太阳能中继器在10kV配网线路中的应用设计

Application Design of Solar Repeater in 10 kV Distribution Network

本文针对10kV配电网数据采集系统中传统有线中继器采用开关电源供电成本高、结构复杂、安装繁琐的问题,提出一种新型太阳能供电无线中继器,通过太阳能电池板结合中继器内置蓄电池实现日照无差别供电功能。为保证数据传输稳定性及易用性,详细阐述了无线通信、GPS定位及手机模块的设计。太阳能中继器可将故障检测装置检测到的电流、电压及故障信息传送给后台主站,帮助检修人员实现快速抢修,提高供电可靠性。

For the traditional wired repeater in the data acquisition system of 10 kV distribution network,the problem of high cost,complicated structure and cumbersome installation of switching power supply is proposed.This paper proposes a new type of solarpowered wireless repeater,which mainly uses solar energy.Inexhaustible features,through the solar panels to convert light energy into electrical energy,and combined with the built-in battery of the repeater to store the remaining electrical energy,so as to achieve the power supply function of the repeater during the absence of sunlight.The system is mainly composed of a background main station,a fault detecting device and a solar relay.The solar relay is responsible for transmitting the current,voltage and fault information detected by the fault detecting device to the background main station,and the user can pass the background master station and the mobile phone.The APP performs remote signaling,telemetry and remote control on the distribution line.The system operation results show that the designed solar repeater is reliable in operation,stable in data transmission,reduces the cost of use,and has great market application and promotion prospects.
