AGC模式下300 MW火电机组协调控制系统的问题分析及优化

摘要

为了保障电力系统安全经济运行，有必要对机组负荷控制系统进行深入研究及优化。针对AGC考核指标，分析了300 MW火电机组负荷控制的典型问题，对控制策略和负荷设定值、机前压力设定、锅炉主控前馈等参数进行了优化，取得了较好的效果。%It is necessary to investigate and optimize load control system of units to guarantee the safe and e-conomical operation of power system. Aiming at AGC evaluation criteria , the paper analyzes typical problems of 300 MW thermal power units in load control. The control strategy and parameters such as load setting val-ue, throttle pressure setting and main control system of boiler are optimized, which achieved favorable effect.
