Introduction to the manual 27
Frame (size)
Refers to converter modules that share a similar mechanical construction, for
example:
• frame 5×R9iLC + 6×R9iLC includes five R9iLC generator-side converter
modules and six R9iLC grid-side converter modules.
Generator-side
converter
The converter part that is connected to the generator stator and controls the
generator operation. It converts the AC power from the generator to the
converter DC bus.
Grid-side converter
A converter that is connected to the grid and is capable of transferring energy
from the converter DC link to the grid and vice versa.
I/O
Input/Output
IGBT
Insulated gate bipolar transistor; a voltage-controlled semiconductor type widely
used in various converters because of their easy controllability and high
switching frequency.
Intermediate circuit
.
LCL filter
Inductor-capacitor-inductor filter at AC side of the grid-side converter.
Attenuates harmonics.
Main circuit breaker
Electrically-controlled main switching and protecting device. A withdrawable
breaker can also be used as the main disconnector.
MBC
Main breaker cubicle containing main switching and disconnecting devices,
power terminals, etc.
NETA-21
Remote monitoring tool
Parameter
User-adjustable operation instruction to the converter, or signal measured or
calculated by the converter.
PE
Protective Earth
PLC
Programmable logic controller
PSL

Wind turbine converter
A converter for controlling AC generators in wind turbine applications.
Wind turbine system
Wind turbine system consists of the wind turbine, wind turbine converter,
generator etc.
WTC
Wind turbine controller. The wind turbine controller controls the whole wind
turbine system.
ZMU
Memory unit attached to the BCU control unit connector X205 MEMORY UNIT.
