| 摘要: |
| 针对传统母线保护运维难度大、可靠性低等问题，通过比对基于环网通信的无主分布式和有主分布式母线保护各自特点，提出了基于冗余通信的就地化环网有主分布式母线保护解决方案。研究了以主机内部时钟作为同步对时源的采样同步方法，并提出了分布式系统身份拓扑定位技术，实现保护功能不依赖外部时钟、保护子机免配置和即插即用。最后结合分布式母线保护环网数据流大小，对IEC61850-9-2和GOOSE帧格式报文进行了适用性分析，提出了满足百兆口带宽和传输延时要求的新环网通信帧格式。通过现场运行检验，验证了该技术方案的可行性。 |

| Abstract: |
| In view of the problems of traditional bus protection, such as low reliability and difficulty in operation and maintenance, by comparing the characteristics of distributed bus protection with host and the protection without host, a solution of distributed local bus protection with host based on redundant ring network communication is proposed. A sampling synchronization method using host internal clock as synchronization source is studied and an identity topology location technology for distributed system is proposed, which can achieve the protection function independent of the external clock and the free configuration and plug and play. Finally, the applicability of IEC 61850-9-2 and GOOSE frame format message is analyzed according to the size of data flow in distributed bus protection ring network, a new communication frame format is proposed which can meet the requirements of bandwidth and transmission delay in using 100 M port. The feasibility of the technical scheme is verified by the pilot running in substation.
