摘要

在IEC 61850标准基础上，提出一种基于PowerPC、数字信号处理器（DSP）、总线低电压差分信号（BLVDS）高速串行总线的数字化集中式保护方案。PowerPC硬件平台加VxWorks实时操作系统完成过程层的数字化采样和通用面向对象变电站事件（GOOSE）出口跳闸功能，DSP保护模块完成测控与保护运算功能，PowerPC与DSP之间通过背板BLVDS高速串行总线进行通信。重点介绍系统方案、过程层的软硬件平台和数字化采样的实现。系统测试结果表明，基于PowerPC，DSP，BLVDS串行总线的平台方案能够很好地满足数字化集中式保护的要求。

Abstract

With the development of IEC 61850 digital substation standard， a digital integrated protection scheme based on PowerPC， DSP and BLVDS is proposed. Platform made of PowerPC with VxWorks is used to complete digital sampling and sending GOOSE packet. DSP protection module is used to accomplish functions of measuring and control， and protection algorithm as well. Data stream between the above two CPUs are exchanged through high speed BLVDS bus. This paper mainly emphasis on system scheme， hardware and software platform in process level and implementation of digital sampling. System test proves that platform based on PowerPC， DSP and BLVDS can definitely satisfy requirements of digital integrated protection.
