The Plant
Pasir Gudang Power Station is a gas-fired CCPP
in Malaysia, which is operated by YTL Power
Services. It consists of two gas turbines, two
heat recovery steam generators and one steam
turbine with a total power of 404 MW. The first
unit was commissioned in 1994 and the last in
1995. The plant supplies power to the national
utility company Tenaga Nasional Berhad.
The Task
Due to the aging excitation system and startup
frequency converter of unit 11 in Pasir Gudang,
the spare parts, repairs and services became
obsolete. In case of a failure YTL Power would
not be able to operate the gas turbine, which
would affect the availability of the whole plant.
To reduce this risk and ensure the availability
of the plant, the aging technology needed
to be upgraded.
Our Solution
With SPPA-E3000 Excitation Systems and
Startup Frequency Converters we offered
a technical solution that meets the footprint
and customer requirements in Pasir Gudang.
The aging components were replaced by the
newer version D03 of SPPA-E3000 SES Type
SEMIPOL, which was designed and configured
to the power plant environment. Not only that
the latest digital technology is incorporated in
the system, it is also supported for 15 years in
spare parts. Through a additionally guarantee
of repair until 2030 and services up to the year
2034 the obsolescence risk was reduced,
whereas availability was considerably increased.
Thanks to our optimized project implementation
we delivered, installed and commissioned the
solution according to customer‘s planned
outage.
“The local competency to
execute the project convinced
us to conclude the contract with
Siemens. Now we are pleased
with the result: A solution with
the latest technology, that
meets the footprint and ensures
long-term support – realized
within a short amount of time.”
