Abstract
A feedforward voltage series compensator based on complimentary use of wind, solar, and electric power comprising a controller, a rectifier unit, an H bridge inverter, a series transformer, a wind-power DC voltage sensor, a wind-power DC current sensor, an AC voltage transducer, a DC boost unit, a PV DC voltage sensor, a PV DC current sensor, and a grid-connected inverter. The compensator makes use of wind-electric and photovoltaic-electric complimentary interactions to solve the traditional energy issue for series compensator, and as the grid-connected inverter is feedforward, there is extra capacity for the series transformer and the series complimentary inverter unit, and hence it enjoys the feedforward and quick voltage complimentary characteristics of the wind and solar power generation.
