摘　　要：云南电网实现异步联网后,频率稳定问题将取代功角稳定成为云南电网最主要的问题,大扰动下风电场因频率越限有无序脱网的风险。本文利用BPA仿真软件,将风电场脱网对系统频率影响的机理进行分析,结合云南风电场频率特性定值调查结果,评估其对电网频率稳定影响,并提出应对措施。After Yunnan power grid asynchronous interconnection,the frequency stability will have become the most important issue in Yunnan Power Grid replacing angle stability.wind far ms may be Escape the power gred disorderly due to frequency exceeding the limit when a large disturbance occurring.In this paper,the principle how wind far ms off-grid affect system frequency will be finded by BPA simulation software.Combined with the frequency characteristics of Yunnan wind far ms,assess their impact for the grid frequency stability,and provide a reference for the testing and operation of asynchronous Interconnection of Yunnan grid.
