Control of Electrical Power Generation and Conversion on Aircraft and in Modern Wind Turbine

The aircraft and wind turbine applications are of major concern in the reduction of dependency on fossil fuels. Efficient and reliable electrical power systems are in great demand in both aircraft and wind turbine industrial sectors. The electrical power systems of the aircraft and the wind turbine have experienced dramatic developments in the past decades that continue until date. Due to the demand of innovative solutions, the focus on these applications in this work is made in order to explore more technological advancements, which in turn may lead to further steps in achieving the right solutions demanded by both the aircraft and the wind turbine industries.
In the first part of this thesis, the aircraft electrical power system based on HVDC - High-Voltage Direct Current based on the Two-Generator Engine is discussed, as such an electrical system is one of the main technological advancements towards improving the performance of the future aircraft.
In the second part of this thesis, the electrical power generation and conversion in modern wind turbines is investigated, based on an efficient medium-speed synchronous reluctance drivetrain with modest power rating proposed for the variable-speed wind turbine application. The synchronous reluctance generator with full-scale three-level neutral point clamped voltage source converter is analyzed for wind turbine systems where the high efficiency, high reliability and low cost are the main concerns.
