摘要/Abstract

摘要：

电力系统缺少明确的电力通信系统可靠性定义和定量的测度判据,仅用通信通道中断衡量通信网的可靠性不科学,不能客观反映通信网的真实运行情况. 前人的研究并没有考虑非线性影响,对传输性能的估计十分粗糙,也没有考虑自相位调制和色散导致的性能劣化影响. 因此在前人工作的基础上,综合考虑线性和非线性影响,采用光脉冲展宽作为评估指标,通过理论计算接收端光脉冲的展宽来估计系统传输代价. 最后通过仿真验证传输性能评估的可行性和有效性.

Abstract:

The electric power communication network system as an important information infrastructure of electric system requires high transmission reliability. However, it lacks a clear definition of system reliability and a quantitative measure of the criterion. This article briefly introduced application of transmission performance damage assessment technology in power telecommunication networks, and pointed out the importance of the transmission link damage assessment. The authors used the optical pulse broadening as the evaluation index and calculated the optical pulse broadening to estimate the system transmission penalty. The binary polynomial fitting is used to obtain a more accurate assessment of the linear empirical formula. It was verified by comparing with different simulation parameters to have good feasibility and effectiveness.

Key words: electric power communication, optical pulse broadening, damage assessment, optical signal to noise ratio
