Application of Fuzzy Logic to Electrical Protection Devices

Abstract

Abstract The amount of electricity used is followed by the magnitude of the risk of disasters caused by power disruptions. In general, PLN as the manager of electricity distribution has provided standard protection for users, but it has not provided good protection from disasters due to disturbances, because in general the protection is specific to one type of disturbance, and the cause of the disturbance cannot be known through protection devices provided. Therefore we need a smarter electrical protection device by applying fuzzy logic to the protection device. Fuzzy on this protection device aims as a decision support system to show the condition of the electricity network based on the parameters of voltage, current, and temperature of the cable. The results of fuzzy logic in the form of a hazard level with a range of 1-10 which is divided into 3 status states, namely safe, alert, and hazardous, which in danger conditions the protective device will cut off the electricity so as not to damage electronic devices. Besides that, from the results of fuzzification, the parameters measured can be known to cause interference.
