嵌入式技术在电力系统中的应用

Applications of Embedded Technology Power System

介绍了嵌入式系统的定义、特点及其硬、软件资源，尤其是嵌入式在电力系统中运用的重要意义；介绍了嵌入式在数据采集与监控（SCADA）、微机保护、电力系统自动装置、电费计量、电力信息网络安全隔离、电力系统遥视、远程监控等方面的广泛应用。最后，指出了嵌入式在电力系统的可扩展性、实时性、可靠性、网络通信能力、人机接口等方面有很好的发展前景。

The artile presents the characters and definition, then current embedded hardware and software technology briefly separately were introduced, especially the impotance of embedded real -time database＇s application in power system were pointed out at the same time. subsequently the applications of embedded system on supervisory control and data acquisitor （ SCADA）, microcomputer based protection, transient stability control （ of automation devices）, electric power information net insolation safely, the remote monitoring of electric power system, the remote superviser and compution of charge and so on in power system were summarized. Finally some ideas of the developments of embedded system were brought forward such as enhancement of the abilities of real - time, reliability, expansibility , network communications, human - machine interface, etc.
