Abstract:

Abstract:The advantages of photovoltaic power generation were introduced. The influence of the connection of photovoltaic power stations into power grid on the relay protection of power grid was analyzed. The selection of voltage class of the power grid, into which the distributed photovoltaic power stations will be connected, and the connection mode were expounded. Three solutions for connection of photovoltaic stations into power grid were put forward.
