Monitoring Inspection Method for Synchronous Generator Rotor Insulation
With the development of China's power industry,the power system is becoming larger and more complex.Manual detection of the insulation resistance of generator rotor windings is time-consuming and labor-intensive,and it is increasingly unable to meet the needs of the power system.Therefore,this paper proposes a rotor insulation monitoring method for synchronous generators,which can automatically calculate the grounding resistance of generator rotor windings and be used to monitor the grounding resistance of synchronous generator rotor windings non-online.This paper elaborates the basic principle of synchronous generator,analyzes the occurrence of rotor grounding and its harmfulness,gives corresponding measures,and further proposes a monitoring method for rotor in operation.The method in this paper saves a lot of labor intensity of manual measurement and calculation,which is of great significance to ensure the safe and reliable operation of generators.
