变电站光纤通讯中的最优节点选取模型设计

传统变电站光纤通信中最优节点选取模型大多依据先验知识实现,性能较低,不适于实际应用。因此,针对变电站光纤通信设计了一种新的最优节点选取模型,给出变电站光纤通信系统结构,介绍了通信时的信号接收过程和信号传输过程。将所有光电信号的接入端和汇聚中心的通信链路规划为通信栅格网,依据节点功能,从四个方面对变电站光纤通信中的节点进行评价;分别是通信节点处理能力、相邻节点间的通信延迟、相邻通信节点之间的信道质量和误码率。对四种评价指标的权重进行计算,依据权重设计变电站光纤通信中最优节点选取模型。对设计模型的安全性和自身性能进行测试,结果表明,所设计模型安全性优,整体性能强。

Optimal node selection model for optical fiber communication in Substation

Most of the optimal node selection model in traditional fiber communication of substation is based on prior knowledge. It has low performance and is not suitable for practical application. Therefore, a new optimal node selection model for optical fiber communication of substation is designed. In this model, the structure of fiber optic communication system is given, and the signal receiving and signal transmission in communication process are introduced. Then, the communication links of all photoelectric signals'' access terminal and the center are planned as communication grid. Based on the node function, from four aspects, nodes in the fiber optic communication are evaluated, which are communication node processing capability, communication delay between adjacent nodes, channel quality and error rate between adjacent communication nodes. Finally, the weights of the four evaluation indexes are calculated, and the optimum node selection model is designed according to the weights. The results of security and performance testing of the design model show that the model is safe and the whole performance is strong.
