摘　　要：介绍一种对我国内燃机车主发电机励磁机组控制方式进行改进的方法,提出使用三相整流技术控制主发电机励磁的观点。详细阐述了主发电机恒功率控制和整流桥触发控制的原理,对装置进行了模拟试验。结果表明该方法有利于改善励磁系统的响应速度和稳定性,能够提高柴油机的效率,完全满足内燃机车恒功控制的要求。The modified method for the control of excitation set of the main generator for diesel locomotive is introduced. The opinion to control the excitation of main generator with three phase rectifed technology is forwarded. The principle of constant power control of main generator as well as the triggering control of rectifier bridges is elaborated. Analog test is done to the device. The results show that the method is good for improvement of speed and reliability of excitation system and for improvement of efficiency of the diesel engine, which fully conform to the requirement for constant-power control of diesel locomotive.
