基于宽频超声传感器的发电机定子线棒放电超声信号特征分析

Gaoya dianqi
大型发电机定子线棒对电力系统发电机组至关重要，其绝缘性能关乎发电机及电网稳定安全，电晕放电引发的绝缘腐蚀击穿事故频发。由于之前大多数研究是将传感器安装在发电机组的外壳上，并且主流谐振式传感器对于检测不同频率的超声信号有局限性，不能准确反应其时频域特点。为此文中使用宽频超声传感器检测定子线棒放电超声信号，从而获得不同类型信号的特征，为以后基于超声信号的线棒放电在线监测诊断提供基础。首先通过电场仿真确定传感器最佳安放位置，然后设计局部放电试验验证宽频传感器可行性，最后对超声信号进行时频域和相位的特征分析 ...

基于实测和Matlab仿真波形比较的10 kV配电网单相接地故障暂稳态特征信息融合选线方法研究

Dianci bileiqi
10 kV配电网单相接地故障稳态选线方法受故障电阻、谐振接地电网补偿的影响较大，且信噪比较低；而暂态选线方法虽然信噪比较高，且受故障电阻、谐振接地电网补偿的影响较小，但具有依赖特征频带选取以及信号持续时间短，信号与暂态干扰信号产生混叠严重的特点。为了进一步提高选线成功率，本研究探索了一种融合暂稳态特征信息的选线方法，通过在Matlab仿真平台中搭建10 kV配电网系统的高精度pi模型网络，分析故障信号的暂稳态特征，在三相不平衡、支路开合闸等干扰条件下 ...
