摘要： An integrated excitation and turbine controller (23) for a synchronous generator (20) and a control method thereof are provided. The method comprises following steps: categorizing the fault severity according to the accelerating energy caused by the power mismatch; detecting the generator operation mode according to the signs of power angle derivation and the directions of electromagnetic power; calculating the auxiliary excitation voltage according to the fault severity and the generator operation mode; calculating the auxiliary governor valve opening according to the fault severity and the generator operation mode; and calculating the intercept valve opening according to the fault severity and the generator operation mode. The disturbance severity categorization and the generator operation mode are both considered in the method based on the local measurements (29) so as to determine the best combination of the auxiliary excitation and the turbine control under various system disturbances and operation conditions. The outputs of the integrated excitation and turbine controller (23) will be added into the existing generator controllers for generator transient stability enhancement and dynamic performance improvement. When the disturbances disappear, the outputs of the integrated excitation and turbine controller (23) will be phased out automatically so as to minimize the impacts on the generator steady-state voltage and the frequency regulations.

摘要： An electrical machine with a rotor 112 or the stator 104 comprising a plurality of discrete field modules 102, and the other one of the rotor 112 and the stator 104 comprising a plurality of armature coils 114 connected to different power converters. Each field module 102 comprises one or more field coils 106 which can be activated independent of the field coils 106 of the neighbouring field modules 102. When at least one of the field coils 106 is inactivated, e.g. because of a defect, each of the power converters is allowing less power to pass through when an armature coil 114 connected to it is moving over an inactivated field coil 106, and more power to pass through when the armature coil 114 connected to it is moving over an activated field coil 106.
