This paper deals with the control of a distributed cogeneration (micro-cogeneration) plant using a three-phase induction machine as electric generator. The plant can be operated as a grid connected generator with load tracking or as isolated generator. In isolated operation the induction generator is excited with a Current Controlled Voltage Source Inverter (CCVSI) with a suitable capacitive bank in the DC side. During grid connected operation the same converter can be used for power factor correction. The control scheme relies on air-gap flux field oriented control based on ADMC401 DSP. A better energy conversion quality is achieved thanks to the control of the exciting current component. This allows to obtain higher efficiency, higher control dynamic and a very robust behaviour in case of transient variation of the prime mover speed.

Abstract
This paper deals with the control of a distributed cogeneration (micro-cogeneration) plant using a three-phase induction machine as electric generator. The plant can be operated as a grid connected generator with load tracking or as isolated generator. In isolated operation the induction generator is excited with a Current Controlled Voltage Source Inverter (CCVSI) with a suitable capacitive bank in the DC side. During grid connected operation the same converter can be used for power factor correction. The control scheme relies on air-gap flux field oriented control based on ADMC401 DSP. A better energy conversion quality is achieved thanks to the control of the exciting current component. This allows to obtain higher efficiency, higher control dynamic and a very robust behaviour in case of transient variation of the prime mover speed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
