摘　　要：随着物联网技术的发展,智能电网被引入到下一代电网建设中,而现有的电力通信网络建设滞后于电网对数据采集与传输的新要求。针对这种情况,为满足科学、合理的发电、输电和配电的调度,设计了一种用于电网数据采集、传输与处理的通信系统。首先提出了包括家域网、邻域网和广域网的网络结构;然后构建数据协作传输的网络模型,设立中继站执行中继传输来防止数据的拥塞和丢包;最后根据成本最小化原则得出中继站的最佳传输策略。分析结果表明,该系统能够实现在智能电网中获取准确、及时的用电数据,达到科学调度电网资源的目的。With the development of IOT technology, the smart grid is introduced into the next generation of electric power network con- struetion. But the requirement of data acquisition and transmission is difficult to be satisfied in the existing communication network in the grid. To meet the scientific and rational scheduling of power generation,transmission and distribution,a communication system used for data transmission in smart grid is designed in view of the demand for reliable data acquisition and transmission. A network structure inclu- ding home area network, neighborhood area network and wide area network are proposed in the system. Relay stations are deployed to perform relay transmission to prevent the congestion and loss of the packet. The optimum transmission strategy of relay station is obtained according to the cost minimization principle. Analysis results show that electricity data can be acquired accurately and timely in the smart grid by using this system. The goal of achieving the best scheduling of grid resources is reached.
