一种带光纤数字接口的继电保护装置的研究

Study on an integrated protection with digital optical interface

简单介绍了一种带光纤数字接口的继电保护装置 ,它通过光纤以太网按照IEC6 185 0 9 1的通讯协议 ,接收由前端光纤电力互感器传送过来的数字量采样值。该装置采用了双CPU结构 ,其中主保护CPU采用了带以太网接口的 32位RISC微处理器MCF5 2 72 ,它负责完成接收采样值及保护计算的任务。从CPU采用了80C196KC ,主要负责人机接口和通讯功能。两个CPU之间通过双口RAM来交换数据。

this paper introduces an integrated protection set with digital optical interface simply.It receives digital sampled values from optical electric transformer through its optical Ethernet interface. This set applies double CPU configuration, one is 32 bits RISC MCU with Ethernet interface.This CPU is assigned a task to receive sampled values and carry out calculation for protection.
