<p>PURPOSE:To obtain an exciter for a synchronous machine which does not largely vary at the terminal voltage of the machine by a system stabilizer even when a stabilization signal signification varies slowly due to the fluctuation of the power. CONSTITUTION:A stabilization signal P is fed to a phase compensator 30 through a signal resetter 21 of a system stabilizer 20, a phase compensator 22 and a gain controller 23. The compensator 30 has a transfer function of both the gain controller 14 of an automatic voltage regulator 10 and a stepout preventing circuit 15. The output of the compensator 30 is applied to an adder 31 through a limiter 24. The adder 31 ads the output of the circuit 15 and the output of the stabilizer 20. In this manner, even when the stabilization signal significantly varies slowly due to the fluctuation of power, the terminal voltage of a synchronous machine is not largely varied.</p> |
