摘要
本文把网络的分块射影法用于大规模电力系统不对称短路的分析计算。研究表明：该方法对短路计算是可行的。一旦求出了射影张量，即可重复用于后续的计算，只需改变故障所在的那一个子网络的射影张量。本文提出的网络分块射影算法为大规模电力系统的分析计算提供了一条崭新的途径。
In this paper, the projective method isapplied to piecewise solution of unsymmetrical shortcircuit in large-scale power systems.A brief descrip-tion of the projective theory of networks is first given,then the projective piecewise algorithm for short cir-cuit calculation is presented in detail.Results showthat the method presented is effective,reliable and so-phisticated for short circuit analysis. Once the projec-tive tensors of subnetworks are found,they can beused repeatedly in subsequent computations. Only oneprojective tensor of subnetwork in which the fault hap-pens,should be modified.The projective piecewise so-lution provides a new way for the analysis and compu-tation in large power system.
