Sažetak
A synchronous generator connected to an AC system in capacitive operating mode is near its stability limit. In such conditions, if some disturbances in the system appear, a synchronous generator could lose the synchronism. The classical solution of this problem is to keep a generator in stabile operating range of P-Q diagram by limiting the minimal excitation current. This article analysis impact of additional control algorithms which are included in classical excitation regulation system with the purposes of keeping a generator in synchronism when some disturbances appear and generator is near its stability limit. These control algorithms include load angle estimation by corresponding P-Q diagram and load angle regulator which task is to keep the load angle of a synchronous generator operating in capacitive mode on the reference value so that generator remains in synchronism.
