Abstract

PV as an important form of new energy, which has good prospects has been developed rapidly in recent years. However, distributed PV grid causes such as power quality, stability and reliability, also distribution Maintenance island effect will work to bring a lot of PV systems security risks. This mainly caused by random output characteristic of PV. Although the SGC issued ‘the regulations on photovoltaic power station connected to the electricity grid technology’ for the problems of photovoltaic power station connected to the grid, which is a preliminary stipulation for the safety defend of photovoltaic power station connecting to the grid, but there is not a security protection scheme specific to power grid maintenance work. In order to reduce the impact of distributed PV random access to the grid overhaul, it is necessary to set three security barriers. At the same time, to prevent isolated island effect, we need to use remote monitoring system to detect isolated island on the basis of a detailed analysis of the isolated island effect. Avoid isolated island effect on the operational safety and personal safety.
