摘　　要：针对现有静止无功发生器电流环PI控制器超调量大、响应速度慢的问题,提出一种基于前馈补偿和小时间常数微分负反馈的电流环PI控制策略,并与现有控制策略进行比较分析。实验结果证明,所提出的电流环控制策略能够实现降低超调量和加快响应速度的目的。For the current static var generator current loop PI controllers have large amount of overshoot and slow response,one kind of current loop PI control strategy based on the feedforward compensation and small time constant differential negative feedback has been proposed,and is compared with the existing control strategies.Experimental results show that the current loop control strategy presented can realize the object of reducing overshoot and response time.
