发布时间：2019-07-21 09:54
【摘要】：要实现基于电流差动原理的智能变电站站域后备保护,需要获取相邻变电站的SV和GOOSE信息,为此研究了变电站之间的信息传输方案。满足带宽和实时性要求的SV传输方案有以下三种:借用光纤纵差保护装置转发的方案、采用专用数据转发装置的方案和广域以太网扩展变电站过程层网络的方案。经过性能对比分析,第三个方案互操作性好、数据带宽高,最适合于站域后备保护的实际应用。对第三个方案从SV数据的同步性、数据通道带宽、通信传输距离及可靠性、数据传输延时等几个方面进行了初步分析,表明采用该方案在智能变电站之间透明传输SV和GOOSE信息是可行的。最后指出了实用化过程中需要进一步研究的内容和可能存在的问题。
[Abstract]:In order to realize the backup protection of intelligent substation station domain based on current differential principle, it is necessary to obtain the SV and GOOSE information of adjacent substations. Therefore, the information transmission scheme between substations is studied. There are three SV transmission schemes to meet the requirements of bandwidth and real-time: the scheme of using optical fiber longitudinal differential protection device to forward, the scheme of using special data forwarding device and the scheme of extending substation process layer network with wide area Ethernet. Through performance comparison and analysis, the third scheme has good interoperability and high data bandwidth, so it is most suitable for the practical application of station domain backup protection. The third scheme is analyzed from the aspects of SV data synchronization, data channel bandwidth, communication transmission distance and reliability, data transmission delay and so on. It is shown that it is feasible to use this scheme to transmit SV and GOOSE information transparent between intelligent substations. Finally, the contents and problems that need to be further studied in the process of practicality are pointed out.
