The present disclosure discloses a method and apparatus for controlling redundancy of a valve control system of a converter valve. The method includes: for each FPGA: in a case that the FPGA receives the on-duty state representing the active state: outputting a high-level control signal to a data selector through the FPGA; in a case that the FPGA receives the on-duty state representing the standby state: outputting a low-level control signal to the data selector through the FPGA, and maintaining a control signal output state of the FPGA and the other FPGA; and in a case that running state information of the other FPGA received by the FPGA through a monitoring output channel is a crash state: outputting a low-level signal to a control port of the other FPGA through the monitoring output channel by the FPGA.
