| 摘 要： | 对大规模风电接入电网将严重影响系统的稳态运行和动态特性的问题，结合风电特性，以某一实际风电场接入地区电网为例，计算和分析了某一片区电网中不同风电出力（0％、50％、100％）时各变电站的潮流和电压的变化情况，探讨和分析了当风场均为恒速恒频发电系统和等容量的火电厂两种情况时对系统功角稳定性影响。

| Abstract: | Based on large-scale wind power connected to the electricity grid will seriously affected the steady state and dynamic characteristic of system problems, this paper combined with wind power characteristics, exampled an actual wind farm access power grid. The change of power flow and voltage in the transformer substation were calculated and analyzed when a certain different wind power output （0%, 50% , 100% ） in a district power grid, the angle stability influence was respectively discussed and analyzed when wind power was constant speed and frequency electric system and the same capacity cold plants. |
