DSP Implementation of a Harmonic Reduction Strategy for a DC Link Inverter in a WECS

The use of alternative sources of energy appears to be an indomitable necessity to bridge the gap between supply and demand. Though a series of options continue to surface, solar and wind emerge as a viable and sustainable resources at least for most parts of the year. However the speed of wind driven generators keep fluctuating and invite interfaces to suit the system needs. The prelude endears extra emphasis in the preview of grid connected systems to avoid adversaries. The imminent actions of the power switches along with the presence of non- linear elements in the interfaces join the inductive nature of the load to introduce harmonics in the systems. It becomes essential to address the ill effects of the higher frequency components and ensure a satisfactory environment for the transfer of power. The advent of solid state processors offer a platform to process the signals and realize the design of the control methodology for the purpose of generating PWM pulses. The endeavor extends to articulate the DS processor with a function to shape the trigger pulses for the active devices in the dc link inverter in order that it eliminates the multiple frequency components and serves to enhance the fundamental component of the output voltage.
