The invention relates to the technical field of industrial system control and provides an automatic intelligent cooling system and method of a gas turbine. According to the automatic intelligent cooling system of the gas turbine, the working states of the gas turbine and the cooling system can be detected through a data collector, a controller analyzes the data obtained by the data collector, and by controlling a control system of an executing device and the gas turbine, automatic control over the gas turbine and the cooling system is achieved. The system can be used as an independent control system, under the situation that turbine rotor temperature is not high, starting is of no need, the resources of a gas turbine main control system are saved, and maintaining is convenient. In addition, the system achieves a pre-diagnosing function and has the advantages of being good in economy, easy to operate and convenient to operate.
Description
technical field [0001] The invention relates to the technical field of industrial system control, in particular to an automatic intelligent cooling system and method for a gas turbine turbine. Background technique [0002] The air extracted from the outlet of the compressor by a certain type of gas turbine is cooled by cooling water, and then this part of the cooled air is used to cool the internal components of the gas turbine (rotors and blades, etc.). The air cooled by the gas turbine air cooler is reinjected to cool the turbine blades at all stages. Among them, the cooling method of the gas turbine air cooler is water cooling, the cooling water is taken from the high-pressure feed water of the combined cycle power station, and the heated cooling water flows to the condenser (route 1) and high-pressure steam drum (route 2). Route 1 is used for the start-up process of the unit, low-load operation of the gas turbine and emergency situations. [0003] The outlet air temper...
