Computer modeling with the EMTP code has been applied to several configurations and earthing practices in use in various countries to show the effect of any differences in the dispersion (sharing) of a lightning stroke current among the available paths for the earth-seeking lightning current. Simplifying assumptions have been made to some details of the configurations to focus on the main diffe...

In this paper, EMTP/ATP simulation environment is used to model the Rogowski coil for partial discharge (PD) monitoring due to leaning trees on the covered-conductor (CC) overhead distribution lines. The simulations are performed to obtain the Rogowski coil response at different lengths of the CC line and the results are compared with those obtained from the laboratory measurements. The results...

The mathematical interpretation of an electric arc is practically very difficult by virtue of its extremely accidental character. But on the other side, the mathematical formulation course of the electric arc is possible with transfer to the area of the mathematical modeling for specific conditions. Limits of influences of the electric arc are possible to determine with using results from mathe...

Aiming at the problem of low redundancy in structure cascaded H-bridge STATCOM. This paper studies and designs a STATCOM device based on STM32 distributed control. The article introduces basic topology realization principle control system. turn-on turn-off time MOSFET each is calculated by using law minimum harmonics, realize output fitted sine wave. A simulation model 12H bridge cascade built ...
