摘　　要：以美国西部电网WSCC 3机9节点系统为例,基于MATLAB/Simulink和PQ潮流算法搭建3机9节点电力系统模型,观察各母线节点电压的幅值、相角以及有功功率和无功功率。仿真结果表明:两种方法的测量差值很小,可视为一致。由此可见,M文件编程正确,两种仿真方法均可进行潮流计算仿真。Taking the 3-machine 9-node system of the WSCC in the western United States power grid as an example,the model of the 3-machine 9-node power system is built based on the MATLAB/Simulink and PQ power flow algorithm,and the amplitude,phase angle,active power and reactive power of each bus node are observed.The simulation results show that the measurement difference between the two methods is very small and can be regarded as consistent.From this,we can see that M file programming is correct,both simulation methods can carry out power flow calculation simulation.
