【摘要】 电力系统分析综合程序 PSASP( Power System Analysis Software Package)是国内进行电力系统计算和仿真经常使用的软件 ,其结果也为大家所普遍接受。 Mathworks公司新近推出的MATLAB5.2中的 Power System Blockset( PSB)是专门为电力系统设计的仿真分析软件 ,其功能十分强大。文中对 3个电力系统典型模型的潮流和稳定分别进行了计算 ,分析表明这两种电力系统仿真软件得到的结果几乎完全相同 ,但也存在一定的差异 ,对其原因给出了初步的解释 ,并介绍了应用 MATLAB进行电力系统仿真时经常用到的一些方法、函数以及相关的工具箱更多还原

【Abstract】 PSASP (Power System Analysis Software Package) is applied widely in computation and simulation of powersystem. while recently PSB (Power System Blockset). powerful and flexible. is released as one of the blocksets ofMATLAB. The difference between the generator models. the transient power algorithms of PSASP and PSB are analyzed.The load flow and stability of three typical power system models are calculated and compared. The results obtained fromPSASP and MATLAB PSB show little difference. and the reason is explained. Those methods. functions and toolboxes usedfrequently in power system simulation by MATLAB are also introduced.This project is supported by National Natural Science Foundation of China (No. 59877011).更多还原
