【Abstract】 First, 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 the typical 6-pulse bridge HVDC power transmission system is built, and using MATLAB/Simulink to simulate the transient 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 and visual and saves time.更多还原
