Fluctuation Voltage Control of Wind Turbines via STATCOM

Abstract

This paper presents distributed STATCOM for controlling voltage in distribution line with wind turbines generations at 48 volts. The connection of wind turbine to distribution systems may affect the voltage quality offered to the consumers. One of the factors contributing to this effect is the rapid variations of the wind turbine output power, which cause respective fluctuations in the supply voltage. This paper presents the design, control and analysis of a Distributed STATCOM when combined with a wind turbine comprising small variable speed generators, in this paper it is shown that the distributed STATCOM, controlled via a rotating referent frame: RRF and recursive DFT are simple method to DSP control technique. The result of experiments the STATCOM can improve the transient stability voltage of wind turbine that we have referred the IEEE1159:1995 standard of power quality.
