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.
