In the utility model embodiment, important composition portion of the filter unit as starter-generator simulator is adjusted
Point, be the key that starter-generator simulator can accurately simulate different model, different parameters true motor, and be different from
The key of technical grade motor simulation device at present is mainly used for the stator inductance of simulated firing generator.Starter-generator simulator
Main task be to simulate the port reference current characteristics of true motor, and the port reference electric current of true motor levels off to sine
Wave.In order to enable the current waveform of the starter-generator simulator preferably true motor of simulation, it is necessary to the properly adjustable filter of design
Wave unit, to be filtered to port current.The inductance of adjustable filter unit is bigger, is got over to the filter effect of port current
It is good.But the value of filter inductance cannot unlimitedly increase, and be limited by starter-generator simulator DC bus-bar voltage.
In order to facilitate understanding, the utility model embodiment is illustrated by taking non-salient pole permanent magnet synchronous motor as an example.Fig. 2 f are these
A kind of schematic diagram of the equivalent circuit for non-salient pole permanent magnet synchronous motor that utility model embodiment two provides.As shown in figure 2f, whereinFor counter electromotive force of motor,For motor port voltage, XsSynchronous reactance for motor per phase winding, RaFor the electricity of every phase winding
Resistance.For a designed motor, under certain rotating speed,XsWith RaIt is constant.And in different control
Under method and load, amplitude and the phase of armature supply have very big difference so that its armature reaction electric potentialAlso have very
Big difference.But no matter under which kind of operating mode, each electricity in equivalent circuit diagram Fig. 2 f is both needed to meet basic circuital law,
Otherwise this operating mode can not possibly then exist.If to simulate a motor completely, need to only provide identical with true motor
'sXsWith Ra, can determine that starter-generator simulator can run all operating modes of true motor at this time.
But due to true motorApproximate sine wave, depending on sub- simulator outputContain a large amount of switch
The harmonic wave of frequency and its integral multiple.To make the electric current that stator simulator exports in THD (Total Harmonic
Distortion, total harmonic distortion) on can be drawn close to the port reference electric current of true motor, the filter reactance of stator simulator is answered
It is more true X than motorsLarger.The filter reactance of bigger makes the pressure drop in filter reactance increase, therefore in identical port voltage
In the case of,Value also accordingly to increase.It can be provided due to stator simulatorBy straight in starter-generator simulator
The limitation of busbar voltage is flowed, therefore the value of filter inductance can not be increased unlimitedly, according to the difference of motor operating mode, there are one
Enable the upper limit value of circuit steady-state operation.Frequency under a certain operating mode is bigger or port current is bigger, then in filter reactance
Pressure drop it is also bigger, the upper limit value of filter inductance is also just smaller.
Fig. 2 g are a kind of stator simulator exchange side stable state vector correlation figures that the utility model embodiment two provides, specifically
, under stator simulator limit, the vector correlation of pressure drop on the voltage and inductance of stator simulator filter inductance both sides
As shown in Figure 2 g.Stator simulator exchange side resistance is had ignored in Fig. 2 g, and fundamental wave sinusoidal electric quantity is only discussed.In figure 2g, V is
Stator simulator exchange side phase voltage phasor, the phase voltage fundamental phasors that U is starting-generating machine controller exchange side, I are to start
Engine controller exchange side phase current phasor, VLIt is the pressure drop on adjustable filter unit.When | U | it is constant, and | I | it is certain
When, as the variation phasor V endpoint traces of power-factor angle ψ are with | VL| it is the circle of radius.A, C is stator simulator work(respectively
The state point for the pure reactive power that rate factor is 0, B, D are stator simulator unit power factor rectifier, inverter mode respectively
Operating point (stator simulator exchange side reference direction Motor convention).As stator simulator DC voltage VpnIt is fixed after determination
Sub- simulator exchange side peak-peak also just determines therewith, i.e., | V |max=MVpn.Wherein, M is PWM (Pulse Width
Modulation, pulse width modulation) phase voltage peak use rate, according to SVPWM (Space Vector Pulse
Width Modulation, space vector pulse width modulation) modulation, then
With the variation of power factor and I, the size and Orientation of V can change in Fig. 2 g, U, V, VLConstitute one
A phasor triangle.But by | V |max=MVpnIt is found that the maximum value of V is by VpnLimitation, therefore the adjustable maximum magnitude of V is
With O1For the center of circle, | V |maxFor the circle of radius.And U, V, VLTwo vertex of phasor triangle are fixed, and third vertex is located at O
For the center of circle, | VL| on the circle of radius, wherein E, F are the limit point intersected with circle O that voltage V can reach respectively.Fig. 2 h are
A kind of stator simulator exchange side stable state vector correlation figure that the utility model embodiment two provides.As shown in fig. 2h, if | VL
| too big and system is generated electricity with non-unity power factor, then is likely to occur phasor triangle third vertex and is located at circle O1Except
Situation.Since V can not reach this vertex at this time, system can not be run under this operating mode.
From the foregoing discussion, it should be apparent that under a certain port voltage electric current | VL| size determine that can system simulate this operating mode.It is holding
In the case of known to mouth voltage, port current, need to make limitation to the inductance value that filter unit is adjusted to limit | VL| size.It can
Adjust the maximum value inductance value L of filter unitmaxIt can be given by：
Wherein, f is current first harmonics frequency.
Judge that can starter-generator simulation system simulate the parameter of certain a set of true motor, a certain motor control is calculated
Method or some motor operation operating mode are inherently to judge that can the system simulate all motors corresponding to the above situation
Port voltage, port current situation.Therefore, it needs to find out first when judging to be simulated closest to starter-generator simulation system
The port voltage for the potential limit of uniting, the port current situation (feelings that port voltage is high, port current is big, power factor is small, frequency is high
Condition), then consider whether voltage and current amplitude has exceeded the limitation of switching device (transistor) and over-voltage over-current protection circuit.
If not provided, further according to formulaCalculate a certain port voltage, end
L under mouth electric currentmaxValue.If what adjustable filter unit was selected is the inductor with tap, and LmaxLess than any one
Tap inductor value, then this port voltage electric current cannot be simulated by showing starter-generator simulation system centainly.Conversely, selection ratio
LmaxThe tapped inductor small, inductance value is larger as possible is simulated.Therefore for the design of adjustable filter unit
In selection, the inductor with tap for selecting a larger inductance value range is needed, a tap is pulled out every certain inductance value,
It is customized according to actual demand.In addition, since adjustable filter unit is extremely important during hardware is debugged, so
If it is required that the motor characteristic simulation precision of setting model aircraft is more demanding, being adapted to property design setting inductance value is replaced
Inductor is changed, and the replaceable inductor of inductance value will be set as adjustable filter unit.It is single by adjustable filtering
The design or replacement of member can make starter-generator simulator (starter-generator simulation system) can be compared in the angle of hardware
