摘要

大规模风电通过特高压直流(UHVDC)系统传输时，因换相失效、直流阻塞等事件引起的暂态过电压(TOV)问题严重影响了系统的安全运行，制约了输电能力。准确的系统建模是分析系统暂态过电压特性的基础。本文对系统主要组成部分，特别是特高压直流输电线路和大型风电集群的建模方法进行了详细的梳理。综述了各种建模方法的优缺点。为未来大型风电接入特高压直流系统建模提出了可行的优化方案。

Review on Modeling Methods of Large-Scale Wind Power Connected UHVDC Systems

When large-scale wind power is transmitted through ultra-high voltage direct current (UHVDC) system, transient overvoltage (TOV) problems caused by events such as commutation failure and DC blocking seriously affect the safe operation of the system and constrain the power transmission capacity. Accurate modeling of the system is the basis for analyzing the transient overvoltage characteristics of the system. In this paper, the modeling methods of the main components of the system, especially UHVDC transmission line and large-scale wind power cluster, were sorted out in detail. The advantages and disadvantages of various modeling methods were reviewed. Feasible optimization schemes were proposed for future modeling of large-scale wind power connected UHVDC system.
