Effect of PLL Structure on Equivalent Output Impedance of Grid-Side Inverters in Offshore Wind Turbines: MSc Thesis Report

Offshore wind power plants are subject to adverse electrical conditions that are more severe than onshore cases, due to the long cable connection to the shore. Among these conditions are amplified voltage distortion at (inter)harmonic frequencies, as well as stability issues. An important aspect of wind turbine generator control is the phase...
