With the development of ultra high voltage AC and DC power system, fault current of power plants, substations and convertor station are great than before. Larger grounding grids are needed to meet the safety regulation. Grounding grids usually located in horizon multilayer or vertical multilayer soil structure which parameters such as thickness, resistivity of each layer can be estimated. This paper...
At present, how to decrease the resistance of ground grids to safety regulation is very important in grounding programme, using earthing module is one of the effective methods. In this paper, the ingredient and the principle of resistance reducing of earthing module were introduced firstly. Then, set up the model of ground grids and simulated them by grounding software under different situations....
