A satellite bias momentum flywheel hot standby method comprises the following steps that two of three flywheels of a satellite are installed in a V shape around a pitch axis and are marked as an N1 flywheel and an N2 flywheel respectively, and the other flywheel is installed along a yaw axis and is marked as an Nr flywheel; the three flywheels are powered up for a long time, the power state of each flywheel is monitored, and if the power state of a certain flywheel is not powered up, it is judged that the corresponding flywheel has a power failure fault; if the Nr flywheel has the power-down fault, performing power-down fault processing on the Nr flywheel from the ground; if the power failure of the N1 flywheel or the N2 flywheel occurs, the attitude of a pitch axis is controlled by a flywheel without power failure, the attitude of a rolling axis is controlled by air injection of a thruster, and the rotation speed of an Nr flywheel is controlled; and finally, the power failure fault of the N1 flywheel or the
