不同电压等级GIS局部放电UHF信号传播特性仿真研究
|
摘要
特高频局部放电检测是进行气体绝缘组合电器(gas insulated switchgear,GIS)状态评估的一项重要技术手段。通过信号注入方式对特高频传感器在GIS上配置的合理性和局放特高频监测系统灵敏度进行校核是确保状态监测有效实施的重要手段。不同电压等级的GIS结构尺寸不同,对UHF信号的传播和衰减的影响也不相同,因此所需注入校核信号的幅值也不尽相同。文中根据真实GIS建立110、220、500、1 000 kV 4种电压等级下的直腔体、L型、T型仿真模型,通过CST仿真软件对比研究并分析了同一结构下不同电压等级的GIS中UHF信号以及同一电压等级不同结构中UHF信号的传播衰减情况;据此得出了不同电压等级GIS各种典型结构下UHF信号的衰减量,为UHF传感器的配置合理性评价及现场校核信号注入值的确定奠定了基础。
UHF(ultra-high frequency) partial discharge detection is an important technical means for the condition monitoring of GIS,verifying the reasonableness of sensors arrangement and the performance of the monitoring system by the signal injection is an important means to ensure the effective implementation of condition monitoring. The propagation and attenuation of UHF signals vary with different voltage levels GIS structures,so the injection amplitudes of verification pulse are different. In this paper,the simulation models of straight cavity,L type and T type of 110,220,500,1 000 kV GIS are established based on real GIS,comparative study and analysis the attenuation differences and propagation rules of UHF signals of the same structure of different voltage levels GIS and the same voltage level of different structures through CST simulation software. Based on above,the attenuations of various typical structures of GIS with different voltage levels are obtained. Through this research laid a foundation for the reasonable evaluation of UHF sensors arrangement and the amplitude determination of site verification pulse injection.
