Abstract :
This article proposes a new control scheme for a distributed cogeneration (microcogeneration) plant using three-phase induction machine as an electric generator. This control scheme assures a better energy-conversion quality. The plant can be operated as a grid-connected generator with load tracking or as an isolated generator. In isolated operation, the induction generator is excited with a current-controlled voltage source inverter (CCVSI) having a suitable capacitive bank the DC side. During grid-connected operations, the same converter can be used for power factor correction.
