【摘要】 随着新能源技术的发展,塔内中继光放大技术将在电力系统超长站距光传输链路中得到广泛的使用。为了使塔内中继器在给定的链路配置下工作在最佳状态,对塔内中继器的配置进行了理论建模与数值仿真。通过对信号的光信噪比与增益特性的综合考虑,获得了塔内中继器的最佳位置以及中继器掺铒光纤的最佳长度。最后,对实际工程进行了设计和挂网运行测试,论证了本优化方法的正确性。更多还原

【Abstract】 With the development of advanced energy technologies,optical amplification technique will be widely applied in ultra-span optical transmission link in electric power systems.To make the regenerator within power tower perform optimally under given conditions,theoretical modelling and numerical stimulation are carried out for the regenerators within power tower.The optimal regerenator location and optimal erbium-doped fiber length in the regenerator are obtained by taking into account the regenerator gain and optical signal-to-noise ratio synthetically.Finally,the design and in-line test are taken in the practical communication systems and the validity of the proposed optimized approach is verified.更多还原
