Series compensators can be used to solve a number of power quality issues in electrical distribution systems. These devices are connected in series between the point of common coupling and a load and they inject a series ...

Electronic Power converters have a great potential in power quality applications in electricity distribution networks. This paper presents a comprehensive control strategy for Unified Power Quality Conditioners (UPQCs) to ...

Voltage sags result in unwanted operation stops and large economical losses in industrial applications. A dynamic voltage restorer (DVR) is a power-electronics-based device conceived to protect high-power installations ...

En este proyecto se han desarrollado controles adaptativos proporcional y proporcional integral por programación de ganancia (gain-scheduling). Se ha optado por la adaptación del control porque al realizar el modelado ...

Dynamic Voltage Restorers (DVRs) are a cost-effective solution to protect sensitive loads against voltage sags in medium- and high-power applications because the power required for the compensation is only a fraction of ...

Repetitive controllers are used to track periodic references or to reject periodic disturbances, exactly. When implementing this type of controllers digitally, the sampling period has to be chosen so that there is an integer ...
