摘要
综述了10 kV柴油发电机组中性点接地的各种方式,对10 kV柴油发电机组中性点接地电阻值、单相接地故障的短路电流值和保护定值进行了计算,并结合上海中心项目提出10 kV柴油发电机组运行策略,以供其他类似项目参考。
This paper summarized the various modes of neutral point grounding of 10 kV diesel generator set. The resistance value of neutral point grounding,short-circuit current value and protection setting value of 10 kV diesel generator set were calculated. The operation strategy of 10 kV diesel generator was proposed according to Shanghai Tower project. It could provide references for similar projects.
