Abstract This paper introduces a medium-voltage busbar differential protection technology based on high availability seamless redundancy (HSR) network communication, which adopts single bay combination protection device to complete their own information collection and sends the information required by bus differential protection to busbar differential protection device through the HSR network. After busbar differential protection acting, tripping instructions are also sent to each single bay combination protection device through the HSR network without adding CT or wiring. The busbar differential protection device is small in size and light in weight, which can be directly installed in the switchgear. The test shows that it can realize the busbar differential protection function of 30 bays in a ring network.

Key words： high-availability seamless redundancy (HSR) ring network medium-voltage busbar differential protection differential current synchronization
