To reduce the active power and DC voltage fluctuation and accelerate tracking speed during system start, this paper proposes a new strategy setting reactive power reference based on the error between the instantaneous active power and its reference.

 
  • 为了抑制电压型PWM整流器直接功率控制中的有功功率、直流电压波动,加快系统的跟踪速度,提出了根据有功功率瞬时值与有功功率给定的差值设定无功功率给定值的新策略。 当有功功率瞬时值与有功功率给定的差值小于给定临界值时,无功功率给定值为零;
