Distributed simulation modeling of district heat supply system in VisSim
A.A. Basalaev, South Ural State University, Chelyabinsk, Russian Federation, email@example.com
This paper describes an approach to constructing distributed simulation model of district heat supply system using a computer in VisSim simulation environment. The approach is based on division a model into interconnected subsystems, simulation of which can be processed by area network nodes simultaneously. Ways to synchronize model subsystems obtained by the division of initial system are supposed. Advantages and disadvantages of these ways are described. The presented results of simulation of district heat supply systems with different number of consumers confirm that calculation speed of a model with large number of basic computational units and nonlinear equations increases in case of the division this model into interconnected subsystems.
