In order to avoid excessive adjustment of power grid operation mode and to ensure the reliability of power sup-ply,series reactor will be considered to be used in more and more short-circuit current tension power grid.The study on design method of 500 kV series reactor will be of great significance for the wide application of 500 kV series reactors,es-pecially in regional grids with intensive short circuit current.
