As the rated capacity of the Direct-Drive Permanent Magnet Wind Generator (DDPMWG) increases, the heat produced from the generator’s inner components also increases and it becomes difficult.

When the active power increases, the SD of the main bearing temperature rise gradually decreases. The variation pattern of the SD of the temperature rise of the generator stator is more complicated. There appears to be a positive correlation when the active power is between 0 and 1300 kW and a negative correlation when it continues to rise.

The temperature of wind does not directly affect the functioning of a wind power generator. Wind power is generated by the movement of air, not the temperature of the air. However, extreme temperatures can potentially impact the durability and efficiency of the generator's components over time.

The relevant factors influencing the temperature signals of WTs are roughly divided into three categories: (1) external environment: ambient temperature, wind speed, humidity, atmospheric pressure, and so on; (2) operating condition: WT output power, rotor speed, pitch status, yawing status, and so on; and (3) health condition: the dynamic .

It is shown that the system operating point slides on the set control trajectory as the generator temperature rises. The potential to counteract the effect through the use of temperature-matched control characteristics is investigated through a simulation study.

6 FAQs about [Generator wind temperature rises by 1 degree and decreases]

Does wind speed affect power generation?

Many research studies illustrate the influence of wind speed on the turbine at a flat terrain site. The results show that wind turbines heavily depend upon atmospheric conditions, and consequently, power generation increases with the increase in the wind speed at the hub height .

How does a wind turbine affect power generation?

The performance of a wind turbine is prone to the aerodynamics of the blade. Furthermore, a collision of birds and insects alters the aerodynamic shape of the blade, and this leads to an increase in aerodynamic drag, as a result, power generation is decreased by up to 50% .

Do wind turbine generators increase power ratings?

The main focus of wind energy related industries is to identity efficient yet reliable solutions to lower the cost of energy conversions . In recent years, the advancements and enhancements of wind turbine generators managed to increase the power ratings . However, there are a few points to look out for.

What factors affect wind energy generation?

Among them, the performance of wind turbines has a major influence on wind energy generation. Several factors affect the performance of a wind turbine, including operating wind speed, blade length, tower height, casing design, and surrounding environmental factors such as weathering, icing, and birds and insect collisions .

Why should a wind turbine be higher than 10 m?

Furthermore, increasing the height of the tower will enable the turbine to receive high wind speed. Moreover, wind speed and power can increase by 20% and 30%, respectively, with increasing the tower height of 10 m. Under extreme wind conditions, the wind turbine rotates extremely fast, which can damage the turbine [76, 77].

How does air density affect wind power?

In the Northern Hemisphere, although changes in air density and wind speed are smaller, the variation in wind power density can be higher, mainly due to air density instead of wind speed. However, this effect is low in tropical locations. The aspect ratio is more important in the power yield of the turbine.
