太阳能电池在电子电流互感器高压侧供能的研究

针对高压光电式电流互感器（Optical Current Transformer，简称OCT）的高压侧供能问题．提出利用太阳能电池为高压侧供能的电源设计方案。太阳能电池在日照充足时对锂电池充电、同时为高压侧电路供能：在夜间或目照不足时，锂电池接替太阳能电池向高压侧电路供电。该电源控制采用单片机，可实现光伏器件的输出功率控制和锂电池的充放电智能化管理。实验表明，由太阳能电池构成的OCT高压侧电源工作可靠，町满足系统在连续阴雨气候条件下的正常工作。

Research of OCT Power System based on Solar Cell

Optical current transformer(OCT) is the hotspots in power system current measurement.This paper discusses how to apply solar cell in OCT high voltage side power supply.The solar power supply system is composed of solar cell,Li battery,charge circuit,control and protect circuit.Under good illumination conditions,the solar cell provides power for both Li battery and OCT system.The Li-battery supplies power for OCT system when the illumination decreases.Experimental results show the solar power system can prov...
