We have developed our three flexible packages based on

our proven SGT5-4000F gas turbine and equipped them

specifically for the 50 Hz market. All of the packages

feature outstanding energy efficiency values, whether

it’s the SGT5-PAC 4000F for a gas turbine power plant or

the SCC5-PAC 4000F version for combined cycle power

plants. And the outstanding efficiency values can be

attributed to more than just the use of the gas turbine:

The other components in our packages combine the

highest level of quality and outstanding performance

data. Both the specified SGen5-1200A and SGen5-2000H

generators as well as the SST5-3000 and SST5-5000

steam turbines are precisely tailored to fit the gas turbine’s

parameters to achieve optimal energy efficiency throughout

the entire power generation process.

This allows you to leverage the full potential of your

plant when operating at a full load as well as during

flexible operation under a partial load. The result is

lower emissions, reduced fuel consumption, and lower

costs.

All interfaces under control

The key advantage of our SGT5-PAC 4000F and

SCC5-PAC 4000F packages is that all the elements work

together seamlessly. This holds true both within the

packages and for the connection of other technologies.

Strong machine at the core

The centerpiece of our SGT5-PAC 4000F / SCC5-PAC 4000F

packages is the gas turbine. Its performance profile has

a single objective: your success in the competitive power

markets. That is why our development consistently

focuses on maximum efficiency, performance, and flexi-

bility – while achieving outstanding low emission values

during partial and full-load operation. Our turbine also

offers these features in our reliable high-availability

packages. The decisive benefit for you, however, is that

we are never content to rest on our laurels: We continually

work to further improve this proven machine – enhance-

ments that can be implemented in retrofits.

Built to give you an edge

The SGT5-4000F is rightly considered to be a powerful

workhorse among Siemens gas turbines. It was

developed to provide its operators with competitive

advantages in fiercely competitive markets – with its

proven design, its robust structure, and a range of

special features including its construction with:

•Two rotor bearings

•Generator drive on the cold end

•Disk-type rotor with Hirth serrations and a central

tie bolt

The SGT5-4000F offers convincing performance, thanks

to its very smooth operation, low thermal loads under all

operating conditions, and superior mechanical stability.

It features an outstanding cold start and warm start

capability with absolute reliability – a fundamental

requirement for flexible operation. The gas turbine is

intrinsically optimized for use in a simple cycle power

plant as well as in combined cycle operation. As an oper-

ator, you thus benefit from additional flexibility, because

you can quickly commence operations with a simple

gas turbine power plant and with the assurance that

you can subsequently retrofit to combined cycle opera-

tion if your requirement profile changes. Of course,

our service department is at your disposal from day

one after delivery and commissioning of your turbine

packages.

Peak values for energy efficiency

The SGT5-4000F was developed specifically for competi-

tive markets in which every percentage point is crucial

when it comes to energy efficiency. With this in mind,

we have been able to significantly increase the energy

efficiency of the gas turbine in a number of stages since

its introduction in 1996. Over the years, the turbine

capacity has increased from 240 MW to a current level

of 329 MW. The majority of turbines can be retrofitted

with the technical adaptations necessary to achieve the

new capacity level.

Flexible for gas and oil operation

With its flashback-free hybrid burner, the SGT5-4000F

can operate using natural gas as well as oil. This feature

enables you to leverage fuel price differences to work

more profitably without the need to invest in additional

technology. What is special about our turbine is that

you can seamlessly switch between gas and oil during

operation (online switchover).

Low investment costs per kilowatt

The SGT5-4000F pays for itself quickly. This can be

attributed to its relatively low investment costs and to

the fact that the machine does more thanks to its high

energy efficiency. Combined with the high-performance

generators from Siemens, it produces more power that

can be marketed at a profit. In addition, the turbine can

flexibly cover peak loads as well as base load and partial-

load operation – while achieving outstanding performance

values and producing very low emissions.

Economical design

The low operating costs of the SGT5-4000F are a result

of its high energy efficiency. In addition, it has a highly

maintenance-friendly design and, thanks to intelligent

features, helps to prolong maintenance intervals and

minimize maintenance-related operation interruptions.

Features include the annular combustion chamber in

which the heat shield tiles can be individually replaced

as needed, and details such as the uniform temperature

distribution with combustion that remains stable over

the lifetime of the turbine, and the internal cool air

extraction designed to cool the components exposed

to high temperatures. They provide for low lifecycle

costs and many years of reliable operation.

With almost 1,000 large steam turbines and approxi-

mately 380 GW capacity, technology from Siemens is

responsible for almost 17 percent of the power plants

installed worldwide. For the SCC5-PAC 4000F combined

cycle power plant (CCPP) packages, the features and

performance of the type SST5-5000 and SST5-3000 steam

turbines are individually adapted to achieve an optimal

focus on your goals as an operator.

