摘要
Abstract
The continuous vigorous development of hydropower under the new power system has brought opportunities for hydropower development in small and medium-sized river basins.With low hydraulic loss of flow passage,large discharge capacity of turbines,and high operational efficiency and performance,bulb tubular hydropower plants have broad application prospects.Based on several engineering design cases of bulb tubular hydropower plants at home and abroad,this paper discusses several key issues such as rated head,number of runner blades,main turbine parameters,and high-head ratio,and summarizes relevant design experiences;for instance,the number of runner blades is generally set at 3-5;Hmax/Hr shall not exceed 1.80;Hmax/Hmin is commonly between 3.0-4.0;a well-designed power plant equipped with two types of units can ensure stable operation and improve economic benefits,etc.The research results can provide references for designers,college faculty and students,as well as manufacturers,installation teams,operation & maintenance departments of bulb tubular units.关键词
