摘要:有源電力濾波器(APF)越來越廣泛的運(yùn)用在電力系統(tǒng)中,用來補(bǔ)償諧波和無功。本文對基于DQ旋轉(zhuǎn)坐標(biāo)系的無差控制方法,提出了“DSP+FPGA”的控制系統(tǒng),克服了單DSP運(yùn)算能力不足的缺點(diǎn),實(shí)現(xiàn)了補(bǔ)償25次以內(nèi)諧波電流的功能。實(shí)驗表明,該控制系統(tǒng)能實(shí)現(xiàn)DQ旋轉(zhuǎn)變換對計算量的要求。使用該控制系統(tǒng),APF已經(jīng)實(shí)現(xiàn)了單獨(dú)補(bǔ)償25次以內(nèi)諧波電流的功能,補(bǔ)償效果顯著。

Abstract:Active Power Filter has been widely used in electrical systems for harmonic suppression and reactive power compensation. This article presents the DSP+FPGA control system based on the algorithm with little static misadjustment by DQ rotating frame, thus avoiding the disadvantages of DSP that lacks operational ability and in the meantime realizing the function of compensating harmonic current within 25 times. Experiments tell that this system can meet the requirements for computation quantity due to the conversion of DQ rotating. With this system, APF has solely realized the function of compensating harmonic current within 25 times, which is quite effective.
