Design and Development of Distance Protection Scheme for Wind Power Distributed Generation
2018
In recent years, the growth of Renewable Energy Distributed Generation is increased by using Renewable Sources such as solar, wind etc. The wind power distributed generation produces clean and pollution free electrical energy. The Protection Coordination between the Distributed Generation (DG) and conventional power system is needed for reliable operation. The intention of this work is to manifest a suitable protection scheme for the interconnected power system with wind power Distributed Generation system. This paper evolves a protection scheme to refine the tripping behavior of relay and to ensure the protection coordination between conventional power system and wind power distributed generation system. The interconnected power system is considered with normal and fault condition (Line to Line Fault) and the faulted zone is detected based on the impedance calculation method. The interconnected power system with distance protection is manifested in the MATLAB R2014a/Simulink environment and simulation results are analyzed. The length of transmission line and size of DG does not affect the relay characteristics.
