The loss of magnetism of large-capacity generators has a great impact on the system. Therefore, the generator is not allowed to operate without excitation before it is generally determined by experiments. When the generator loses its magnetic asynchronous operation, the general processing principles are as follows: 1. Generators that do not allow non-excitation operation should be immediately disengaged from the grid to avoid damage to equipment or system accidents. 2. For generators that allow non-excitation operation, the following operations shall be performed in accordance with the non-excitation operation regulations: 2.1 Rapidly reduce the active power to the allowable value (the power value specified by the factory for the loss of magnetism is consistent with the average value of the meter swing), at which time the stator current will swing around the rated current. 2.2 Manually disconnect the de-excitation switch and exit the automatic voltage regulator and the generator forcibly exciting the device. 2.3 Pay attention to whether the stator current and reactive power value of other normal running generators exceed the regulations, and if necessary, according to the allowable overload regulations of the generator. 2.4 Perform a quick and detailed inspection of the excitation system. If it is a problem with the working exciter, the standby excitation should be started quickly to restore the excitation. 2.5 Pay attention to the branch voltage level of the factory, and if necessary, pour it to the backup power supply. 2.6 In the time when the non-excitation operation is specified, the unit cannot be re-energized, and the generator should be disengaged from the system.
