摘要
针对电动汽车充电站投运后引起的电能质量问题,提出用静止无功补偿器和有源电力滤波器(APF)组成的联合系统来治理。分析了电动汽车充电站投运后产生的电能质量问题。采用了一种基于广义积分器的新型广义积分迭代控制算法。与常规的PI控制相比,该算法计算量小,能够对特定次数的谐波进行分频控制,实现对特定次谐波的补偿。最后利用Matlab软件进行仿真并搭建试验平台,试验结果验证了联合系统的有效性和可行性。
For power quality problems caused by electric vehicle charging stations,this paper proposed a static vat compensator and active power filter （ APF ） system to govern power quality. The power quality problems for electric vehicle charging stations were analyzed. A novel iterative generalized integrator control algorithm was proposed. Compared with the conventional PI control method, the algorithm has small calculated amount, and can divide control for a specific number of harmonics to achieve the specific harmonic compensation. Finally, the simulation was carried on by using Matlab software, and the experimental platform was set up. The simulation and experimental results verify that the combined system is effective and feasible.
