摘要

In this paper,HVDC (High Voltage Direct Current) transmission system simulation model is built based on the MATLAB/Simulink platform and following the control rule of HVDC system.Then the system performance simulation was conducted under different fault based on this model.It is proved that HVDC system simulation model is consistent with the real operating system,and the performance of this simulation system model under determinate fault conform to the theoretical prediction.The study is of practical significance to guide the real system application.%基于MATLAB/Simulink仿真平台、依据高压直流输电的控制规律,建立高压直流输电控制系统的仿真模型,并在模型的基础上进行换流器控制规律仿真及故障仿真.仿真结果表明,建立的模型与实际系统的运行相一致,故障仿真结果符合理论预测,对指导高压直流输电的实际应用有重要意义.
