永磁辅助磁阻发电机建压过程及短路故障运行
Voltage building process and short-circuit fault operation of PM-assisted synchronous reluctances generators
摘要
Abstract
A permanent magnet assisted synchronous reluctance power generation system(PMSynRG)is proposed to solve the difficulties of demagnetization during traditional permanent magnet generator short circuit faults and the voltage waveform difference of switched reluctance generators.A mathematical model of the motor is established,its power generation operation mechanism is explaint,and the steady-state voltage equation under load and the dynamic current equation for winding AC-DC axis short circuit during three-phase short circuit are derived.The numerical simulation calculation is conducted on the self-excited voltage building process of the generator under load,and the self-excited voltage building curve is obtained to verify the voltage building capacity of the generator system.Numerical simulation calculations were conducted for three-phase short circuit faults,verifying the conclusion that the three-phase current is less than the rated current during the fault.At the same time,the correctness of the dynamic current equation during three-phase short circuit was also verified,proving that the generator system has strong self-protection ability.A prototype was made and a load pressure building experiment was completed.The experimental results are in good agreement with the numerical analysis results.关键词
