# 柔性直流输电系统的直接电流控制方法与仿真The Direct Current Control Method and Simulation of Flexible HVDC System

VSC-HVDC technology has small, efficient and flexible control characteristics and has become a hot spot gradually in transmit and distribute of electric power. The basis of the composition of the VSC-HVDC system structure and function are described, and established the precise mathematical model of VSC-HVDC under the dq rotating coor- dinate system, then proposed a direct current control strategy of the VSC-HVDC system, and built some different con- trol models and combinations which aim to the characteristics of the VSC-HVDC system. At last, the results of simula- tion shows that the proposed control strategy has a simple structure, excellent dynamic and stationary performance and successfully achieved the active and reactive power control independently.
