Yaremenko M. Rational methods of heat delivery from centralized and autonomous heat sources provided by mutual exploitation

The thesis concerns the rational control of heating system containing centralized heat source, heat mains and local electric heating boilers. The task of rational control was set and solved as a task of nonlinear mathematical programming. Additional usage of local electric heating boilers allows to avoid "overheating" and "underheating" caused by heat-transfer medium transport retard and ensures essential efficiency growth as show the obtained results. Influence of heat and electric power costs on heating system optimum control was investigated. The adequacy of proposed mathematical models and algorithms for the real processes developed in the system is proved by the results of experimental physical simulations.
