琅琊山水电站地下发电机层气流组织后续模型试验与研究

Continued Model Experiment and Study on Airflow Distribution of the LangYa Mountain Hydropower Station's Underground Dynamo Floor

本文通过对琅琊山抽水蓄能电站地下主厂房发电机层采用不同送风量、不同上下游排风比例的主厂房拱顶送风的热态相似模型试验,对比各种工况下发电机层的空气分布特性,提出适合琅琊山电站发电机层的最优化拱顶送风方案。

According to thermal state similitude model experiment of the LangYa mountain hydropower station when we adopt different velocity of air ventilation and exclude air proportion of upriver and downriver, this paper contrast the air distribution of the dynamo floor on each method, and educe the best projects of arch crest supply air that adapt to LangYa mountain hydropower station＇s dynamo floor.
