• Ceiling voltage: 850V

1) > 50Hz / 60Hz for AVRs only.

UNITROL° 1000

AVR series for synchronous generators and motors with exciter machines. Microprocessor technology and IGBT output stage guarantee a wide application range.

Output current: up to 40ADC
Supply voltages: up to 300VDC or 250VAC (<400Hz)

MEGATROL combined solution

MEGATROL is a smart and compact solution, combining UNITROL° 6000 Static Excitation System (SES) and MEGADRIVE-LCI Static Frequency Converter (SFC) in one container.

The use of ABB's powerful AC 800PEC controller for both systems results in fewer costs for spare parts and training of maintenance staff for the customer. This is an attractive solution for gas turbine, combined cycle and pumped storage power plants applications.

MEGATROL medium range

The Megatrol medium range is typically used for gas turbines <200MW.

Max. starting power SFC: 5.5MW
Max. field current: 2,000A

MEGATROL power range

The Megatrol power range is typically used for gas turbines 200MW - 400MW.

Max. starting power SFC: 15.0MW
Max. field current: 6,000A

SYNCHROTACT° synchronizing equipment

The SYNCHROTACT 5 products are used for automatic and manual synchronization of generators with power networks and for paralleling of synchronous lines. Available types:

• SYN 5100 simple Synchrocheck
• SYN 5200 Synchrocheck with advanced functionality
• SYN 5201 automatic single-channel synchronizing device with frequency and voltage matching
• SYN 5202 automatic dual-channel synchronizing device with Synchrocheck in series as second channel
• SYN 5302 redundant automatic dual-channel synchronizing device

SYNCHROTACT CSS (Compact Synchronizing System) is a standardized, completely wired and tested solution for synchronization of synchronous generators with a network. As the key components it uses the proven and reliable SYNCHROTACT 5 devices. SYNCHROTACT CSS can be used for fully automatic as well as independent manual synchronization and therefore ensures higher availability of the power plant.

SYNCHROTACT° MSP

SYNCHROTACT° MSP (Modular Synchronizing Panel) is a customized synchronizing system built on a modular base. It is used to synchronize generators and to parallel lines. SYNCHROTACT° MSP includes:

• Synchronizing system using SYNCHROTACT° 5 devices
• Electrical measuring and metering system
