摘要

The method to optimize the controller of dynamic reactive power compensation device is proposed by u-sing genetic algorithm. And the relation between damping adjustment of reactive power compensation device and maintaining of voltage regulation is analyzed. The genetic algorithm is used to optimize the parameters of the con-troller,and the optimal reactive power control instructions are selected,which ensures the stability of the voltage in the low damping oscillation. The simulation research is carried out in four machine two area system. That results show that the proposed method can suppress the power oscillation effectively and improve the stability of the system.%提出利用遗传算法优化动态无功补偿装置控制器的方法,分析了无功补偿装置阻尼调节和保持电压稳定的关系.通过遗传算法对控制器的相关参数进行协调优化,选取最优的无功控制指令,在阻尼低频振荡的同时保证了电压的稳定性.在四机二区域系统中进行了仿真研究,结果表明所提方法可以较好地抑制功率振荡,提高系统稳定性.
