500kV变电站噪声源强迭算与预测方法优化
Calculation of Noise Source Intensity and Optimization on Prediction Method for 500kV Substation
摘要
Abstract
In order to improve prediction accuracy of substation noise, it is required to establish the noise source intensity database and optimize the prediction method.According to measured data outside and inside five representative 500 k V substations of Sichuan pow er grid, this paper adopts the noise source calculation method to obtain noise source intensities and spectrum characteristics of the main transformer, the high-voltage reactor, the low-voltage reactor, the capacitor and the amour clamp.M eanw hile, it uses methods such as simplifying layout of the main sources as vertical area source and the technology of partitioned terrain fitting assistant control plane to optimize prediction method for substation noise.By means of Cadna/A modeling prediction, it obtains close results of prediction and monitoring of noise outside and inside the substation, w hich indicates this prediction method can accurately reflect noise of the substation.关键词
