The short circuit disturbance is ocasionally can't be avoided by a system of power distribution which can be caused by both of internal and external factors of the systems. The disturbance can cause some damages to many distribution equipments or electrical loads if the disturbance not be isolated by a protection device. One of the major protection devices in distribution power system is overcurrent relay. Determining of setting for the relay depending by how many relays at the network which must related to each other so all of the relays can be well coordinated. There is no coordinated protection device yet in the distribution power system in Pusdiklat Migas Cepu and they still using some conventional protection devices like fuse which must be replaced by another one when it melted. For that, the research about coordination planning analysis of overcurrent relay in the distribution power system in Pusdiklat Migas Cepu is necessary. Research began by collecting all of data that required for analysis. Then create a single line diagram using ETAP Power Station 12.6 software. Then decide the point where the overcurrent relay is and calculate the value of short circuit at the nearest point of the relay. When all of the data are completed, then calculate the setting of the relays and do the analysis and illustrate a coordination curve. The result of the research shows that any data that required for determining the overcurrent relay setting. The farther location of the relays from generator, the setting of time and current must be lower than the relay setting behind them.
