Abstract

When the pipeline bursts and leaks, the make-up pumps will turn on to supple the network with water. Due to the outdoor heating network is a closed cycle, and equipped with the make-up water pumps, the hot water will leak continually under a constant pressure at the leak point, which causes thermal waste. Therefore, locating the leaky section in heating network is more and more important. In this paper, the mathematical model of a branching pipe system was established by using the graph theory and genetic algorithm. Programming calculated the flow and pressure of all pipe sections and heat exchange stations when the network is normal operation and leaky operation, respectively. And through analysis of the change law of pressure and flow, the rules of hydraulic regime changes can be obtained. Moreover, the leaky section will be found out efficiently.
