Embodiment 1
[0016] Embodiment 1, with reference to Figure 1-2 , Embodiment 1 takes a 110kV substation in Anqing, Anhui as an example:
[0017] (1) Initial conditions of substation grounding system
[0018] 1) The measured value of soil resistivity and geological conditions,
[0019] The substation is located in the Anqing area. The size of the station area is 48m×81.5m. The measured value of the soil resistivity at the location is relatively high, as shown in Table 1. According to the survey professional "Geotechnical Engineering Survey Report", the foundation rock and soil of this station are 0.5m~4.2 m is silty clay, and the buried depth of groundwater at first sight is 3.5~4.5m.
[0020] Table 1
[0021]
[0022] 2) The initial parameters of the horizontal grounding grid are shown in Table 2, and the maximum value of the calculated grounding current is 3.43kA.
