摘　　要：针对当前电力系统分析程序存在差异的问题,从潮流计算角度,对比研究了国内目前使用较为普遍的2款潮流计算程序(PSAT和PSD-BPA),分析了收敛误差、发电机分接头、负荷比例等不同初值条件设置对其潮流计算结果的影响。分析结果表明:PSAT在建模、可视化和自定义方面具有一定优势,比较适合小规模电网仿真和自定义元件模型研究;而BPA的计算速度快,计算精度高,比较适合大规模电网仿真。Aiming at the problem of the current power system analysis program existing differences, from the point of view of power flow calculation, contrasts and studies the two commonly used software programs （PSAT ＆ BPA） in china, analyzes different initial conditions, such as convergence error, the generator tap settings and load ratio, have different influence on the result of power flow. The analysis result shows that PSAT has certain advantage in modeling visualization and user-defined, is suitable for small-scale power system simulation and user-defined model research; But BPA has fast calculation speed and high calculation accuracy, is suitable for large- scale power system simulation.
