基于对等通信模式的新型母线保护装置
摘要：
本实用新型涉及母线保护系统。基于对等通信模式的新型母线保护装置，包括一母线保护装置主体、区内继电保护设备(IED)、区外继电保护设备(IED)，区内继电保护设备、区外继电保护设备均与母线保护装置主体之间对等通信连接。本实用新型允许为与母线连接的每条进线和出线上的断路器智能终端上设置方向判别功能，母线保护装置主体通过接受各智能终端上传的GOOSE信息来判别区内和区外故障。
摘要（英）：

The utility model relates to a bus protecting system. A novel bus protecting device based on a peer communication mode includes a bus protecting device body, an internal relay protection device (IED) and an external relay protection device (IED). The internal relay protection device and the external relay protection device are both in peer-communicational connection with the bus protecting device body. According to the utility model, a direction distinguishing function is allowed to arrange for circuit breaker intelligent terminals on all inlet wires and outgoing wires connected with the bus and the bus protecting device body distinguishes internal faults from external faults through receiving GOOSE information uploaded by the intelligent terminals.
