The invention relates to a method for commissioning a switching station without power outage, which comprises a first line, a second line, a first electric pole, a second electric pole, a section I bus, a section II bus, a power supply A, a power supply B, a power supply C and a power supply D. The method comprises the following steps: S1, checking electrical equipment of the switching station, and installing a 10kV cable; s3, a straight pole is changed to a terminal pole for operation; S4, dual-power-supply loop closing is performed; and S5, a dual-power-supply loop opening method is put into operation of a switching station. The method has the advantages that the first line is cut into the line 1 and the line 3 in the step S3, and the second line is cut into the line 2 and the line 4, so that the I-section bus and the II-section bus form a dual-power closed loop, a user does not need to be powered off in the switching station commissioning process, and non-perceptual power grid maintenance of the user is re
