Study for the Scheme to Shut Valves and Topology Recomposition under Fault Conditions to Heat-Supply Network

A sort of shutting valves scheme was brought forward when heat-supply network failed and a kind of network recomposition system of topology was suggested here. Based on the normal condition topology structure, this system could automatically recompose fault conditions topology structure according to the way of shutting valves scheme. Validity and effectiveness of this method was verified by a real case and this method provide a feasible way to hydraulic analysis of ring-shaped and non symmetrical heat-supply network under fault conditions.
