摘　　要：高压电力电容器是变电站高效输送电能或提高电能质量的重要设备,但是电容器在运行过程中所产生大量的声音可能影响周围环境,甚至干扰周围电子设备的正常运行。为此文中提出了一种能够基于参考电压预测变电站环境中高压电力电容器可听噪声的模型。实验室和现场实验的结果表明,基于该模型的噪声预测具有良好的准确度。High-voltage power capacitor is one of important equipments for substation to efficiently transfer electrical energy or improve power quality.A large amount of sound generated by capacitors during operation may affect the surrounding environment and even interfere with the normal operation of surrounding electronic equipment.In this paper,a model that can predict the audible noise of high-voltage power capacitors in substation environment based on reference voltage is proposed.The results of laboratory and field experiments show that the noise prediction based on this model has good accuracy.
