无线公网2G/3G技术在智能电网中的应用

摘要

智能电网是国内外电网技术发展的必然趋势，而配网自动化管理系统的建设是关键环节。文章介绍了利用无线公网技术建设智能配电网的优势，并具体结合2 G GPRS(通用分组无线服务)和3 G WCDMA(宽带码分多址)技术承载配网自动化业务中的低压集抄业务的应用场景，对无线公网承载智能电网业务的性能进行了理论分析与仿真验证。得出的相关结论拓宽了智能电网的建设思路，具有一定的理论参考价值。%The past few years has witnessed the inevitable trend of the development of smart grid,where the construction of Dis-tribution Automation Management System is a key component.This paper discusses the performances and advantages of using broadband wireless communication technology to construct the smart grid.The operation of low-voltage meter reading is based on the combination of the second generation mobile communication technique-General Packet Radio Service (GPRS)and the third generation mobile communication technique-Wideband Code Division Multiple Access (WCDMA).Then we evaluate the system performance of smart metering application operated in GPRS system as well as WCDMA system.The simulation re-sults can provide theoretical guidelines when smart grids are deployed in realistic network.
