Abstract:
1. A gas turbine load control device comprising: load setting means which gradually increases a load set value at a predetermined pace of increase until the load set value reaches a requested load set value when the requested load set value is increased, and which gradually decreases the load set value at a predetermined pace of decrease until the load set value reaches the requested load set value when the requested load set value is decreased; first bias setting means which sets a positive side bias value as a bias value for the load set value; second bias setting means which sets a negative side bias value as the bias value for the load set value; target output setting means which sets a target output for a power generator by adding the positive side bias value to the load set value when the load setting means gradually increases the load set value in response to the increase in the requested load set value, and which sets the target output by subtracting the negative side bias value from the load set value when the load setting means gradually decreases the load set value in response to the decrease in the requested load set value; output deviation operating means which calculates output deviation between the target output and an output of a power generator to be measured by power generator output measuring means; and proportional-integral controlling means which controls flow rate controlling means for fuel of a gas turbine configured to rotate the power generator, by performing a proportional-integral operation based on the output deviation.
