摘要： A method for correcting protection settings in a relay provided in a micro-grid between a grid-connected settings group when the micro-grid is electrically coupled to a utility grid and an islanded settings group when the micro-grid is disconnected from the utility grid. The method determines whether the micro-grid is connected to the utility grid and what settings group the relay is in. The method changes the settings group of the relay to the grid-connected settings group if a time that the micro-grid is connected to the utility grid and the relay is in the islanded settings group exceeds a predetermined time and changes the settings group of the relay to the islanded settings group if the time that the micro-grid is not connected to the utility grid and the relay is in the grid-connected settings group exceeds the predetermined time.
