In a world where resources are becoming scarce, there is a high demand for renewable energy. Development has been made for more efficient and effective energy resources that are cheaper and more reliable than current methods of energy production. With new innovations arising in combination with current resources depleting, the world is turning its attention to wind energy in order to aid the sustainability of energy needs. Wind energy, as a rule of thumb, is a clean, renewable and environmentally friendly source due to the fact it is naturally generated. With that knowledge, our goal of this project is to design and implement a system that can harvest this energy source and convert it into AC power.  Through a variety of power electronics, digital signal processing and controls we can utilize these tools to achieve this feasible goal.


Complete System Description

This particular system converts wind energy into electrical energy using components such as a permanent magnet synchronous generator, a diode rectifier, a two interleaved boost converter, and a voltage inverter as depicted in Figure 1. The system will begin by harnessing kinetic energy from wind that will rotate the blades of a permanent magnet synchronous generator creating mechanical power. The electrical energy produced from the permanent magnet generator will be output as three-phase AC. From this output, another conversion from AC to DC will take place through the use of a three-phase rectifier that will enable the use of a boost converter to boost our DC voltage. In order to boost the voltage that will be needed to supply the grid, we will use two interleaved boost converters. The DSP board will be responsible for handling the switching process of the boost converters. Moving from the boost converters we will perform yet another conversion from DC to AC by an inverter. Finally, this AC will be supplied to grid power.
