The protection of HVDC system is an important topic for stable transmission. When fault happens, DC breaker opens the circuit electronically unlike AC breaker, therefore, its operation is very fast. Besides that, it is also equally important to design a fast fault detection method. This paper investigates the application of Short Time Fourier Transform (STFT) to not only detect but also differentiate...
HVDC system has become practically mature over the years but it is still met with some protection issues which should be discussed, for example, the circuit breaker (CB) should be selective to not trip if the transient is temporary, such as overcurrent due to load change. This paper addresses the problem with identifying the type of faults in a HVDC system using wavelet transform (WT). The wavelet...
