摘要
论述了一种应用到串联补偿装置(Thyristor Controlled Series Compensation,TCSC)的阻抗控制模型预测控制算法(Model Predictive Control,MPC)。建立了含TCSC的Phillips-Heffron模型,通过分析模型预测控制算法的原理,论证出其在TCSC阻抗控制中的可行性,并且建立了对TCSC阻抗进行MPC控制的模型。在4机双区域系统中进行仿真,仿真结果表明:此种控制算法和传统的控制算法相比,能够较快调节TCSC的容抗,增加系统阻尼,改善系统的稳定性。
This paper introduces a Model Predictive Control （MPC） algorithm for Thyristor Controlled Series Compensation （TCSC）to improve the power system stability. The model of Phillips-Heffron with TCSC is established, and the feasibility of its application in the reactance control of the TCSC is demonstrated in the light of the principles of the MPC algorithm. A model to control the TCSC reactance with MPC is also established. Sinmlation of the algorithm is conducted in a four-machine two-area system. The result of the computer simulation shows that, compared with the traditional algorithm, the proposed one can quickly regulate the impedance of the transmission line, increases the damp of the power system, and therefore improves the stability of the power system.
