通过介绍高压直流输电系统的基本结构和工作原理,利用Matlab的电力系统模块库(PSB)建立交直流混合输电系统的仿真模型,并利用Matlab/Simulink仿真了所建模型系统直流线路对地短路时的暂态过程;对所建模型系统交直流侧发生故障的暂态过程进行仿真,得到该模型的动态响应曲线,并对仿真结果进行分析.实践证明,所建模型和仿真方法有效、直观、省时.
The basic structure and basic principle of HVDC power transmission system are introduced briefly. Then, using power system blockset （PSB） of Matlab,a simulation model for AC and DC hybrid transmission system is built, and using Matlab/Simulink to simulate the transient state processes of this system when the short circuit faults to ground occur on DC line. It is proved by simulation result that model and the simulating method is validity, visual and saves time. Moreover, under the Simulink environment of Matlab, the system is adopted to stimulate fault detection and clearance for both AC and DC, the dynamic response curve of the mode and analyzed result is attained.
