摘　　要：满拉水电站水比机组经常处在低负荷下运行，存在着局部空蚀破坏和运行不稳定两大问题。本文分析了问题存在的根本原因，提出了对在不同水头、不同小负荷运行的各种工况下机组振动应进行监测，对可能出现危及机组安全运行的局部小负荷区应加以回避。[Abstract] The hydraulic turbine unit frequently operates under the low water head, exists the questions of unstable operation and cavitation in Mania hydropower station. The paper analyses the cause of the questions and puts forward that the local low load zone influencing the safe operation of the unit should be evade; the vibration of unit under the various work circumstances of different water heads and different low loads should be monitor.
