About How to adjust the generator wind temperature
Allowed bearing temperature rise limits should be determined by NDE bearing temperature. DFIG (Doubly fed induction generator) and SCIG (Squirrel cage induction generator) are the two most commonly used generators for the onshore geared wind turbine. This paper discusses the issue with IC6A1A6 air to air-cooled SCIG.

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 this article explain which techniques to use and how to manage these areas. WIND TURBINE OPERATION A wind turbine is a revolving machine that converts the.
This paper aims to overview the cooling techniques in direct-drive generators for wind power application, based on generator size, reliability and maintenance requirements. It is organized as follows.
And the temperature cooling range can be controlled by adjusting the flow rate of the coolant in the cooling circuit, which provides cooling guarantee for the high temperature of the permanent magnet wind turbine under various conditions.
Special literature recommends that air gap length δ to be equal or bigger than 0.001 ·D a [3, 10]. In our case, δ ≥ 0.5 mm. At the same time, to decrease the influence of armature reaction, permanent magnet losses and their excessive heating, air gap length should be increased.

6 FAQs about [How to adjust the generator wind temperature]
Does ambient temperature affect the cooling of a permanent magnet wind turbine?
Taking a 2.5 MW PMSG permanent magnet wind turbine as an example, four kinds of ambient temperature were selected to be tested when the generator was full of power. It is revealed that the ambient temperature has a great influence on the cooling of the generator.
How do you control a wind turbine?
imize or limit power output. You can control a turbine by con-trolling the generator speed, blade angle adjustment, and rotatio of the entire wind turbine. Blade angle adjustment and turbine rotation are also known as pitch an yaw con-trol, respectively. A visual representation of pitch and yaw adjustment
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.
How hot does a wind turbine get?
As stated prior, due to the wind turbine locations they are subjected to extreme temperatures swings, typically from -30ºC (-22ºF) to 55ºC (131ºF). All of the electronic equipment and circuits installed in the turbine must be designed to operate reliably over the entire temperature range.
What is the third requirement for wind turbine rotor – generator?
The third requirement relates only to wind turbines and corresponds to the global trend of abandoning the scheme “wind turbine – gear – generator” in favor of the scheme “turbine rotor – generator”, i.e., using generators with low rotational speed directly coupled to the turbine directly.
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.
