Abstract 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.

Key words： new generation distributed busbar protection self-adaptive
