【摘要】:针对同步旋转坐标系下的三相四线制LCL并联型有源电力滤波器控制技术的缺点,提出一种采用PR准比例谐振调节器的三相四线制LCL并联型有源电力滤波器的控制技术.该控制策略采用PR准比例谐振调节器控制三相四线制LCL并联型有源电力滤波器的电流输出,使三相补偿电流输出实时跟踪船舶上负载引起的谐波电流.针对PR准比例谐振调节器在谐振频率处有限增益导致的静差问题,定性地分析各个参数对三相补偿电流输出的控制精度与动态性能的影响并进行了MATLAB仿真实验.结果表明:采用三相四线制LCL并联型有源电力滤波器PR准比例谐振调节其控制,能够实现高精度电流补偿.
[Abstract]:For three-phase synchronous rotation coordinates LCL four wire shunt active power filter control technology shortcomings, proposed a control technique for a three-phase PR using the quasi proportional resonant regulator LCL four wire shunt active power filter. The output current control strategy based on PR quasi proportional resonant regulator to control the three-phase four wire system the LCL shunt active power filter, the harmonic current tracking ship three-phase compensation current output load caused by PR. According to the quasi proportional resonant regulator at the resonant frequency of the resulting finite gain problem of static error, the qualitative analysis of each parameter control precision and dynamic performance of the three-phase compensation current output effect and the the MATLAB simulation experiments. The results show that the three-phase four wire shunt active power filters LCL PR quasi proportional resonant control regulation, can achieve high precision current compensation.
