摘要
变电站测控防误闭锁逻辑受现场环境复杂多变的影响,会导致了防误闭锁逻辑校验难度大、精度低,本文提出一种新的变电站测控防误闭锁逻辑可视化智能校验方法。首先解析不同类型的变电站测控防误闭锁逻辑标准,然后根据逻辑标准构建面向多种逻辑的逻辑编码广域模型,最后利用该模型转换逻辑编码格式,建立智能校验的线性回归方程,结合数据可视化过程实现防误闭锁逻辑校验。实验结果表明:应用本方法对变电站测控防误闭锁逻辑进行检验的误闭锁率为1%~6%,波动较小,表现出的PR曲线平衡点优,校验精度高,能满足变电站测控工作运维管理需求。
The anti-misoperation locking logic of substation measurement and control is affected by the complex and changeable environment on site,which will lead to the difficulty and low accuracy of anti-misoperation locking logic verification.This paper proposes a visual intelligent verification method for anti-misoperation locking logic of substation measurement and control.Firstly,different types of substation measurement and control anti-misopera⁃tion locking logic standards are analyzed.Then,a wide-area model of logic coding for multiple logics is constructed according to the logic standards.Finally,the model is used to transform the logic coding format,and the linear re⁃gression equation of intelligent verification is established.Combined with the data visualization process,the an⁃ti-misoperation locking logic verification is realized.The experimental results show that the false locking rate of the substation measurement and control anti-misoperation locking logic is 1%~6%,and the fluctuation is small.The PR curve has excellent balance point and high calibration accuracy,which can meet the operation and maintenance management requirements of substation measurement and control work.
