摘要
Method for detecting an isolated operation of power generation plants (5), which are set up for generating electrical energy and coupled to a grid (1) in the feed mode, wherein the power generating plant (5) operates island operation relative to the grid (1), if no energy exchange between Energy generation system (5) and interconnected network (1), comprising the steps: - Recording the time profile of the frequency of the mains voltage, which is present at the connection area of the power generation plant (5) with the interconnected network (1), and - Evaluating the time course of the frequency Mains voltage for detecting an island operation, characterized in that the evaluation of the time course of the frequency of the mains voltage, an analysis of the statistical properties of the noise component of the time profile of the frequency of the mains voltage and the detection of island operation based on recognized in the analysis statistical identification features n includes.
