Wavelet Based Multi-Terminal Transmission Line Protection with MicroGrid
Authors: , ,
Abstract: This paper introduces a novel protection scheme for protecting multi-terminal transmission system combined with microgrid comprises of wind, solar, fuel cell energy sources.Microgrids provide clear economic and environmental benefits for end-customers, utilities and society. However, their implementation poses great technical challenges, such as a protection of microgrid and transmission system. Protection must respond to both utility grid and microgrid faults. The major challenges are a protection system for microgrid which must respond to main grid as well as microgrid faults. After the microgrid is model is developed and it is connected to an equivalent multi terminal transmission system. Wavelet Multi Resolution Analysis is used for detection, classification and location of faults on multi terminal transmission system as well as microgrid resources.The proposed algorithm is tested and it is proved for the detection, classification of faults on transmission system with microgrid which is almost independent of fault impedance, fault inception angle and fault distance of feeder line.
