Research on the Influence Factors of Corona Discharge at the End of the Stator Winding of MW Level Flywheel Energy Storage
The MW level flywheel energy storage voltage reaches kilovolt level,with a frequency of over 500Hz,and operates under low air pressure,posing a new challenge to the anti corona ability of the stator winding of the electric machine.This article uses air pressure and frequency as influencing factors,and conducts simulation calculations and experimental verification to study their impact on the discharge of the stator winding.The research results indicate that in terms of single factor influencing factors,the influence of air pressure on winding corona discharge is significantly greater than the influence of frequency,and the combined effect of the two will cause another sudden decrease in corona inception voltage.
