Research on Load Quantification of Optical Cable in Power Communication Network

With the continuous development of the scale of the power grid, the power communication network, as the second network of the power grid, its topology structure is constantly complicated safe and reliable operation. In this paper, the load quantification model of the network topology layer is established by using betweenness centrality from the perspective of network topology, and the load quantification model of the power business layer is established by using business importance from the perspective of power business. In the physical layer, the physical layer load quantification model is established by using the reliability of the optical cable. The TOPSIS method is used to obtain the comprehensive load quantification model of the power communication network. Finally, the simulation model is constructed and compared with other load quantification models to prove the accuracy of the proposed method. The research conclusions have certain guiding significance for the load quantification, risk protection and network optimization of the power communication network.
