Abstract
Cogeneration is popular among private and commercial consumers. Cogeneration units can significantly reduce capital costs for electricity and heating. The article is focused on the issue of control system synthesis of combined heat and power plant thermal energy generation circuit, which includes hot water supply and heating system. The model of the control object is described by a system of nonlinear equations. The developed control system consists of two PI regulators that change the flow of flue gases entering the heat utilizer and distribute the coolant flow between the heating heater and the hot water heater. The research of automatic control system under the influence of various perturbations like changes in the temperature of flue gases, fluctuations in the flow of water consumed in the hot water supply system and the temperature of water entering the hot water supply system has been carried out. The advantage of the developed control system is the invariance to perturbations caused by fluctuations in the air temperature, which affects the task change of the temperature regulator of the coolant in the heating system
