The invention provides a general fixed series capacitor compensation device, which comprises a series capacitor bank C, an over-voltage protection device and a damping device D, wherein the over-voltage protection device is connected with the series capacitor bank C in parallel; the damping device D is connected with a spark gap G and a by-pass switch S1 in series separately and then connected with the series capacitor bank C in parallel; and the damping device D is connected with a by-pass switch S2 in parallel. The general fixed series capacitor compensation device can be used for conventional fixed series compensation, can also be used for submerged fixed series compensation, and adapts to multiple system working conditions and operation modes; and the flexibility and the reliability are relatively.
