摘　　要：通过对三个数字化变电站中远动装置与间隔层装置通信异常问题的分析,得出通信异常原因:一是远动装置与间隔层装置通信策略有缺陷;二是connect{}函数不应使用阻塞模式;三是BCM芯片的默认配置模式设置不当。通过针对性的设计优化、完善,消除了设计缺陷,提高了远动装置通信的可靠性。By analyzing the abnormal communication between the telecontrol device and the bay device in three digital substations,the reasons for the abnormal communication are obtained.Firstly,the communication coordination strategy between the telecontrol device and the bay device is defective.Secondly,the connect{}function should not use blocking mode.Thirdly,the default configuration mode of BCM chip is improper.Through targeted design optimization and improvement,the design defects are eliminated,the communication reliability of telecontrol device is improved.
