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.
The power system lacks a clear definition of the reliability of the power communication system and quantitative measurement criteria. It is unscientific to measure the reliability of the communication network using only the communication channel interruption, and can not objectively reflect the actual operation of the communication network. Previous studies did not consider the non- Linearity, the estimation of transmission performance is very rough, and no consideration is given to the performance degradation caused by self-phase modulation and dispersion. Therefore, based on the previous work, taking the linear and nonlinear effects into account, the light pulse broadening is used as the evaluation index, The system transmission cost is estimated by theoretically calculating the broadening of the light pulse at the receiving end.Finally, the feasibility and effectiveness of the transmission performance evaluation are verified through simulation.
