KIEPE Traction Control KTC
The KIEPE Traction Control Software KTC represents a further development of the drive control for rail vehicles and is characterized by the following features:
- Fast torque control in every operating situation.
- Improved efficiency by using synchronous pulse patterns in the upper speed range. This increases the overall efficiency of the traction machine and traction converter.
- Optimized wheel slide and slip protection.
- Reduction of noise and energy consumption with optimized machine flux control.
- Reduction of acoustic resonances in drivetrain and in braking resistor by optimized switching frequency modulation.
- Optimized driving characteristics in condition of icy overhead line.
- Reliable and stable start on very high inclines.
- Highest priority on electrical braking capability, even in case of the overhead line voltage failure.
- High recuperation level and protection against consumption of the external energy.
- Controlled acceleration and deceleration at different loads and road profiles.
- Traction operation on 24V-DC-link voltage for low speed and rescue drive mode.
Drive control features of KTC
- Active damping of torsional oscillations in a drivetrain of electric buses (Patent pending)
- Very dynamic electronic ASR (inside of inverter control)
- Variable switching frequency (frequency band modulation)
- Reduction of subjective and objective acoustic noise perception
- Optimized system noise
- Special control algorithm for acceleration at very high inclines (up to 22 %)
- HighPriority on electrical Brake capability (until zero speed)
- Overmodulation with synchronous pulses (+15 % machine voltage), lower energy
- Energy optimized drive mode (optimal machine flux at lower torque)
- Acceleration Control
