Operating wind power stations with high availability

Wind turbines are complex systems that are exposed to high loads. Keeping an eye on electrical safety is crucial to avoid failures, maximise efficiency and safeguard both personnel and the installation itself.

Electromagnetic faults

The complex electronics within a wind turbine are sensitive to electromagnetic interference (Fault), which can be caused by various factors. These include lightning strikes, but also the wind turbine itself or external sources. These faults can affect the control systems and subsequently lead to malfunctions.

Different earthing concepts within the wind turbine

There are various earthing systems within a wind turbine whose interaction plays an important role. Errors in the earthing can lead to dangerous potential differences, which significantly increases the risk of electric shocks and system failures.

Extreme weather conditions

Due to their exposed location, wind turbines are exposed to extreme weather conditions such as strong winds, rain, ice and snow. These impair electrical safety if they lead to a deterioration in the deelectric properties of materials or physical damage to the installation.

Shielding measures

Shielding measures consisting of metal enclosures and shielded cables are implemented to reduce electromagnetic faults. These measures serve to safeguard the control systems and electronics of the installation from external and internal sources of interference.

Insulation and residual current monitoring

The use of insulation monitoring devices (IMDs) and residual current monitoring (RCM) enables the early detection of errors. These systems continuously monitor the insulation and residual current in the installation so that anomalies can be identified immediately and appropriate countermeasures can be initiated.
