Abstract
Onshore and offshore wind power plants comprising wind turbines equipped with power converters are increasing in number worldwide. Harmonic emissions in power converters distort currents and voltages, leading to power quality problems. Low order resonances in the collector grid can increase the impact of wind turbine emissions. These resonances may also produce electrical instabilities in poorly damped wind power plants. The paper performs frequency scan with Matlab/Simulink simulations and compares low order frequencies of parallel resonances in onshore and offshore wind power plants. It also investigates the influence of wind power plant variables on resonance. Finally, simplified equivalent circuits of wind power plants are proposed to study low order parallel resonances.
