| 摘 要： | 高压开关柜局部放电的准确、快速定位对于及时排除设备故障隐患,保障电力系统的安全稳定运行具有重要的作用.利用四通道暂态对地电压(transient earth voltage,TEV)传感器的多种布置方式,首先将局部放电确定在开关柜某一柜面的某一隔室;基于某一隔室的XFDTD简化模型仿真结果,利用双曲面定位法和空间网格搜索法自行编制程序确定了某一隔室内放电源的具体位置;通过在实验室搭建了高压开关柜局部放电定位试验平台,验证定位方法的有效性.

| Abstract: | The quick and precise locating of partial discharge(PD) inside switchgear is important in eliminating the hidden faults promptly and ensuring the safety and stability of the power system.PD source will be located at a certain compartment of switchgear by setting up multiple sensors with different arrangement.Then,using the hyperbolic method and spatial grid search method can finally determine an accurate position of PD source in a compartment based on the simulation results of a simplified compartment XFDTD model.A switchgear PD location experimental platform is established in laboratory which verify the validity of the positioning method. |
