The existing transformer monitoring and testing devices operate independently without uniform standards,which makes it impossible to share data and to conduct comprehensive diagnosis of transformers based on multiple parameters within the same system.To solve this problem,a unified data reading and communication method is proposed in this paper.A unified communication framework is designed for on-line monitoring device,and the transformation method of private protocol and I0 protocol in smart substation condition monitoring system is proposed.The method of mapping big data and MODBUS register address is proposed,and the method of transforming the data of partial discharge monitoring device from unified XML file format and private file format to this format is put up.The practicability of our method is verified by the experimental results of the on-line and off-line monitoring devices.This method can advance the share application of isolated data of independent monitoring devices,and provide communication and data solution for integrated diagnosis of transformers.%现有变压器监测及检测装置独立运行、规范不一致,造成数据无法共享,难以在同一个系统中实现基于多参数的变压器综合诊断,为此提出了统一数据读取和通信方法.设计了在线监测装置统一通信框架,提出了私有协议与智能变电站状态监测系统站内I0规范的转化方法.为解决I0规范不便于读取较大数据文件的问题,提出了数据与MODBUS地址之间的多对一映射方法.给出了局部放电检测装置数据的统一XML文件格式及私有格式数据向该格式的转化方法.选取典型厂家的在线监测和离线检测装置进行实验,验证了方法的可行性,该方法可推进独立监测装置孤立数据的共享应用.
