Generator wind temperature operation

Can condition monitoring reduce the maintenance cost of a wind turbine?

Abstract: Condition monitoring can greatly reduce the maintenance cost for a wind turbine. In this paper, a new condition-monitoring method based on the nonlinear state estimate technique for a wind turbine generator is proposed. The technique is used to construct the normal behavior model of the electrical generator temperature.

What is the thermal performance of bladeless wind power generator?

The thermal performance of the bladeless wind power generator will determine the power rating of the machine in the application of wind power generation system. In particular, it is imperative to well understand and control the thermal behavior of the generator in structure without blade of wind energy conversion system.

Should a generator be connected to a wind turbine?

One major design decision is whether to directly connect the generator’s shaft to the wind turbine or to use a gearbox [ 10, 11, 12, 13, 14, 15, 16 ]. Both designs have pros and cons. The gearbox option allows the generator to operate at a higher speed than the one provided by the wind turbine blades.

Which generator is best for a wind turbine?

Small wind turbine applications are therefore better using a gearbox or an oversized direct-drive generator that can be naturally cooled. The direct-drive generator is therefore more suitable for medium to large wind turbines.

How can wind turbines be cooled?

For example, the industry standard for cooling offshore large wind turbines adopted by many OEMs is forced air cooling in a closed loop configuration. This solution is bulky and furthermore increases in size and weight with the wind turbine output power.

How much power does a wind turbine use?

At the core of the wind turbine is the electrical generator, usually associated with power electronics. The generator’s power rating can range from a few kW [ 8, 9] (supplying a single household, sometimes in conjunction with solar or batteries or backed up by the grid) to tens of megawatts supplying tens of thousands of homes.
