Conception of design of district heating control

Abstract

The District Heating Systems (DHS) are being developed in large cities in accordance with their growth. The DHS are formed by enlarging networks of heat distribution to consumers and at the same time they interconnect the heat sources gradually built. DHS is used in larger cities of some European countries e.g. in Germany, France, Czech Republic, Poland and others. Production technology of heat by means of combined production of power and heat is an important way to increasing of thermal efficiency of closed thermal loop. The complicated process of technological string of heat production, transfer and distribution of heat or possibly of heat consumption requires the system approach when solving the concept of automated control by means of advanced control algorithms. The paper shows the system access to the control of extensive controlled plant.
