MEGATROL CS (Cross Start)

MEGATROL CS is a special application solution for multiple gas

turbine startups. Up to six generators with their related

excitation systems and three MEGADRIVE-LCI frequency

converters are connected together via Start-up Selection

Boards (SSB). MEGATROL CS is able to automatically control the

SSB isconnectors, select an available frequency converter for

start-up and support all required communication channels

during start-up. The selection of the MEGADRIVE-LCI can be

preconfigured manually.

Surprisingly compact solution

The merged functionality of MEGATROL enables a compact

mechanical design with the possibility to place the equipment

in one container. For gas turbine stations it is particularly

advantageous to get converter and excitation mounted and

cabled in a common container.

turbines and exciting the generator

Designing a drive system involves selecting and matching the motor and the

drive to satisfy requirements determined by the load, the supply system, the

ambient conditions and the process.

Open control system

ABB offers an open communication strategy, enabling

connection to higher-level process controllers. UNITROL 6800

and MEGADRIVE-LCI can be provided with all major fieldbus

adapters for smooth integration, monitoring and controlling of

different processes, according to customer requirements.

Key benefits

• One MEGADRIVE-LCI converter can start several generators

(Cross Start)

• Unlimited number of starts

• Encoderless control for high availability and reduced

maintenance costs

• Fuseless design for high reliability and less spare parts

• User-friendly Control Terminal

MEGADRIVE-LCI

Setting the standard

For more than 35 years ABB’s MEGADRIVE-LCI drives and static starters have

proven their maximum reliability and availability in a wide range of

industries and applications where high power and high voltage are required.

Gas turbine power plants have often to be started and run-up

quickly at short notice. The MEGADRIVE-LCI static frequency

converter uses the generator as motor to run it up to a certain

speed. For gas turbines, this is above the ignition speed from

where the turbine can accelerate the generator independently

up to rated speed and synchronize it to the power network.

ABB has more than 30 years of experience in the design and

manufacturing of static frequency converters, which became

the standard starting technology for heavy-duty gas turbines.

Power system stabilizer (PSS)

PSS can be an option to provide standard IEEE 421.5-2005

2A / 2B / 2C function. The PSS provision is nowadays included

in most grid codes. The PSS is used for effective damping of

power oscillations caused by the physical power grid.

Software and tool for the UNITROL 1000 product portfolio:

All UNITROL 1000 products are based on the same target

software source code, therefore equal performance can be

seen with UNITROL 1010/20 as well as with UNITROL 1005.

The same simulation models can be used for the entire

UNITROL 1000 product family, making UNITROL 1000

products suitable for very demanding grid code applications.

ABB provides several levels of service for:

• Single channel systems

• Dual channel systems

• Mounting on a plate or in a cubicle
