Research of questions of control automation of the city district heating system with the object structure optimization

Максим Віталійович Максимов, Сергій Володимирович Бабич

Abstract


The paper proposes a new solution to the problem which lies in improving the methods and models for automatic control of the city district heating system to increase economic efficiency by target change of the control object structure.

The analysis of the control object, methods and models used in the heating control of the city and districts was performed. Simulation models of the control object, which operate in the presence of alternative energy flows, differing in cost were developed. Optimization criteria and objective function of the city district heating were synthesized and justified. The heating optimization problem of districts by switching from the structural control object optimization to the price structure control of energy flows, proposed to the consumer was solved. Computer-integrated control systems and control of the proposed objects was practically implemented in order to assess their effectiveness.
