Resonance frequency of wind power in solar container communication stations

4 FAQs about Resonance frequency of wind power in solar container communication stations

Does a wind farm have a high-frequency resonance frequency?

Then, the variation law of high-frequency resonance frequency of the power grid of the wind farm with cable parameters, the number of chain circuits in the field, the number of wind turbine units, and the power grid impedance are studied, and the risk of high-frequency resonance in the power grid of the wind farm is evaluated.

Does high-frequency resonance occur in wind and PV power systems?

High-frequency resonance has also been observed in wind and PV power systems, although there has been no public report to our knowledge. Typically, this type of resonance is at lower frequencies than those found in MMC-based HVDC systems due to the relatively longer delay in large turbine converters.

Why does a wind turbine have a high frequency resonance?

Because of its relatively low frequency, such a resonance may be easily confused with steady-state harmonics and mislead the investigation of its root cause . The capacitive impedance also makes it possible for a wind turbine to develop high-frequency resonance with other turbines.

What is the resonance between wind turbines and HVDC converter stations?

In addition to the ∼400 Hz resonance between wind turbines and the offshore HVDC converter station described in, harmonics due to higher-frequency resonances, some reaching 3–4 kHz, have also been measured in both offshore and onshore HVDC converter stations.
