Book Description:
Among
renewable sources wind power systems have developed to prominent
s- pliers of electrical energy. Since the 1980s they have seen an
exponential increase, both in unit power ratings and overall capacity.
While most of the systems are found on dry land, preferably in coastal
regions, off-shore wind parks are expected to add significantly to wind
energy conversion in the future. The theory of modern wind turbines has
not been established before the 20th century. Currently wind turbines
with three blades and horizontal shaft prevail. The
driven electric generators are of the asynchronous or synchronous
type,with or without interposed gearbox. Modern systems are designed for
variable speed
operation which make power electronic devices play an important part in
wind energy conversion. Manufacturing has reached the state of a
high-tech industry. Countries prominent for the amount of installed wind
turbine systems feeding into the grid are in Europe Denmark, Germany
and Spain. Outside Europe it is the United States of America and India
who stand out with large rates of increase. The market and the degree of
contribution to the energy consumption in a country has been strongly
influenced by National support schemes, such as guaranteed feed-in
tariffs or tax credits. Due to the personal background of the author,
the view is mainly directed on Europe, and many examples are taken from
the German scene. However, the situation in other continents, especially
North America and Asia is also considered.
