Research on Construction Feasibility and Typical Construction Scheme of Wireless WAPI Local Area Network in Substations

随着智能电网建设和数字化转型的推进,变电站出现了以机器人巡检、移动作业、物联网数据采集为代表的新型业务,这些业务总体呈现出大带宽、高移动、大连接特点,变电站亟需建设覆盖全站的无线网络,为变电站无线高清视频监控、巡检机器人、移动办公和作业、远程调度、应急通信等以及其它智能化监测监控系统应用提供终端部分的无线接入通道,解决高带宽业务的安全可靠接入和各类智能感知业务最后一公里通信需求。WAPI(WLAN Authentication and Privacy Infrastructure)技术具有组网灵活、网络扩展性好、融合性好、兼容性高、通信速率高以及与互联网对接方便等优点,更重要的是其安全性高,可实现变电站建设无线WAPI局域网便能满足各类智能化监测监控系统对无线接入的需求。

With the advancement of smart grid construction and digital transformation, new services such as robot inspections, mobile operations, and IoT data collection have emerged in substations. These services generally present the characteristics of large bandwidth,high mobility, and large connections. There are urgent needs to build a wireless network covering the entire substation to provide the wireless access channel for terminals of the substation wireless high-definition video surveillance, inspection robots, mobile office and operation, remote dispatch, emergency communication, as well as other intelligent monitoring systems, thereby meeting the needs of secure and reliable access of high-bandwidth services and the last-mile communication of various intelligent sensing services. WAPI(WLAN Authentication and Privacy Infrastructure) technology has the advantages of flexible networking, good network extensibility, good integration, high compatibility, high communication rate, and convenient connection with the Internet. Moreover, due to its high security,the construction of wireless WAPI local area network can meet the needs of various intelligent monitoring for wireless access.
