Such a system will allow timely detection of deterioration of wind turbine components and inform the operator, located anywhere in the world, provided he has an Internet connection, of the need to replace or repair a certain component of the wind turbine. This will reduce the downtime of wind...
In particular, lightning damages to main-shaft bearings can result in high costs of maintenance, due to the inherent burden in the replacement of these components. The paper focuses on the modeling of wind-turbine main-shaft bearings. Two models are presented and experimentally validated: one ...
The invention describes a wind turbine main bearing (1) realized to bear a shaft (13) of a wind turbine (10), which shaft is caused to rotate by a number of blades (11) connected to the shaft (13), characterized in that the wind turbine main bearing (1) comprises a fluid bearing ...
Multilayer perceptron has been employed for modelling the fault-free behaviour of WT components. The prognostic module used particle filter technique to determine the main bearing RUL. Results showed a strong indication of failure within a 30-day window. Bechhoefer and Schlanbusch [51] used a ...

If flux components exist at these frequencies they are usually small, but they appear in undiminished proportion as harmonics in the e.m.f. For example, for q = 3 n13579111315171921kdn0.9660.6670.2170.1170.3330.1770.2170.6670.9600.9600.667 kpn is less than kp1 for most slot numbers and coil ...
The main components of the seal are made of PTFE, which means that they are ozone resistant, slow to age, and chemically resistant to additive oils – all of which are relevant for wind turbine gears. This, along with a non-contact operation in wind turbine gears, means the service life...
The control and electrical system models simulate the controller logic, sensors, and actuators of the blade-pitch, generator-torque, nacelle-yaw, and other control devices, as well as the generator and power-converter components of the electrical drive. The structural-dynamics models apply the ...
as well as the generator and power-converter components of the electrical drive. The structural-dynamics models apply the control and electrical system reactions, apply the aerodynamic and hydrodynamic loads, adds gravitational loads, and simulate the elasticity of the rotor, drivetrain, and support st...
We are specialized in manufacturing different type of large mechanical products according to engineer drawings.The products include gears, pinions, sprockets, shafts, wheels, rollers, couplings, pulleys, housings ,frames, molds, nonstandard machinery parts, wear resistant p...
