Abstract:
The paper presents the outcomes of the research aimed at developing digital models for calculating the operating conditions of railway power supply systems (RPSS) incorporating wind turbines. The implementation of the models relies on the methods of phase coordinates, which enable a systems, universal, and comprehensive approach. The systems dimension is achieved by considering all the significant properties of a complex RPSS and a supply network. The versatility is ensured by modeling traction networks, power lines, and transformers of various designs. The comprehensiveness lies in the possibility of calculating the normal, emergency, and special operating conditions in the RPSS. The study highlights a variety of applications of the wind turbines: to power the facilities located in regions with unstable energy supply; to enhance the reliability of power supply to the consumer whose disconnection could lead to serious consequences; to supply energy to relatively low-power facilities.
The creation of the calculation model for the RPSS requires the implementation of an algorithm for the interaction of models of individual components and includes the following stages: modeling the rolling stock traffic schedule; developing instantaneous diagrams corresponding to specific time instants and calculating their operating parameters; determining integrated modeling indices. The results obtained using the Fazonord software indicate that the use of wind turbines can bring about the following benefits: cutting down energy supply costs; reducing unbalance on the busbars of traction substations, stabilizing voltage levels on the current collectors of electric locomotives.
