摘　　要：提出了不对称三相系统故障分析的新算法，该算法直接利用三相潮流计算时所形成的节点导纳阵因子表，实现了潮流，故障计算的有机结合。故障计算时还充分利用了近年来发展的稀疏补偿法和稀疏向量法，从而进一步提高了计算速度。An asymmetrical three phase load flow method Lmplicit Z-BUS Matrix method with symmetri-cal components is proposed herein,The convergence characteristic of the method is analyzed,In this paper,a generalized asymmetrical three phase power system fault analysis method iS presented,which does′t needto reform the system admittance and its factor and can use the factor of load flow computation. So powerflow computation and fault analysis can be interfaced effieiently,In the methoud,Sparsity-Oriented compen-sation Method and Sparse Vector Method have also been used,and the computation speed is further im-proved.
