摘　　要：本文提出一种用并联电容来实现三相不对称星形负载电路取代中线的方法,即给其中的两相负载上并联适当大小的电容以达到省去中线的方法。在此基础上还研究了给三相负载都并联电容以进一步优化电路,使三相负载总的无功功率为零。This paper presents a new approach to omit the neutral line of the asymmetrical Y-connected three-phase loads. The method that makes two-phase loads parallel appropriate capacitors is presented. Since then, we also study to three-phase loads capacitors in parallel to solve the optimization of the circuits further and finally achieve the total reactive power of three-phase loads is zero.
