متن کاملAn Intelligent Protection Method for Multi-terminal DC Microgrids Using On-line Phaselet, Mathematical Morphology, and Fuzzy Inference Systems
In this paper, a new method for fault detection, location, and classification in multi-terminal DC microgrid (MTDC) is proposed. MTDC grids have expanded due to some issues such as the expansion of DC resources, loads, and aims to increase power quality. Diagnosing the types and location of faults is important to continue the service and prevent further outages. In this method, a circuit kit is...
متن کاملFault Location in Extra Long HVdc Transmission Lines using Continuous Wavelet Transform
In this paper, fault location accuracies in a 2400 km long overhead HVdc line and 300km long underground cable HVdc line using the two-terminal travelling wave method are investigated. The paper proposes to use continuous wavelet transform for detecting the arrival time of travelling waves, and shows that it provides better accuracy when compared with the commonly used discrete wavelet transfor...
