The invention provides a solid-state fault current limiter, including a current-limiting reactor L1, a current-limiting reactor L2, a current-limiting reactor L3, a thyristor valve T1, a thyristor valve T2 and a bypass breaker K. The current-limiting reactor L1 and the current-limiting reactor L2 are connected in series to form a current-limiting reactor branch, the thyristor valve T1 and the thyristor valve T2 are connected in series to form a thyristor valve branch, the bypass breaker K and the thyristor valve branch are connected with the current-limiting reactor branch in parallel, one end of the current-limiting reactor L3 is connected with the midpoint of the current-limiting reactor L1 the current-limiting reactor L2, and the other end is connected with the midpoint of the thyristor valve T1 and the thyristor valve T2. The technical scheme provided by the invention can realize nearly no influence on an electric power system during normal operation, and after a fault occurs, short circuit currents are automatically limited. The solid-state fault current limiter provide by the invention has a low requirement for fault identification speed, is simple in structure, has no full-control type power electronic device, can adjust current-limiting effects on a short circuit current peak value and steady-state value by changing the current-limiting reactance, and is convenient for engineering application.
