17th International Symposium on IceSaint Petersburg, Russia, 21-25 June 2004International Association of Hydraulic Engineering and ResearchHYDROPLUS FUSEGATE SYSTEM:ANALYSIS OF WINTER MONITORING DATAAT THE KHOROBROVSKAYA HPPV.B. Rodionov 1 , G.F. Onipchenko 1 , Julien Rayssiguier 2ABSTRACT“Hydroplus” fusegates (fuse link) is innovative effective technology to reduce waterlevel fluctuations at upstream during crest discharge pass and to increase operate reliability,because neither hoisting equipment, no power supply are needed for their service.Also fusegate technology basing on “fuse link” principle, ensures a pass of rarefloods.Throughout the world fusegate technology becomes more popular being adopted both inhydrounits under construction and under renewal. However, up to now fusegates havebeen adopted mostly in the countries with warm or tropical climate.First in Russia these fusegates have been installed on the Dam of Khorobrovskayamidget power plant for testing service. Hydraulic Research Centre (HRC) of JSC NIIESperformed spillway monitoring during two winters 2001-2002 and 2002-2003. Resultingmaterial describe fusegate service properties in winter conditions.Analysis of obtained material and recommendations to expand fusegates applicationzone for the climatic conditions of Russia are given in the Paper.The conditions of ice pass during floods and winter discharge through the crest of fusegatesare also under consideration. Some other constructions of fusegates type ensuringice pass during overflow of flood discharge through the crest of fusegates, worked outin HRC of JSC NIIES, are proposed.Russian Utility RAO has built a 160-kW experimental hydropower plant on the Nerl-Volzhskaya River for field testing of new technologies. One such technology recentlytested is the Hydroplus Fusegate System. Testing results show that the Fusegates can bea viable alternative to conventional gates, which have presented numerous problems inthe past, for use on small HPP spillways, even in the harsh Russian winters.1 Scientific Research Institute of Energy Structures (NIIES – JSC RAO “UES of Russia”) P.O.
