摘 要: 针对高压直流(HVDC)系统直流(DC)侧谐波抑制的要求,提出了一种新型混合滤波系统:并联无源滤波器和串联小容量电抗———变压器耦合有源直流滤波器。讨论了混合型滤波器的谐波补偿原理及其控制方案,并给出了混合型滤波器抑制谐波的模拟仿真曲线。 For requirements of suppressing harmonics on the dc side of HVDC system,a new hybrid filtering system a shunt passive and a small rated reactor transformer coupling series active filter is presented,and the harmonic compensation and control principles are discussed theoretically in this paper.Digital simulation results show excellent filtering characteristics of harmonic current and very high performance/cost by using a new hybrid filtering system proposed int this paper.
