The vehicle (10) has power converters (28-36) for operatively connecting electrical machines (12-20) to a direct-current intermediate circuit (22), where the machines are operated as electric motors or generators. Each power converter includes an identical...

The method involves determining a fundamental oscillation amplitude of substations (11, 12) from measured voltage such that target fundamental oscillation amplitude i.e. voltage amplitude, and a target power factor i.e. average power factor, are predetermi...
