摘　　要：介绍阳逻电厂自动发电控制(AGC)系统,重点分析了机炉协调控制系统的特点,并给出AGC系统的调试经验。试验表明,负荷指令变化速率是功率偏差和主蒸汽压力偏差的主要影响因素,适当增大锅炉侧控制器动态前馈的补偿,有助于减少偏差。此外,负荷指令变化速率也对锅炉燃烧效率有较大影响。The automatic generation control (AGC)system in Yangluo Power Plant has been presented,emphatically analysing the features of turbine-boiler coordinated control system,and giving the experience of debugging the AGC system. Tests show that the variation rate of load command is the main factor affecting the power deviation and the main steam pressure deviation,it is helpful for decreasing the said deviations to properly increase the compensation of dynamic feed-forward for the boiler side controller .In addition,the variation rate of load command also has comparatively large influence upon combustion efficiency of the boiler.
