摘　　要：基于SoundPLAN软件对山东某变电站进行噪声预测,利用实测值反向计算主变压器声功率级,分别根据反推声源和推荐声源建立模型,并将配电装置、电抗器等其他电力设备等效为声场障碍物进行建模,通过反推声源预测结果、推荐声源预测结果和实测值进行比较。结果表明,在模型环境参数及声场障碍物不变的情况下,测点反推声源预测结果比推荐声源预测更接近于实测值,推荐声源值不适用于远声场或有障碍物声场的噪声预测。This paper is based on SoundPLAN software to predict the noise of a substation in Shandong.Using the measured value to calculate the sound power level of the main transformer,modeling the substation according to the calculation result and the recommended sound source,and the power distribution device,reactor and other power equipment are equivalent to sound field obstacles modeling,and compare the prediction result of the sound source,the prediction result of the recommended sound source and the actual measured values.It is found that under the condition of constant environmental parameters and sound field obstacles,the prediction result of sound source derived from the measurement point is more accurate than the prediction result of the recommended sound sourcee,and the recommended sound source is not suitable for noise prediction in far sound field or sound field obstacles.
