Abstract
An integrated gasification combined cycle that can adjust the balance of pressure/temperature in an overall plant and can stabilize the output of a gas turbine at an early stage during load variation, and an operation control method of the integrated gasification combined cycle are provided. When a calorific abnormality of fuel gas is detected during load variation of a gas turbine (5b), a load change command value of the gas turbine (5b) is set to zero or is decreased, and based on this load change command value, a power generation output command of the gas turbine (5b) is generated.
Claims9
An operation control method of an integrated gasification combined cycle, wherein when a calorific abnormality of fuel gas is detected during load variation of a gas turbine, a load change command value of the gas turbine is set to zero or is decreased, and based on this load change command value, a power generation output command of the gas turbine is generated.
An operation control method of an integrated gasification combined cycle, comprising:
- a first step of generating a power generation output command of a gas turbine using a value obtained by subtracting a power generation output of a steam turbine from a power generator output command,
- wherein a gasification furnace is controlled using the power generation output command of the gas turbine obtained in the first step.
