Abstract:Communication network of wide area protection may be interrupted because of severe environment or artificial damage. It is also one of the factors which affect the application of wide area protection. In order to maintain the transmission of the data on the interrupted channel, this paper designs different paths reconstructing algorithms for GOOSE and SV respectively by taking communication network of wide-area protection when heavy load as an object. Due to the importance of GOOSE and its high requirement for real-time, a single roundabout path reconstruction algorithm is proposed. As for SV whose amount of data is large, a reconstruction algorithm of shunt paths is proposed. It is the key that the available margin of bandwidth of weakest channel among the circuitous paths is considered in the algorithm. All the SV are divided into several streams according to the ratio of margin to entire bandwidth of the weakest channel, so that the balance of communication network with heavy load can be ensured after dividing. Finally, IEEE14 nodes network is built with OPNET. Delay and balance of the reconstruction strategy of circuitous communication paths are tested.