SST5-3000 and SST5-5000 –

the versatile steam turbines

While the SST5-3000 features a separate high-pressure

cylinder and a combined intermediate-pressure / low-pressure

cylinder with a single-flow axial exhaust, the SST5-5000

features a combined high-pressure / medium-pressure

cylinder and a double-flow low-pressure cylinder. Both

steam turbines are highly compact and perfect for use

in combined cycle power plants with the state-of-the-art

gas turbine technology offered by the SGT5-4000F. The

SST5-3000 covers a power range of 90 to 250 MW, while

the SST5-5000 operates in a power range between 120

and 650 MW. To meet your specific requirements, the

turbine sections are assembled individually and the blade

path is optimized. During this process, the adaptation of

prefabricated modules helps to accelerate the assembly

work and commissioning on-site while minimizing the tech-

nical risks. The success can be seen in a failure rate that is

50 percent less than the average value reported by the North

American Electric Reliability Council (NERC). In addition,

the overhaul intervals are synchronized for the gas turbine,

generator, and steam turbine to minimize scheduled plant

downtimes and achieve optimal plant availability.

The selection of a generator is essentially based on the

performance of the power plant – in gas turbine operation

or in highly efficient combined cycle operation. Over a

century of experience in building generators of all kinds

has gone into the development of our highly specialized

generators for package applications in combination with

the SGT5-4000F.

Reliable performance: SGen5-1200A

Depending on the requirement profile, the air-cooled

generators of this series are available with either TEWAC

(Totally Enclosed Water-to-Air Cooling) or OAC (Open Air

Cooling) cooling systems.

With a capacity of up to 370 MVA, they can be used

in areas until now reserved for hydrogen-cooled units.

Their high energy efficiency of 98.8 percent and their

high reliability and availability values make them the

first choice for all operating modes, from base loads to

peak load coverage, for use in gas turbine power plants

and in combined cycle power plants. These generators

feature a highly maintenance-friendly design and the

maintenance intervals can easily be coordinated to

coincide with turbine maintenance. They offer optimal

performance while minimizing lifecycle costs.

For maximum performance: SGen5-2000H

With an output range from 350 MVA to 600 MVA and

efficiency levels as high as 99 percent, the hydrogen-

cooled SGen5-2000H seamlessly connects to the air-cooled

SGen5-1200A. Similarly, thanks to global vacuum pressure

impregnation, the SGen5-2000H offers high availability

combined with low technical risk. Its flexible use in all

performance classes is made possible through a variety of

features, including Omega™ coolers which ensure an even

temperature distribution in the generator, while the carbon

seals combine minimal oil use with outstanding emergency

running properties. The generator design has proven itself

worldwide in numerous reference applications.

SGen5-1200A and SGen5-2000H:

the reliable powerhouses

11

Auxiliary components –

the ideal way to round out your package

In our packages, every detail has to be just right, because we not

only supply perfectly coordinated core components, but the auxiliary

components also need to ensure reliable and economical operation.

That includes customized, maintenance-friendly design and piping

that is adapted to the use and easy to install.

12

Air intake system

The air intake system comprises filter housing, filter system,

and inlet duct work. The filter housing offers weather pro-

tection and prevents large debris from entering the filter

system. The filter system removes both large particles and

fine particulates from the air stream. The inlet air duct

directs the air flow into the gas turbine compressor inlet

manifold.

Exhaust gas system

After expanding through the combustion turbine, the

gases pass through the exhaust gas diffuser, which

provides connection to a stack, a heat-recovery steam

generator, or a diverter and bypass stack.

Condenser system

The condenser collects and condenses exhaust steam

from the low-pressure turbine and steam from the turbine

startup bypass stations. It also accepts condensate from

locations such as drains, vents, and steam seals. It further

produces and maintains a high vacuum at the low-pressure

turbine exhaust.

Control system

The control system is based on Siemens Power Plant

Automation SPPA-T3000 and contains control, monitoring,

and protection equipment necessary for the turbine and

generator. This includes the operation and monitoring

system, the automation system, and the interface to the

plant control system.

Electrical systems

The electrical systems supply low- voltage power to the

package loads and include battery and battery charger for

uninterruptible direct current power supply. The electrical

equipment also includes static exci tation equipment with

transformer, starting frequency converter with transformer

for static startup of the gas turbine via the generator, and

generator protection and synchronization equipment.

Power Control Centers (PCC)

Prefabricated and functional precommissioned PCC

containers provide compact and weather-protected

accommodation of electrical and I&C equipment.

Redundant HVAC units also offer a controlled environ-

ment for sensitive equipment.

Enclosures

Enclosures provide noise abatement for personnel.

They also provide the means for delineation of hazardous

areas and containment of fire suppression agents.

Fire protection

Fire protection includes fire detection and fire fighting

and is provided for gas turbine, fuel gas system, and PCCs.
