Interval data analysis in the task of estimation of possibilities of the small hydroelectric power station “Topol'ky” capacity increasing

The task of multiple-set estimation of factors values, which within certain boundaries are ensuring the set characteristics of electric power generation, is considered. For the task solving the interval data analysis methods are applied. The used multiple estimations of values of water expenditure in the turbine, the water head and the reactive capacity determine the preconditions which within certain boundaries are ensuring the set characteristics of electric power generating.
