摘　　要：为掌握海南电网的频率特性,以作为采取相关措施确保电网安全稳定和经济运行的基础,对海南电网2008年的历次机组跳闸和负荷损失事故进行了分析,掌握了海南电网频率偏差系数的分布规律,校核分析了海南电网有关计算模型的有效性,对于机组一次调频的管理、联网后联络线功率控制的影响因素以及联网后自动发电控制(automatic generation control,AGC)的有关参数提出了建议。To understand the frequency characteristics during isolated operation of Hainan Power Grid, and to estabilish the basis for taking measures to ensure safe and economical operation, the generator-sheding and load-losing accidents of Hainan Power Grid in 2008 are studied, and the distribution of the frequency coefficient of the grid is discovered. The effectiveness of mathematical models is analyzed, suggestions on generator unit regulation, factors affecting power control when interconnecting with China Southern Power Grid （CSG）, and the automatic generation control （AGC） parameters for interconnecting with CSG are proposed.
