摘要
基于飞轮储能的柔性功率调节器(FPC)是一种以储能原理为基础的新型FACTS装置。FPC能够快速与电力系统进行动态功率交换,改变系统的电气阻尼,从而抑制电力系统的功率振荡,增强电力系统的稳定性。本文基于含一台FPC的单机无穷大系统模型,分析了FPC阻尼功率振荡的机理,提出了其功率控制器的控制策略。根据所建立的模型和控制策略,在EMTDC/PSCAD环境建立了该系统的仿真平台,进行了详细的全时域数字仿真研究。并通过研制一台10kW的FPC样机进行电力系统动态模拟实验研究。研究结果表明,FPC改善了系统的阻尼特性,增强了系统抑制电力系统功率振荡的能力。
Flywheel type flexible power conditioner（FPC） is a novel FACTS device based on the flywheel energy storage.It has power exchanging characteristics between the FPC and the connected power system,which is able to change the power system damping.It is possible to suppress the power oscillation and enhance power system dynamic angular and voltage stabilities.The model of a single machine infinite-bus power system with a FPC is established in this paper.Then,the principle of FPC on damping out power oscillation is analyzed theoretically and a power controller is designed.The simulation results with EMTDC/PSCAD show very encouraging results of the FPC.A 10 kW prototype of FPC is experimented with power system.The FPC dynamic active power control capability significantly improves the damping characteristics,and the system dynamic stability is enhanced effectively in the system.
