地面电站光伏场区通讯方案的应用探讨

Discussion on Application of Communication Scheme in Photovoltaic Field of Ground Power Station

传统地面电站光伏场区通讯方案包含串口通讯、光纤环网通讯、电力载波PLC通讯、无线通讯的模式介绍,改进和优化地面电站光伏场区光纤环网通讯方案,并与传统方案进行技术、经济分析和成本对比;逆变器单独利用智能箱变测控的光纤环网通道,直接与变电站综自监控主站实现“三遥”功能,采用“三合一”智能箱变测控,实现设备系统功能集成化,充分利用智能箱变测控扩展性,解决地面电站光伏场区通讯经济性、可靠性等问题;光伏技术革新、降低成本,加速“531”新政后平价上网。

The traditional photovoltaic fi eld communication scheme of ground power station includes the introduction of serial port communication,optical fi ber ring network communication,power carrier PLC communication and wireless communication mode.The optical fi ber ring communication scheme of photovoltaic fi eld of ground power station is improved and optimized,and the technical,economic analysis and cost comparison with the traditional scheme are made.Inverter using intelligent box alone variable measurement of optical fi ber ring netcom,directly with the substation in the monitoring master station to realize"three remote"function,using the"triad"intelligent variable measurement and control,implement equipment system integration function,make full use of intelligent box tt&c extensibility,solve the ground photovoltaic power station area communication effi ciency,reliability,etc.;Photovoltaic technology innovation,reduce costs,accelerate the"531"after the New Deal parity Internet.
