Design of Power Supply Source of Transmission Line On-line Monitoring Device

为解决输电线路在线监测装置供能不足的问题,提出平面反射式结构的太阳能电源。该结构基于光反射原理,利用反光膜将垂直方向的太阳能光反射至太阳能板,由此增大太阳能板接收太阳辐射能的有效面积,从而提高太阳能电源的供电可靠性。基于此原理,设计并研制了平面反射式结构的太阳能电源,并在晴天、多云、阴天、雨天天气条件下,与传统平板式太阳能电源开展对比实验研究。实验结果表明:平面反射式太阳能电源的平均输出功率高于平板式太阳能电源,且具有更好的弱光效应。最后,以南方电网对输电线路在线监测装置的功耗需求为例,完成太阳能电源的应用方案设计。

In order to solve the problem of insufficient power supply of the transmission line on-line monitoring device, this paper proposes a kind of solar power source with planar reflection structure. This structure is based on optical reflection principle and uses the reflective sheeting to reflect solar light along vertical direction to the solar panels so as to increase ef- fective areas of the solar panels receiving solar radiation energy and improve power supply reliability of solar power source. On the basis of this principle , it designs and develops solar power source with planar reflection structure and makes compari- son with traditional flat solar power source under different weather conditions including sunny day, cloudy day and rainy day. The experimental results indicate the average output power of the planar reflection solar power source is higher than that of the flat solar power source and has better weak light effect. Finally, it finishes application scheme designs for solar power source by taking power consumption demand of the transmission line on-line monitoring device by CSG as an example.
