Simulation Model Of The Municipal Heat Distribution Systems

This paper deals with the topics of heat consumption in the municipal heat distribution systems and problems linked with modeling and simulation of systems providing heat supply. These systems will be called SHDC (System of Heat Distribution and Consumption). The significant problem in the controlling mechanism of such systems consists in transport delay of transferring heat media. As a result the control mechanism must operate in prediction kind of mode. Essential parameters, or control variables, are temperature of heat carrier and its flow rate. Their time behavior must be predicted for efficient control of the whole heat energy supply. Main focus will be placed on description of the proposed and implemented computer model of the heat distribution system in the selected agglomeration. This model is proposed as a discrete simulation model and implemented in the form of computer application. Model has been tested on real operational data.
