地下水电站通风方案设计与分析

Design and Study of a Ventilation System for Underground Hydropower Station

地下水电站通风设计关系到水电站运行状态和寿命,有效、安全、合理、节能和经济的通风设计是一个成功水电站所必需的。针对新疆某地下水电站工程提出4种通风方案,并对每个方案的气流组织进行介绍,按照满足该项目的温度湿度参数要求,计算了相应的系统设计风量。然后从各方案的可行性、初投资、运行费用、费用年值对4种方案进行了分析,最终根据方案比选结果确定推荐方案。

Design of an underground hydropower station determines its lifetime and stability.To con-struct a successful hydropower station, the effective, reliable, reasonable and economical ventilation system is essential. Four ventilation schemes are introduced for one hydropower station in Xinjiang Uygur Au-tonomous Region, and air distribution and ventilation volume of each scheme are shown, that can keep hy-dropower station in reasonable temperature and humidity. At last, the best design will be chosen from the perspective of feasibility, initial investment, operating cost and annual cost.
