In the conventional gas turbine device 1, when the gas generator rotation speed is in a high rotation range, the efficiency of each element constituting the gas turbine device 1 is high, but in the low rotation speed range, the efficiency is low, so the same variable vane There is little change in the amount of work of the gas turbine device 1 with respect to changes in the opening degree. That is, as shown in FIG. 5d, in the low rotation range, the gain of the gas turbine device 1 as the controlled object is lower than in the high rotation range. Therefore, the transient characteristics were worse in the low rotation range than in the high rotation range. In other words, the settling time for the gas general inlet temperature T7 to the target value is τ H in the high rotation range, as shown in Figure 4c, but in the low rotation range, it is τ H as shown in Figure 5c.
As shown in Figure 2, there was a drawback that τ LL > τ H ) was longer.

0) are given the same reference numerals and their explanations will be omitted. 5
Reference numeral 1 denotes a correction signal generator, and this generator 51 receives the above-mentioned gas generator rotational speed measurement value signal N G as an input, and sends out a correction signal ΔV GO to a code converter 52 . The correction signal ΔV GO is appropriately determined so that the correction amount is large when the measured gas generator rotational speed value N G is in the low rotation range, and decreases as N G becomes in the high rotation range. shall be. The code converter 52 gives the polarity of the temperature deviation (T 7 * −T 7C ) output from the comparator 23 to the correction signal ΔV GO output from the correction signal generator 51, and generates the variable vane opening adjustment signal. V GT correction signal ΔV GC

In other words, this control device adjusts the opening degree of the variable vane during steady operation.
Conventionally, variable vane opening adjustment signal V GT consisting of the deviation (T 7 * - T 7C ) between the set value and measured value of the gas general inlet temperature was used . This is done using a signal V GTC added with a correction signal ΔV GC depending on the height of the rotation speed. As a result, the gain of the regulator 24 is apparently higher in the low rotation range than in the high rotation range, as shown by d in FIG. 5, and the range of change in the work distribution ratio between the gas generation turbine and the power turbine is Expanded. Therefore, even in the low rotation range,
As shown in FIG. 5c, the settling time τ L ' is approximately equal to the settling time τ H in the high rotation range, so that transient characteristics equivalent to those in the high rotation range can be obtained.
