摘要
励磁系统和FACTS装置的不协调设计会导致电网的鲁棒性变差。基于多输入多输出系统的励磁控制装置和STATCOM(同步无功补偿器)数学模型,利用零动态设计原理对系统PSS参数与STATCOM进行协调设计,分别在PSS与STATCOM协调和不协调两种情况下,应用DIg SILENT/Power Factory软件对系统进行仿真,根据仿真结果得出,零动态设计原理可以显著提升含风电多机系统的动态稳定性且具有优良的品质。
The uncoordinated design of FACTS devices with excitation systems may deteriorate robustness of the power system. Based on mathematic model of STATCOM and excitation system controllers of a Multiple Input Multiple Out- put （MIMO） system, the design method of a nonlinear control technique, named zero dynamics is given in the paper to design the controllers of PSS and STATCOM. The power system is simulated respectively at the instance of coordinated and uncoordinated to design the controllers of PSS and STATCOM by DigSILENT/PowerFactory. Simulations results clearly verify that the zero dynamics method both improves dynamic stability and performance of the power system with wind generation.
