Electric Power Research Institute, Yubei District, Chongqing 401123, China) ABSTRACT: With the development of smart grid, the demand lines were deduced. The three identification variables were for real-time monitoring of the electric parameters (e.g. current) pared to only one in the inverse calculation process, which along the overhead transmission lines is increasing. However, greatly reduce the computation complexity of the inverse there are many difficulties in the installation of transformers in problem solving. Finally, the simulation analyses verify the
