基于SVG图形的继电保护故障分析技术研究

摘要

继电保护故障分析依赖于装置的录波和保护逻辑图。由于保护逻辑图表达格式缺乏标准化定义，目前故障分析工具不统一，复杂故障分析依赖保护厂家。提出了一种基于SVG图形的保护逻辑图的表达方式，通过标准化的定义输入关联、逻辑关系、连接线等元件，形成标准化保护逻辑关系图，配合标准化的录波文件，清晰地完成继电保护故障分析，解决分析工具不统一的问题。该方案在线路保护装置中实践，证明了方案的可行性。%The fault analysis relies on the wave record and logic diagram of relay protection. Due to the lack of protection logic diagram format standard definition and a unified analysis tool, complex fault analysis depends on protection factory. This paper presents an expression way of protection logic diagram based on SVG graphics. The standard logic diagram is formed by inputting logic cell, operator, connecting lines, etc., through standardized definition. The fault analysis is completed by the standardized recorded wave files and SVG file. The scheme proposed has been used in line protection device, which proves the feasibility of the scheme.
