水电站AGC中负荷调节策略的研究

A Study on Load Regulation Strategy for AGC of Hydropower Stations

在水电站 AGC中采用了一种新的负荷调节策略 .AGC的负荷设定值直接下达给调速器 ,避免了脉冲设定方式的不足 ;采用过渡分配方案 ,避免了大负荷调节时出现电站出力缺额和小负荷波动时机组频繁调节 .实际应用验证了算法的有效性 .

This paper presents a new load regulation strategy for the AGC of hydropower stations. The load set point given by AGC is given to turbine governors directly, with which the shortcoming due to pulse setting can be overcome. An interim load dispatching program is used so as to avert a shortage of plant power output when a large load regulation happens, or a frequent regulation of turbine set when the load fluctuates in a smaller scale. Practical applications of new strategy proposed verify its effectiveness.
