Abstract

PURPOSE: To obtain a good control characteristic particularly in a speed control region with a inflow amount of steam through adjustment of the opening of the steam valve opening according to deviation between a target inflow amount of steam and the actual amount thereof.
CONSTITUTION: When a uncontinuous target speed NR is given a control apparatus, a change rate controller 41 calculates a continuous instantaneous target speed signal NR1. The change rate of the signal R1, namely, the target acceleration f'(NR1) is computed with a differentiator 14. In other words, a deviation calculated by a device which computes a deviation 13 for the item of non-load loss in the equation and a device which computes a deviation 20 for the item of acceleration energy in the equation is added with an adder 40. According to the total deviation, a proportional plus integral adjustor 26 calculates the required opening of the steam valve and provide an opening signal to an actuator 2 to yield a good speed following property.
