DEVELOPMENT OF A MODEL FOR IMPROVING THE EFFICIENCY OF ELECTRICAL ENERGY TRANSMISSION THROUGH OPTICAL FIBERS USING LIGHT.

This paper investigates the problem of improving energy transmission efficiency in Power-over-Fiber (PoF) systems. The limitations of the Beer-Lambert-Bouguer law under high-power laser conditions are analyzed in detail, and an enhanced mathematical model accounting for thermal and nonlinear effects is proposed. An Adaptive Power Injection (API) heuristic control algorithm is developed to maximize system efficiency. Simulation results demonstrate a reduction in energy losses by 12–14%, an increase in the coefficient of performance by 9.5%, and an extension of the transmission distance from 2 km to 5 km.本文研究了光纤供电（Power-over-Fiber, PoF）系统中提升能量传输效率的问题。本文详细分析了高功率激光工况下比尔-朗伯-布格定律（Beer-Lambert-Bouguer law）的局限性，并提出了一种考虑热效应与非线性效应的改进型数学模型。本文开发了一种自适应功率注入（Adaptive Power Injection, API）启发式控制算法，以最大化系统效率。仿真结果表明，该方案可使能量损耗降低12%~14%，性能系数提升9.5%，并将传输距离从2公里拓展至5公里。
