This article concentrates on the analysis of building heating systems as controlled objects within the dispatching automated power system of a group of buildings. As a result of experiments, main control, perturbation influence, and the controlled variable - heating system return temperature - are defined. These data form the basis of a developed mathematical model by means of a structural diagram with the use of Laplace transformation. The effect of outer air temperature on the output signal behaviour and the range of the coefficient of a model equation is shown by experiments. To determine coefficients of the transfer function over the main control channel parametric identification of the controlled object was performed and the given model adequacy was shown. This approach forms the basis of mathematical and simulation modelling of distributed power systems of a group of buildings for the purpose of rationalization of energy resources consumption. The obtained results show the possibility to construct distributed groups of buildings with various levels of automation.
