中文摘要:
      近年来基于电压源换流器(Voltage Source Converter, VSC)的高压直流输电(HVDC)技术发展迅速,为保证电网安全运行,经高压直流输电并网的风电场必须具备故障穿越能力。论文研究风电场经VSC-HVDC并网时的故障穿越能力,基于传统的耗能电阻电路,设计一种改进的耗能电阻拓扑结构,当电网侧发生故障时,结合风电机组进行协调控制,使得VSC-HVDC系统能够顺利平稳地穿越故障。最后,在PSCAD/EMTDC搭建基于VSC-HVDC的风电场并网模型,对所提出的方法进行仿真验证。#$NL关键词:故障穿越能力; 耗能电阻拓扑; 协调控制#$NL中图分类号:TM614
英文摘要:
      The technology of HVDC based on VSC developed rapidly in recent years. To ensure the safe operation of power grid, the fault-crossing capability has become a basic demand for wind farms connected by HVDC transmission. The paper researches on the fault-crossing capability of VSC-HVDC connected wind farm. Based on the traditional energy-dissipating resistance circuit, a new resistance topology is proposed. When the fault occurs on the grid side, coordinated control is carried out with wind turbines and new resistance topology, which makes the VSC-HVDC system cross the fault smoothly. Finally, the model of wind farm connected by VSC-HVDC is built in PSCAD/EMTDC and dynamic simulations are presented to assess the performance of the control method which is proposed.#$NLKeywords: fault-crossing ability; new resistance topology; coordinated control
