摘要
智能变电站以过程层网络方式取代了传统变电站通过电缆传输一次设备与间隔层设备信号的方式,但存在报文传输延时长且不可控的问题,为此提出2种基于无缝冗余协议的新型智能变电站通信组网方式,一种是将星形网络与并行冗余协议(parallel redundancy protocol,PRP)相结合构成的PRP双星形网络,另一种是高可用性无缝冗余协议环网。设置了基本网络、网络故障、网络雪崩等3种场景进行仿真实验,仿真结果显示,这2种基于无缝冗余协议的通信组网方式都具有良好的实时性与可靠性,能够代替现阶段常规的组网方式,且PRP双星形网络的最大报文传输延时最短。
The smart substation adopts process layer network mode to replace transmission way of the traditional substation for signals between the primary equipment and the interval layer equipment by cables, but there are problems of long delay and uncontrollability in message transmission. Therefore,the paper presents two kinds of new communication networking modes of the smart substation based on seamless redundancy protocol, one is a kind of parallel redundancy protocol （PRP） with double star network,, the other is high available seamless redundancy protocol loop network. It sets three scenes inclu-ding basic network, network failure and network avalanche for simulating experiment. Results show these two kinds of com-munication networking modes both have good real-time performance and reliability, which means these two modes can re-place conventional networking modes at present. And message transmission delay of the PRP with double star network is the shortest .
