Effect of Wind Speed Changes on Grid Power Quality at Various Levels of Wind Electric Penetration -A Laboratory Investigation

V.Vanitha and N.Devarajan

Full text: PDF


This paper presents a laboratory study of the effect of wind speed changes on grid power quality parameters such as voltage, frequency, power factor and harmonics at different penetration levels of grid connected wind electric generator (WEG). Linear and gust changes of wind speed are considered in the analysis besides a constant value. The analysis is done on a three phase squirrel cage induction generator (SCIG) coupled to a DC shunt motor in the laboratory. The wind speed change is simulated as a shaft speed change of SCIG. The effects on power quality at various levels of penetration and different types of speed change are compared. Results obtained are compared with field datas and simulation results.
