ENERGY SAVING METHOD FOR THE POWER OBJECTS EQUIPMENT SELECTION
Both the general problem and the strategy for choosing the optimal composition of the main equipment of a complex power system consisting of condensation, thermal and hydraulic electric power stations are given in the article. The conventional indicators - a minimum fuel consumption in the thermal power stations and a minimum flow of water in the hydroelectric power stations are the optimization criteria. An approximate solution to this task based on the quasi-linear approximation of the power equipment flow characteristics. The algorithm for a simultaneous optimization of a set of the operating units and their rational loading taking into account a fuel consumption for starts and stops is described too. The efficiency function of the task is determined in the domain of this function that is formed by a system of regime-and-technological constraints.
