Study on calculation method for availability of centralized heat-supply system

Establishing the heat-supply network availability mathematical model based on the smallest cutset under actual conditions by unified method of the probability and the fault conditions hydraulic simulation.First enumerates component fault of pipe network, simulates the flow of the heat-supply network and heat user under this operating conditions by the solution of matrix equation of pipe network, and compares with the permission minimum flow, thus discovers the smallest cutset of heat user and pipe network system under actual conditions, finally answers availability of repairable heat-supply network and heat user by the smallest cutset means.
