摘要
以某220kV变电站为例,结合该变电站内各电压等级的短路电流水平、系统中性点接地方式及保护配置存在差异的特点,将变电站内接地系统分区建设,实现接地系统的精细化设计。将传统接地系统设计方案与优化后的设计方案进行对比,结果表明优化后的设计方案能够节省接地材料、降低投资成本。
Taking a 220 kV substation as an example,with the differences among the short-circuit current levels,system neutral piont treatment and the protection configurating of 220 kV substation,partition constructed on the grounding system,realize the fine design of grounding system,saving grounding material,saving the cost of investment.
