摘要：

In this paper, a mathematical model of connection method between ring-shaped heat-supply systems with multi-heat sources was established based on the requirement of limited-heating in accident conditions. The limited-heating coefficient, pressure bearing capacity of pipeline, heating capacity of heat source, operating parameters of circulating pumps were used as boundary conditions, and the minimum consumption of transmission energy of heat sources was considered to be the objective function. A case was analysed to illustrate the solving process and the calculation method of the model. Using the mathematical model proposed in this paper, the feasibility of the connection method between the heat-supply systems on accident conditions can be analyzed under steady state and system completely be controlled condition. The optimal connecting case was obtained. The results have important significance for urban planning and the reconstruction design of heat-supply system. (C) 2016 The Authors.
