摘　　要：城市负荷密度快速增长对城市配电网供电能力及电能质量要求不断提高,以交流输电为主的城市配电网发展面临越来越大的困难和挑战,柔性直流输电技术必将成为解决城市配电网发展的有效途径之一。本文在等效的符合受端电网性质的城市配电网模型的基础上构建含有柔性直流输电线路的城市配电网模型,利用PSCAD/EMTDC对柔性直流输电在城市配电网中应用的静态稳定性及暂态稳定性进行仿真分析,仿真表明柔性直流输电技术在城市配电网中对于提供无功电压支撑改善电压稳定性等方面能发挥积极的作用,具有良好的应用前景。Fast growth of the city 10ad density asks for higher capability of power supplying and improved performance of urban distribution network. The development of AC power distribution network is facing more and more difficulties and challenges, and VSC HVDC technology will become one of the effective ways to＂ solve the urban distribution network development. This paper builds in PSCAD/EMTDC a urban distribution network including a VSC transmission line with the property of receiving end, based on the equivalent urban distribution network model. A serials of simulation tests, including stability and transient stability simulation analysis, verify the positive functions at the aspects of voltage support the technology brings.
