Abstract
Provided are a bearing detection method, a bearing detection system, a method for starting a gas turbine and a system for starting a gas turbine. The bearing detection method includes: starting a rotor to enable the rotor to rotate at a first rotating speed along a first direction, wherein the first direction is a rotating direction when the rotor operates normally, and the first rotating speed is a calibration value; acquiring a first torque, wherein the first torque is an output torque when the rotor rotates at the first rotating speed along the first direction; and judging the first torque and a torque threshold value, wherein the torque threshold value is a calibration value, and if the first torque is smaller than the torque threshold value, it is judged that a bearing is fault-free.
