【Abstract】 According to the character of diesel locomotive of AC transmission, a scheme is put forward to realize the frequency conversion start up of gas engine for diesel locomotive of AC transmission with traction inverter. The realization method of the main circuit is presented. The equivalent circuit and mathematics model of the start up work status of the diesel engine are analysed and established, and carried through the imitation experimentation. The result of the analyses and the imitation indicate that the start up scheme can complete the start up of diesel engine, and it is economical, reasonable and applicable.更多还原
