ABSTRACT:
A control system for an AC diesel electric locomotive allowing for continued operation of the locomotive even in the instance of failure of current sensors providing current feedback information. The system is coupled to a plurality of DC to AC inverters with each of the inverters being connected for supplying controlled AC power to at least one AC electric traction motor coupled in driving relationship to wheels of the locomotive. The control system controls the power output of the inverters in response to an operator's command and to sensed operating conditions of the locomotive. One of the sensed operating conditions is power output of the converter determined by measuring its voltage and current output, the latter measurement using a series connected current monitor. The system incorporates apparatus for sensing failure of the current monitor and, in response thereto for modifying the control system to substitute a selected value for the sensed power output of the converter.
