小型无压引水式电站枢纽布置探讨

小型无压引水式电站主要建筑物包括首部枢纽、引水明渠(或无压隧洞)、压力前池、电站进水口、引水钢管、发电厂房等。枢纽布置时可结合前期水文规划确定的水电站规模,并考虑地形地质条件及各建筑物间的关系,通过简化计算,先初步拟定建筑物位置、型式及尺寸,再依据规范进一步核算各建筑物是否满足要求,并进行调整后最终确定枢纽布置。

The main buildings of small free flow diversion type power stations include the first hub, open diversion channel (or free flow tunnel), pressure front pool, power station intake, water diversion steel pipe, power plant and so on. The layout of the hub can be combined with the scale of the hydropower station determined by the previous hydrological planning, and taking into account the topographical and geological conditions and the relationship between the buildings. Through simplified calculation, the location, type and size of the building can be preliminarily drawn up. Then according to the code, this paper further calculates whether the buildings meet the requirements and, after adjustment, determines the final layout of the hub.
