摘要
超高压输电线路和电力供配电系统对电力系统的安全稳定运行影响极大。设计使用MATLAB/Simulink电力系统工具箱搭建超高压输电线路和无限大功率供配电系统仿真模型,在仿真模型下对系统发生三相短路和不对称短路故障时的故障特征量以及出现的序分量特征量进行分析,仿真结果验证了系统模型的正确性,可以作为系统发生短路故障分析的依据。
EHV transmission lines and power supply and distribution systems have great influence on the safe and stable operation of power systems.MATLAB/Simulink Power System toolbox is used to build the simulation model of EHV transmission line and infinite power supply and distribution system,under the simulation model,the fault characteristics and the order component characteristics of three-phase short-circuit and asymmetric short-circuit faults are analyzed.The simulation results verify the correctness of the system model,it can be used as the basis of system short-circuit fault analysis.
