摘　　要：随着使用时间的增长,变压器面临着各种潜在的故障风险,为尽可能降低故障发生概率,对变压器进行异常检测和继电保护就尤为重要,本文提出的利用传感器实时监测采集电力系统的电气量(如电流、电压、频率等),并将其转换为数字信号进行处理,实现对电力系统故障的快速、准确判断。同时再通过设定阈值和逻辑算法来进一步优化智能继电保护动作,以提高变压器的继电保护效果。With the increase of usage time,transformers face various potential fault risks.In order to minimize the probability of fault occurrence,it is particularly important to perform abnormal detection and relay protection on transformers.This paper proposes using sensors to monitor and collect real-time electricity and gas volume(such as current,voltage,frequency,etc.)of the power system,and convert it into digital signals for processing,achieving fast and accurate judgment of power system faults.At the same time,further optimization of intelligent relay protection actions is achieved by setting thresholds and logic algorithms to improve the relay protection effectiveness of transformers.
