The open loop time constant of the main generator influence the overshooting evidently. The important factor is the rising speed of the output DC voltage.

主发电机的开环时间常数会对建压过冲产生影响，而输出直流电压的上升速度也是一个重要因素。

An example is the speed control system of a turbine-generator set in a power station, whose main purpose is to maintain the generator speed as nearly constant as possible.

电厂涡轮发电机组就是一个例子，它主要的目的是维持发电机的转速尽可能的接近于恒值。

In recent years, the variable speed constant frequency wind generator system is the most widely question for discussion at home and abroad, especially for doubly-fed induction.

变速恒频风力发电系统是近年来国内外研究最广泛的课题，其中最具代表性的是绕线式转子双馈异步发电系统。
