Aiming at the problem that building new power system requires conventional hydroelectric units to have a wider load operating range and faster regulation ability
taking a large francis turbine of a hydroelectric power plant as the research object
the research on the wide-load flexible regulation reformation is conducted
the operation characteristics of the old hydro turbine in hydroelectric power plant in the past ten years and the existing problems are counted
the reasons why the old unit does not adapt to the new power system and the difficulties in the reformation are analyzed
and the technical scheme of reformation is put forward and verified by model test. The results show that the proposed wide-load reformation scheme is feasible and can provide a reference for the reformation of other old hydroelectric units of the same type.
