Analysis Method and Application of Protective Device Operation Characteristics Based on Virtual Element Technology

为解决电网故障分析过程中存在的信息收集自动化、信息分析人工化的现状,对故障前后保护装置的动作特性进行可视化和量化分析,提出了基于虚拟元件技术的保护装置动作特性分析方法。该方法将保护装置的功能进行模块化分解为虚拟元件,采用软件可视化技术,对虚拟元件的工作原理和动作特性进行可视化和量化分析,便于运行人员快速处理故障信息,获取保护计算中间结果,以保护虚拟元件为基本单元,还可以生成保护装置动作逻辑,为全面、客观分析保护装置的动作特性,对保护装置的性能进行评价提供辅助手段。

In order to solve the current situation of information collection automation and manual analysis in the fault analysis process of the power grid,the operation characteristics of protection devices before and after the fault are visualized and quantified,and a method for analyzing the operation characteristics of protection devices based on virtual element technology is proposed.This method modularly decomposes the function of the protection device into virtual components,and uses software visualization technology to visualize and quantify the working principle and action characteristics of the virtual components,which is convenient for operators to quickly process fault information and obtain intermediate results of protection calculations.The protection virtual element as a basic unit can also generate protection device action logic,which provides auxiliary means for comprehensively and objectively analyzing the operation characteristics of the protection device and evaluating the performance of the protection device.
