摘　　要：在电力检修过程中,以提高对电力设备接地状态的识别精度为目的,研究一种基于电阻式应变传感器的设备接地状态识别方法。首先基于电阻式应变传感器计算接地线坐标信息,并判定节点位置的边界与中心。然后划分电力设备接地状态特征,计算待测线路中不同分路的电压。在等效电路识别时,将接地状态特征分为三类,再通过设计接地状态识别算法完成状态识别。实验结果表明:相比于三种传统方法,所提方法对接地状态的识别精度更高。In order to improve the identification accuracy of grounding status of power equipment during power maintenance,this paper studies a method of equipment grounding status identification based on resistive strain sensor.Firstly,it calculates the coordinate information of ground wire based on resistive strain sensor,and determines the boundary and center of node position.Then it divides the grounding state characteristics of power equipment and calculates the voltage of different branches in the line to be tested.In the identification of equivalent circuit,the ground state features are divided into three categories,and then the ground state identification algorithm is designed to complete the status identification.Experimental results show that compared with the three traditional methods,the method presented in this paper has higher recognition accuracy of ground state.
