The Unbalanced Modes Analyze Of Traction Loads Network

Presently, it has been recognized that unbalanced modes of high-voltage networks occur quit often and adversely affect the electrical consumers and the technical-economic indicators of electric power systems. The adverse effect lies in the fact that under unbalance current, the transmission capacity of three-phase supply systems decreases, the technical-economic indicators of synchronous generators and transformers are reducing, active power and energy losses are increasing, the efficiency of controlling devices use is reduced, and also leads to the deception some type of a relay protection. The study addresses the question of the network mode investigations during the connection of traction substations. For steady-states modes calculation which supply traction load, a mathematical model of a meshed system is simulated with respect to phase variables. The unbalance mode influence to the active power losses and electrical energy is plotted. It has been considered the traction loads balancing with the use of Scott transformer.
