The invention provides an intelligent power supply system for auxiliary power source of power grid-connection equipment, comprising: power grid-connection equipment and a power supply choosing circuit. The power supply choosing circuit is arranged between the power grid-connection equipment and the power grid. The power grid-connection equipment comprises the auxiliary power source which provides power to the blower fan inside the power grid-connection equipment. A breaker is arranged between the power grid-connection equipment and the power grid. When the breaker is off, the power grid-connection equipment is cut off from the power grid. When the breaker is closed, the power grid-connection equipment is incorporated into the power grid. According to the invention, the power supply choosing circuit is used to make the auxiliary power supply provide power from the grid output or from the prior inverted output and enables the power supply part to be connected with the output power supply point after the turn-of
