Siemens Gas Turbine Packages –

Serving Your Project Needs

Siemens supplies standardized and pre-

engineered gas turbine packages custom-

ized to match specific project needs in

the form of simple cycle gas turbine power

plants and combined cycle power plants.

The standard Siemens Gas Turbine Package

(SGT-PAC) combines the essential mechan-

ical, electrical, and control equipment to

serve a variety of project scopes effectively.

The SGT5-PAC 4000F is a key package

for 50 Hz markets. The vital component

is our advanced Siemens gas turbine

SGT5-4000F.

A Siemens Gas Turbine Package is:

A cost-effective power generating

system with pre-engineered and stan-

dardized design and base scope of

supply, with interconnecting piping

and wiring pre-assembled to a large

degree.

Flexible in design and scope thanks

to pre-engineered options to meet

project- and site-specific conditions,

capable of increasing the operating

flexibility and performance of an

existing power generating system.

These options can replace or add

systems to the base scope.

Focused on the core equipment of a

self-contained power generating system

for power plants with gas turbines, it

consists of gas turbine and electrical

generator as well as all the systems

required for the safe and reliable oper-

ation of these components: air intake

system, exhaust gas system, electrical

systems, instrumentation and control,

generator excitation system, start-up

system, and such major auxiliaries

as the fuel system and lube oil system.

The development of this package stems

from the requirements of the utility

industry for low initial cost and a rapid

and reliable on-line generation system.

It is equally well-suited to meet the

requirements of industrial users. Heat

recovery applications include combined

cycle, repowering, and cogeneration

in a wide range of environments and

requirements.

Design Features and Arrangement

The design of the Siemens Gas Turbine

Package represents over 50 years of

experience in gas turbine technology

and power plant design, resulting in a

reliable self-contained electric power

generating system.

The SGT5-PAC 4000F scope of supply

represents the core equipment for a

power plant equipped with gas turbines:

Gas turbine

Electrical generator

Air intake system

Exhaust gas system

Start-up system

Major auxiliary system

Instrumentation and control

Electrical systems

Power control center

Enclosures

Fire protection

Generator systems

To minimize field assembly and the need

for piping fabrication during construction,

Siemens utilizes a packaging and piping

concept whenever possible. Moreover,

subsystems have been grouped and in-

stalled in auxiliary packages.
