Abstract
A method, an apparatus, and a system for monitoring an islanding electricity generation unit are provided. The method includes determining an islanding electricity generation unit in a renewable energy station on the basis of collected electrical capacity at critical electrical nodes of the renewable energy station, and controlling a switch device corresponding to the determined islanding electricity generation unit to sever connection between the electricity generation unit and a collector line. The critical electrical nodes include nodes that have a collecting effect on grid-connected current of the electricity generation units of the renewable energy station, and each collector line being constructed to collect grid-connected current from at least one electricity generation unit and input same into a main transformer of the renewable energy station.
