Firstly, according to the operating features of tie-line, the key decision factors deciding the operating mode of tie-line are extracted, a rule base of definition of tie-line operating modes is established and a discriminative model of tie-line operating modes is proposed; then during the design of the interface with data of EMS, the flow sheet for tie-line power flow monitoring is optimized; finally, an on-line monitoring system for tie-line power flow, which possesses the functions such as definition of tie-line operating mode rule base, transmission line operating mode monitoring and tie-line power flow monitoring, is developed, and the developed system can provide report forms of statistical analysis on transfinite record of tie-line power flow.
