Energy saving effect in heating systems of industrial buildings without 24-hour supervision is reached using the automatic heat management systems. Our paper offers a specific scheme for the automation of a local heat supply station (LHS) with an autonomous heat accumulator and a dual-circuit coolant circuit. The proposed technical solutions can only be effective if the compliance of the thermal resistance of the external enclosing structures of the building to the established requirements is observed.

Writing the differential equations of an asynchronous electric motor on the basis of a generalized electric machine in different coordinate axes can not only reduce the number of model equations, but also introduce various factors in the mathematical description that increase the modeling accuracy. It is proposed to write the equations of the mathematical model of an induction motor taking into account the saturation of the magnetic circuit and solve them using the Matlab application package. The proposed approach improves the accuracy of calculating the mechanical characteristics of an asynchronous electric drive.
