摘　　要：通过对大型混流式水电机组分别采用导叶大加速开环启动、导叶小加速开环启动、机组加速度控制闭环启动和开环+闭环启动等4种开机方式时,机组运行稳定性试验研究,全面分析比较了机组在不同开机方式时的机组稳定性。结果表明,综合考虑开机时长和机组稳定性等因素,机组的最佳开机方式为导叶小加速开环启动。该研究成果为混流式水轮机开机方式的选取和优化提供了依据。This study conducts operation stability tests on a large Francis hydropower unit in four startup modes–large acceleration open loop start of guide vanes,small acceleration open loop start of guide vanes,closed loop start of unit acceleration control,and open-plus-closed-loop start.We analyze and compare the stability of unit operation in these modes comprehensively.The results show that considering start-up time and unit stability,the first mode above is best.This study lays a basis for selecting and optimizing the start-up mode of Francis turbines.
