Abstract

Control method and device for controlling a gas turbine plant (1) provided with at least a gas turbine (5), a combustion chamber (4) and a compressor (3); the method comprising the steps of: setting a plurality of reference values for respective operative parameters of the plant (1); detecting an activation condition; activating the correction of one or more reference values if the activation condition is detected; wherein the step of detecting the activation condition comprises: detecting a first value (IGVPOS(t1)) of a parameter indicative of the electrical power greater than a first threshold value in a first instant (t1); detecting a second value (IGVPOS(t2)) of the parameter indicative of the electrical power lower than a second threshold value in a second instant (t2) comprised in a time window which precedes the first instant (t1).

Description

technical field [0001] The present invention relates to a control method and a device for controlling a gas turbine plant for power generation. Background technique [0002] In recent years, the changing demands of the energy market have affected the operators of power generating facilities to always ensure peak power delivery. [0003] Known control devices are thus configured to guarantee maximum power delivery at all times, while ensuring reliability of the device during maximum energy delivery. [0004] However, known solutions lead to degradation of equipment performance during stationary operation periods during which power peaks are unnecessary. [0005] In fact, the reference values ​​of the controlled variables are strongly limited in order to guarantee the reliability of the plant even during transients during which a significant increase in the electrical energy output is required. Such a limitation is necessary during transients, where the delivered energy need...
