基于光通信芯片的配电光通信解决方案
|
摘要
目前国网实施配电自动化的城市中,其通信系统绝大部分采用基于以太网无源光网络(ethernet passive optical network,EPON)光通信技术。提出一种配电光通信解决方案,其特点是基于配用电专用ONU芯片设计光网络单元(optical network unit,ONU),将ONU内嵌到配电终端中;同时将加密安全模块集成到ONU模块中。与传统配电通信EPON解决方案相比,该方案综合考虑了配电终端通信系统的功能、性能,其将ONU模块与配电终端进行一体化设计,降低了模块功耗。通过配网现场试点表明,该方案不但能实现传统EPON方案的环网保护、大数据量高速、实时接入等功能,而且在系统功耗、安全、可维护性、经济性等方面具有较大优势。
Now in cities where SGCC implements distribution automation, the communication system mostly adopts ethernet passive optical network(EPON) based optical communication technology. This paper proposes a distribution optical communication solution, which is based on the chip of optical network unit(ONU) designed specially for the electrical distribution and utilization. The ONU is embedded into the power distribution terminal, and at the same time, encryption security module will be integrated into the ONU module. Compared with the traditional power distribution communication solution applying EPON, the scheme comprehensively considers the function and performance of the communication system of distribution terminal. The integrated design of the ONU module and the power distribution terminal reduces module's power consumption. And the field trial of distribution network shows that the scheme can not only realize functions such as ring protection, huge data quantity's high-speed and real-time access that traditional EPON solution can achieve, but also has greater advantage in respects of system power consumption, security, maintainability and economy, etc.
