Project description:The Váh cascade has been built to present state for more than 60 years. Single hydropower plants and whole hydropower plants were designed and constructed with different hydraulic parameters, allowing operation of hydropower plants from run-of-river regimes through semi-peak-load regulation up to peak-load regulation. Presently are during the common operation the hydropower plants of the Váh cascade used for generating of peak-load power and for covering of unplanned load demands in the electrical power system. Lately, providing supportive services for EPS (power backup, covering of steep peaks of daily load demand, etc.) is being put forward. This situation changes during diversion of increased discharges respectively of flood discharges. During the last years e.g. summer 1997, spring 2000, summer 2002, have the hydropower plants of the Váh cascade remarkably participated on the flood diversion by means of their hydraulic characteristics and adjusting their operational regime. By such operation, when there are increased discharges in the river Váh, is changed the operational regime of the hydropower plants of the Váh cascade. Hence the tasks of verifying possibilities of flood diversion mostly through canal hydropower plants, assessment of their cooperation during flood elimination and defining changes and risks by such operational regime, which arise by their use for actual needs of electrical power system of Slovak Republic, are being put forward. The solution of presented grant-project would establish on results of two previously solved grant-projects : ?Influence of silting pools on regulating facilities hydropower plants with considering water transport? (solved in 2000-2002) and ?Verification of marginal possibilities of regulation operation of hydropower plants with respect to reservoir silting and parameters of navigation? (solved in 2003-2005). Flood situations, which cause change of operational regime of regulation hydropower plants of the Váh cascade.
