摘要
电力网络普遍存在有A平面和B平面两张传输网,其中A平面的网络主要用于PCM、调度数据网、会议电视、通信监控,B平面的网络主要用于综合数据网的业务、视频监控。两个平面的传输网络承载的业务不均衡,为了确保电网的安全生产,有必要将重要的业务同时承载在A/B二个平面上。本文提出了一种带记忆功能E1业务自动保护倒换设计方法 ,实验结果表明采用该方法设计的E1业务保护装置,当主用E1中断后,能自动切换到备用E1通道上,切换时间小于20ms。该E1业务保护装置对电网安全生产有重要实用价值。
The power network generally has two transmission networks, A plane and B plane. The A plane network is mainly used for PCM, dispatching data network, conference TV, communication monitoring, B plane network is mainly used for integrated data network business and video surveillance. Two transmission networks are unbalanced in business. In order to ensure the safe production of power grid, it is necessary to carry important businesses on A/B planes at the same time. In this paper,a E1 service automatic protection switching design method with memory function is proposed. The experimental results show that the E1 business protection device designed by this method can automatically switch to standby E1 channel when main E1 is interrupted, and the switching time is less than 20 ms. The E1 service protection device has an important practical value for the safe production of power grid..
