The invention discloses a power transmission line UAV (unmanned aerial vehicle) inspection simulation training method. The simulation training method comprises the following steps: 1) data acquisition; 2) 3D model building; 3) barrier setting; 4) typical fault setting; and 5) wind and rain resistant flight setting. Compared with the prior art, the method has the advantages that by combining virtuality with reality, a 3D model is built in the simulation training process, thus maximally restoring the reality; and the control capacities of drivers can be trained in an omnibearing and multi-angle manner by setting typical faults, barriers and wind and rain resistant flights in the simulation training process.
