FIELD: power industry.
SUBSTANCE: optimum control system of energy-efficient cogenerating plants includes a miniature thermal power plant consisting of a gas turbine engine, an electric generator and its control modules, a waste heat exchanger, intermediate heat exchangers, a peak boiler, a heat pump condenser, hot water supply heat exchangers and a heat pump of low-potential heat. A new feature is that the system is additionally provided with a control module of heat energy flows, a cellular communication module of the miniature TPP, a cellular communication module of consumers, N temperature sensors of consumer rooms, N sensors of voltage value at consumers, setting devices of minimum and maximum voltage values of at consumers, N comparison units of minimum temperature and N comparison units of maximum temperature of consumer rooms, N comparison units of minimum voltage and N comparison units of maximum voltage at consumers; at that, N information outputs as to temperature of consumer rooms of cellular communication module of the miniature TPP are connected to the control module of heat energy flows and the first inputs of N comparison units of minimum temperature and N comparison units of maximum temperature of consumer rooms, the second inputs of which are connected to setting devices of minimum and maximum temperatures respectively, N information outputs of voltage value at consumers of the cellular communication module of the miniature TPP are connected to the control module of heat energy flows and the first inputs of N comparison units of minimum and maximum voltage respectively, outputs of N comparison units of minimum temperature and N comparison units of maximum temperature of consumer rooms, N comparison units of minimum voltage and N comparison units of maximum voltage at consumers are connected to the control module of heat energy flows, temperature sensors of consumer rooms and voltage value at consumers are connected through inputs of cellular communication modules of consumers.
EFFECT: improving control efficiency of cogenerating plants by means of continuous control of distribution of heat flows.
