“The key benefit for our
customers is providing them
with reliable information on
the potential operational
capability of their generators
under simulated operating
conditions, with engineering
and manufacturing
right next door.”
Axel Blinn
Head of Turbo-Generator
Test Center
Technology and tradition
After its completion in early 1972,
the first machine to be tested in the
Muelheim generator test field was
a water-cooled 900 MW generator.
In the meantime, more than 450 generators of different type and power classes
from Siemens’ large portfolio of generators, ranging from 25 MVA to 370 MVA,
have been tested in accordance with
IEC 6034 and their distinctive specifications. After the center’s modernization in
2006, even the world’s largest generator,
SGen5-4000W, with a power output of
up to 2,235 MVA, can be type-tested here.
Today the Muelheim test field is one of
the most modern and powerful generator
test fields in Europe.
Why should a generator be tested?
In increasingly quality-oriented energy
markets, each and every power plant
component needs to be reliable and fully
functional. Testing a generator provides
an opportunity to prove that the function
and performance characteristics of the
generator are compliant with those stated
in the contract. The advantage is obvious:
higher availability. In addition a generator
test in Mülheim serves to prove the
machine’s functionality and verify
performance parameters and their
tolerance design (only for prototypes).

Testing the world’s largest generator, the SGen5-4000W
In accordance with IEC6034, the following
tests* can be carried out:
■■ Determination
of exact electromagnetic
performance parameters to secure
the generator’s ability to resist grid
disturbance conditions
■■ Determination of individual losses
and efficiency
■■ Determination of mechanical
and technical behavior
■■ Proof of scalability of the results of
type-tested generators to larger or
smaller models
■■ Proof of tightness under rotating conditions (for H2-cooled machines only)
■■ Proof of machine functionality and
verification of performance parameters
and of their tolerance design
(for prototypes only)
■■ At predefined witness points, the
customer can be present for some of
the tests performed on his generator
live in the control room
