建于1958年的肖岭水库于1982年进行大坝加固加高,正常蓄水位提高2.6m,发电潜力大增,其下游梯级电站装机不合理,必需对其进行改造增容。将一级电站400kW机组与二级电站800kW机组对调,二级电站增加1台250kW机组。改造后梯级电站年平均售电量增加31.68％,改造成本2年内收回,经济效益显著。 Built in 1958, Xiao Ling Reservoir dam reinforcement and increase in 1982, the normal water level increased 2.6m, power generation potential greatly increased, its downstream cascade power station installed unreasonable, it is necessary to transform and compatibilize. The 400kW unit of a power plant will be adjusted to the 800kW unit of a secondary power station and a 250kW unit will be added to the secondary power station. After the transformation, the average sales volume of cascaded power plants increased by 31.68%. The reconstruction cost was recovered within 2 years and the economic benefits were remarkable.
