摘要： Methods, systems, and computer readable media for adaptive out of step protection for power generators with load resynchronization capability are disclosed. According to one method, when a fault condition occurs in a load being supplied by a power generator, a number of pole slips expected to occur in the generator due to the fault before resynchronization is estimated. It is determined whether the estimated number of pole slips exceeds a threshold. An offline or online status of the generator is controlled based on the determination as to whether the estimated number of pole slips exceeds the threshold.

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.

The method comprises estimating an amplitude of fault-induced travelling waves at the fault location (1 07), and calculating a fault resistance (Rf) based on the estimated amplitude, an estimated pre-fault voltage at the fault location, and a surge impedance of the transmission line.
