【摘要】 针对电力线路保护系统存在的可扩展性差和开发成本高的问题,探讨了一种集保护、控制和远程监控于一体的微机保护及变压器的经济运行控制系统。基于MCF5282微处理器设计了一个110kV线路的微机保护系统,讨论了嵌入式硬件平台构架、相关功能模块和软件系统的改进设计,并对信号采集、数据处理、变压器经济运行原理及设备自投的实现等问题进行了研究。更多还原

【Abstract】 Aiming at the problems that it is bad in expansibility and higher in development cost for line relay protection of power system, the paper explored a sort of control system that it is integrated by the function of protection, control and remote monitoring for the microcomputer protection and economic operation. The paper designed a microcomputer protection system for 110 kV line based on MCF5282 microprocessor, discussed embedded hardware platform architecture, the related function module and improved the designing of software system. And also it is researched to signal acquisition, data processing, economic operation principle and auto-link realization of transformer and so on.更多还原
