Description
Auxiliary control unit. Contains control electronics, auxiliary voltage circuitry, etc.
Auxiliary measurement unit
Type of control board
Type of control unit
The part in which the control program runs.
Converts direct current and voltage to alternating current and voltage, or vice versa.
Grid-side converter or generator-side converter module
One section of a cabinet-installed wind turbine converter. A cubicle is typically behind
a door of its own.
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 circuit between grid-side converter and generator-side converter
Energy storage which stabilizes the intermediate circuit DC voltage
Dissipates the surplus energy conducted by the DC chopper to heat. Essential part
of the DC chopper circuit.
Distributed drives communication system protocol
Direct torque control, a generator control method

Physical size of the converter module, for example R9iLC.
The part of a wind turbine converter that is connected to the generator stator and
transfers the generator-produced AC power to the converter DC bus
The part of a wind turbine converter that transfers energy from the converter DC bus
to the AC grid and vice versa
Insulated gate bipolar transistor
Inductor-capacitor-inductor filter
Remote monitoring tool
In the control program, a user-adjustable operation instruction to the converter, or
signal measured or calculated by the converter.
Protective earth (ground)
Programmable logic controller
Power stage link
I/O module. Subtypes of this module are CI581-CN, AX522, and AI523.
Uninterruptible power supply
Converter between a wind turbine generator and the grid
Wind turbine system consists of the wind turbine, wind turbine converter, generator
etc.
Wind turbine controller. Controls the whole wind turbine system.
Type of memory unit, attached to the control unit
