Combustion process control and optimization system for combustion gas turbine

Abstract

The invention discloses a combustion process control and optimization system for a combustion gas turbine, which can be used for solving the problem that an existing combustion process is difficult to control and optimize in real time. The system comprises an online monitoring unit, an analyzing and predicating unit and a strategy assessing unit, wherein the online monitoring unit is used for feeding back acquired data information of the combustion process in real time to the analyzing and predicating unit to perform data processing and analysis according to the combustion process data information acquired by monitoring equipment to emit warnings for problems in the combustion process, and performing online regulation according to the control strategy given by the strategy assessing unit to complete online control and optimization; the analyzing and predicating unit is used for analyzing the combustion process data information fed back by the online monitoring unit to predicate the combustion process; the strategy assessing unit is used for determining the control strategy corresponding to the predicated results according to the predicated results of the analyzing and predicating unit and the preset combustion performance judge criterions, and feeding back the control strategy to the online monitoring unit in real time.

Description

technical field [0001] The invention relates to the field of gas turbine control, in particular to a gas turbine combustion process control and optimization system. Background technique [0002] The combustion process is mainly carried out in the combustion chamber of the gas turbine, which is located between the compressor and the turbine and is one of the three major components of the gas turbine. The combustor of a gas turbine converts the chemical energy stored in the fuel into heat energy by mixing the compressed air from the compressor with the fuel injected by the fuel nozzle for effective combustion, and forms high-temperature gas that enters the turbine to expand and perform work. At the same time, the combustor is also the main adjustment component of the gas turbine (the most basic adjustment method of the gas turbine is to change the fuel supply into the combustion chamber). When the load of the unit changes, it is necessary to ensure not only its own operating e...
