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2G GPRS(通用分组无线服务)和3G 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 Distribution 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 results can provide theoretical guidelines when smart grids are deployed in realistic network.
