摘要

为了实现变压器保护的就地化

提出了一种分布式解决方案

按开关配置就地采集及跳闸的保护子机

子机之间通过高可靠无缝冗余(HSR)双向环形高速网络交互数据

其中高压侧保护子机集成主后备一体化保护功能。在总体实现方案分析的基础上

着重论述了环网通信机制和采样同步机制。理论分析与实测数据表明

相比于现有的集中式变压器保护装置

所提出的分布式变压器保护在可靠性和快速性方面具有一定的优势。

Abstract

In order to make the transformer protection outdoor installation

an implementation scheme of distributed transformer protection is proposed. Distributed sub protection machines

which transfer data between each other through the high-availability seamless redundancy(HSR)bidirectional ring network

are installed for each switch of transformer. The high-voltage side sub machine integrates the main and backup protection function. After an analysis of the overall scheme

focus is on the key technologies of the ring network communication and sampling synchronization. Theoretical analysis and experimental data show that

compared with the existing centralized transformer protection device

the distributed transformer protection has definite advantages in terms of reliability and rapidity.
