This article proposes a new control scheme for a distributed cogeneration (microcogeneration) plant using a 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 in the dc side. During grid-connected operations, the same converter can be used for power factor correction. Energy generation and its optimal use are the key issues in actual social conditions. In this framework, the European Union (EU) anticipates that the amount of energy produced by cogeneration plants will double within five years, and this might be an underestimated growth, as its potential is still unexploited. Cogeneration or combined heat and power (CHP) means the combined production ofthermal, electrical, and mechanical energy.Recently, distributed cogeneration or micro-CHP was constantly in the spotlight of the industrial and scientific community.

Abstract

This article proposes a new control scheme for a distributed cogeneration (microcogeneration) plant using a 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 in the dc side. During grid-connected operations, the same converter can be used for power factor correction. © 2009 IEEE.
