Analysis on the Wind Turbines Current Influenced by the Impedance Variation of Low Voltage Ride through Test Device

Abstract:

To analysis the low voltage ride through tests results carried out in Inner Mongolia, the impedance model of low voltage ride through test equipment ability with the wind turbine is established. The grid current variation caused by series or parallel impedance switching is analyzed theoretically. Results show that grid current will become larger while the parallel impedance of low voltage test equipment is smaller. Consequently, suggestion is proposed to take optimal configuration of impedance in the equipment to reduce effect on grid current, which can ensure the smooth running of low voltage ride through test.
