丹江口大坝加高工程电厂机组设备改造项目经验总结

Rehabilitation experience of machinery and equipment for power plant of Danjiangkou Dam

南水北调中线水源丹江口大坝加高工程自2005年开工建设,按照初步设计规划,大坝加高后由于正常蓄水位发生变化,电厂机组运行的主要设计参数也发生了变化。对电厂机组改造方案和调试运行结果进行分析,并针对改造实施过程中的招标文件编审、设备制造保障、设备安装调试以及建设中各种问题的协调等经验进行总结,论证了改造方案的合理性,为类似工程电厂机组设备改造提供经验和借鉴。

Abstract： Danjiangkou Dam Heightening of the Middle Route of South-to-North Water Diversion Project started construction in 2005. According to preliminary design, key parameters of the power generation units will be al- tered due to the change of normal storage level after the dam heightening. A summary of experiences is made based on the evaluation of rehabilitation of power generation unit and results of commissioning and testing, in- eluding preparation of bidding document, equipment manufacturing, installation and trial operation. It is found that the rehabilitation is feasible and achieved satisfactory result. The experiences and lessons learned from the Danjiangkou can be of good reference for other similar projects.
