摘要
对于具有较大调节库容水头变幅大的水电站期望能采用较低的额定水头,以减少受阻容量。而从混流式水轮机稳定运行的要求出发,希望额定水头不低于Hmax1.15。为此,应兼顾二者的要求合理选择水轮机的额定水头,糯扎渡水电站水轮机的额定水头选择187m较为合适。
For the power station of large balancing storage and width head range, the low rated head is expected to reduce the suffocate capacity. For the operation stabilization of Francis turbine, the rated head not less than Hmax1.15 is expected. The suitable and reasonable water turbine parameter shall be selected for both of the reasons above-mentioned.
