Investigation on the Electric Field Inverse Problem of HV Transmission Lines and Discussion on Its AppliAbstract
The electric field inverse problem of high voltage transmission lines is investigated in this paper. Firstly the equations for the electric field forward problem of transmission lines were formulated, then equations for the inverse problem were formulated according to the forward problem and the least square theory. A method to solve the inverse problem is presented in the paper, in which the global regularization was used to process the ill-posed characteristic of the inverse problem. The Damped Gauss-Newton iterative method was used to search the optimum solution. A 500kV double-circuit transmission line was taken as an example for the calculations of the inverse problem. The inverse problems for different situations were calculated, including the situation when the transmission lines were in normal operation, and the situation when the transmission lines were in faulty state. The solutions to the inverse problem with and without regularization were compared in the paper, and the results indicated that the global regularization can effectively eliminate the ill-pose of the inverse problem. The electric field inverse problem can be used to confirm the electrification state of the ultra high voltage transmission lines, and also can be used in the environmental assessment tests to reduce the measurement workload.
