摘要
为了提高变电站微机综合自动化系统的水平,本文提出了实现变电站微机综合自动化的新型计算机网络结构———面向对象的光互连分布式并行处理计算机网络。保护控制综合单元是“面向对象的变电站微机综合自动化系统”的重要组成部分,是对一次设备实现保护和控制的元件。本文重点研究了保护控制综合单元的构成,即采用基于Transputer和MC68332的异构型2层松耦合并行多处理机系统作为实现保护、控制或人机对话功能的功能单元,将各种功能单元按一定拓扑结构互连构成保护控制综合单元,并对该系统进行了性能分析。研究结果表明,该保护控制综合单元不仅具有很强的并行协调处理能力,而且具有高可靠性、灵活性和可扩展性,以及高速处理能力等优点。
In order to improve the level of integrated substation automation system (ISAS), a new concept of object oriented optical interconnection distributed parallel microcomputer network used to ISAS is established. The protection and control comprehensive unit (PCCU) is an important part of ISAS, which consists of kinds of function unit such as protection unit, control unit and man machine unit. The function unit comprises two levels of loosely coupled multiprocessor system, the first is parallel multiprocessor system based on IMS T800 transputer, the second is STD BUS microprocessor system based on MC68332, the two levels communicate through hard wired links using IMS C011 link adapter. The result indicates that the PCCU has advantages of high parallel processing ability, reliability, flexibility and high speed.
