    Abstract: Renewable energy resources are being used to overcome energy shortage. From the point of view of energy management the interconnectivity of electric utility with renewable energy resources is difficult. Renewable energy resources need to be managed with electric utility. A Smart Energy Management System (SEMS) is designed and developed for monitori... Show More

    Abstract: This paper presents a new approach to protect the transmission line by a design and implementation of distance relay using Fuzzy logic module. The proposed module uses sample of voltage and current signals to calculate line impedance (ZL). Simulation studies are performed and influence of changing system parameters such as type of faults like singl... Show More
