The invention discloses a method for preventing generator set from generating resonance. When a generator set is designed, a tooth socket harmonic frequency range of the generator and the natural resonance frequency of the generator set are calculated; then it is determined whether the natural resonance frequency is located in a harmonic frequency range or not; and if yes, adjusting the natural resonance frequency to allow the natural resonance frequency to be located out of the harmonic frequency range. The method can determine whether the natural resonance frequency of the generator set is located in the harmonic frequency range of the generator tooth socket or not when the generator set is designed, if yes, the natural resonance frequency is adjusted to allow the natural resonance frequency to be located out of the harmonic frequency range to reduce the probability of generation of the resonance by the generator set, and the timeliness is improved and the time and the labor are saved compared with the conventional solution. In addition, the invention also discloses an apparatus and a device for preventing a generator set from generating resonance, and the effects are as above.
Description
technical field [0001] The invention relates to the field of wind power, in particular to a method, device, equipment and storage medium for preventing resonance of a generating set. Background technique [0002] Due to the particularity of the wind power industry, generators and converters are usually designed and produced by different manufacturers. At the beginning of wind turbine design, generator manufacturers and converter manufacturers lack sufficient technical communication. In the process, the product design is carried out more from the perspective of its own product design, and less consideration is given to the impact of the design of the generator on the converter or the generator that the design of the converter needs to adapt to. Converter manufacturers or generator manufacturers have weak overall design capabilities for the entire power generation system of wind turbines. The generators and converters produced are assembled and debugged by wind turbine manufac...
