Title:
燃料ガス加熱制御装置及びこの燃料ガス加熱制御装置を備えるガスタービン発電施設
Document Type and Number:
Japanese Patent JP4568592
Kind Code:
B2
Abstract:
A fuel gas heating control equipment in accordance with the present invention is provided with a gain-determining portion 21 and a time-constant-determining portion 22 which determine values of a gain and a time constant to be used for PI calculations being performed by a PI calculation portion 14. The gain-determining portion 21 specifies a small time constant for the PI calculation portion 14 during load fluctuations when the generator output increases, and specifies a large time constant for the PI calculation portion 14 when the generator output reaches the maximum output. In consequence, during load fluctuations, responsiveness is good and a rapid change in temperature can be followed, so that a fuel gas temperature will not fluctuate in response to a slight change in temperature at the maximum output, thereby achieving a stable fuel gas temperature.
