Abstract
The relevance of low-power combined heat and power plant (CHP-plant) as alterative heat, electricity and hot water supply source is presented. This paper proposes dynamics mathematical model of exhaust gases utilization area and the heat transfer section into the consumer network CHP-plant with a thermal engine in the form of an internal combustion engine. These sections form thermal energy accumulators, which include a gas-water heat exchanger, a water-and-water heater of the heating network and a water-and-water heater of the hot water supply network. The presented nonlinear mathematical model allows to investigate the dynamic properties of the heat consumers section produced by the cogeneration unit in a wide range of loads. The model takes into account the influence of the change in the outside air temperature in the formation of the water temperature setting of the coolant supplied to the heating consumers network.
