The identification problem of double-circuit transmissions state estimation based on the current reckoning method

The current reckoning method is based on the system operation network and modeling to achieve current reckoning network model, using the link reckoning technique and branch current measurement to identification and calculation. Analysis current difference identification features, to identify bad data, then correct the bad data, on the basis of the revised branch current to determine the state changes of branches. The research based on current reckoning method in double-circuit transmissions to discriminate bad measurement and determine the state of branch opening and closing is recorded in this paper.
