This letter proposes an extended SVC model with thyristor firing angle law to improve transient performances of frequency and voltage of multi-machine power systems. A firing angle control synthesis framework for imposing any desired SVC susceptance value without linearization around a fixed operation point is proposed. In light of this method, the designed firing angle controller only requires local bus measures and parameters. The performance of the extended firing angle-controlled SVC model is evaluated on a 150-bus 27-machine power system and compared with conventional SVC model.

用于频率调节的扩展SVC建模

这封信提出了一个具有晶闸管触发角定律的扩展SVC模型，以改善多机电源系统的频率和电压的瞬态性能。提出了一种用于在固定工作点周围不线性化地施加任何期望的SVC磁化率值的点火角控制综合框架。根据这种方法，设计的点火角控制器仅需要本地总线措施和参数。扩展点火角度控制的SVC模型的性能在150总线的27机动力系统上进行了评估，并与常规SVC模型进行了比较。
