Considering different land parcel structures and various operation conditions existing in energy supply network for Client-Oriented combined cooling, heating and power System (CCHP), it leads to a long cycle and high cost for debugging. And the debugging of energy supply network is also affected by the season, resulting in poor flexibility. Aiming at this problem, the client-oriented energy supply network model is proposed in this paper to simulate operation conditions of real energy system and to study the working performance of controlled energy network. The models of pipelines, heat exchangers and valves are therefore created. The proposed system model is set up in MATLAB through establishing the mathematical models of the above mentioned objects and analyzing the structure of system. Based on the model, the control strategy of valves are investigated to regulate the flow of transmission medium, so as to control the secondary-side water supply temperature, the primary-side return water temperature and differential pressure. The simulation results show the feasibility and effectiveness of the proposed model, and the proposed model has a certain guiding significance for the debugging operation and control regulation of the energy supply system.
