Studying of Possible Operating Modes in Graphics of Electric Loads of Combined Heat and Power Plants Taking into Account Heat-Sink Properties of Thermal Networks

Conditional splitting the heat highway into sites and assessment of nature of temperature change of a pipe and also direct and return network water on each site allowed to specify the average temperature of a pipeline wall used in the differential equations and a technique, developed earlier, allowing to estimate the influence of heat-sink properties of thermal networks on delay of the temperature changes at the consumer. Calculations for various lengths of pipelines at a constant consumption of direct network water, constant temperature of external air, constant internal pipeline diameter and at various temperature changes of direct network water on a source were carried out. Calculations showed that time of non-stationary process increases for the accepted conditions at increase of the direct pipeline length of thermal network.
