SPPA-E3000 Brushless Excitation Systems
Brushless Excitation Systems (BES); Type RG3 /
THYRISIEM®
are excitation systems for generators with
(brushless) exciters, using cutting-edge
technology. They are suitable for all
performance classes from 1 to more than
1000 MVA in gas, hydroelectric and steam
power plants, and are characterized
by absolute reliability and optimum efficiency.
Your Benefits
■ Highest possible availability
and reliability due to robust
and tried-and-tested
technology
■ Minimum conversion time
courtesy of "Plug out – Plug
in" replacement of the old
excitation system
■ Low maintenance costs
through the use of proven
industry components
and modular structure
■ Ultra-simple and thus faultfree operation due to
transparent representation
of operating status
The Task
Sooner or later, the existing excitation
system will reach the end of its service life.
This may be because some modules have
been discontinued, or simply because
they can no longer operate economically.
This is the case if, for example, spare parts
costs have become prohibitive, or grid operators
impose new requirements for control dynamics
which the systems are unable to meet,
or for some other reason the statistical
risk of failures exceeds an acceptable level.
What is then required is a solution that perfectly
fits the existing situation and ensures reliable,
continuous, operation based on innovative
technology.
which power supply is present, which I&C
system you employ or whether the I&C
facilities are being replaced at the same time.
Another particularly important point: Regardless of which redundancy concept is required,
Siemens will implement a customized concept,
covering everything up to comprehensive fullredundancy concepts. This flexibility is realized
exclusively on the basis of industry-standard
components; no "tailor-made“ elements or
costly spare part holdings are involved.
The switchover to the latest generation of
SPPA-E3000 BES also benefits user friendliness,
due to ergonomic and transparent presentation
of the operating status and excellent interaction
with the generator protection and I&C systems.
Of course Siemens ensures smooth
replacement, encompassing everything from
project planning through to commissioning,
and then provides ongoing service support
for BES. The "Plug out – Plug in" replacement
of the excitation system requires minimal
conversion time.
The BES excitation system adapts to the framework conditions
within your power plant. Shown here is an example of a BES
Type RG3.
Our Solution
BES is a tried-and-tested solution for all
generators with exciters. For many years
now, more than 750 systems have been
demonstrating the highest levels of reliability
and robustness.
The solution can be adapted to conditions
in each individual power plant due to the
high degree of flexibility of the supply concepts.
The excitation system is not dependent on
which generator you choose to employ,
