| Abstract: | Based on the basic principle of continuation power flow and the analysis demands of voltage static stability,some applied models of continuation power flow,for instance,loading models,fault models and branch type models were developed.Besides,this paper discusses realization methods of some key technologies,for example,parameter selection,step control,load change mode and identification of critical point.The changes of voltage were investigated when load,generators and circuits changed so as to describe exa... |
