A Study of the Induced Voltage Detector Designed for the Power Distribution System on 115kV Effecting on 22kV Distribution Line

AbstractThis paper presents a study of the induced voltage detector designed in the power distribution system on 115kV that effecting on 22kV distribution line. Therefore, the studies are the induced voltage detector design and construct of the power distribution system on 115kV, which affects the power distribution system on 22kV and the operation has been its ease of use, check voltage that can be rendered into sound and the lights. The red light the result of the 22kV distribution line and a green light the result of induced voltage of the power distribution system on 115kV

Fluctuation Voltage Control of Wind Turbines via STATCOM

รายงานการวิจัย--มหาวิทยาลัยเทคโนโลยี ราชมงคลพระนคร, 2553This 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.Rajamangala University of Technology Phra Nakho
