| Abstract |
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. |
