Method of local characteristics for calculating electric field and ion current of HVDC transmission lines with transverse wind

Fast Corona Discharge Assessment Using FDM integrated With Full Multigrid Method in HVDC Transmission Lines Considering Wind Impact

“…The FDM is implemented to solve the continuity equation in the case of wind and without wind conditions. Combining (2) and 3should result in:…”

“…With the huge increase in power transmitted over long distances, high voltage direct current (HVDC) transmission has become emulative, and many HVDC transmission lines have been built around the world [1][2]. HVDC transmission uses the ground as a return path, requiring simpler towers and therefore lower net costs.…”

Ion‐flow field calculation of HVDC overhead lines using a high‐order stabilisation technique based on Petrov–Galerkin method

“…The potential on Γ a is set as the space-charge-free one. This can be done because the electric field due to space charges is negligible there, which has been proved to be proper and widely used [1,[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23].…”

“…Recently, this type of methods has been further developed to eliminate the error due to the Deutsch assumption [11][12][13]. In order to overcome the instability and guarantee the conservation law in strong-wind condition, the method of local characteristics (Local-MOC) is proposed in [12]. However, the further extension of Local-MOC to time-domain problem is somewhat difficult.…”

Calculation of Surface Electric Fields on the Lighting Conductors near HVDC Transmission Lines

“…The flux tracing method (FTM) is a kind simplified ion flow field calculation method based on the Deutsch assumption [14][15][16][17]. This method is recommended in the designing standards of overhead transmission lines, and widely used in the engineering practice [18][19][20][21][22].…”
