| 中文摘要:为改善电动汽车充电站接入电网后引起的电压波动、无功不足等电能质量问题，提出了一种对电网进行无功补偿的控制策略。利用晶闸管投切电容器（TSC）无功补偿装置与模糊控制相结合，采用专家经验的方法，通过模糊控制器的双输入量来控制输出量，从而控制TSC的投切。仿真结果表明，通过该控制策略补偿后的电压维持在正常允许范围内，电网中所需的无功功率明显减少，且仿真速度加快。说明电动汽车充电站接入电网后TSC无功补偿的模糊控制控制策略有效、可行。 |

| Abstract:In order to improve the electric vehicle charging station connected to the electricity grid caused by the voltage fluctuation and the shortage of reactive power quality problems，this paper proposes a grid for reactive compensation control strategy. Conbining the thyristor switched capacitor (TSC) reactive power compensation device and fuzzy control，using the method of expert experience，output is under control through the double input and the cutting of the TSC will be controlled. Simulation results show that the voltage will maintain in the normal after the control strategy compensation，the required reactive power in power grid decreased significantly and the simulation will speed up，which means the strategy of fuzzy control is effective and feasible, |
