ABSTRACT: IEC 60870-5-101 telecontrol protocol adopts FT1.2 frame format, link circuit transmission rules and enhance performance architecture model. Here, the data transmission
features in distribution automation (DA) system are analyzed, the application of IEC 60870-5-101 telecontrol protocol in data transmission process of DA system is dissertated, in addition the design philosophy of protocol conversion program and the network transmission process of telecontrol information are described. The concrete analysis on problems occurred in practical application, such as the priority of data transmission, general interrogation and the off-limit value setting in remote measuring, are presented and corresponding solutions are proposed.
