Abstrac

Although the distributed generation is bringing many benefits to the grid, its operation is also getting even more complicated due to the many loads and generators involved into it. One important issue that must be detected as fast as possible to avoid any damage for the grid and/or the loads connected is the islanding. The paper analyses the modelling of a relay based in a passive method of islanding detection for the software ATPDraw, which is current unavailable. So we focussed in a model based in the frequency, which the rate of change of frequency relay - ROCOF - was chosen. The results show that the relay was successful to detect the islanding under various circumstances and is obeying the requisites established by the IEEE 1547.
