Simulation methods for the heat distribution systems

Abstract

This study deals with the issues of heat consumption in the urban agglomeration and problems linked with modeling and simulation of systems providing heat supply. In this article we will call such system SHDC (System of Heat Distribution and Consumption). The key problem in the controlling mechanism of such systems consists in transport delay of transferring heat media. Therefore the control mechanism must operate in prediction kind of mode. The two control 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. The simulation is one of the methods, which can be effectively used for the analysis of large and complex dynamic systems properties such as the municipal heating networks --distribution and heat consumption system. The model is implemented in the form of computer applications and tested on real operational data.
