摘　　要：根据交流传动内燃机车特点 ,提出了利用牵引逆变器实现交流传动内燃机车柴油机变频起动的方案。给出了主电路实现方法。分析和建立了柴油机起动工况的等效电路和数学模型 ,进行了仿真实验。分析和仿真结果表明 ,该起动方案能够完成柴油机起动 ,是经济、合理、适用的。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.
