6kV 中性点不接地系统发生单相接地故障保护优化

摘要

With the development of chemical business,the requirements of stability and reliability of power system also increase.In order to ensure the process and conduct of all production sets,we discuss the optimization of 6kV isolated neutral system in case of single -phase grounding fault.%随着化工区业务的不断发展，对生产装置供电系统的稳定性和可靠性的要求也随之提高。为使化工区各生产装置处于有序平稳的运行环境，保证连续生产装置的可靠运行。针对6kV 中性点不接地系统发生单相接地故障时，提出故障保护优化，通过保护优化后保证供电系统的稳定性和可靠性。
