Application of distributed heating transmission and distribution systems in secondary network reconstruction

 Due to its power saving and flexible adjustment characteristics, the distributed heating  transmission and distribution system is more mature in the primary network, and less popular in the secondary network. Taking a heating project in a severe cold zone as an example, by comparing three types of heating schemes, concludes that the use of distributed heating transmission and distribution system to transform the secondary network of the heat exchange station has a better heating effect, and the power saving reaches 17.7%, which provides a new idea for solving the balance problem of secondary network.
