嵌入式技术及其在电力系统中的应用

Embedded technology and its applications on power system

首先阐述了嵌入式系统的特点与含义 ,并分别介绍了嵌入式硬件与软件技术的发展现状 ,其中强调指出了嵌入式实时数据库在电力系统应用中的重要意义 ,随后就嵌入式系统在电力系统数据采集与监控 (SCA DA)、微机保护、自动装置 (以暂稳控制为例 )、电费计量等方面的广泛应用做了简要介绍 ,最后指出嵌入式技术要想更好地满足电力系统的要求必须在实时性、可靠性、可扩展性、网络通信能力。

The author presents the characters and signification of embedded system at first, then introduces current embedded hardware and software technology briefly separately. Especially the importance of embedded real-time database's application in power system is 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), computation of charge and so on in power system are summarized. At the end some ideas of the developments of embedded system are brought forward such as enhancement of the abilities of real-time, reliability, expansibility, network and communication, man-machine interface and so on.
