| Abstract: | The theory and realizing plan of on_line monitoring system of cavitation in hydropower units are introduced. On this basis, the design pattern is put forward. The field test of number 4 unit in Bapanxia hydropower plant is completed. The Variating characteristic of cavitation strength with load is obtained. The condition maintenance in hydropower plant is useful exploring. |
