摘要
分析利用光纤通信网络传送继电保护业务信号需注意的问题和可能采取的方式,可采用PCM复用方式和专用光纤方式,结合具体工程采用PCM复用方式。根据国家颁布的继电保护通道标准中对实时性、可靠性方面的要求,重点讨论了如何改善传输时延和误码性能。
This paper introduces the ways of transmitting protective relaying signals through the optical fiber communication network that include PCM multiplexing mode and private optical fiber channel. The PCM multiplexing mode is adopted in our project. According to request of real time and reliability in national protective relaying signals transmitting standard,the paper discusses how to reduce transmission delay and bit error ratio.
