Intelligent Modeling Method for Protection Signals Based on Section Division

针对当前调度自动化系统无法实现来自变电站端保护信号和主站电网模型自动匹配的问题,提出一种基于间隔划分的保护信号智能建模方法,实现对保护信号进行自动间隔匹配。该方法基于电网拓扑结构,通过深度优化搜索方法,实现对间隔范围、类型智能识别和划分,并采用基于关键字匹配规则和基于字符串特征相似度的模糊匹配算法相结合的方法,实现对保护信号的智能建模。

Aiming at the problem that the current dispatching automation system can not automatically match the substation side protection signal and the main station network model,an intelligent modeling method based on section division is proposed to realize automatic automatical matching of the section protection signal.The method is based on the grid structure of the grid,and realizes the intelligent identification of section type and range and the section division through the deep optimization search method,and adopts a method based on the keyword matching rule and the fuzzy matching algorithm based on the string feature similarity to achieve the Intelligent modeling of protection signals.
