摘要
云南华电绿水河二级电站在建设期受到当时技术水平的限制,1969年设备投产后问题较多,电站进行过了多次技术改造。本次增容改造主要目的是在不改变现有流道的情况下,对4号水轮机进行增容改造,发电机出力由15MW增容到18MW,保证额定效率不低于91%,汽蚀满足电站要求和高稳定性。
Yunnan Huadian Lushuihe Level II power station is limited by contemporary technical level during the construction period. The problems were excessive after the equipment was put into operation in 1969. The power station underwent many technological transformations. The capacity increase transformation mainly aims at increasing capacity and transforming No. 4 turbine under the condition of not changing existing flow path. The output of the power generator is increased from 15MW to lgMW. It is ensured that the rated efficiency is not less than 91%. The cavitation meets the power station requirements and high stability.
