Abstract

The invention discloses a state monitoring and intelligent diagnosis and analysis system and method for power transmission and transformation equipment. The system comprises a data access module for accessing state monitoring data of the power transmission and transformation equipment, and a comprehensive diagnostic analysis module, which comprises a transformer diagnostic analysis unit for analyzing the faults of a transformer winding lead, oil-paper insulation, an iron core, a firmware structure and a bushing according to the state monitoring data; an arrester leakage current analysis unit for analyzing the leakage current of an arrester according to the state monitoring data; a power cable diagnostic analysis unit for analyzing the fault of a power cable according to the state monitoring data; a gas diagnostic analysis unit for analyzing the gas in the transformer according to the state monitoring data and diagnosing the fault of the transformer according to a gas analysis result. The system and method can enhance the flexibility of the power transmission and distribution equipment configuration, improve the detection level of the power transmission and transformation equipment, and reduce overhaul and maintenance cost.

Description

technical field [0001] The invention relates to the technical field of power monitoring, in particular to an intelligent diagnosis and analysis system and method for status monitoring of power transmission and transformation equipment. Background technique [0002] With the promotion and application of status monitoring systems for power transmission and transformation equipment in the power grid, most of the existing status monitoring technologies are developed for a specific device or application platform, and cannot be organically combined with other important status quantities, making it difficult to realize timely resource monitoring. Sharing, the lack of a unified platform, cannot effectively play its role in auxiliary diagnosis. Therefore, it is particularly important to establish an intelligent power transmission and transformation equipment condition monitoring system that is easy, open, high in access efficiency, and standardized in data models to promote the devel...
