| 摘 要： | 对冲江河110 kV水电站地网设计不合理,接地电阻严重超标的情况进行了综合分析;通过对该水电站周边地形、地质、土壤电阻率等因素进行了测试和调查之后,结合相关规程及水电站的实际情况提出了通过铺设水下接地网来对水电站接地进行改造的改造方案;计算分析结果表明该方案能够经济有效的解决水电站接地电阻过高的问题。当水下接地网铺设完成后,我们对其接地电阻值进行了测量。最后通对水下接地网接地电阻测量值与计算值的比较,验证了水下接地网解析算法的准确性。

| Abstract: | The situation that the unreasonable design of grounding reconstruction in the hydropower station,and grounding resistance greatly exceeds the specified value are analyzed comprehensively.Through test and investigation on the factors such as the geography,geology and soil resistivity,and combined with regulations and actual conditions the program of underwater grounding grid extension in a reservoir is proposed to reduce the target value by this effective method.When the program is completed,the grounding resistance is measured.Finally,the measurement is compared with the calculated value of underwater grounding resistance,the accuracy of the analytical algorithm on the underwater ground resistance is verified. |
