摘要
以定功率和定电压的方式来控制和实现高压直流输电系统的功率传输,根据高压直流输电的特性选择合适的控制方式。通过分析系统的数学模型,考虑影响系统稳定运行的因素,联系两者之间的相关性建立相应系统的微分方程,并搭建对应的仿真模型,设置一定时长的故障,验证定电流控制器对高压直流输电系统的正确性以及有效性。
The power transmission of HVDC transmission system is controlled and realized by constant power and constant voltage.The appropriate control method is selected according to the characteristics of HVDC transmission.By analyzing the mathematical model of the system,considering the factors affecting the stable operation of the system,the correlation between the two is established to establish the differential equation of the corresponding system,and the corresponding simulation model is built,and the fault of a certain period of time is set to verify the high voltage of the constant current controller.The correctness and effectiveness of the DC transmission system.
