基于GPRS的配网自动化系统性能分析

Performance analyzing of GPRS-based distribution automation system

在配网自动化系统中,系统的安全性和可靠性是配电网正常运行的保证,同时,合理的通信计费方式也是配网自动化系统迅速发展的关键,现有的通信方式都不能很好的满足系统要求。随着移动通信技术的发展,GPRS技术可以提供高速可靠的无线连接,从而为工业自动化提供了一个理想的解决方案。文章介绍了GPRS网络及其优势,提出了一种基于GPRS网络的配网自动化系统设计方案,并重点对系统的安全性、QoS和计费方式进行了分析。分析表明,通过架设专线和设置相关参数,GPRS系统可以很好的满足系统要求。

In distribution automation system, the security and reliability are the guarantee for normal operation in distribution network, at the same time, the reasonable way of communication expense counting is the key to develop distribution automation system. The existing ways of communication can＇t satisfy the need of the system very well. With the development of mobile communication, GPRS can provide reliable wireless access with high data rates and gives a good solution for applications of industrial automation. In this paper, the GPRS transmission networks and its advantages are introduced, and a design for distribution automation system, which is based on GPRS transmission networks, is put forward, and its security and the QoS and the counting expenses ways are especially analyzed. The results show that through fixing private circuitries and setting relational parameters, GPRS can satisfy the system demand very well.
