摘　　要：为了满足“两个细则”的要求以及充分调动水电厂提供调频辅助服务的积极性,对水电厂自动发电控制(AGC)策略中与调节性能关系密切的部分进行分析与设计,在保证机组安全性的前提下,通过对影响水电厂AGC的因素进行分析,引入与机组调节速率和调节精度相关的控制条件,在经济性目标的基础上加入参加AGC调节的机组数量最少的目标,建立水电厂AGC最优控制策略模型,确保水电厂机组AGC调节性能在电网考核合格的范围内,有效减少水电厂AGC的考核电量,保证水电厂AGC的调节品质并提高经济性。仿真结果验证了所提策略的有效性。In order to meet the requirements of “two rules” and fully mobilize the enthusiasm of hydropower plant to provide frequency regulation auxiliary service,the parts closely related to regulation performance in automatic generation control(AGC) strategy of hydropower plant are analyzed and designed. On the premise of ensuring the safety of the units,the control conditions related to the unit regulation rate and regulation accuracy are introduced through the analysis of the factors affecting AGC of hydropower plant. On the basis of economy object,the object of minimum number of units participating in AGC adjustment is added,an optimal control strategy model of AGC for hydropower plant is built,which ensures AGC regulation performance of units in hydropower plant within the range of qualified power grid assessment,effectively reduces the assessment power quantity of AGC for hydropower plant,and ensures the regulation quality of AGC for hydropower plant and improve the economy. The effectiveness of the proposed strategy is verified by the simulative results.
