摘　　要：建立了基于dq同步旋转坐标系的轻型高压直流输电系统的状态空间模型,利用多时间尺度系统理论对模型进行了简化,分解出快慢子系统,并利用状态反馈,推导出基于多尺度模型的输出反馈控制策略,利用MATLAB进行仿真,并比较了简化前后模型的一致性,仿真结果表明,简化后的模型具有良好的精确性。An equivalent state-space model of HVDC Light system is presented under dq synchronous rotating coordinate system in this paper, After that, the simplified model based on the multi -time scale theory was given. The HVDC Light mathematical model is decomposed into the slow subsystems and fast ones in explicit form. Output feedback control strategy based on multi-time scale model is proposed by using state feedback. In the end, the coherency between the simplified model and composite ones is compared by MATLAB simulation, and the simulation resuh shows that the simplified model hased on multi-time scale has high accuracy
