摘要

摘要: 变压器运行状况的好坏直接影响电力系统的安全稳定运行,而噪声是反映变压器运行状态的重要参数,因此针对变压器的噪声监测尤为重要。设计开发了基于5G网络的变压器噪声在线监测系统,由噪声采集、中心管理和网络传输3部分组成。系统界面通过地理信息系统(geographic information system, GIS)噪声监测地图实时监测噪声的发生区域和变电站的噪声变化,判断变压器的运行工况。当噪声发生异常变化时,根据报警信息及时处理,并进行统计分析。结果表明:开发的噪声监测系统在20~130 dB(A)的测量范围内实现了0.1 dB的分辨率,利用5G网络数据传输速率最高可达到10 Gb/s,系统采用快速傅里叶变换(fast fourier transform, FFT)信号处理,测试效率提高了1倍,噪声数据采集率达到95%以上。该噪声监测系统数据准确、操作灵活便捷,能够实现在线实时监测,应用前景广泛。

Abstract: The operation performance of transformer directly affects the safe and stable operation of power system. Noise is an important parameter to reflect operation condition of the transformer, so its monitoring was particularly important. In this study, a noise online monitoring system was designed and developed based on 5 G network and consisted of noise acquisition, central management and network transmission. The system interface displayed the noise area and the noise change of the substation in real time through noise monitoring map in geographic information system(GIS), and judged the operation condition of the transformer. Timely process and statistical analysis were carried out according to alarm information when noise was abnormal. The results showed that a resolution of 0.1 dB was achieved in the measurement range of 20~130 dB(A). The highest data transmission rate was 10 Gb/s using 5 G network. When fast Fourier transform(FFT) signal processing was used in the system, the test efficiency increased by 1 time and noise data collection rate was more than 95%. The noise monitoring system had high precision, and flexible and convenient operation, and could realize online real-time monitoring with wide application prospect.
