摘　　要：对于最大水头Hmax≤10.0m的低水头径流式水电站,宜选用三叶片转轮灯泡机组。其参数选择与原四叶片、五叶片转轮有一定的差异,单位流量Q11可取3.5m3/s左右;对额定点效率不宜要求过高,宜取90%左右;额定转速选择应以高于额定水头工况为主考虑,即优先考虑非汛期运行效率。For a low head runoff hydropower project with Hmax≤10.0 m, it is preferable to select three-vane bulb units. The parameter selection for a three-vane bulb unit is different from that for the original four or five-vane runner. The specific discharge Qn may be taken as about 3.5 m^3/s and the efficiency of rated point is unnecessary to be too high, it should be taken as about 90%. The rated speed shall be selected with consideration of operation at a head higher than the rated head, i.e. , the operation efficiency in non-flood period takes precedence.
