Abstract: |
With the continuous expansion of wind farms installed capacity, wind farms impact on power system voltage will become increasingly evident. From the VSCF wind turbine characteristics, this article was built the model of VSCF wind turbine to the grid based on Matlab / Simulink. This article analyzes the process of wind turbine output increases, the maximum output, the output reduction process. It analyzes wind turbine bus voltage, current, active power, reactive power and wind turbine inverter DC side voltage and other parameters change when the system bus voltage drops. It proposed low-voltage protection setting program. It analyzed to improve the wind turbine characteristics of low voltage power through（LVRT）wind turbines with a combination of measures across the power grid and wind turbine.
