Nowadays the needs concerning energy consumption are becoming increasingly demanding. The ever growing requirements for more reliable and cost efficient systems also apply to traction systems. On one hand vehicles have the capability of dynamic braking that allows the energy to be returned to the traction grid and utilized by other vehicles. On the other hand, very often substations are integrated...
This paper proposes an advanced control of three-phase three-level neutral point clamped (3L-NPC) PWM converter connecting a permanent magnet synchronous generator (PMSG) to a grid. Control scheme is mainly based on active and reactive power loops and contains following additional blocks: virtual flux and filter-capacitor voltage estimators for sensorless operation, active damping (AD) of possible...
