摘要
提出了一种基于特高频传感器和信号到达时间差来定位电力变压器内部局部放电的新方法。通过仿真变压器内部所有可能的放电点,建立TDOA数据库,采用切线传输模型和弗洛伊德(Floyd)算法解决信号在变压器内部遇到铁心等障碍物的传输情况。
A new method for locating the internal PD of power transformer based on TDOA of UHF sensor is proposed. By simulating all possible PD points inside the transformer, the TDOA database is established, and the tangent transmission model and Floyd algorithm are used to solve the transmission of signals when they encountered obstacles such as iron core inside the transformer.
