摘　　要：研究了基于多端电压源型换流器高压直流输电的风电场联网控制策略。采用基于反馈线性化的非线性解耦方法,针对系统侧换流器,提出了简化的输入输出线性化(SIOL)的控制策略。SIOL以直流电压和无功功率作为控制目标。采用Matlab/Simulink软件进行了仿真,比较了基于小信号分析的线性解耦控制和SIOL的控制效果。仿真结果表明,SIOL的控制效果优于线性控制。Multi-terminal voltage source based HVDC is utilized to interconnect wind farms. The paper addresses control strategies for interconnecting wind farms to grids. Two control strategies are presented, namely, small signal analysis based linear decoupling control and simplified input-output linearization （SIOL）, which are applied to transmitting wind power to utility grids. Simulation is performed using Matlab/Simulink to validate the strategies. The two control strategies are compared. The simulation results demonstrate that SIOL has better performance than its linear counterpart.
