ABSTRACT:
A programmable autosynchronizer for use with a system having generator and bus voltages and having a breaker circuit for connecting the generator and bus voltages to each other. The autosynchronizer synchronizes the frequency and phase of the generator and bus AC voltages by controlling the generator voltage. A microprocessor compares the frequencies of generator and bus voltage signals, the microprocessor generating a proportional difference signal having a parameter representative of a proportional difference in frequency between the generator and bus voltage signals. The proportional correction range extends within the synchronization range. The microprocessor permits a sync signal when the frequency difference of the frequencies of the generator and bus voltage signals is within the synchronization frequency range. A first output circuit responsive to the proportional difference signal provides a correction signal to the generator for varying the frequency of the generator. A second output circuit responsive to the sync signal provides a breaker close signal to the breaker circuit for closing the breaker thereby enabling connection of the generator and bus voltages. A frequency correction dead band within the frequency range and a target slip band within the dead band define a zone of limited proportional correction to nudge the generator into synchronization and prevent a hung scope.
