摘要
为消除电网中越来越多的谐波,运用瞬时无功功率理论的ip-iq法,采用DSP芯片作为控制核心实现系统数字控制,提高了补偿精度和运算能力,介绍了有源电力滤波器的硬件电路设计过程和软件设计流程图,并制作了实验装置。实验结果表明:谐波源负载的进线电源电流实现正弦化,验证了谐波检测算法的正确性和控制策略的有效性。
In order to eliminate more and more harmonic pollution in power system, using ip-iq instantaneous reactive power theory and DSP digital control system as control core, the compensation precision and the operational capability were increased. At the same time, the active power filter＇s hardware circuit design process and the software design were introduced, and the test sample was constructed. The experimental results indicated that the harmonic source load＇s current realized the sine, which had indicated that the harmonic examination algorithm and the control strategy were accuracy and validity.
