It is found that the total system imbalance power during fault is almost a constant and may be calculated from the imbalance power of arbitrary generator.
在研究中发现了故障期间全系统的加速功率几乎不变，且与任意发电机的加速功率之间存在简单关系。

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。
