摘　　要：通过瞬时功率平衡原理得到了有功损耗电流与直流电压波动的关系,通过基尔霍夫电流定律得到了直流侧上下电容电压差与不平衡电流的关系。根据电压控制性能指标所设计的串联PI环节校正装置参数,最后在PSCAD/EMTDC中仿真证明了所提出直流侧电压控制方法的可行性。The passage has obtained the relation between power loss current and direct-side voltage through instant power balance principle,and also obtained the relation between direct-side up and down capacitor voltage error and unbalanced current through kirchhoff ＇ s law.According to the designed series PI component parameter of voltage control performance target,the passage has proved the feasibility of proposed direct-side voltage control method in PSCAD/EMTDC.
