摘要
在电力自动化系统中,数字远动得到了广泛应用,它传输速率高、信息量大、抗干扰性好,但受传输通道的特性影响较大。文章介绍了一种数字远动通道监测系统,并就DNP规约的数字远动通道监测进行了研究,给出了系统的设计思想和实现方法。系统实现了对通道性能的监测,并对通道故障进行了预告警。应用结果证明了该系统的实用性,对执行不同规约的远动系统,只要解决好智能匹配问题,就能实现对各种数字远动通道的监测。
Digital remote control has been applied widely to electric power automation system for its advantages of higher transmission speed and anti-interference performance. But its performance is affected by the transmission channel. This paper introduces a monitoring system for digital remote control channel, puts forward the design principle and its realization. The system can monitor the performance of the channel and has the function of pre-alarm on channel faults. The application results prove its practicability.
