The aim of this lecture course (6 ECTS) is that students understand the physical principles of wind energy and the technology of modern wind energy systems. It consists of lectures and exercises, and is given by Prof. Dr. Moritz Diehl and Nick Harder.
- global wind energy resource
- aerodynamic principles of wind turbines
- design of modern wind turbines
- control of modern wind turbines
- the electrical system of wind turbines
- alternative concepts and airborne wind energy
Due to Corona regulations the lectures and the exercises will take place online (at least until the mid of June) using Zoom Platform.
The first lecture will be held on 12.05.2020 (Tuesday).
The course will be held on:
- Tuesdays 12:30 - 14:00h
- Wednesdays 12:15 - 14:00h
Please, use the following link to access the class for both lectures and exercise sessions. Password: 5BCxhi3Xm
The lectures will be recorded and posted on this webpage.
The Wind Energy Systems (WES) course has two modes of instruction: lectures and exercises. The lectures are given by Moritz Diehl. One biweekly time-slot is dedicated to an 'exercise session' that will be coordinated by Nick Harder (firstname.lastname@example.org).
The exercise sessions are held on a biweekly basis. First exercise sheet will be provided on 20.05 after the lecture. One week after you receive the exercise sheet a video recording of the exercise solution will be posted on this webpage, and another week later an online exercise session will take place, where you can ask questions to the previous exercise sheet and a new exercise sheet will be provided. The exact schedule can be found below.
The grade for the course corresponds to the grade of the final exam. This final exam is 'closed-book,' which means that ONLY pens, a calculator, and one A4 page (that is, two sides) of notes can be used. The questions will be partially multiple-choice and partially short-answer.
