目前国内单机容量最大的混流式水轮机——龙羊峡水电站HLD06_A-LJ-600水轮机已于1987年“十一”顺利投产运行.从运行效果来看,机组运行稳定,出力富裕,温升正常,可以达到预测指标.当然,要真正提出水轮机的各项确切数据,尚须进行水轮机的效率及稳定性试验.另外,由于龙羊峡水库总库容247亿m~3,预计要到1995年才能蓄到设计正常高水位2600m.因此,龙羊峡水轮机初期将在水头90m左右运行较长时间,特别是今冬明春,由于下游灌溉用水要求,水库将放空到死水位2530m左右,此时水轮机运行性能如何,是一个引
At present, the HLD06_A-LJ-600 turbine with the largest stand-alone capacity in Longyangxia Hydropower Station was smoothly put into operation in “Eleventh” in 1987. From the operational effect point of view, the unit ran steadily with rich output and normal temperature rise, Of course, to really put forward the exact data of the turbine, the turbine efficiency and stability test still need to be carried out.In addition, due to the total storage capacity of 24.7 billion m ~ 3 Longyangxia Reservoir is expected to be in 1995 to save To the design of the normal high water level 2600m. Therefore, the initial Longyangxia turbine head 90m will run for a long time, especially this winter and next spring, due to the downstream irrigation water requirements, the reservoir will be empty to the dead water 2530m or so, at this time the turbine performance How, is a guide
