基于特高频无线传感阵列的新型局部放电定位方法
|
摘要
对局部放电(partial discharge, PD)有效定位有助于快速检测变电站中电力设备的绝缘劣化,提高检修效率。传统的特高频局部放电定位系统主要基于时差法,但超高采样率带来的硬件开销限制了其推广应用。为此提出了基于特高频无线传感阵列和的接收信号强度(received signal strength indicator, RSSI)指纹法的新型局部放电定位方法。从实用化角度论文还重点讨论了局部放电强度的随机性、多源局部放电干扰以及RSSI指纹图更新这3个问题,并分别提出了归一化算法、聚类算法以及压缩感知算法加以解决。变电站现场测试表明,所提方法的平均定位误差为1.86 m,62.1%的误差小于2 m,验证了所提局部放电定位方法的可行性和有效性。
Effective partial discharge(PD) localization can realize quick detection of the insulation problems of power equipment in substation and improve the maintenance efficiency. The traditional utral-high frequency(UHF) PD localization systems are mainly based on the time-difference information. However, the hardware overhead caused by the ultra-high sampling rate limits their promotion and application. Consequently, we proposed a novel PD localization method based on UHF wireless sensor array and received-signal-strength-indicator(RSSI) fingerprint localization technology. Three significant practical application problems of the proposed method including the randomness of PD strength, the PD interference, and the RSSI fingerprint update were also discussed from the practical point of view, and they were solved by a normalization method, clustering algorithm and compressed sensing algorithm, respectively. A field test in the substation shows that, the mean localization error of the proposed system is 1.86 m, and the 62.1% localization errors are less than 2 m, verifying the feasibility and effectiveness of the proposed PD localization method.
