Abstract
The issues of using adjustable power sources to provide preventive anti-icing heating of contact network wires are considered. It is indicated the problems of the system of preventive heating of the wires of the section contact network that arise when trains move along it, associated with the cooling of the suspension due to changes in currents in the traction network. It is presented an algorithm for controlling sources of preventive heating which ensures that the temperature of the wires is maintained to prevent their icing without introducing additional restrictions on the train movement. The algorithm takes into account the temperature limits which the heating of the wires is maintained, as well as transient processes that occur during switching, and the service life of the equipment.
