陶岔渠首水利枢纽水轮发电机组选型设计研究

Design Study on Type Selection of Turbine-Generator Unit,Taochan Canal Head Project

陶岔枢纽是南水北调中线输水总干渠的渠首工程,通过分析该电站与一般径流式水电站特征与机组运行特性的不同,详细论证了该电站额定水头的确定方法及其影响因素,同时为满足调水流量时减少渠首闸门启闭次数,以避免增加运行维护管理的复杂性和难度,设置了机组最大出力,进而确定了陶岔渠首枢纽水轮发电机组性能参数及型号。研究结果为同水头段水轮发电机组选型以及同类型电站的安全高效运行提供一定的参考。

Taocha Project is the head one of central canal of South-to-North Water Diversion Project. Through analysis on difference of characteristics and operation features between Taocha Canal Head Project and common run-of-river hydropower project, determining method for the rated head of the Project and its relevant affecting factors are demonstrated in detail. Furthermore, the maximum unit out- put is designed in order to satisfy reduction of the head gate operating times while water discharge is adjusted so as to avoid increment of complication and difficulty of operation, maintenance and management, performance parameters and model of the turbine-generator units for Taocha Canal Head Project are finalized. The study results provide type selection of turbine-generator unit at same head range and safe ＆ high-efficiency operation of the similar hydropower stations with reference.
