A Solution of Transmission Differential Protection Service Based on the Customized ASON Technology

In order to improve the reliability of the transmission line differential protection communication channel, according to the principle and communication channel parameters of differential protection requirements, this paper proposes a solution of the transmission differential protection service based oil the customized ASON technology. The solution improves the existing ASON network self-healing mechanism in terms of the channel time-delay management and the channel switching order, and achieves the self recovery ability of differential protection services under the case of multi faults. The results of the theoretical analysis and practical tests show that the performance of the solution can meet the needs of the differential protection services channel intelligent self- healing, and can act as a dedicated ASON network product for electric power and provide a reference for electric power communication network construction and operation.
