Abstract:
According to one embodiment, an electric train control apparatus having a plurality of electric motors and a plurality of inverters configured to control electric motors, independently of one another, including shaft speed calculating units respectively, and configured to calculate shaft speeds of electric motors, reference speed calculating unit configured to calculate a reference speed from shaft speeds of electric motors, acceleration detection control units configured to calculate torque reduction values from rates at which shaft speeds calculated, slip speed control units configured to reduce torques in accordance with a difference between shaft speeds of electric motors, state monitoring units configured to monitor states of detecting shaft speeds and output state signals, and changeover unit configured to switch control of inverters, between control performed by acceleration detection control units and control performed by slip speed control units, in accordance with state signals received from state monitoring units.
