FIELD: power engineering, in particular, centralized heat supplying systems. ^ SUBSTANCE: method includes heating grid water in grid heaters of heating energy plants, feeding hot water via feeding water main to heating and hot water providing systems, cooling of reversed grid water by heat pump plants, positioned at heat stations, returning of cooled water via reverse water main to grid heaters, while heat pump plant is made cascading with finalizing water loop, in upper branch of cascade, positioned at heat station, secondary heating of water of heating system is performed due to additional cooling of reverse water of heating system, by water loop of grid water and heating system upper and lower cascades of thermal pump plant is closed, and in lower branch of cascade, positioned at thermal power station, heating of cooled reversed grid water is performed due to heat of condensation of steam processed in turbine. ^ EFFECT: higher efficiency of heat power station and heat supplying grid, increased heat productiveness of heat supplying system. ^ 1 cl, 1 ex, 1 dwg |
