The invention discloses a power plant coal conveying section line switching method. The power plant coal conveying section line switching method comprises a spare power automatic switching method and a voltage loss automatic switching method. The spare power automatic switching method comprises the following steps that A1, charging conditions are as follows: the first inlet wire and the second inlet wire have three-phase voltage, the 1DL and the 2DL are closed, and the 3DL skips, and if the conditions are met, charging is started, and the charging time is 15 seconds; a2, the discharge conditions are as follows: 1, the section switch is on; according to the power plant coal conveying section line switching method provided by the invention, under the condition that the loop, hard wiring and device functions are not changed, whether the first incoming line and the second incoming line are closed or not is identified, logic optimization is carried out after the closed-loop condition is met, and the power plant co
