摘　　要：丰满电站水轮机额定出力为204MW,水头变幅H_(max)/H_(min)=1.61范围超过了混流式水轮机常规的适应范围,机组运行范围比常规电站宽广,机组需要频繁在小负荷进行调峰、调频运行,并且,重建后出现了8台机组在不同2个电网中进行调峰调频工作。因此对机组的稳定性要求更高,尤其是部分负荷的稳定性。本文结合丰满电站特定的运行条件,提出了模型开发过程中改善丰满水轮机稳定性的措施,通过试验验证,满足丰满电站的运行特点。The fengman power station turbine rated output is 204MW, the variation range of head Hmax/Hmin=1.61 is more than that of conventional Francis turbine. The operating range of the unit is wider than the conventional power station. The unit needs frequent peak-frequency modulation in small loads, and the reconstruction of eight units need work in two different power grids for peak-frequency modulation, therefore, the stability of the unit is higher, especially the partial load stability. The article combined with the operational characteristics of fengman power station, puts forward the measures to improve the stability of the turbine during the model development, through experimental verification, meeting the operational characteristics of Fengman power plant.
