Research Of Heat-Exchanging Equipment's Dynamic Character And Energy Regulating And Controlling System

The operation and regulation is a weak link of heating engineering.Essential reason is lie in the choice of controlled parameter that is very important in heating system,because controlled parameter relates to quality of heat net operation and regulation. The chosen controlled parameter must be single function of extraventricular temperature because extraventricular temperature affect immediately radiator's emitting heat,heat net supplying heat and user's heat load.but the sometime chosen controlled parameters all are't extraventricular temperature's single function. The average temperature of supply water and backwater only is single function of extraventriculartemperature.so only it can reflect radiator's emitting heat,heat net supplying heat and user's heat load.Due to the features of board heat-exchange euipment's simple structure,easy unpicked and washed and high heat-transfer coeffcient,it is used extensively in heating system. Heat-exchange euipment is a very important link in heating system which is controlled object by way of heat power station's energy control system.the dynamic characteristic of heat-exchange equipment is the important basis analyzing, designing and improving on it and more effective regulation to heat power system.The thesis analyse the dynamic characteristic of heat-exchange equipment from the regulation channels and interference channels by the way of system simulation,and confirm the law of dynamic response of the second average temperaure when the first flow(or temperature) or the second flow change,and finish the design of heat power station's energy regulation system hereby it.At last ,it simulate heat-exchang equipment and heat power station's energy regulation system by using MATLAB/SIMULINK.
