| 摘 要： | 为提高继电保护装置的光纤通道故障监测能力和定位能力,尝试将IEEE-C37.94光接口标准应用到继电保护装置,并研究该标准应用到继电保护装置中的优势及局限性。通过解读IEEE-C37.94光接口标准帧格式的协议,结合国内继电保护装置的光纤传输要求,验证该标准可以允许不同厂家的保护设备与数字复接接口设备在光接口处能够互通,并且对不同链路的通信故障能够有效定位。但也存在传输带宽不高问题,宽松的校验措施也给其应用于继电保护设备带来了一些局限性。实际应用情况表明,IEEE-C37.94标准应用于继电保护设备是可行的。

| Abstract: | In order to improve the surveillance and fault location of communication in power supply system, IEEE - C37. 94 has been applied in relays. The advantage and limitation haa also been found from the application. From analysis of the IEEE - C37. 94 frame characteristic and transmission requirement in relays, it is proved that different relays and digital interfaces can be communicated with each other which supports IEEE - C37.94 and it is efficient for fault location of communication. However, the limitation of low bandwidth and loose examination has been confirmed. It is feasible for application of IEEE - C37.94 in relay protection. |
