摘要
为分析研究适于预测变电站主变噪声的模型,本文对某一典型500k V变电站主变噪声进行了现场采样,并采用不同模型在Cadna/A软件中对主变噪声影响进行预测。结果表明,500k V主变采用C1模型(即5个面声源建模,并在面声源内部增加一个建筑物),实测值与Cadna/A软件预测值之间的差异较小。由此可见,该模型更适用于预测500k V主变近场区噪声影响。
In order to select the best model for predicting the main transformer noise of 500 k V transformer substation, the noises of a typical 500 k V substation were sampled and different prediction models of main transformer noise were built by software of Cadna/A. As the results shown, the measured values were closest to the prediction results of Model C1, which was built by 5 area sound sources and a building inside. Thus, Model C1 was more suitable to predict the influence of 500 k V main transformer noise in the near field region.
