Strategy evolution of control of extensive district heating systems

The paper deals with Strategy Evolution of Control of Extensive District Heating Systems. There are the experiences from the building up of the advance control algorithms of the of the technological string: combined production of heat and power - transport and distribution of heat - heat consumption. 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, Denmark, Finland, Sweden, Netherlands, Czech Republic, Poland and others. Production technology of heat by means of combined production of power and heat (CHP) is an important way to increasing of thermal efficiency of closed thermal loop. The paper shows the system access to the control of extensive DHS - controlled plant. It concerns automatic control of technological string "production, transport + distribution, consumption" of extensive district heating and that is the contribution of this paper. Control by means of advanced control algorithms is a tool (up to now neglect) for decreasing cost of energy and increasing the level of environment protectionhese instructions give you basic guidelines for preparing camera-ready papers for conference proceedings.
