Protecting turbines from high-frequency voltage

High-frequency voltage can be destructive to a turbine’s bearings, but technology exists to properly ground it before it can inflict any damage.

The generator within a wind turbine is capable of producing up to 5 MW of electricity. An unfortunate side effect of that is that voltage can build up within the generator itself. That voltage naturally runs to ground, but along that path, the voltage arcs through the bearings within the generator’s rotor. This constant discharge […]

Applications of magnets in wind turbines

Magnets are being used to lower costs, improve reliability, and increase maintenance intervals in many wind farms around the world.

Permanent magnets play a critical role in some of the world’s largest wind turbines. Rare earth magnets, such as powerful neodymium-iron-boron magnets, have been used in some wind-turbine designs to lower costs, improve reliability, and reduce the need for expensive and ongoing maintenance. Wind turbine generators In 1831, Michael Faraday created the first electromagnetic generator. […]

Wind turbine control methods

Exploring the fundamental concepts and control methods/techniques
for wind-turbine control systems.

Wind-turbine control is necessary to ensure low maintenance costs and efficient performance. The control system also guarantees safe operation, optimizes power output, and ensures long structural life. Turbine rotational speed and the generator speed are two key areas that you must control for power limitation and optimization. The “Control Methods” and “Control Strategies” sections of […]
