摘　　要：探索电力系统中应用量子技术的可行性,针对电力行业的特殊性,尤其是电力架空光缆对其传输光子偏振态的影响,提出了一种新颖的快速偏振反馈补偿技术方案。该方案能够快速补偿信道中的偏振变化量,有望拓宽QKD系统在电力领域的应用范围。Explored the feasibility of QKD applied to state power grid for enhancing its security and proposed a new technology which will overcome the obstacle of rapid polarization fluctuation in an aerial optical fiber assembled with power transmission line. A fast polarization control theme with real-time feedback is used for dynamically compensating fiber channel drifts and thus makes the quantum key distribution more robust for power grid system usage.
