Output Filter Design of Grid-Connected Inverter for High Power Offshore Wind Power System

Output Filter Design of Grid-Connected Inverter for High Power Offshore Wind Power System
 The output filter design for high power grid-connected inverter of offshore wind-turbine has many limitations such as low switching frequency, allowable DC-voltage, and the component volume and weight. In addition, the injected harmonic current into the grid is constrained by various grid connection requirements. This paper compared and weighed with several harmonic regulations and suggested the optimal design procedure of the output filter compliance with the grid code using spectrum analysis of inverter output voltage that contains harmonics. In this paper, the output filter of grid connected inverter for 7MVA offshore wind power system is designed to meet the BDEW harmonic currents limits and the IEEE 519-1992 requirements. The performance of the designed output filter is validated by extensive simulations using Matlab/Simulink.
