Research On Equipment Condition Monitoring System In Intelligent Substation

With the development of the intelligent substation construction process promoted by China State Grid Corp, condition monitoring plays an increasingly important role in intelligent substation. It can observe the working condition of power equipment at the measurement time, facilitating the detection of hidden dangers and the change trend in time.On the other hand, through the integrated diagnosis of equipment operation, condition monitoring promotes the transition from regular test to the state test of power equipment and effectively extends the service life of the equipment.Based on the study of the current condition-monitoring technology and main equipment manufacturers, this paper describes the monitoring principle and the configuration scheme of the main equipments in the intelligent substation, discusses the standardization of information flow of the Secondary Electric Power Equipment self-checking and self-diagnostic status monitoring.Finally, taking a 220kV intelligent substation as an example, this paper introduces the configuration scheme of the condition-monitoring system of intelligent substation at present.
