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

This
paper proposes an optimal control strategy for an HVdc light system
using a direct current vector control mechanism. The proposed
approach is compared with the traditional vector control
method for different HVdc control requirements, su

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
