Spiridonov E., Basargina G.In the paper the results of research of imitation model of trolleybus operating in recuperation braking mode are shown. Influence of several factors on the efficiency of recuperation braking such as traction substation voltage, remoteness of recuperated train from traction train, recuperation voltage controller settings is estimated. It is shown that in case of limited traction energy consumption the main influence on recuperation braking efficiency have settings of recuperation voltage controller. The use of relay voltage controller with voltage settings 720 and 700 V is proved.
Keywords: recuperation braking, trolleybus, imitation modeling, recuperation efficiency, follow-up recuperative-resistance braking.
