Common mode voltage impact on wind turbine main shaft bearing

, 2021
Main shaft bearing is a critical component in the wind turbine rotating system. But the bearing voltage, which is generated by the potential differences between the bearing and the main shaft, often causes the downtime of the main shaft bearing.

Low-Voltage Ride Through Capability Analysis of a Reduced-Size DFIG Excitation Utilized in Split-Shaft Wind Turbines

Journal of Low Power Electronics and Applications
Split-shaft wind turbines decouple the turbine’s shaft from the generator’s shaft, enabling several modifications in the drivetrain. One of the significant achievements of a split-shaft drivetrain is the reduction in size of the excitation circuit.

A Cancellation-Based Circuit for Reducing Both the Shaft Voltage and CM Noise in Motor Drive Systems

In motor drive systems, the common-mode (CM) voltage of the inverter introduces negative impacts such as the shaft voltage and CM noise. The shaft voltage generates bearing current and may reduce the lifetime of bearings, while the CM noise may interfere
