| Abstract: | Based on the theory of grounding grid topology simplification , electric network theory and matrix theory are used to establish the intrinsic grounding grid fault diagnosis equation. The establishment of diagnosis mathematical model with minimum energy theorem successfully solves the problem of morbid equation. Results of calculation and analysis of practical examples show that the propoesed methed is feasible. |
