三峡电厂左岸ALSTOM机组低水头性能分析

Function analysis of ALSTOM units on the left bank of Three Gorge hydropower station operated under low head

通过对三峡电厂左岸ALSTOM生产的6台机组的稳定性试验,并且在上游水位由135m上升至139m过程中,对6#机进行了7个水头段的相对效率试验及稳定性试验,全面了解了机组在低水头下运行时的能量特性和稳定性特性,为电厂经济、稳定运行提供可靠的依据。

Through the stability experiment for the six ALSTOM units on the left bank of Three Gorge hydropower station and the relative efficiency and stability experiments for the No. 6 unit with 7 heads （corresponding to reservoir level rising to 139m） the energy and stability characteristics of the ALSTOM units operated under low head is known. It provides the dependable basis for the economy and steady operation of the station.
