Research on Anti-runaway Protection Measures for Hydro-turbine Generator Units of Diversion Type of Changbo Hydropower Project
As to characteristics of the diversion type of Changbo Hydropower Project,such as the water diver-sion distance is long,setting up upstream surge chamber,and diameter of water pipe in front of the scroll case is relatively large,three kinds of anti-runaway protection measures for hydroelectric generating units are listed for analysis and comparison.After comprehensive comparison and analysis,this paper recommends the surge chamber rapid-drop gate as the anti-runaway protection measure for hydroelectric generating units,and de-scribes the the scheme in detail.It provides a reference for the selection of anti-runaway protection measures for hydro-turbine generator units under similar conditions.
