Abstract
The article considers questions of optimization of industrial power-supply systems conditions with the own sources of electrical power using original software "KATRAN 7.0", which makes it possible to receive optimal values of generators power. The algorithm is based on the method of dynamical programming and takes into account active power losses in distribution electrical network, heterogeneity of used fuel, non-modular structure of the thermal station. The technique of optimization the power–supply system conditions of large industrial plants was given. Calculation of cost-effective conditions was realized in the power-supply system of a large steel plant. The results of the research work are intended for the dispatcher services of industrial enterprises.
