The invention provides a device for suppressing low-frequency oscillation of an electrified railway. The device is an electrified railway low-frequency oscillation suppression device based on TCSC (controllable series compensation) additional damping control, mainly utilizes traction network signals, does not depend on detailed control strategies and control parameters of locomotives, is high in adaptability, and can realize optimization of a rectifier control structure. Compared with other FACTS devices such as an MMC-STACOM, the device of the invention has the advantages that the voltage stability is maintained without depending on the angle of reactive power compensation, the additional damping of a vehicle network system is controlled and adjusted through the additional damping of TCSC, the effect of restraining the low-frequency oscillation of a traction network is achieved, and the effect of safe and stable operation of an electrified railway is guaranteed. The device also has the advantages of relatively simple control structure, easiness in realization, capability of realizing suppression of low-frequency oscillation of the traction network, high system stability and good suppression effect.
