摘　　要：随着电力电子器件的发展,特高压的直流输电相继问世。本文以电压源性逆变器为原理并采用PMW调制方式,搭建1k V柔性高压直流输电一次电路和对应控制部分的simulink模型,通过矢量控制的原理实现PQ解耦控制,通过采用PI调节器最终实现无静差控制,通过分析仿真后的结果说明该系统传送的有功P和无功Q能够实时跟随给定参考的有功和无功,动态性能良好,最后通过仿真结果进行了谐波分析,基本满足标准。With the development of power electronic devices, the HVDC transmission field. Based on inverter of voltage source sex principle and PMW modulation method is adopted to build 1 kV flexible HVDC power transmission circuit and corresponding control part of the simulink model, PQ decoupling control was achieved by the principle of vector control, controlled by PI regulators eventually astatic, through the analysis of the results of simulation show that the system can transmit the active and reactive power Q P in real time with a given reference active and reactive power, good dynamic performance, finally, the simulation results for the harmonic analysis, basic meet the standard.
