Testing device and method for hierarchical controllable shunt reactor valve control system

The invention discloses a testing device for a hierarchical controllable shunt reactor valve control system. The testing device comprises a test power supply (Su), inductors (Xs), a three-phase switch (Ks) and a valve control system, wherein the test power supply (Su) is in series connection with the inductors (Xs) and is then connected with the input terminal of the three-phase switch (Ks), any two phases of the output terminal of the three-phase switch (Ks) are respectively in parallel connection with the valve control system and a lightning arrester (M1). Through adjusting the test power supply (Su) and the inductors (Xs) and controlling a thyristor valve (TK1), electrical conditions, before/after capacity adjustment switching and during the process of transient state switching, of various devices in the valve control system are equivalently provided, and the transfer of current between the valve and a circuit breaker in an adjustment process of the valve control system, and the electrical work intensity of the valve and the circuit breaker and the working condition of the valve at a switching stage are then verified.
