摘要
糯扎渡水电站水库总库容237.03亿m^3,蓄水后形成澜沧江流域最大水库,使上下游水体水温较天然河道发生改变。根据环评批复要求,糯扎渡水电在建设期通过电站进水口分层取水研究,预测了水库水温结构和分布,在电站投运后开展了水库垂向水温的持续监测,验证了水库水温数值预测结果。对比分析了水库坝前垂向水温预测与实测数据,为进一步修订和完善电站进水口分层取水叠梁门运行调度方式奠定了基础。
The total reservoir capacity of Nuozhadu Hydropower Station is 23. 703 billion m^3. The impoundment of reservoir will form the largest reservoir in Lancang River Basin and make the water tmnperature change greatly than natural river. According to EIA approval, the structure and distribution of reservoir water temperature should be predicted by studying intake stratified water diversion in construction period of station, and the vertical water temperature after power station put into operation should be continuously monitored to verify the results of prediction. The forecast and measurement data of vertical water temperature are comparatively analyzed herein, which provide a basis to improve the operation of stoplog gate for stratified water diversion of station.
