The construction of the Wu Shan
Tou Reservoir took almost ten
years, from 1920 to 1930, but when
completed it not only had a major
impact on the rural society of the
time, but also supported Taiwan’s
economic development.
For more than 80 years, irrigation of
over 100,000 hectares of farmland on

By beginning of July 2012 ANDRITZ
HYDRO received from VA Erzberg
GmbH the order for the delivery
and installation of a vertical
Pelton/Generator unit. Putting
into operation is scheduled by
end of March 2013.
The scheme station is a run-off-river
power station in the iron ore mining
of the Erzberg in Styria, Austria. Via
collectors of the Reichenstein spring,
inlet basin, penstock (DN 500 mm,
approx. 4,044 m long) flows the
water to the power house, which is
equipped with a 4-nozzle Pelton
the Chia Nan plain in the west of Taiwan
has functioned independently of rainfall,
and a continuous crop supply can be
assured. Due to its uniqueness and importance
to Taiwan’s development, the
Wu Shan Tou reservoir is even being
considered as a potential World Heritage
site.
In 2002 a vertical Kaplan turbine, supplied
at that time by VA Tech Hydro,
was started up, with a runner diameter
of 2.35 m and a power of 9 MW.
turbine, generator (2,000 kVA, 690 V),
control system as well as the transformer
and medium voltage equipment.
The power transmission to the
10 kV grid of VA Erzberg GmbH will be
done by a buried power cable up to
new transformer station and in addition
connected to the public network.
In the year 712 a document mentioned
for the first time in writing the mining
of the ore mountain. Even today this is
the most important economic basis in
this region. Currently, every year approximately
2 million tons are ore
Thus the storage height and the water
retained by the dam added up to
additional and valuable power production.
In order to extend the
usable water flow, the customer,
Chia Nan Enterprise Co., entrusted
ANDRITZ HYDRO again with supply of
a Compact Axial Turbine CAT1200.
In memory of the young engineer who
designed it and was responsible for
the construction of the Wu Shan Tou
reservoir, the new plant will carry his
name: Pa Tien.
