Design a Grid Tie Inverter for PMSG Wind Turbine using FPGA & DSP Builder

Abstract

The recent makeshift in fuel choice, renewable energy sources has been considered as the most popular form of its kind because of its environment friendly approaches, less cost tariff policy and the natural fuel abundance. This inclusion in power system promotes Micro-grid system to optimize the overall distribution. FPGA, elaborated as Field Programmable Gate Array, proposes chances for enhanced performance and coveted flexibility in design for the digital control. Conversely, the erudite convolution of the Hardware Description Language (HDL) coding, a way translating to HDL, can be an undesirable hurdle for the professional system designers. The design, depicted in this letter, is an instance of system modeling for FPGA-based digital control, which necessarily has the desired ability to auto-generate the HDL codes. The architecture of this design uses the DSP Builder technology, in a MATLAB / SIMULINK platform. A three phase full-bridge gird tied inverter for wind system and a three phase full-bridge inverter for grid connected wind system are built that demonstrates the close correlation with the model. The necessary simulations, results and the experimental analysis have also been highlighted for the different control techniques such as PI, dq, and the PWM control technique.
