Current Reckoning Method to Identify Overlapping Bad Data and Branch State in State Estimation
The current reckoning method is modeled by alternating current branch model,at the same time,the current reckoning network model is established1.Based on the current measurements,the link reckoning technology is used to obtain the reckoning current,and then achieve the identification,current difference,to mine its identification characteristics in the presence of undesirable measurements in state estimation.After that,the branch state can be judged based on the current information which excludes the bad data interference,thus obtaining the actual operation structure of the network.In this paper,the current reckoning method is used to modify the current measurement set,and the branch state change of the system is judged,the coexistence of bad data and branch state change is further analyzed.
