Induction motor drive with inverter control, which can reduce the total weight of the system, has been introduced to the Shinkansen trains in order to achieve high speed transportation.The individual-motor-control type 953 train, which is a part of the STAR21 prototype Shinkansen for high speed experimental run, was used for measurement running, in which we observed wheel slip and adjusted re-adhesion control parameters at the speed of 200 to 300km/h. It was found that the slip detection within one percent speed difference from the reference, was possible by adopting sensitive detecting method. Quick torque reduction by sudden reduction of motor current was necessary for re-adhesion control, and one-second waiting time before re-applying current was also inevitable. For re-applying the current, an exponential curve with four-second time constant was proved to be effective.By these tests, high speed performance and re-adhesion characteristics improvement by adjusting control parameters were obtained. To the next step, for example creep control, which utilizes fine continuous slip, should be investigated in order to keep enough torque minimizing current reduction during re-adhesion control.

This paper describes improvement for wheel slip and re-adhesion control for electric locomotives with induction motor vector control. Compared with the conventional slip frequency method, the torque response is much improved by the vector control. By referring the re-adhesion process for the traditional rectifier controlled do-motor locomotives, suitable torque reduction to an induction motor is applied in accordance with the wheel slip speed. The test results by the series EH500 locomotive for Japan Freight Railway Company, show much improvement for the re-adhesion process especially when a steeper torque reduction ratio is applied.

For the better performance and/or the high speed running for electric rolling-stocks, high accuracy power factor control with PWM power converter fed by ac power line has become popular. It is practically easy to control actual power factor itself at the input point of the power converter on the rolling-stock, however, the more important is that at substations. Although there are some technical difficulties for detecting the correct voltage phase angle on the train, caused by, for example, interference from thyristor controlled converters, suitable target value for practical power factor can be calculated under reasonable conditions. Among some kinds of control concept, the instantaneous current control referring sinusoidal waveform is the most suitable solution for the Japanese Shinkansen. The test results proved the expected power factor control performance.

Induction motor drive with PWM inverter control, which can reduce the weight of the driving devices, is used for Shinkansen trains in order to achieve high speed transportation.This paper describes the experimental results for controlling wheel slip and re-adhesion at high speed running with the type 953 Shinkansen test train. The induction motor for each axle of this train is individually controlled by an independent PWM inverter. By introducing the vector control for the induction motor drive system, quick response for the motor torque can be achieved when wheels are going to slip. The control scheme for the wheel slip and re-adhesion is that the motor torque is gradually reduced by increasing of wheel slip speed.The results show, it is possible to recover to adhesive condition against wheel slip, without excessive motor torque reduction, when the reducing torque value and control time constant are properly selected.By these tests, re-adhesion characteristics improvement by induction motor vector control are obtained. To the next step, the parallel motor control system with a vector controlled inverter will be investigated.
