Abstract

The invention discloses a gas turbine starting control method and system which can solve the problems of starting process curing, long starting time and low starting success rate in a conventional gas turbine starting process. The system includes a self-adaptive correction unit, a starting control unit, a first maximum value selection gate, a first minimum value selection gate, a fuel control valve control unit, a gas turbine monitoring system and a fuel control valve.

Description

technical field [0001] The invention relates to the field of gas turbine control, in particular to a gas turbine startup control method and system. Background technique [0002] Usually, during the start-up process of the gas turbine, the starter drives the gas turbine to start. At the same time, the gas turbine start-up control system controls the fuel regulating valve (control valve) to provide the gas turbine with suitable fuel for combustion to generate power. As the speed of the gas turbine continues to rise, when After reaching a certain speed, the starter quits work, and the gas turbine is completely driven by the power generated by burning fuel to run to the rated speed (working speed). So far, the start-up of the gas turbine is completed. During the start-up process of the gas turbine, providing suitable fuel is the key to ensure normal start-up. At the same time, it is also necessary to ensure that the speed of the gas turbine does not exceed the speed, the exhaust...
