摘　　要：陶岔电站自2018年7月投入运行以来,总累计发电量约12.6亿kW·h,发挥了较大的经济效益,但在实际运行中需要进行机组停机检修,会对发电效益产生一定的影响。通过计算机组检修期间损失的发电量,绘制相应趋势图,分析机组检修期间发电量损失与上游库水位和入渠流量等因素之间的关系,提出有利的机组检修时机,可提高机组发电效益。Since the power station was put into operation in July 2018,its total cumulative power generation has been about 820 million kW.h,which has brought great economic benefits.However,in actual operation,it is necessary to carry out unit shutdown and maintenance,which will have a certain impact on power generation benefits.In this paper,the corresponding trend chart is drawn by calculating the loss of power generation during the maintenance of the unit,and the relationship between the loss of power generation during the maintenance of the unit and the factors such as the upstream reservoir water level and the inflow of the channel is analyzed.The favorable opportunity for unit maintenance can improve the efficiency of unit power generation.
