摘　　要：针对单机无穷大系统,采用凸极式发电机(x′d≠xq)模型,建立了包含静态同步补偿器的系统方程,并利用几何反馈线性化方法,实现发电机励磁与STATCOM的协调控制.该方法弥补了凸极式发电机励磁与STATCOM协调控制技术研究的不足,并进一步推广了几何线性化理论和控制器的应用范围,提高了STATCOM与励磁协调控制的实用性.仿真结果验证了文中所提出的模型和协调控制方法的合理性和有效性.A coordinated control method of power system including STATCOM is proposed.As an example of a single-machine infinite bus system,salient-pole generator model（x′d≠xq） and geometric feedback linearization method is adopt to realize the coordinated control between generator excitation and STATCOM.This method overcomes the defect of coordinated control for the salient-pole generator and STATCOM,it expands the applied domain of geometric linearization theory and controller,and makes the STATCOM model and control method more feasible for practical engineering applications.Finally,transient simulation results show the rationality and availability of proposed model and coordinated control method.
