摘要
为提高含静止无功补偿器(static var compensator,SVC)电力系统的功角稳定性和电压稳定性,针对电力系统的非线性和建模不准确性,提出一种基于协同控制理论的SVC新型非线性控制器(SVC nonlinear controller based on synergetic control,SNC)。首先设计考虑电压稳定和功角稳定的宏变量和流形,接着推导出基于协同控制的静止无功补偿器的控制解析表达式,并探讨各控制参数的选取原则。最后将所设计的SNC应用于四机两区域系统和IEEE9节点系统,采用PSCAD/EMTDC仿真验证。与传统SVC附加控制器(SVC conventional supplementary controller,CSC)相比,所提SNC在给系统提供阻尼的同时,能够更为快速地使电压回归稳定。
In order to improve the power angle stability and voltage stability of power system that contains static var compensator（SVC）, this paper puts forward a SVC nonlinear controller（SNC） based on synergetic control theory.The macro variables and manifold are designed considering the voltage stability and power angle stability, then the analytical expression of the control of static var compensator based on synergetic control is derived, and the determination principle of each control parameter is discussed.The designed SNC is applied to a two-area system and IEEE9 node system, which is verified by PSCAD/EMTDC simulation.Compared with the SVC conventional supplementary controller（CSC）, the proposed SNC in this paper is more effective to stabilize the voltage of the system while providing damping to the system.
