Abstract: The old unit of Etan Hydropower Station was reformed for capacity expansion using the original power house. The normal level in upper reaches of reformed unit was raised, and the pressure upon the flow components was increased. The force analysis of upper cover of reformed unit was accomplished, and it is determined by which that whether require to replace a new upper cover for the reformed unit.

Key words: reformation for capacity expansion of hydropower station, parameters of unit, upper cover, force analysis, calculation
