摘要
以中海油文昌柔性直流输电系统向无源网络供电为例,搭建了PSCAD/EMTDC环境的系统仿真模型,在整流侧采用定直流电压控制、逆变侧采用定交流电压控制的方式下,分别针对逆变侧负载接入和逆变侧负荷变化进行仿真。结果表明,在所采用的控制方式下该柔性直流输电系统能够稳定地运行。
Taking the CNOOC Wenchang VSC-HVDC transmission system for supplying power to a passive network as an example,and establishing a simulation model for the system in the PSCAD/EMTDC environment,this paper makes simulations on the load access and load changes at the inverter side in the control condition of fixed DC voltage at the rectifier side and fixed AC voltage at the inverer side.The results show that the VSC-HVDC system can stably operate in the control condition.
