This paper present a dc-Link voltage regulation strategy for a two-Level three-phase grid-connected power converter. Control objectives for this system are regulating the dc-link capacitor voltage to a user define set point and, tracking the grid current reference to inject or absorb the requested instantaneous active and reactive power. The proposed voltage controller has a PI Control structure, with adaptation of the gains depending on the observed error. In this way, the monitoring of the voltage reference can be intelligently optimized.

摘要

This paper present a dc-Link voltage regulation strategy for a two-Level three-phase grid-connected power converter. Control objectives for this system are regulating the dc-link capacitor voltage to a user define set point and, tracking the grid current reference to inject or absorb the requested instantaneous active and reactive power. The proposed voltage controller has a PI Control structure, with adaptation of the gains depending on the observed error. In this way, the monitoring of the voltage reference can be intelligently optimized.
