WIPO Patent Application WO/2016/034086

Kind Code:

A1

Abstract:

A power supply system and method. The power supply system comprises: a power grid input unit (101) and a diesel generator input unit (102), separately used for supplying an alternating current to a power supply unit (104); an automatic transfer switch unit (103), connected to the power grid input unit and the power supply unit or connected to the diesel generator input unit and the power supply unit; the power supply unit, used for converting the received alternating current into a direct current; and a control unit (105), used for monitoring a current load current and current diesel generator power, and determining to turn off a preset number of power supply loads according to a magnitude relationship between the current diesel generator power and the current load power and according to priority levels of current loads. By means of the power supply system and method, the power supply time is prolonged and the power supply reliability is improved.
