Analysis and testing of wind farm power quality in Inner Mongolia

With the wind power generation in power system increase gradually,the problem of power quality which caused by grid-connection is becoming more and more serious. Power quality indexes of 100 MW wind farm including voltage deviation, harmonic.Three-phase unbalance and voltage flicker were made real-time monitoring in Inner Mongolia. Data analysis displays that the wind farm can satisfy the standard of power quality. Researches show that power quality´s testing of the wind farm can improve the reliability of the power system stabilization. Moreover,it is beneficial to the wind turbine´s security,stability and preventive maintenance.
