摘要
可再生能源的发展促进了DG的发展,但考虑到可再生能源的随机波动性,大规模接入配电网会导致电压下降,大量电力电子设备更是会导致谐波污染,因此,保证DG接入配电网的安全性十分重要.文章介绍了IBDG的故障特性,阐述了IBDG单相接地故障的影响,并从不同方面对直流电网线路进行保护,以期为相关人员提供参考.
Abstract
The development of renewable energy has promoted the development of DG,but considering the random fluctuations of renewable energy,large-scale access to the distribution network will lead to voltage drops,and a large number of power electronic devices will cause harmonic pollution.Therefore,ensuring the safety of DG access to the distribution network is very important.The article introduces the fault characteristics of IBDG,elaborates on the impact of IBDG single-phase grounding faults,and provides protection for DC power grid lines from different aspects,in order to provide reference for relevant personnel.
