FIELD: power engineering.
SUBSTANCE: heat electric power supply system consists of heat energy use sub-system, straight and return main pipelines of heat network, circulation circuit of heat carrier of centralised heat supply at least with one heating unit of the building, and electric power supply sub-system. At that electric power supply sub-system consists of power plant; power lines; at least one liquid transformer consisting of at least one winding; tank with transformer liquid; circulation pump; and separating heat exchanger the secondary circuit whereof is equipped with circulation pump. When the above circulation pump is in operation, heat carrier of secondary circuit of separating heat exchanger is supplied to one heating unit of the building, which is connected to secondary circuit of separating heat exchanger. Version of heat electric power supply system is described as well.
EFFECT: improving efficiency, ecological properties and reliability of the system, fuel calorific capacity fully used by centralised heat supply source, and effectiveness of heat removal from transformers, reducing temperature loads on electrical part of the system during intense ambient temperature decrease, cost of operation and overall dimensions of electrical transformers.
