In this research, traveling wave (high frequency) signature based protection scheme is proposed for future distribution systems. Simulations are performed under different transient scenarios to provide insight into the high frequency signatures to show the traveling wave behavior. Finally, this paper ...
The DSLS-1 system uses the voltage traveling wave when the transmission line fails, including high positive grounding and lightning strike, to achieve fault location, that is, through 5MHz high-speed sampling, GPS high-precision time signal sampling bus...
According to the actual site condition, a non-contact electromagnetic field sensor is arranged in a transformer substation to acquire transient voltage and current traveling wave, a power distribution transformer arranged on the tail end of the circuit transmits voltage-variable traveling wave to solve...

Based on the relationship of electromagnetic coupling among phase wires and the fact of traveling wave refraction from a faulty line into non-faulty lines through buses, the paper presents a new approach to identify the faulty line with single-phase-to-grounding fault in distribution systems without...
Analytical thermal traveling-wave distribution in biological tissues through a bio-heat transfer (BHT) model with linear/quadratic temperature-dependent blood perfusion is discussed in this paper. Using the extended generalized Riccati equation mapping m
The second row shows the difference between the two, focusing on positive values, i.e., the traveling-wave events in the data that occur more often than predicted by the null distribution. The proportion of significant BW and FW waves are shown in red and blue, respectively....
In order to demonstrate the traveling wave pattern, we compute the spatiotemporal correlation function C (δx, δy, δt) of the polarity field (see Spatiotemporal correlation in Sec. Methods). Figure 3(B) shows C (δx, δy, δt) for three values of δt = 0, 2 and 4. We ...
a针对远距离输配电线路,其传输的距离越大,行波由始端传播至终端所需的时间就越长 Loses the distribution line in view of the long-distance range, its transmission distance is bigger, the traveling wave which needs to the terminal is longer by the beginning end dissemination the time [translate] ...
