基于 FPGA 的 GOOSE 通信系统

摘要

GOOSE作为IEC 61850中的一个亮点，在电力系统各领域的作用变得日益重要。 GOOSE属于GSE两种报文结构中的一种，它主要用于传输变电站中的跳闸、闭锁等状态量信息和开关信息。如何实现GOOSE的实时及可靠传输，显得至关重要。针对GOOSE报文的可靠性和实时性，提出了一种基于FPGA技术的单CPU构架模式的GOOSE报文通信系统，并介绍了其可靠性与实时性功能的实现。最后，通过实验验证了装置传输的可靠性，并对装置的传输延时进行了检测。%The role of GOOSE which is used in various fields of power system has become increasingly important as a shining point in IEC 61850 protocol .GOOSE is one of the GSE′s two structures of message and it is mainly used in the information of tripping , blocking state and switches in the transmission substation .It is crucial to realize the real-time and reliable transmission of GOOSE .Aiming at these features , this paper proposes a single CPU architecture model of GOOSE communication system based on FPGA technology , and introduces the realization of its function of real-time and reliability .Finally , the reliability of transmission of the gear is verified by experiments , and its trans-mission delay is tested .
