Abstract
This paper summarized the three-phase voltage unbalance of Guangxi Super Express and ordinary electrified railway by the Guangxi intelligent electric quality monitoring system' data and the field-testing results:The three-phase voltage unbalance of PCC along the substations meets the national standard before and after Super Express being put into service.The PCC three-phase voltage unbalance rises after being put into service.The three-phase voltage unbalance of Super Express is smaller than ordinary electrified railway.Then,the harms of three-phase voltage imbalance were analysed and the suppression methods were given.Combined with Zhentianqian's questions the method of adjusting three-phase voltage unbalance through reactive power compensation device was tested by ETAP simulation.It is pointed out that the unbalance of the three-phase voltage can be effectively reduced by installing capacitors between different phases.关键词
