建设一个水电站,总希望它在发电、防洪、灌溉、养殖、航运和生态平衡等几方面的经济效益高些。就发电方面来讲,要提高电站的效益就必须多发电,并且减少设备的运行维护费用。这除了科学的管理和调度外,机组的性能(包括能量特性和汽蚀特性)结构的好坏相当重要,不好的机组给电站今后运行维护带来很大的麻烦。因此在电站设计中,机组选择是很重要的一环。一般来说,小型水电站机组选择设计的任务就是从我国已经生产的机组产品中挑选出适合本电站情况的性能结构较好的机组。在设计中
It is always hoped that the construction of a hydropower station will be more cost-effective in power generation, flood control, irrigation, aquaculture, shipping and ecological balance. In terms of power generation, to increase the efficiency of power plants it is necessary to generate more power and to reduce the equipment operation and maintenance costs. In addition to scientific management and dispatch, the performance of the unit (including the energy characteristics and cavitation characteristics) structure is very important, bad unit to the power station in the future operation and maintenance bring great trouble. Therefore, in power plant design, unit selection is a very important part. In general, the task of small hydropower unit selection design is to select from the unit products already produced in our country, a unit with good performance and structure suitable for the power station. In design
