26 Introduction to the manual
Terms and abbreviations
Term/abbreviation
Explanation
Auxiliary voltage switch
Main switch for the auxiliary voltage
Auxiliary control cubicle
(ACU)
The cubicle with auxiliary devices such as auxiliary voltage circuit breakers,
control electronics, measurement boards, etc.
BAMU
Main voltage measurement board
BCON
Type of control board
BCU
Type of control unit, a BCON board in a metal housing. See
DC chopper
Protects the converter by cutting down a peak overvoltage in the converter DC
link: conducts the surplus energy from the intermediate circuit of the wind
turbine converter to the DC resistor when necessary. The chopper operates
when the DC link voltage exceeds a maximum limit. A sudden disturbance in
turbine operation or grid can cause the DC voltage rise.
DC resistor
Dissipates the surplus energy conducted by the DC chopper to heat. Essential
part of the chopper circuit. See
CCU
Control cubicle
Control board
Circuit board in which the control program runs. See
Control unit
Control board built in a rail-mountable housing. See
Converter
Converts direct current and voltage to alternating current and voltage, or vice
versa.
Converter module
Grid-side converter or generator-side converter module
Cubicle
One section of a cabinet-installed wind turbine converter. A cubicle is typically
behind a door of its own.
DC link
DC circuit between grid-side converter and generator-side converter
DC link capacitors
Energy storage which stabilizes the intermediate circuit DC voltage.
DDCS
Distributed drives communication system; a protocol used in optical fiber
communication
DTC
Direct torque control; a generator control method by ABB.
EMC
Electromagnetic compatibility
FCAN
Optional CANopen® adapter module
FCNA
Optional ControlNet™ adapter module
FDNA
Optional DeviceNet™ adapter module
FEA
Optional extension adapter module
FECA
Optional EtherCAT® adapter module

Optional Ethernet adapter module for EtherNet/IP™, Modbus TCP® and
PROFINET IO® protocols
FIO-01
Optional digital I/O extension module
FIO-11
Optional analog I/O extension module
FPBA
Optional PROFIBUS DP® adapter module
