Abstract

The invention provides a rotor system and a control method of the rotor system as well as a gas turbine generator set and a control method of the gas turbine generator set. The rotor system comprisesa rotating shaft, a generator, a gas compressor and a turbine as well as a thrust bearing and at least two radical bearings, wherein a shaft body of the rotating shaft is of an integrated structure and is horizontally arranged, the generator, the gas compressor and the turbine are sequentially arranged on the rotating shaft, the thrust bearing and the radial bearings are arranged on the rotating shaft, the thrust bearing and the radial bearings are non-contact bearings, and the thrust bearing is arranged at the position where the gravity center of the rotor system can be located between two radial bearings which are spaced by the largest distance. According to the rotator system, the shaft body of the rotating shaft in the rotor system is arranged into the integrated structure, so that theproblem that the installation position of a gas-magnetic hybrid thrust bearing is limited due to the fact that a coupling is used for connection in an existing gas turbine generator set is solved; and the arrangement position of the thrust bearing is adjusted, so that the gravity center of the whole rotator system is located between the two radial bearings which are arranged at the farthest distance, and the structure can be kept stable when the whole rotor system rotates at a high speed.

Description

technical field [0001] The invention relates to the technical field of rotors, in particular to a rotor system and a control method thereof, a gas turbine generator set and a control method thereof. Background technique [0002] A gas turbine mainly includes three major components: a compressor, a combustor, and a turbine. After the air enters the compressor, it is compressed into high-temperature and high-pressure air, and then supplied to the combustion chamber for mixed combustion with fuel, and the high-temperature and high-pressure gas generated expands in the turbine to perform work. When the rotor rotates at high speed, the rotor will be subjected to radial force and axial force. In order to limit the radial and axial movement of the rotating shaft, radial bearings and thrust bearings need to be installed in the rotor system. Traditional radial bearings and thrust bearings are common contact bearings. As the rotor speed increases, especially when the rotor speed exc...
