本文所指的中、小型水电设备是指水轮机、发电机、阀门等设备,其价格是指制造厂家交付用户的出厂价。通常,在进行水电站设计时,由于缺少机组设备价格资料,很难估算电站的投资。当向制造厂家询价时,有些厂家因缺乏足够的预算资料,提供的价格往往偏高。为了保证设计阶段所作的工程预算尽可能地准确,我们根据1986年市场上通行的和国家规定的水电设备价格进行统计分析,得出一套计算公式,采用这套公式可以较准确地估算出中、小型水电设备的价格,它将给设计工作带来一定的方便。进行设备价格分析的具体方法是:以设
Medium and small hydropower equipment referred to in this paper refers to equipment such as turbines, generators and valves. The price refers to the ex-factory price delivered by the manufacturer. In general, it is difficult to estimate the plant’s investment in the design of hydropower plants due to the lack of price information on plant equipment. When inquiring the manufacturer, some manufacturers tend to offer high prices due to lack of adequate budgetary information. In order to ensure that the engineering budget made in the design phase is as accurate as possible, based on the statistical analysis of the prevailing prices of hydropower equipment in the market in 1986 and the state regulations, a set of calculation formulas are derived, which can be used to accurately estimate the medium , The price of small hydropower equipment, it will bring some convenience to the design work. The specific method of equipment price analysis is: to set
