The invention provides a remote shutdown control system and control method of an uninterruptible power supply. By means of the circuit structure design of a power supply control branch, a remote shutdown enable branch and a shutdown trigger branch, the uninterruptible power supply can be effectively controlled to execute remote shutdown in the case that the power-off duration of a mains supply reaches a preset power-off time, or the electric quantity of the uninterruptible power supply is less than a preset electric quantity limiting value in a power-off state of the mains supply, therefore the damage risk of the uninterruptible power supply due to the deep discharge of a built-in battery is reduced, over discharge protection control of the operation of the uninterruptible power supply ina wind turbine generator is achieved, in the case that the uninterruptible power supply is working normally and the mains supply is not powered off, even if a remote shutdown enable signal output endof a main controller sends
