6 FAQs about [Wind-gathering and speed-increasing wind power generation device]

How does wind speed affect the output power of a speed regulating generator?

The outer rotor speed nout of the speed-regulating generator increases from zero with the rise of wind speed v since the wind speed reaches cut in value vin, and the output power of the speed-regulating generator to the power grid is Pf.

What is speed regulating wind turbine?

Therefore, the new concept of speed-regulating wind turbine is presented. That is to say, variable wind speed is regulated to a constant speed by the speed-regulating device between the wind turbine and the generator, so synchronous is driven to output constant frequency electric power.

How has technology changed wind power generators?

Meanwhile, the rapid development of power electronics technology has enabled a technological transformation in wind power generators over the past three decades (for example, from fixed-speed low-power wind turbine generators to variable-speed high-power wind turbine generators) 17, 19, 29.

How does wind speed affect output power?

The outer rotor speed nout has already reached the rated value noutN since the wind speed exceeds vωN, whereas the output power Pf of the speed-regulating generator has not reached the rated value PfN; thus, the output power Pf continues to increase as the wind speed rises while the outer rotor speed keeps stable.

Can speed regulating wind turbines reduce the capacity of generator and converter?

Based on the analysis of the characteristics of two kinds of speed-regulating wind turbines mentioned above, a new type of driving chain of speed-regulating wind turbine is proposed in this paper, which achieves speed regulating and generating simultaneously in a certain period of time to reduce the capacity of generator and converter.
