Disclosed herein are a multi-air conditioner central control system and a power control method thereof. The central control system comprises a plurality of watt-hour meters for measuring power consumption of a plurality of multi-air conditioners each having an outdoor unit and a plurality of indoor units, to compute power consumption of the respective indoor units, and a central control unit for dividing power consumption of the respective indoor units into operating power consumption and standby power consumption according to operation or non-operation of the respective indoor units and a particular one of the outdoor units connected with the indoor units, and accumulating integral power consumption of the respective indoor units by adding the operating power consumption and standby power consumption thereof. The power control method is adapted to determine whether the respective multi-air conditioners are in operation or not to allocate a larger portion of available power to multi-air conditioners in operation through power redistribution. Thus, power consumption states of the respective multi-air conditioners can be more accurately identified in real time, and power management of the multi-air conditioners can be efficiently performed.
