MMC-SST input-level control strategy considering power quality optimization

open access: yes电力工程技术, 2022
The surge of negative sequence component of current affects the waveform quality of grid side current and endangers the normal operation of the system when the three-phase voltage of solid state transformer (SST) in the distribution network is unbalanced

Criterion of single-phase fault nature of AC line considering the influence of commutation failure

open access: yes电力工程技术, 2022
The amplitude of AC line current at the inverter side is affected by DC commutation failure and fluctuates for a short time after single-phase trip.The fluctuation range increases with the increase of the number of DC commutation failures,resulting in ...

Grid Diagrams and Legendrian Lens Space Links [PDF]

open access: yes, 2008
Grid diagrams encode useful geometric information about knots in S^3. In particular, they can be used to combinatorially define the knot Floer homology of a knot K in S^3, and they have a straightforward connection to Legendrian representatives of K in ...
