Abstract
A new model considering corrosion property for grounding grids diagnosis is proposed, which provides reference solutions of ambiguous branches. The constraint total least square method based on singular value decomposition is adopted to improve the effectiveness of grounding grids' diagnosis algorithm. The improvement can weaken the influence of the model's error, which results from the differences between design paper and actual grid. Its influence on touch and step voltages caused by the interior resistance of conductors is taken into account. Simulation results show the validity of this approach.关键词
