摘要
简要分析了并联有源电力滤波器(APF)的工作原理。针对三相三线系统,且考虑电网电压畸变和不对称情况,给出一种基于滑动平均值原理的谐波检测法,以实现无功功率和谐波全补偿的控制策略。设计了基于DSP-CPLD的全数字控制系统,详细论述了系统硬件和软件的设计方案。实验结果验证了控制策略的正确性和设计的有效性。
The operating principle of the shunt aetive power filter is analyzed.A control strategy based on harmonic detection method of the sliding average is given in consideration of the source voltage becoming distorted and unbalanced, whieh can compensate the reaetive power and harmonics completely for three-phase three-wire system.A fully digital control system based on DSP and CPLD is designed and the system design including hardware and software is discussed.The experimental results show that the strategy is eorreet and the design is effeetive.
