Description
Technical field
The present invention relates to switched reluctance machines fields, and in particular to a kind of low power intelligent multi-function switching magnetic-resistance electricity
Machine converter structure and its control method.
Background technique
Switched reluctance machines structure simple rigid, without winding, without permanent magnet on rotor, the pressure that radiates is small, high reliablity, system
Make low in cost, a phase winding, which does not work not, in the middle influences the normal work of other phase windings, and fault-tolerance is strong, has wide answer
Use prospect.
Switched reluctance machines are generally symmetrically distributed in stator salient poles by multiple phase windings, according to salient pole between rotor and
The relative position of groove determines that the phase winding being specifically powered, each phase winding distinguish work according to opposite rotor position information timesharing
Make；When as generator work, every phase winding is generally divided into excitation and two big stages of power generation when working, in winding inductance maximum area
Be powered excitation first before and after domain, and excitation stage motor phase windings absorb the electric energy storage magnetic energy of external field power supply, subsequent basis
Real-time rotor position information terminates the excitation stage and the change of current enters power generating stage, and it is defeated that the magnetic energy stored in phase winding is converted into electric energy
Out, electric current is down to zero completion work when entering winding inductance Minimum Area；When as electric motor operation, every phase winding work
Main body is the excitation stage, and be powered excitation when winding inductance Minimum Area or inductance rise and start, maximum wait enter winding inductance
Shutdown excitation completes work before and after region, provides continuous current circuit after excitation when necessary and releases the remaining magnetic energy in winding
It puts.
The excitation of switched reluctance machines, power generation will be controlled around the operation for the convertor circuit for connecting its winding realizes do not have
There is winding convertor circuit, the operation of switched reluctance machines is not just known where to begin, so current transformer is significant.
When switch reluctance generator is run, existing converter system, in the excitation stage, field power supply is much all realized certainly
Mode is encouraged, is not necessarily to frequently replace the manual working of battery or charging under separate excitation mode in this way, but existing many self-excitation modes
It selects increase excitation circuit directly to provide field power supply, but needs individual battery branch to provide starting when generator starting and encourage
Magnetoelectricity source, increases structure complexity.
As wind-powered electricity generation operating condition application field, switch reluctance generator generally requires one after current transformer issues direct current energy
The boosting inverter of grade or multistage can just be supplied to load or power grid, if so current transformer itself has certain boost capability,
Subsequent burden and structure certainly will then be reduced；And presently, there are in more converter structure, it is defeated to generally require its direct current
First inversion, then rectifies after transformer isolation and boosting again after out, if realizing alternating current simultaneously by current transformer itself
Output, then can save inversion link.
Wind-powered electricity generation field more particularly to it is grid-connected when, generator system must have low voltage ride-through capability, double-fed asynchronous wind
Hardware system and complicated control method needed for force generating system there is complicated low voltage crossing generate electricity as switching magnetic-resistance
Machine certainly will play grid-connected for low-voltage crossing etc. or load end if excitation circuit has the link of feedback energy regenerative
Alleviation is played the role of in strong variation, provides flexible selection；Simultaneously, it is contemplated that when power generation enhanced excitation and maximum power point with
There is wider output to encourage for the needs of raising speed adjusting performance when track, maximum power generation efficiency needs or electric operation, excitation circuit
Magnetic voltage regulation limits are also necessary.
Currently, no matter the converter structure of switch reluctance generator is equipped in view of self-excitation starting or separate excitation operation
Have battery, then replaced from time to time according to accumulator electric-quantity battery or it is artificial participate in charging operation be it is essential,
If being able to achieve automatic intelligentized charging operation, the reliability and intelligent level of converter system certainly will be improved.
Intelligent micro-grid and hydroenergy storage station are two fields that China greatly develops in recent years, the two are combined, i.e.,
The middle-size and small-size hydroenergy storage station of local micro-capacitance sensor is not taken seriously then, as power station when this field needs short of electricity in power grid
Power generation, is pumped up water using water pump when power grid electric is more and consumes electric energy, it is often necessary to be completed using different electric systems.
