1.2.4. Ingecon® μWind Interface (IWI)
As explained in the previous point, it is necessary in some circumstances to provide an external braking system and/
or an AC-DC conversion system. To fulfill this need, Ingeteam has included the Ingecon
®
μWind Interface unit in its
range of products.
The Ingecon ® μWind Interface unit was designed to work in conjunction with Ingecon ® μ
W
ind converters in the control
and conversion of energy generated by the wind turbine.
The purpose of this unit is to perform the following functions:
• Convert from AC to DC, changing the AC voltage generated by the wind generator to DC for the Ingecon
®
μ W ind unit.
• Protect the system from excess rotational speed and overvoltage, as well as limiting power capture when the
generator is working in high wind speeds.
• Shut down the wind generator.
• Remotely control the installation and monitor additional variables of the wind power installation.
With its ability to convert AC to DC, the Ingecon
®
μWind Interface allows wind generators with a DC output to be
connected too. In this case the protection, monitoring and remote control functions will still be utilised.

The braking resistors must be dimensioned as explained in the Ingecon ® μWind Interface
(AAY2000IKI06) manual. Should this point not be complied with, Ingeteam will not guarantee the
ability of the generator to brake and/or stop.

1.2.5. Compositions
At the hardware level, there are small variations between units for different countries.
However, although these differences are small, not all units can be configured to the options of every
country. Refer to the configuration section for further information.
