Abstract: In the power generation process of Shanxi hydropower station, over frequency action was found with the air valve of hydro turbine. It was proposed to improve its operation condition by rising the tail water level by 1.2 m. The paper analyzes the adverse influence of tail water level rise to the operation of hydropower station. As well, by analysis of the forming of negative pressure, the countermeasures are put forward, for reference.
Key words: Shanxi hydropower station, air valve, fault removal
