摘要:

当前智能变电站过程层采用双网架构，IED设备的处理器同时处理双网数据，存在处理器负荷高的问题。SV采用光纤直连传输方式、存在布线复杂、IED设备光口多、成本高、装置发热量大、信息共享困难及链路无法监视等各种问题。同时GOOSE采用网络传输方式，过程层网络与光纤直连方式并存，结构不清晰问题。针对高可靠性无缝冗余协议(High Reliablity Seamless Redundant Protocol, HSR)和并行冗余协议(Parallel Redundant Protocol, PRP)的智能变电站过程层组网进行了研究，并基于该组网基础上进行了HSR和PRP的延时累加技术研究及测试。该研究为将来在国内智能变电站进行推广应用此技术提供了坚实的理论分析和测试结果参考数据。

Abstract:

The current smart substation process layer adopts dual-network architecture and IED processor processes dual-network data simultaneously, which causes the problem of high processor load. SV uses the mode of directly connected through optical fiber transmission, in which exists complex wiring, multi port of IED equipment, high cost, high heating of equipment, difficulties in information sharing, and the issues that links can not be monitored, etc. At the same time, GOOSE adopts network transmission mode, the process layer network and optical fiber connection mode coexist, so the structure is not clear. The process network of smart substation of HSR (High Reliablity Seamless Redundant Protocol) and PRP (Parallel Redundant Protocol) is studied, and the delay accumulation technology of HSR and PRP is studied and tested on the basis of the network. It provides a solid theoretical analysis and test result reference data for the future popularization and application of smart substation in China. This work is supported by Science and Technology Project of China Southern Power Grid (No. ZDKJQQ00000016).

Key words: smart substation delay accumulation HSR PRP process layer
