Problems solved by technology

The winding method, iron core and iron yoke structure of the magnetic control reactor are quite different from the conventional two-winding or three-winding transformer. Therefore, there is no magnetic control reactor model that can be directly used in the current electrical simulation software. Makes it impossible to perform electromagnetic or electromechanical transient simulations on power grids containing magnetically controlled reactors
