【 摘 要 】

In this study, it is emphasized that simulation of the avoidance of unnecessary energy cuts in a sample electricity distribution network. The electricity cut-off costs can be decreased by ensuring that relay coordination end only at the source of the fault from the point of failure. Over currents are calculated and the sample network is simulated in the LabVIEW environment. The parameters of delayed overcurrent trip setting (I>), instantaneous overcurrent trip setting (I>> ), delayed ground overcurrent trip setting (Io>), instantaneous ground current trip setting (Io>>) are set according to a specific logic in relay coordination. As a result, you can get an idea about how much profit can be made by doing the relay coordination correctly and the amount of unnecessarily avoided energy. It is aimed with the application of this simulation in the real field that electrically operated materials of the people, who are unnecessarily energy-consuming, have less damage and that the energy-selling company loses less money.
