6 FAQs about [How to divide the wind zone of the 300mw generator rotor]

What is a field winding rotor?

To understand the intricacies of the field wind-ing design, it must be remembered that the basic function of the rotor is to produce a mag-netic field of the size and shape necessary to induce the desired output voltage in the stator. The rotor can be visualized as a large rotating electromagnet with north and south poles.

What are the three methods of wind turbine rotor design?

There are mainly three aerodynamic methods for wind turbine rotor design to analyze the blade thrust force: Blade Element Momentum (BEM), Computational Fluid Dynamics (CFD), and Vortex-based model. ... ... There were many attempts to increase the efficiency of the power generation turbine such as wind turbines .

Do wind turbines use horizontal axis rotors?

The review provides a complete picture of wind turbine blade design and shows the dominance of modern turbines almost exclusive use of horizontal axis rotors. The aerodynamic design principles for a modern wind turbine blade are detailed, including blade plan shape/quantity, aerofoil selection and optimal attack angles.

What factors affect a generator rotor?

There are a number of other concerns that also affect generator rotors. Thermal sensitivity is the term used to describe an excessive vibration of the generator rotor, induced by the heating effect of the field cur-rent. As field current flows in the winding, the copper heats up. Two things happen as a con-sequence:

What is the difference between a two-pole rotor and a four-pole winding?

Four-pole rotor windings are subject to much less duty than those with two-pole designs. The four-pole rotor turns at half the speed, so the centrifugal loading of the copper winding against the wedges and retaining rings is con-siderably reduced.

Can a direct cooled rotor uprate a gas turbine?

The same applies to a direct-cooled con-version or a replacement rotor with perhaps more uprate capability. It has been common to support a gas turbine or steam turbine uprate by taking advantage of the existing generator margin (i.e., just operate the generator at a higher power factor than origi-nally designed).
