| Summary | This course covers the fundamentals of electrical machines, power-semiconductor technologies, & power conversion techniques. It examines the main types of machines currently used in renewable energy (squirrel cage and doubly-fed induction machines, and both field and permanent magnet (PM) excited synchronous machines) along with use of pulse width modulation (PWM) controlled AC-DC-AC converters to connect to the grid, linking generators to power conversion. Students will be guided through a detailed design exercise on PM generators for direct drive offshore renewables. In power electronics, the design & control of machine and grid interface converters will be discussed in detail. In the lab students will develop oscilloscope and measurement skills, as well as an appreciation for the system integration work that is required to implement a practical power-electronic converter, and to determine the performance characteristics of electrical generators. As part of the course students will visit SSEN's HVDC Centre. |
