基于梯级水电站实用的优化运行原则,综合考虑避免机组频繁启停、站间联合躲避机组振动区等因素,提出了一种新的梯级水电站 AGC 数学模型,包括机组开停机和站间负荷分配模型。较为详细地分析了该模型在清江梯级水电站 AGC 实现过程中必须考虑的工程化因素,在此基础上设计的 AGC 软件已成功地应用到清江梯级水电站中。
Based on the principle of optimal operation of cascaded hydropower stations, a new AGC mathematical model of cascaded hydropower stations is proposed considering the factors such as avoiding frequent start-stop of units and avoiding the unit joint avoidance of stations. The model consists of on-off and on-load models of units. The engineering factors that must be considered in the AGC implementation of the Qingjiang Cascade Hydropower Station are analyzed in detail. The AGC software designed on this basis has been successfully applied to the Qingjiang cascade hydropower stations.
