静止同步串联补偿器附加阻尼控制器设计方法

摘要

为了提高静止同步串联补偿器抑制阻尼振荡能力,从装置参数方面研究了阻尼控制器设计方法,并设计了控制器结构.在对补偿器工作机理的研究基础上,分析SSSC对系统电磁转矩的贡献,量化地得出补偿器控制器参数对系统阻尼转矩影响的数学模型,以此来指导补偿器附加阻尼控制器的设计.原理分析表明补偿器直流电压控制与注入交流电压控制对系统阻尼转矩的作用是相反的.通过相位补偿法设计了补偿器的附加阻尼控制器,仿真分析证明了所设计的控制器在补偿器的任何投入方式下都具有适应性和有效性.%To improve the static synchronous series compensator (SSSC) damping oscillation suppression capabilities, the damping controller design method is discussed and controller structure is designed from the aspect of device parameters. Through an in-depth analysis of Static Synchronous Series Compensator Mechanism and its contribution to the electromagnetic torgue, the parameters of the controller is quantified to draw the mathmatical model for its system influence on the damping torque, in order to guide the compensator supplementary damping controller design. Analysis shows that the compensation principle of the DC voltage and the injected AC voltage control have opposite effects on the damping torque. The paper introduces the phase compensation method of additional compensation damping controllers. Simulation analysis shows that the controller has flexibility and effectiveness in any way of compensation.
