<p>PURPOSE:To improve following-up property for the AFC signal of the whole plant by setting a circuit means for applying lead signal according to the AFC signal, to input signal to a steam turbine controller. CONSTITUTION:A circuit means for applying lead signal according to frequency controlling signal(AFC signal) 3, to input signal to a steam turbine controller, is set. On the circuit means, when a plant load controller having composition so that objective load command 1 and the AFC signal 3 may be added to each other to be turned into power generation quantity command 5 is used, then the AFC signal 3 is directly used, and when the power generation quantity command 5 is directly transmitted from a central feed current command station, then by performing arithmetic on the power generation quantity command 5 with a differentiator 33, equivalent AFC signal is computed.</p> |
