APPLICATION FOR A CASCADE OF HYDROPOWER PLANTS Cristian PurecePhD, Scientific Secretary, INCDIE ICPE-CA Bucharest Subunit ICEMENERGDaniela Adriana SimaPhD student, UN\u015eTPB\/INCDIE ICPE-CA Bucure\u015fti AbstractIn this paper, the authors briefly present the methods for determining in situ the efficiency \/ performance of a hydraulic turbine as well as the purpose, the necessity of applying the methods of in situ determination of the efficiency of the hydraulic turbines from a hydropower plant. These efficiency tests are an essential practice to ensure that the performance of the hydraulic turbine and the hydropower plant have not degraded to unacceptable levels. Also in the paper are presented the results of the efficiency tests carried out at a cascade of three hydropower plants, form Romania, from the arrangement of the R\u00e2ul Mare downstream. Keywords: hydropower plants, discharge determination, turbine efficiency, in situ tests, hydro-unit.
