Objectives
The
objective of this course is to give the participants a platform for the
exchange of scientific and technical information related to components
selection, design and modelling of electromagnetic transients in the collection
and export power system of large offshore wind farms.
In this course the following topics will be addressed:
- Switching transients
- Insulation coordination
- High voltage cables
- Power transformers
- Circuit breakers
- Wind turbines
- Protection systems
- Mitigation methods
- Offshore substation
- Electrical transient interaction
Large offshore wind farms are based on extensive MV submarine cable collection
networks connecting hundreds of identical WTs, placed in regular patterns
with certain interspacing. Each WT is connected to the MV network through
a step-up transformer and switchgear. The collection grid is connected
to a transformer station which in large wind farms is usually also placed
offshore at which the voltage is raised to high voltage for transmission
via a submarine export cable to a connection point in the public power
grid on land up to more than hundred kilometres from the offshore wind
farm.
Such arrangements are unusual as compared to a typical expansion of a
power system in several ways such as: the lateral sizes of the systems,
the large number of identical sub systems: generators, power converters,
transformers, and switchgears in the wind turbines and collection network;
and also unusual compared to other power system´s operating conditions
and environmental constrains.
Regarding the modelling of MV and HV equipment for electromagnetic transient
simulation studies, there is fair amount of information and guidelines
available in the literature about circuit breakers, transformers, cables,
surge arrestors etc.; this however tend to be mainly theoretical information,
and in practice the information about these components is typically not
available in sufficient detail for accurate insulation coordination studies
. Furthermore, commercial simulation
tools tend either to have limited facilities for this type of studies
or require very specialized training and experience. In short, the credibility
of this type of studies relies on the quality of the models and information
that the user can get hold of, and even then, it depends on the simulation
tools and the user’s skills. This creates additional concern and
further work is necessary to design the collection grid of wind farm with
the high reliability, needed for offshore wind farms

Prof. Rodrigo Garcia (rgv@lektro.dtu.dk)
Rodrigo
Garcia was born in Mexico. He received the electrical engineering degree
from the National Polytechnic Institute of Mexico, in 2001, the M.Sc.
degree from CINVESTAV, Mexico, in 2003 and obtained his Ph.D. degree from
the University of Glasgow, U.K., in 2007. In 2008, he was granted with
the Hans Christened Ørsted Award at the Centre for Electric Technology(CET)
by the Technical University of Denmark to carry out postdoctoral research
activities. Since 2009 he holds the position as Assistant Professor. His
research interests are dynamics, stability and control of electric power
systems; renewable energy integration; and modelling and simulation of
FACTS and custom power controllers. He is an IEEE, IET and CIGRE member.
Joachim Holbøll is an Associate
Professor with many years experience within on electric power components,
modelling and performance. He has been supervisor for PhD projects for
many years.
