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. For the single-machine infinite system, the system equations of the static synchronous compensator are established by using the salient-pole generator (x’d ≠ xq) model, and the geometric feedback linearization method is used to realize the coordinated control of generator excitation and STATCOM. Method to make up for the lack of coordination research of salient-pole generator excitation and STATCOM, and further extend the application of geometric linearization theory and controller and improve the practicality of STATCOM and excitation coordination control.The simulation results verify that The proposed model and the method of coordination control are reasonable and effective.
