| 摘 要： | 针对现有有源电力滤波器结构较为复杂、谐波电流跟踪困难等问题,提出了一种新型有源电力滤波器电流控制策略。该控制策略不需要进行负载电流测量与谐波检测,而是直接在电网侧提取电网电流,并将比例积分与矢量比例积分控制器结合使用以对电网电流进行控制,从而实现谐波补偿。仿真结果证明了该策略的正确性与有效性。

Research of a novel current control strategy for active power filters |

| Abstract: | In view of problem of complex structure and tracking difficulty of harmonic current of existing active power filter,a novel current control strategy of active power filter was proposed.The control strategy does not need load current measurement and harmonic detector,but directly extracts harmonic component at the supply side,and combines with conventional proportional-integral and vector proportional-integral controllers to control current of power gird,so as to realize harmonic compensation.Simulation results demonstrate correctness and validity of the strategy. |
