| Abstract: | 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 result shows that the simplified model based on multi-time scale has high accuracy. |
