Research Of Mapreduce Architecture On Busbar Protection

In order to solve the poor performance of busbar protection for outdoor installation, a distributed design method based on MapReduce architecture is introduced. The distributed busbar protection sub-machine which connects with HSR ring is divided into the scheduling node and the task node. The differential protection module of busbar protection is allocated some nodes to compute and merge according to the number of sub-machines, then the backup protection related to each sub-machine is assigned to the corresponding sub-machine and some redundant computing sub-machines, this design completes the busbar protection distributed computation and logical judgement, and the protection trip uses the "action three take two" logic. Through RIDS test, this design has proven to be reliable and improve the available resources and performance of the busbar protection.
