The invention provides a distributed SVC control protection system. The system comprises a coordination control platform and at least two SVC control platforms, wherein the coordination control platform is in communicating connection with an AVC control system and is connected with the SVC control platforms through fibers; the coordination control platform is used for formulating a control strategy for reactive adjustment of a transformer station; and the SVC control platforms, according to control instructions, adjust the trigger angles of thyristor valve sets and switching of reactors and capacitors. Compared to the prior art, the distributed SVC control protection system takes overall system voltages of the transformer station as a control target, can simultaneously coordinately control multiple SVCs in the station, realizes a balance of outputs of the multiple SVCs, can coordinately control all reactive output in a scope allowed by an operation mode in a unified manner, and when any SVCs or capacitor groups or reactor groups fail or are repaired, the control scope can be automatically re-adjusted.
