A Study Of Single Phase Multi Level Inverter With D Statcom For Grid Connected Wind Turbines

VIJAYALAKSHMI A K, Dr.K.S APRAMEYA::This paper presents the design and comparison of multi-level inverter with D-STATCOM for wind energy systems using Modular Multi-level Converter (MMC). The aim of the work is to design different levels of inverter with FACTS devices to provide utilities with more knowledge about the distribution systems, specifically at the end points. Hence made the comparison between these levels of inverters where the output of the system does not vary with the levels of inverter but the Total Harmonic Distortion (THD) of the system will reduces as the level increases. This inverter is placed between the wind turbine and the distribution grid where the active and reactive power is regulate which is required by the grid. Simulations of the proposed inverter with 5 level and 7 level have been done in MATLAB/Simulink. The simulation results validate the performance of the proposed control strategy.
