摘　　要：自动发电控制是控制系统频率和区域间联络线交换功率按计划运行的重要手段,频率偏差系数B的选择对于控制系统稳定和频率恢复起着至关重要的作用,理想状况是将区域的频率偏差系数设置得与本区域的自然频率特性相等。介绍了动态系数法的基本原理,以及将其引入华东电网需要解决的技术问题。分析表明将动态系数法引入华东电网有助于提高华东电网的频率质量,改善系统的频率控制特性。The Automatic Generation Control （ AGC ） is an important means to keep the system frequency and crossregional tie-line power exchange operation as planned. The selection of the frequency bias coefficient β is of the most importance to system stability and frequency recovery, and the ideal situation is to set β the same as the natural frequency of the local area. The basic theory of the dynamic coefficient method is presented, as well as technical problems that need to be solved in order to introduce the method to East China Power Grid. Analysis shows that the method can help improve the frequency quality of the Grid and the frequency control charactersitics of the system.
