Group gradually develops to high parameter, large capacity, and the following steam-electric generating set shafting constantly extends, cause shafting stability and
Shafting vibration problem becomes especially prominent, and wherein frictional vibration problem proportion is increasing.Part of generating units is because vibration is asked
Topic causes unit to can not be successfully starting, and for thermal power plant, unit can not start on time not only causes power supply task
It is unable to complete, while to carry the consumption of unit cost during Unit Commitment, according to incompletely statistics, 300MW unit starting
Primary expense up to arrives hundreds of thousands, and in face of such huge expense, how to solve vibration problem makes unit safety stable operation
The problem of just become especially prominent.
In face of the competitive pressure of each electricity power enterprise, how to reach energy-saving, how to ensure unit safety trouble-free operation change
The problem that must be faced at each generation technology personnel.
Utility model content
The purpose of this utility model is to provide a kind of self contained magnetic suspension Turbo-generator Sets, it is intended to solve the prior art
Middle generator set vibration is larger, the higher problem of frictional dissipation.
The utility model is realized in this way a kind of self contained magnetic suspension generation unit, comprising:
Magnetic levitation system；The end of the shaft of the rotor of the generating set is set, pushes the rotor after energization
Float in the air,
Power equipment；It is electrically connected with the magnetic levitation system, provides power supply to the magnetic levitation system.
Further, the power equipment includes the alternating current driven to magnetic levitation system supply alternating current
Source, to the magnetic levitation system DC power supply that is driven of supply direct current and to the supply power supply of the magnetic levitation system
The conversion equipment that type is converted, the DC power supply include electrical storage device, the electrical storage device by the generating set into
Row charging；Before magnetic levitation system starting, the conversion equipment conversion alternating current is powered the magnetic levitation system,
After magnetic levitation system starting, the conversion equipment is converted the direct current and is powered to the magnetic levitation system.
Further, the generating set is Turbo-generator Set.
Compared with prior art, a kind of self contained magnetic suspension generation unit provided by the utility model not only eliminates tradition
The relevant device of the lubricating oil and grease pump of generating set, pipeline, reduces unit capital construction and operation expense, while by
In not needing traditional mechanical bearing, reduce the energy loss of generating set, and since rotor is contacted with air, also just keeps away
Exempt from rotor and generated frictional vibration, is greatly reduced unit vibration probability.The skill not only improves the operational efficiency of unit, simultaneously
Also electricity power enterprise's plant maintenance amount of reduction, the occurrence of more having reached reduction unit vibration.
Detailed description of the invention
Fig. 1 is a kind of principle framework figure of self contained magnetic suspension generation unit provided by the embodiment of the utility model.
Specific embodiment
