摘要

环网通信是就地化保护的一个重要技术特点，其可靠性直接影响就地化保护的性能。文中介绍了就地化保护环网通信的通信机制和典型实现架构，分析了通信中断、误码、延时补偿异常、网络风暴等典型通信异常对就地化保护的影响。在此基础上，提出了基于双环双向数据判别的通信中断、误码、延时补偿异常处理策略以及基于报文识别和过滤的网络风暴处理策略，并给出了具体的实现方案。最后通过试验证明了处理策略的可行性。

Abstract

Ring network communication is an important technical feature of outdoor installation protection

and its reliability directly affects the performance of outdoor installation protection. This paper introduces the communication mechanism and typical implementation framework of outdoor installation protection ring network communication

and analyses the influence of typical communication exceptions such as communication interruption

code error

delay compensation anomaly and network storm on outdoor installation protection. On this basis

handling strategy for communication interrupt

error code

and delay compensation based on double-loop bidirectional data discrimination

network storm handling strategy based on message recognition and filtering are proposed

and the specific implementation scheme is given. Finally

the feasibility and effectiveness of the handling strategy are verified by experiments.
