风电潮流的波动会引起并网系统公共连接点（PCC）电压的波动。在基于电压源换流 器的高压直流输电（VSC-HVDC）交直流混合风电场并网系统中，控制VSC-HVDC 送端站注入 到PCC 点的无功功率可以抑制电压波动。本文讨论了VSC-HVDC 的无功功率控制器和定电压控制 器抑制电压波动的原理。基于电磁暂态软件PSCAD/EMTDC 建立了并网风电场模型、VSC-HVDC 模型及控制系统模型。仿真结果表明VSC-HVDC 采用定电压控制器的并网系统能更好的抑制电 压波动，采用

Focusing on the passive network, this paper analyzes the discrete mathematical model and its control strategy of the passive terminal of the VSC-HVDC system on the basis of the α-β frame of axes. The method of the functioning-fuzzy-subset inf

The fast control capability of the VSC-HVDC and the process of area mode oscillations are analyzed. An auxiliary fuzzy logic controller designed in Matlab for the Voltage Source Converter based HVDC transmission system, VSC-HVDC, to improve t

A hybrid fuzzy-PI controller for voltage source converter based HVDC (VSC-HVDC) transmission system is proposed in this paper. At first, the elementary model of VSCHVDC is described. Then the fuzzy self-tuning control strategy is proposed, in
