Abstract
Modern requirements for traction DC power supply in the organization of high-speed movement are reduced to the need to provide a normalized voltage level of 2900 V on the pantograph of electric locomotives. The existing power supply system does not allow to provide the necessary mode of voltage at change of load and the necessary specific energy consumption, despite the considerable aggregate power of traction substations. The purpose of the work is to develop a hybrid traction system with the use of alternative generators of electricity. The article presents the algorithm of interaction of different types of generation when the traction load is changed. The developed hybrid power supply system for electric rolling stock allows to provide the necessary voltage level on electric locomotive pantograph and to reduce the range of its changes, which will allow to fulfill the necessary conditions for ensuring high- speed movement without changing the voltage in the traction line.
