摘　　要：目前集中式或分布式光伏变电站的子阵主要采用RS485串口方式组网,具有施工周期长、效率低、扩容困难、维护不便等缺点。为了进一步提高组网效率、降低成本,首先对几种无线组网方案进行了比较和探讨,提出了基于Sub-1 GHz技术的多信道光伏子阵无线组网技术,并针对该技术与现有组网方式的兼容性给出了常规的传输配置方式;给出了单位规模下光伏子阵对该技术在容量、传输频段等方面的依赖关系,以及适用于该方案的射频芯片的基本参数性能;最后通过测试论证了该方案在组网和性能方面的优越性,该方案具有适用性强、组网简单、扩容方便、便于维护等优点。At present, the sub array of centralized or distributed photovoltaic substation mainly adopts RS485 serial mode, and has many disadvantages, such as long construction cycle, low efficiency, difficult expansion and inconvenient maintenance. To solve these problems, this paper first compares and discusses several wireless networking schemes, then proposes a Sub-1 GHz based multi channel optical sub array wireless networking technology. According to the compatibility of the technology and the existing networking mode, the normal transmission configuration method is provided. Next, this paper gives the dependence of the technology on capacity and transmission frequency based on a unit photovoltaic array, and the basic parameters of the RF chip is also given. Finally, the advantages of the scheme are demonstrated by tests. The scheme has the advantages of strong applicability, simple networking, easy expansion and easy maintenance.
