2.
Run the cables through the Ingecon
cable terminals to the central terminal as shown in the following figure.
3.
Check that the cable terminals have been tightened correctly at the connector terminals.
4.
Tighten the cable glands to ensure that the equipment is airtight.
It is essential to ensure that the connection polarity is correct. Given the fact that, an incorrect
connection will cause the equipment to malfunction
5.3.7. Connection of the braking resistors
The purpose of the resistors is to limit the power and perform the wind turbine emergency stop. The resistors must be
sized according to the wind turbine characteristics (power and output voltage).
The power delivered by the wind turbine is governed by the following equation:
where:
P: power
k: constant
Cp: wind turbine aerodynamic performance coefficient
V: wind speed
Analysing the equation above, it should be emphasised that, for high wind speeds, if there is no mechanical braking
or auto-braking system, then high powers will be generated.
It is important to bear in mind that, for wind turbines with no mechanical speed limitation system, the resistors are
the only way of braking the wind turbine.
