The application relates to an abnormal function module cutting method, system, device and controller. The method comprises the following steps: acquiring the operation parameters of each function module in a converter valve; the operation parameters are used for representing the operation state of the function module; judging whether the function module is normally operated according to the operation parameters of the function module; in the case that the function module is abnormally operated, controlling a trigger switch to be turned on, and in the case that the trigger switch is turned on, controlling a bypass switch to be turned on; wherein the first end of the bypass switch is used for connecting the first end of the function module, the second end of the bypass switch is used for connecting the second end of the function module; the first end of the trigger switch is used for connecting the first end of the function module, and the second end of the trigger switch is used for connecting the second end of the function module. By adopting the method, the main circuit in the function module can be quickly and accurately cut off in the case that the function module in the converter valve is abnormal, so that the normal operation of other function modules in the converter valve is ensured.
