Modified method of mathematical simulation of dynamics of thermothchnical units

摘要

A modified method of lumped parametersis presented. The method makes it possible toconstruct a dynamic model of heat-power objectsthat can be used in the study the control systems.It is shown that equations of dynamics withconstant coefficients characterizing static anddynamic properties of the object can betransformed into modified equations with variablevalues of the coefficients which are determined bythe value and direction of the deviation oftechnklogical parameters. Taking a system ofequations describing the drying installation as anexample we showed that the use of the modifiedmethod provides 5-to 10-fold reduction of thecalculation error and makes it possible toelucidate the special features in behavior of the heat-power object.
