Maintaining variable operating conditions of water barrage, imposed upon the owners of hydroelectric power plants by various acts and administrative decisions, requires proper adjustment of power plant water discharge by variable opening of turbine control components. This changes the generated power and thus shifts the hydro units operating point, which alters the power generation efficiency. In...
Dotrzymanie zmiennych warunków użytkowania stopnia wodnego, narzuconych właścicielom elektrowni wodnych w różnego rodzaju aktach i decyzjach administracyjnych, wymaga odpowiedniego dostosowania przełyku elektrowni poprzez zmianę stopnia otwarcia elementów regulacyjnych turbin. Skutkuje to zmianą generowanej mocy i tym samym przesunięciem punktu pracy hydrozespołów powodującym zmianę sprawności wytwarzania...
The main purpose of the paper is to expose hydropower as a highly valuable, scarcely utilised and increasingly marginalised renewable energy source in Poland. The technical hydropower potential of our country (12-5-14 GWh/annum), provided mainly by our large rivers (Vistula, San, Dunajec), is utilised in less than 16 %. Yet, no large classic hydro power plant has been commissioned for 35 years now,...
