求翻译：本文对冲江河水电站接地电阻严重超标的情况进行了综合分析，通过对该水电站周围环境以及土壤电阻率等因素进行了测试和调查，结合相关规程及水电站的实际情况提出了改造方案。针对山区水电站易受雷击，而山区的土壤电阻率偏高，水电站接地网的接地电阻难以降低，提出了在山区高土壤电阻率地区的水电站接地网改造中利用站内地网和附近水库设置水下地网的方法相综合的方法来降低接地电阻值。通过计算分析比较了两种具体的实施方案，选择了一种比较科学有效的方案在冲江河水电站实施了接地网改造，改造后的实测结果表明该方案正确、有效可供借鉴，同时验证了水下接地网解析算法的准确性。是什么意思？

Excessive hedge River hydropower station grounding resistance seriously this article a comprehensive analysis of the situation, the hydropower station by the surrounding environment and tested factors such as soil resistivity and investigation, combined with the point and the actual situation of hydropower station made a reconstruction plan. For hydropower station in mountainous areas vulnerable to lightning, mountains higher soil resistivity, difficult to reduce grounding resistance of grounding grid of hydropower station, offered a high soil resistivity area in mountain area of grounding grid reconstruction used station of hydropower station under water reservoir near the Mainland network and network with the method of integrated approach to reduce grounding resistance value. Through computational analysis and comparison of two specific implementation programmes, selecting a more scientific and effective grounding network improvement programme was introduced in Red River hydropower station, after test results showed that the plan to transform the correct and valid for reference and verify the accuracy of underwater ground grid resolution algorithm.
