农村小水电水能降损研究综述

A Review of Water Energy Loss Reduction in the Rural Small-hydropower Station

农村小水电作为可再生的清洁能源,大力发展农村小水电兼具经济效益和生态效益。我国可开发小水电资源丰富,小水电建设历史悠久,但是当前我国的农村小水电存在着诸多问题,如金属结构设备锈蚀严重、压力管道水头损失过大、引水系统的渗漏损失过大等,农村小水电降损研究迫在眉睫。在概述农村小水电结构形式的基础上,总结了降损的研究方法,并从水头损失和水量损失两个方面综述了农村小水电降损研究进展,为今后农村小水电降损研究提供了依据。

Rural small-hydropower is a kind of clean and renewable energy .To develop rural small-hydropower has benefits economi-cally and ecologically .Our country has abundant small hydropower resources to develop .Small hydropower station construction has a long history ,but currently there are many problems in rural small-hydropower ,such as serious corrosion of metal structures and equipment ,head loss of pressure piping is too large ,leakage of water diversion system is too large ,etc .Research on rural small-hy-dropower loss reduction is imminent .In this paper ,on the basis of an overview of the structure of small hydropower in rural areas , it sums up research methods for the loss reduction ,and summarizes the research progress in reducing loss of small rural hydropower from head loss and water loss .it provide a basis for rural small-hydropower reducing losses in our future research .
