A method for voltage dip compensation of inverter, the method characterized by: performing a momentary voltage dip test for grasping a load characteristic of a load installed at a field site with a basic set point to cope with a momentary voltage dip; determining whether a relevant load is a load that requires an additional current control in response to the grasped load characteristic; setting the relevant load as a current control subject when it is determined that the relevant load is the current control subject as a result of determination, and setting the relevant load as not a current control subject when it is determined that the relevant load is not the current control subject as a result of determination; setting to perform a momentary voltage dip compensation using voltage and current control on a relevant inverter when a momentary power failure occurs to a load which is set as the current control subject during inverter operation (S5, S6); reducing an output frequency of an inverter to obtain a regenerative energy when it is determined that power failure has occurred during the inverter operation (S11, S12); adjusting increase/decrease of inverter output frequency in response to size of exceeding current and voltage based on an output current and DC-link voltage of the inverter (S14, S15, S16, S17); increasing an inverter output voltage in order to prevent excessive current flow when power restoration occurs at a power failure state; and returning to a speed prior to the momentary voltage dip by gradually increasing the inverter output frequency in a state where an inverter output current does not exceed an over-current limit by monitoring the inverter output current (S24, S25, S26, S27). performing a momentary voltage dip test for grasping a load characteristic of a load installed at a field site with a basic set point to cope with a momentary voltage dip; determining whether a relevant load is a load that requires an additional current control in response to the grasped load characteristic; setting the relevant load as a current control subject when it is determined that the relevant load is the current control subject as a result of determination, and setting the relevant load as not a current control subject when it is determined that the relevant load is not the current control subject as a result of determination; setting to perform a momentary voltage dip compensation using voltage and current control on a relevant inverter when a momentary power failure occurs to a load which is set as the current control subject during inverter operation (S5, S6); reducing an output frequency of an inverter to obtain a regenerative energy when it is determined that power failure has occurred during the inverter operation (S11, S12); adjusting increase/decrease of inverter output frequency in response to size of exceeding current and voltage based on an output current and DC-link voltage of the inverter (S14, S15, S16, S17); increasing an inverter output voltage in order to prevent excessive current flow when power restoration occurs at a power failure state; and returning to a speed prior to the momentary voltage dip by gradually increasing the inverter output frequency in a state where an inverter output current does not exceed an over-current limit by monitoring the inverter output current (S24, S25, S26, S27).
