- 摘要：
- In order to predict the levels of corona noise from high-voltage AC power transmission lines, the mechanism of corona noise and the corresponding theoretical prediction model are investigated. On the basis of Drude model, the motion of positive and negative ions produced by high-voltage corona is analyzed and the mechanism of corona noise is discovered. Then a theoretical prediction model is put forward by use of Kirchhoff formula, which is verified by the well agreement between our result and others’ considering the case of three-phase single lines. Moreover, the calculation results show that for both single and bundled lines the sound pressure level of the typical frequency, i.e. twice the power frequency, attenuates slowly and leads to an obviously interferential phenomenon near the transmission lines, but the level of the bundled lines is smaller under the same transmission voltage. Based on the mechanism of corona noise and the prediction model, it is obvious that bundled lines and/or increased line radius can be adopted to effectively reduce corona noise in the practical engineering applications. This model could also provide a theoretical guidance for the high-voltage AC transmission line designs.
