随着智能电网建设的持续深入及智能双向互动概念的提出,本地信道将承载更多的数据量,基于传统的单频窄带载波通信速率相对较低,已不能满足日益增长的网络数据需求量以及传输可靠性的要求。更快速、更可靠、更安全的载波技术是将来发展方向。基于G3-PLC的国际高速窄带标准进行研究,为适应国内的用户数量庞大、台区拓扑相当复杂、信号干扰大的载波环境对G3-PLC的适配层进行了修改,用洪泛组网算法代替6LOWPAN(IPv6 over Low power Wireless personal Area Network,基于IPv6的低功耗无线个域网)。在国内进行了实际台区测试,验证了基于OFDM(Orthogonal Frequency Division Multiplexing)的高速窄带载波具有通信速率高、突发性干扰能力强、通信可靠性高、并行传输纠错性能强等优点。
With the continuous deepening of smart grid construction and the concept of intelligent two-way interaction, local channels will carry more data. Based on the relatively low communication speed of traditional single-frequency narrow-band carriers, they can not meet the increasing demand for network data and Transmission reliability requirements. Faster, more reliable, more secure carrier technology is the future direction of development. Based on G3-PLC’s international high-speed narrow-band standards, in order to adapt to the large number of users in China, the topology of the station area is rather complicated, and the adaptation layer of G3-PLC is modified in the carrier environment with large signal interference. Instead of 6LOWPAN (IPv6 over Low power Wireless personal Area Network, IPv6-based low-power wireless personal area network). The actual station test was carried out in China, which verified that the high-speed narrow-band carrier based on OFDM (Orthogonal Frequency Division Multiplexing) has the advantages of high communication speed, strong burst interference, high communication reliability and strong parallel error correction performance.
