A dynamic mathematical model of a district heating system using the first law of thermodynamics was developed and applied to the simulations of dynamic control systems.The simulation results have shown that,with the hydraulic balance of the secondary pipe network,the best energysaving benefit of the substation(the heat saving rate was 18.49％,the primary/secondary electrical saving rate was 62.41％and 43.47％respectively)could be obtained by obtaining the supply water temperature set-points from the heat source through the dynamic model simulation and utilizing the indoor air temperature to compensate the water temperature in the secondary side.
