With the gradual increase of the penetration rate of distributed photovoltaic generation in the distribution network and in case of of disconnecting the system power supplyduring power outage maintenance of distribution network lines with distributed photovoltaic generation，the possibility of distributed photovoltaic generation and loads forming an island system increases，which poses a serious threat to the safety of maintenance staff. In response to the above problems，the feasibility of such two measures as access to the load and simulation of short-circuit faults at the line incoming end which can be taken by the maintenance staff is analyzedfrom the perspective of maintenance staff. Access to the capacitive load by the maintenance staff at the line incoming end can reduce the cost，reliably make distributed photovoltaic generation operating in islands in the line out of operation，thus ensuring thesafety of maintenance personnel.
