| 摘 要： | 研究了电力系统低频振荡及其产生机理,并理论分析了静止同步串联补偿器(SSSC)对抑制电力系统低频振荡的作用。建立包含SSSC的单机无穷大系统的数学模型,推导该模型的非线性动态方程。利用在稳定运行点线性化的方法,以SSSC输出电压的相角和幅值调制系数为控制变量,设计了SSSC的暂态控制器,并将其用于提高系统阻尼,抑制电力系统低频振荡。在Matlab/Simulink中搭建包含SSSC的单机无穷大系统及暂态控制器的模型进行仿真验证,结果表明理论分析的正确性以及所提出的暂态控制策略的有效性。

| Abstract: | The paper discusses the low frequency oscillation in power system and its mechanism,theoretically analyzes the damping effect of static synchronous series compensator （SSSC）on power system low frequency oscillation theoretically,establishes the mathematical model of single machine infinite bus system with SSSC,and deduces the nonlinear dynamic equations of the model.By using linearization at the stable operating point,taking both the phase angle of output voltage and amplitude modulation factor of SSSC as control variables,a transient stability controller of SSSC is built to improve system damping and suppress the power system low frequency oscillation.The model of the single machine infinite bus system with SSSC and the transient stability controller are built in MATLAB/Simulink to carry out the simulation.The results show that the correctness of the theoretical analysis and the effectiveness of the transient control strategy. |
