摘　　要：电力系统潮流计算是电力系统分析课程的难点和重点。采用仿真软件与实验台相结合的方式有助于学生对潮流分析理论的理解,提高学生学习兴趣,实现理论与实践的有机结合。先简单介绍了MatLab/Simulink软件、PSCAD软件以及PS-7G型实验台,然后以4机复杂电力系统为例,分别搭建了Simulink模型、PSCAD模型进行电力系统潮流仿真,并将结果与PS-7G型实验台实验结果进行对比。对比结果表明,电压电流的实验结果与Simulink、PSCAD仿真结果几乎一样;有功功率、无功功率方面,实验数据和仿真数据相差较大,PSCAD仿真结果更为粗略。Power flow calculation is the difficulty and emphasis of power system analysis course.In this paper,the combination of simulation software and experimental platform is helpful for students to understand the theory of power flow analysis,improve students'interest in learning,and realize the organic combination of theory and practice.This paper briefly introduces the MatLab/Simulink software,the PSCAD software and the PS-7G experiment table,then takes the 4-machine complex power system as an example,builds the simulink model and the PSCAD model respectively to carry on the power flow simulation of the power system,and compares with the experimental results of the PS-7G experiment table.The experimental results show that the experimental results of voltage and current are almost the same as those simulation of Simulink and PSCAD,but the experimental data and simulation data are quite different in terms of active power and reactive power.Especially the simulation results of PSCAD are more rough.
