Our activity power generation provides for development, project planning, commissioning and maintenance of power generation equipment.

 

• Power generation sets with diesel and gas engines up to 55MVA

• Generators for power generation with gas and steam turbines

• Converters and inverters for the control of turbines and pumps of hydraulic power plants

• Uninterruptible power supply for information technology, industries and miscellaneous use

 

Since the foundation in 1887, AEG has built many power plants worldwide, driven by water, gas, coal or nuclear. In the year 1969, AEG and Siemens merged their power plant activities and founded KWU. AEG Industrial Engineering provides service for all AEG power plants. The following picture shows a machine hall with generator, turbine and high voltage pump motors delivered by AEG:

Power generation sets with diesel and gas engines

We design and deliver turnkey:

 

 

For control and surveillance we make use of our AEG Transinaut technology. Transinaut is a fully digital, programmable control with integrated protection for Diesel generators as well as gas motor/generator sets. Our Transinaut is is giving service in many plants for years, such as:

• Auxiliary power supply plants
• Combined heating plus generating plants
• Industrial power plants
• Emergency motor/generator sets

A brochure about our Transinaut system in pdf-format is available here (870 KB).

Generators for power generation with gas and steam turbines

The advantages of E – Pack:

• Reduction of interfaces decreases efforts and costs for engineering and construction.
• High total efficiency
• Low requirements in space for the system, since generator and gear unit are assembled without offset.
• No gear foundation, because the gear doesn’t have its own bearing.
• The delivery of a complete system reduces effort and time for assembly at construction site and results in shorter total delivery times.
• Generator and gear unit are piped already, only one connection each for oil supply and discharge is required.

Alternators, converters and excitation systems for use in hydro plants

For retrofitting and revamping in hydro power plants we project and deliver:

• Alternators

• Start up inverters for large hydro aggregates

• Digital excitation systems for alternators at new plants and modifications of existing rotating machines

• Converters and inverters for the continuous control of pump storage plants

 

Our activity UPS provides development, project planning, commissioning and maintenance of uninterruptible power supply equipment

• UPS for IT

• UPS for miscellaneous use

• UPS for industries

 

 

Rotating UPS / CPS  plants (Conditioned Power Supply)

The traditional UPS with static battery consists of a rectifier, battery and inverter. The UPS supplies energy in case of power failure for some time from the battery and passes only then the critical load to a diesel generator set for continuous supply. The UPS system needs much room and extensive cooling and the batteries have to be located in an air conditioned room in case of elevated temperatures. This is costly.
Our diesel-UPS-principle integrates traditional systems in a single concept with clear advantages. The diesel UPS consists of less components lowering the investment and increasing the availability remarkably. The rotating UPS needs less space due to this concept and saves weight. During normal service, the UPS system supplies clean current and works like a line filter. In case of failure of supply of the utility, the diesel starts without delay within a few seconds to rated speed. In between, the alternator together with the inertia and inductive coupling supplies the load. After that, the diesel motor and the alternator take over until the power returns.

Various systems can be operated in parallel in order to increase the power. We conceive the building containing all the systems and design them in a complete fashion including switchgear, exhausts and cooling system.

 

 

Gas turbines

We will care for a proper upkeeping of your gas turbines according to their actual status and their repair and maintenance. Erection, commissioning and measures to increase the output of turbines are also scopes of our program.

	Service for gas turbines Diagnosis and condition reports Checks / renewing of components Checks of nozzles, tests and renewals Inspection and repair in factory or at site Measures for increasing output Engineering of plants Checks and maintenance Complete service, independent from supplier Short operative outages Reliable availability Gas turbine test rack is available

We supply new industrial turbines, also as turbo genset up to 50 MVA. For large gas turbine power plants of 100-450 MVA we supply start-up inverters ( LCI ) and static thyristor exciters in compact cabinets. This equipment is also suitable for large hydro power plants. Our reference list contains contains several hundred units of this kind of equipment through the last decades. A description of a supplied solution can be found here.
