In this paper discussed digital overcurrent protection system fuzzy logic on plant systems or Micro Hydro Power Plants with fuzzy logic approach to the identification of the signal changes due to interference overcurrent short circuit the lifeboat station on the system. A digital overcurrent protection with a fuzzy logic-based method and the rules set if-then, fuzzification and defazzification which has 2 inputs are crisp and delta error and error the actual fault current has a crisp output 1 to input changes in current to drive the relay breaker. This system consists of a hardware system with microcontroller (mc) ATMega8535 and other series as well as software that helps in the protection process performance Delpi 7 computer using fuzzy logic and program using C language and dicompel with CodeVisionAVR software and uploaded to the microcontroller using ponyprog2000 ATMega8535. The success of a prototype digital overcurrent protection system was tested on a fuzzy logic system voltage of 220 volts with a simple system technique burdened beyond any current settings and calculated over a given working time protection relay. After testing and calculations, then the inverse Characteristics of digital protection between the current disruption to the working time protection can be envisaged that a larger fault current less time working to secure protection from interference generating systems.
