Application of distributed variable frequency technology based on fixed pressure control point

Based on the establishment of a smart heat network platform, reforms a heat supply system by the distributed variable frequency technology. Chooses the node 22 as the fixed pressure point, and controls its pressure head at 15 m, solving the problems of high pressure and serious hydraulic imbalance in the original heating network. The operating data during the heating season of 2015-2016 shows that the actual flow rate and heat consumption are consistent with the design values, achieving the expected effect.
