新一代分布式母线保护装置

A new generation of distributed busbar protection device

新一代分布式母线保护装置采用组网通信方式,减少了主机光口数量,降低了装置功耗,具备冗余通信能力,提高了装置稳定性及可靠性。通过设置子机发送报文优先级,并采用乒乓对时方案实现子机采样同步,基于面向间隔对象的母线保护设计方法,子机将本间隔的母线拓扑连接关系上送给主机,主机自动完成母线主接线构建,实现了自适应主接线功能。最后介绍采用新一代分布式母线保护装置的变电站改扩建方案,减少了改扩建工作量,降低了工作风险,提高了工作效率。

The new generation of distributed busbar protection device adopts networking communication mode,which reduces the number of optical ports of master device and the power consumption of the master device.It has redundancy communication capability,and the stability and reliability of the device are improved.By setting the priority of messages and using ping-pong timing scheme,the sampling synchronization of slave device is realized.Based on the generic definition of object oriented model,the slave device sends the bus topological to the master device,and the master device automatically completes the single line construction,realizing the self-adaptive single line function.The reconstruction and expansion scheme of substation with new generation distributed busbar protection device is introduced,which reduces the workload of reconstruction and expansion,reduces the risk of work and improves the work efficiency.
