Abstract :
The performance of a drive and the quality of torque control in DTC depend on the accuracy of the estimation of flux linkage. For applications with dual-star machine each stator winding is supplied by its own inverter and the adequate stator fluxes are built. The full redundant drive is the latest development of ABB drives based on the DTC control platform. In the paper the motor model for a dual-star synchronous machine is discussed. Based on simulations with the Simulink/Matlab model of the redundant drive the operation of the drive was confirmed. Further, the concept was verified with a 1 MW motor and two ACS6000 converters in laboratory environment.
