RAISING OF POWER FACTOR OF ELECTRIC LOCOMOTIVE AT REGENERATIVE BRAKING REGIME
Abstract
Electrical power scheme of rectifier unit of actuation based on thyristors has been unchangeable for more than 45 years. Analysis of electric locomotives’ operation under the regenerative braking has shown that the use of thyristors in the arms of rectifier units of actuation, as well as the adopted methods of control are one of the causes of reduction of capacity factor of locomotives, using recuperative braking (till not more than 0,65 during operation). The article suggests changing of power circuit of rectifier unit of actuation, using new circuitry and control technique, which will allow to raise power factor of AC electric locomotive at recuperative braking by 5%.
