The paper is concerned with the functional scheme and the basic equipment of a thermal station. Parameters requiring control in the continuous process of the heat transfer medium production and its delivery to the consumer are listed. The authors show the technological relationship between water heating conditions and the thermal station controlled electric drives providing the predetermined process conditions. Functional relations determining the balance of water flow and water pressure of the thermal station and the consumer as well as the relation of water flow and temperature of the hot water boiler are given. The functional scheme of control system for the thermal station output parameters and the block scheme of the local control systems of the heat and water balance are shown. The principles of process parameters control are justified.
