You will be asked to design a high-efficiency alternator for a wind turbine. The alternator must be capable of producing a minimum of 10 MW of power at a wind speed of 375 rpm, with an efficiency of at least 95%. You will need to consider factors such as the number of poles, winding configurations, and cooling methods to optimize the design for the specified requirements.
Instructions:
1. Conduct a literature review on the design and operation of alternators, focusing on factors that impact efficiency and power output. (Make a table of the recent five research articles)
2. Develop a model for the alternator, including calculations for the number of poles, the size, the number of slots, number of windings etcetera.
3. Describe appropriate factors that affect the size of the alternator, such as efficiency, Power output, cooling system, speed etcetera (Describe with proper example).
4. In a wind power plant, there are a number of wind turbines. Describe in detail, how they are connected with the national grid (schematic view of nacelle and overall connection).
5. Is it important to make a parallel connection of all the nacelles before making a synchronization with the infinite bus? Describe the procedure how it can be connected and synchronized.
Design the alternator with overall conditions using any convenient way or simulation software.
