摘　　要：基于DIgSILENT/Power Factory仿真平台建立了新疆某地区含风电场的电力系统仿真模型,以电压和频率两个电气量作为动态约束条件,通过对风电场的穿透功率极限的计算和仿真,确定了该地区电网的风电场最大可接入容量。研究结果表明:采用频率约束法计算和时域仿真分析相结合确定的风电场最大可接入容量,能保证风电系统的稳定运行;并且优化影响风电系统稳定运行的因素和不同约束条件,对确定系统的风电场最大可接入容量和风电场的设计、运行和规划都有重要意义。In this paper,a simulation model of power system with wind farm in some area of Xinjiang is established based on the DIgSILENT/Power Factory simulation platform.The wind power penetration limit is calculated and simulated with voltage and frequency being considered as dynamic constraints,and then the maximum access capacity of wind power plant of Xinjiang is determined.Research results show that the maximum access capacity of wind farm that determined by the combination of the frequency restriction and the time simulation can ensure the stability of wind power system.Besides,the optimization of some factors and other security constraints play a significant role in determining the maximum access capacity of wind farm and its designing,operating and planning.
