摘　　要：在华东电网发电机和励磁系统建模及参数实测工作取得的成果的基础上,对2004年4月8日黄渡站5101线单相接地故障试验进行了潮流、短路电流和暂态稳定仿真计算,分析了发电机、励磁系统、PSS、负荷等模型和参数对电网动态特性仿真的影响,研究结论对开展华东电网计算用模型参数的校核工作,提高电网的仿真分析水平将有所帮助。Based on the modeling of generators and excitation systems tor East China Power Grid, as well as the achievements on parameter measurement, simulation calculations on power flow, short-circuit current, and transient stahility are conducted for the single-phase ground fault occurred on 5101 line of Huangdu Substation on April 8 of 2004. The influences of models and parameters of generators, excitation systems, PSS, and loads on the dynamic characteristic simulation of the Grid are analyzed, with the conclusions helpfid to check calculation models and parameters, and to improve the simulation analysis level of the Grid.
