在研究电气化铁路谐波治理各种方案的基础上,提出了用于电气化铁路谐波治理的并联有源混合滤波方案及混合滤波器容量设计方法,并以某牵引变电所为例进行了容量设计.分析和计算结果表明,并联型混合滤波器中有源滤波器的容量只占单独采用有源滤波器方案的15.3%,占串联型混合滤波器中APF容量的65.4%.所以,本文提出的混合滤波器用于电气化铁路的谐波综合治理是可行的.

Harmonic suppression schemes for electrified railway with hybrid filter consisting of passive filter network and active filter in series-or parallel-connected configuration are discussed in this paper. A new hybrid filter topology and its capacity design method about APF, taking some traction substation as an example, are presented in the paper. The analysis and calculation results show that in the proposed hybrid filter, the converter in active filter, required to produce harmonic currents for compensation, has a rating of only 15.3% when compared with the converter rating in an active filter, and 65.4% of that in a series-hybrid filter. The proposed topology enables practical implement of active harmonic suppression for harmonic comprehensive compensation on electrified railways.
