Filtering Methods of GOOSE Messages on Process Level in Smart Substations

Abstract:

How to eliminate the influence of network storm produced by GOOSE messages on equipment of process level is an important task to smart substation. Both valid and invalid GOOSE messages transmitted in process levelare likely to lead to the network storm. At first, the reason that causes network storm in smart substation is analyzed in this paper. Then three kinds of filtering methods are given: Real-time matching method with creating a buffer, the method of cutting off the storm network and abnormal packets discarded method, In the end, the first method is verified on the intelligent terminal.
