燃气发电机组一次调频动作的暂态分析及优化策略

Analysis and optimization strategy of primary frequency regulation

文章先阐述了电力系统频率调整对于国民经济的重要程度,然后从发电机转子所受力矩入手进行分析,分别得出了原动机机械功率的频率特性模型和负荷电磁功率的频率特性模型。针对上面两个模型对一次调频动作的暂态过程进行了分析。随后文章解读了华北地区一次调频的考核细则,最终给出了3种优化一次调频调节性能的方法。

In this paper,the importance of power system frequency adjustment to national economy is discussed,and then the frequency characteristic model of prime mover mechanical power and the frequency characteristic model of load electromagnetic power are obtained by analyzing the torque of generator rotor.The transient process of the first frequency modulation action is analyzed for the above two models.Then the detailed rules of primary frequency modulation in North China are interpreted,and three methods to optimize the performance of primary frequency modulation are given.
