Three Gorges Hydropower Station's turbines with 700 MW of unit capacity is one of turbines with the largest unit capacity in the world. But,its operation conditions are more complicated than those of ones having commissioned with the same unit capacity. The complexities mainly include that the varying amplitude of turbine's operation head is very large, ranging from 61 m to 113 m, exceeding one of turbines having commissioned with more than 500 MW of unit capacity; that the time for which the turbines...

Three Gorges Hydropower Station's turbines with 700 MW of unit capacity is one of turbines with the largest unit capacity in the world. But,its operation conditions are more complicated than those of ones having commissioned with the same unit capacity. The complexities mainly include that the varying amplitude of turbine's operation head is very large, ranging from 61 m to 113 m, exceeding one of turbines having commissioned with more than 500 MW of unit capacity; that the time for which the turbines operate under high head zone of 105~110 m is comparatively long, and so is under low head zone of 75~80 m;that the turbines must accommodate both early generating pool level and final design pool level conditions; and that the turbines must also accommodate both large water quantity /high sediment concentration conditions during flood period and small water quantity / low sediment 'concentration conditions during non flood period' For above technical features of Three Gorges Hydropower Station's turbines, a number of technical requirements for them have been suggested.

单机容量700兆瓦的三峡水轮机,是世界上最大容量的水轮机之一,但比已投入运行的700兆瓦水轮机运行条件更为复杂,主要体现在水轮机运行水头变幅最大,达61~113m之间,超过世界上已投入运行的50MW以上的水轮机水头变幅,其次水轮机运行在高水头区(105~110m)及低水头区(75~80m)时间较长,且需适应初期和后期两种蓄水位运行条件。此外,由于长江汛期水量大、含沙量大、汛后水量少,含沙量少,在调度运行中,水轮机还应适应这一特点。针对上述三峡水轮机的技术特点并提出了对水轮机的若干技术要求。
