Design and Installation of Wind Farms (DIWF)
In order to produce electrical energy from wind in an economically efficient way, optimal planning of wind farms taking into account installation concepts is of utmost importance. The engineer has to know which authorities to work with in order to receive the manifold permissions required for wind farm erection. Besides, he has to be able to perform a realistic energy yield assessment considering different losses and uncertainties in order to convince possible investors of a wind energy project. The module DIWF prepares students for these challenges for both onshore and offshore environments.
The module gives 6 CP and takes place in Winter Semesters. The lectures are mainly given by experienced engineers from industry.
Dr.-Ing. Patric Kleineidam, External Lecturer, Lahmeyer International GmbH, Bad Vilbel
Dr. Patric Kleineidam works for Lahmeyer International GmbH since 2005 and heads the department of wind energy. The department supports the development and realisation of onshore and offshore projects worldwide. Dr. Kleineidam is involved in several national and international wind farm projects, e.g. in Brazil, Egypt, France, Germany, Korea, Morocco, Pakistan and Portugal. This proves his broad experience in wind farm planning and design and his deep insight into the general market structure. Dr. Kleineidam is civil engineer. Until 2005, he was research fellow at the Institute of Steel Construction at Leibniz Universität Hannover and has made his PhD in wind energy engineering in the area of support structure design for offshore wind turbines.
Further guest lecturers from the wind energy industry teach their know-how in different topics of offshore wind energy.
- Practice-oriented insights from lectures given by industry experts
- Deep understanding of calculation methods for wind farm planning and design
The module DIWF teaches manifold competences around onshore and offshore wind farms. After successful completion the students can
- explain the steps of wind farm project development,
- explain the German legal requirements,
- create a wind statistics on the basis of measurements,
- create a wind farm layout and explain the possibilities of layout optimisation,
- calculate the annual energy yield of a wind farm,
- choose wind turbines for specific site conditions,
- explain the installation processes of offshore wind farms,
- name and explain the transport processes for wind turbine components and the logistics issues,
- and explain the processes and safety aspects of wind farm installation.
The lectures of the module have the following content:
- Legal aspects and requirements of wind farm planning and erection in Germany
- Fundamentals of energy yield estimation
- Site-specific choice of wind turbines
- Aspects of wind farm layout optimisation
- Requirements for serial manufacturing of wind turbine components in factories
- Transport processes of support structures and wind turbines in offshore wind farms
- Installation of wind farms: Logistics issues, processes and safety aspects
In the tutorials, students deepen the knowledge gained in the lectures by executing calculation examples. In parts, students do their exercises on the computer in the CIP pool. Students learn to apply the methods for evaluation and preparation of wind measurement data. For this purpose, basic know-how in MS Excel are required. The content of the tutorials is e.g. statistics of wind velocity and direction as well as so-called "measure-correlate-predict" methods for creating long-term wind statistics based on short-term measurements. Furthermore, energy yield calculation in the wind farm including wake losses and uncertainties are discussed.
The tutorials serve to prepare the students for the home work, which is part of the exam.
For the successful completion for the module, students have to take a two-stage exam. The first part is the preparation of a home work, in which the learned knowledge is applied. For this purpose, students create a wind survey, prepare a wind farm layout, and calculate the annual energy production taking into account various uncertainties. The second part is an oral exam which lasts approximately 20 minutes. The overall grade is calculated as the arithmetic average of both parts.
Students have to subscribe to the exam in due time at Akademisches Prüfungsamt (APA). The exam is interpreted as started when the task description of the home work is handed out.
