ABSTRACT:
To obtain a control apparatus for a Diesel-electric locomotive that harmonizes an engine power with a torque command of an induction motor, which is a load of an engine, in the Diesel-electric locomotive and avoids an overload of the engine.
A cooperative controller 15 is provided, the controller 15 which receives a notch signal N, an engine speed command value n* corresponding to the notch signal N, an engine speed n, and rotating speed fr of an induction motor 17, calculates a torque command value Tp corresponding to the engine speed n from torque command values before and after the notch signal changing during response time for control of the engine speed if the notch signal N changes, and calculates the torque command value Tp corresponding to the notch signal N after a notch is changed, except the case thereof. Furthermore, the torque command value Tp is outputted to an inverter controller 20.
