| Abstract: | The short-circuit current problem is serious in East Chin Power Grid.As a solution,the short-circuit current limiter can quickly bypass its capacitor with the help of the thyristor and display inductive impedance during short-circuit faults,which can limit the short-circuit current.Since the short-circuit current limiter for EHV grids is expected to put into operation in 2010,the siting scheme for its demonstration project is studied from the point of view of its control effectiveness. |
