This paper proposes a solution of inverse problems for grounding grids. The grounding grid determines the safe and reliable running of substation, The study on inverse problem of grounding grid will provide an effective means for its state evaluation. The grounding grids model is half homogeneous space model, these problems are usually underdetermined due to the lack of enough data to contain a unique solution. In this paper, we present a method for the solution of underdetermined inverse problems. We present a general adjoint state formulation which can improve the calculation speed of sensitivity matrices.
