摘要
基于发电机组一次调频的工作机理,探讨了发电机组一次调频性能的评价方法,并结合实际电网中较大的频率扰动事件,以省内部分机组的实际出力响应为例,计算机组一次调频性能指标,由此评价与分析一次机组的调频性能。
Based on the theory of primary frequency modulation of generator unit,this article discusses the method to evaluation the performance of primary frequency modulation. As an example,the article studies the real frequency disturbance on power grid and analyses the characters of primary frequency modulation based on output power curves of the units. And using the method discussed,the article evaluates the primary frequency modulation of some units in the power grid.
