CONTROL OF POWER ON A LARGE DIESEL ELECTRIC LOCOMOTIVE OF NEW DESIGN

To control the power of a large locomotive effectively the driver must be provided with some form of automatic control of tractive effort and engine power. This must ensure that the engine is never overloaded, and that the most efficient use is made of the available adhesion. Some details of load control are discussed from a stability point of view, and ways and means of using the available power are discussed. An ideal characteristic is proposed and the limitations of existing machine systems are described. A description of a locomotive, in which the principles described were used, is given with a block diagram of the control system. A simplified schematic diagram of the control system used is given, and the function of the principal elements in it is explained. Finally, the paper draws some broad conclusions from the experience gained during operation of the system in service.
