Research on Line Protection of Distributed Power Generation Connected to Distribution Network
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.
