A sub-area fault diagnosis method for a transformer station grounding network aims at a given grounding network design topology structure and performs layered reduction on the grounding network design topology structure. The sub-area fault diagnosis method comprises the steps of calculating nominal value parameters of branch resistors according to original designing data, selecting a common node, generating an associated matrix A and a branched admittance matrix Y; building a simulated circuit model, applying a DC source excitation I0 between nodes i and j which are selected in the circuit; testing the voltage Uij of a selected accessible node, and obtaining a port resistance Rij between the nodes i and j; after the grounding network fails and the measured port resistance between the nodes i and j is changed to R'ij, comparing the measured port resistance with the accessible port resistance in the normal state of the grounding network, and obtaining a port resistance difference vector deltaRij ...

The invention provides a ground grid fault diagnosis method based on a self-adaptive particle swarm optimization algorithm. A fault diagnosis equation is established according to a node voltage analytical method in an electric network theory, then a target optimization function is obtained according to a minimum energy principle, the problem of ground grid fault diagnosis is converted into the problem of target optimization with constraint conditions, then the self-adaptive particle swarm optimization algorithm is adopted to solve the optimization problem, and a diagnosis result is obtained. In the ground grid fault diagnosis method based on the self-adaptive particle swarm optimization algorithm in the invention, through establishing a mathematical model for ground grid fault diagnosis, and using the optimization target function, the ill-condition degree of the diagnosis equation is lowered, and the global optimization capability of the self-adaptive particle swarm optimization algorithm ...
