightning strike faults of transmission lines

Abstract

The invention belongs to the technical field of fault analysis of transmission lines, and in particular relates to an intelligent analysis platform and analysis method for lightning strike faults of transmission lines, including an EMS system, a relay protection information system, a power grid lightning location center and end users, and a transmission line fault information analysis system , the transmission line fault information analysis system collects and obtains the data information of the EMS system, the relay protection information system, the power grid lightning location center and the end user in real time, and the present invention uses the pre-acquisition unit and the database service unit of the transmission line fault information analysis system , an intelligent analysis unit and an application information display unit for data access, intelligent diagnosis, and display of lightning fault information for analysis. The present invention improves the current application defect of lightning monitoring on transmission lines and provides lightning fault analysis result information for post-disaster processing of lightning tripping accidents. Supporting decision making.

Description

technical field [0001] The invention belongs to the technical field of fault analysis of transmission lines, and in particular relates to an intelligent analysis platform and analysis method for lightning strike faults of transmission lines. Background technique [0002] For a long time, according to the existing lightning monitoring system, the judgment of lightning strike faults and the accurate search of lightning strike fault points are inquiries after the accident. Since the inquiry requires manual intervention and judgment, the lightning monitoring system fails to automatically diagnose and propose lightning strike accidents on transmission lines in time. Auxiliary decision-making opinions to guide the safe operation of the power grid. In order to realize the intelligent and real-time automatic diagnosis of lightning tripping of transmission lines, the line tripping information and fault distance measurement information in the dispatching EMS system are connected to the...

Problems solved by technology

[0009] The existing line location information is mainly collected by the line inspectors in the daily line inspection work using GPS. There are objective reasons such as GPS accuracy errors and manual errors. In addition, due to the commissioning of the new line, the line location information cannot be obtained in time, resulting in At present, no system has comprehensive and accurate line location information. After years of accumulation, the lightning location system has entered part of the line location information, but the fault distance measurement information and fault tower number information have not yet been accessed.
