| Abstract |
In this paper the authors present an optimal remedial strategy for Inverter - Three phase induction machine system drive faults. Remedial strategy can be a single-phase operation when neutral point of star coupled induction machine is not connected, and is a two-phase operation when neutral point is connected to dc Source Voltage of a Current Controlled lnverter. In this case ripple component, which is unavoidable in single-phase operation, can be supressed when current references are pi/3 shifted. This optimal two-phase operation mode can be used to perform field-oriented control as in three-phase operation. Obtained performances with two-phase operation are then similar to those of three-phase mode but with currents magnitude V3 more important. |
