<p>PURPOSE:To safely and securely perform serial load control as to respective shafts. CONSTITUTION:The serial load controller having a control system which equalizes the power generation output of the whole series in the operation of the single shaft type or multishaft type complex power plant, which generates steam with an exhaust heat recovery boiler by using the exhaust gas of plural gas turbines and drives steam turbines by using the steam generated by the boiler to a serial load command is equipped with a feedforward calculation part 30 which calculates a feedforward signal from the serial load command and respective shaft load command predicted values. Then, the controller is equipped with a respective-shaft model part 31 which can calculates respective shaft power generation output predicted values from the feedforward signal calculated by the feedforward calculation part 30 and when there is deviation between the serial load command and the respective shaft power generation output predicted values calculated by the respective-shaft model part 31, the feedforward calculation part 30 calculates the feedforward signal matched with the shaft which can vary in load fastest and supplies it to the control system.</p> |
