The objective of this project is to design a 100kW 4-quadrant inverter as a reliable and efficient interface between wind turbines and diesel grids, in collaboration with industry partner, Frontier Power Systems Inc. (Frontier) in PEI. The major tasks of the project include the design of an advanced excitation control strategy for wind turbine induction generators, development of a maximum power point tracking algorithm for wind turbines operating at variable speeds, development of a DC-link voltage control approach to regulate the output power feeding into the diesel grid. Frontier is expanding its business across North American in wind diesel systems, using induction generator based wind turbines. However, a major challenge faced by Frontier is developing a reliable and cost-effective inverter specific to interfacing induction generator based wind generation systems with diesel grids. The proposed 100kW 4-quadrant inverter designed under this project will provide an integrated solution for Frontier wind-diesel systems, which will improve Frontier's competitiveness in the market of wind-diesel systems by offering a reliable, cost-effective wind power option for remote communities to meet electricity demands. This ENGAGE project will strengthen the long term partnership between UNB and Frontier, and will subsequently lead to long term R&D projects in renewable energy applications. This research project will enhance training for highly qualified personnel including a Ph.D. student and a post-doctoral fellow. Both the applicant and the industry partner are committed to the success of this project and to the long term R&D collaboration.
