ABSTRACT OF THE DISCLOSURE An excitation and power control system for a diesel engine-generator unit of a locomotive including a programable logic controller for processing input signals received from a throttle lever switches module, a load regulator module, a wheel slip transductor module and a performance control module, and generates output signals which control an engine speed governor and a sensor module. The load regulator module is controlled by the engine speed governor according to a set throttle lever position and generating a signal representative of a required power output and the performance control module processes a feedback current and voltage signals from a main generator, representative of a measured power output signal. The sensor module controls the excitation current of said main generator, and a wheel slip transductor module is provided for detecting wheel slip condition, wherein the excitation current to said main generator is a function of difference between the required power output signal and the measured power output signal. A traction motor is located on a locomotive axle.
