The present invention relates to a system for detecting an abnormality of a carbon dioxide separation membrane plant, comprising: an inlet part for introducing, into the plant comprising carbon dioxide separation membrane modules, gas containing carbon dioxide; an injection hole for supplying, to each carbon dioxide separation membrane module, the gas containing carbon dioxide; the separation membrane module for making the supplied gas permeate a carbon dioxide separation membrane, and separately discharging the supplied gas such that gas having a relatively high carbon dioxide concentration, having permeated the separation membrane, is discharged through a first discharge port, and gas having a relatively low carbon dioxide concentration, not having permeated the separation membrane, is discharged through a second discharge port; a permeation part for discharging, to the outside of the plant, the gas having a relatively high carbon dioxide concentration and discharged from the separation membrane module; a retention part for discharging, to the outside of the plant, the gas having a relatively low carbon dioxide concentration and discharged from the separation membrane module; a measurement unit for measuring information including flow rate, carbon dioxide concentration and pressure in the inlet part, the permeation part and the retention part; and a control unit for determining whether the information collected from the measurement unit is abnormal, wherein the control unit determines whether the plant is in an abnormal state.
