Novel frequency converter hot redundancy system and method

The invention discloses a novel frequency converter hot redundancy system and method, and the system comprises the steps: a configuration module detects the working state parameters of a drive motor, and configures the initial operation parameters of two frequency converters connected with the drive motor according to the working state parameters; the adjusting module carries out troubleshooting on the two frequency converters, and when it is confirmed that the first slave frequency converter is in a fault shutdown state, the initial operation parameter of the second slave frequency converter is adjusted to be a target operation parameter; the access judgment module performs re-access judgment on the first slave frequency converter in the driving motor system after the maintenance of the first slave frequency converter is completed; and the synchronization module detects the voltage phase and amplitude of the driving motor stator, synchronizes the voltage phase and amplitude to the first slave frequency conve
