Study on Power Transmission and Transformation Equipment Intelligent Operation and Maintenance System and Its Application

Abstract

Abstract:

For operation and maintenance management of power transmission and transformation equipment, this paper used of power production management system(PMS), power geographic information system(GIS), energy management systems(EMS) and other business systems to establish a power transmission and transformation equipment intelligent operation and maintenance system. By breaking the information island in various business systems, this paper proposed the health of the state of a device benchmark analysis method to evaluate equipment, and from both equipment importance and equipment health to grading equipment. System Used case-based reasoning and rule-based reasoning for fault prediction, to determine the equipment failure modes. Ultimately, maintenance decision module combined the results of the state evaluation module, risk assessment module, monitoring & warning module and fault forecast module to give the differential operational suggestions. This system by analysing the case of the diagnostic process of a transformer, proved that the system is able to provide the diagnosis and policy recommendations of transmission and transformation equipment with scientific and accurate.

Key words: benchmark analysis, control classification, reasoning diagnosis, differential operational
