6 FAQs about [Generator response to wind changes]

Does a large generator loss affect power system frequency response?

This paper provides an updated review of the literature on the power system frequency response due to a large generator loss with the increasing penetrations of wind and PV generations.

How does wind speed affect generator power?

Increasing the wind speed resulted in an increase in the torque of the generator, that is, an increase in the generated power. The diagram in Figure 10 shows how increased generated power is transmitted to the grid. An increase in generator power increases the rectifier current iisp that supply the DC bus.

What is the frequency response to a large generator trip?

The frequency response could be described as instantaneous frequency deviations from the nominal system frequency. This paper aims to discuss the frequency deviations in response to a large generator trip (Fig. 1). Table 1. Global Wind Generation Outlook.

Does increasing penetration of wind/PV generation affect frequency response?

Therefore, frequency response investigations warrant significant attention of academia and industries in investigating the impacts of increasing penetrations of wind/PV generation on the system frequency. The frequency response could be described as instantaneous frequency deviations from the nominal system frequency.

What happens if a wind turbine is switched to a new characteristic?

When switching to a new characteristic, the power factor of the turbine Cp = Pout/Pin is no longer at the optimum point as can be seen from the equation (1), therefore the WT power is no longer maximal for this new wind speed ( Maxime, 2000 ).

What is the power factor of a wind turbine after transient process?

This is confirmed by the simulation, where after the transient process the wind turbine power factor value is again at the maximum, Cp = 0.465 ( Figure 8 ). One of the goals of the regulation was the realization of vector control of the asynchronous generator.
