摘要
主要采用新型正负d-q控制系统来产生PWM实行对并联混合型有源电力滤波器(PHAPF)的控制。不仅将有源电力滤波器(APF)与无源滤波器(PPF)串联的PHAPF更好地结合,而且还发挥了PPF和APF造价较低、性能优良等优点。主电路与控制电路的良好结合能以较小的有源装置容量实现大容量的谐波补偿,并能迅速、直接、准确、有效地抑制谐波,将耐压量较低的半导体器件安全地用于高压系统的谐波补偿中,在有良好滤波效果的同时还有效地补偿了无功分量,具有广阔的发展、应用前景。
Active power fiher（APF） and passive power filter （PPF） series of PHAPF are combined perfectly, and the low cost, good performance and other characteristics of PPF and APF are exerted.The combination between main circuit and control circuit can realize large capacity harmonic compensation from small active power device capacity, and it can quickly,directly,accurately and effectively restrain harmonics.The semiconductor has a low amount of press wrization is safely used in the harmonic compensation of high voltage system, and it has a well filtering effect, meanwhile, the reactive power components are filtering also effectively compensated.
