Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, the present invention will be further described.
The band subring energy-storage system of the present embodiment includes three H bridge modules, and tuning filtering device includes inductance Lr, electric capacity Cr With resistance Rr, described inductance Lr, electric capacity Cr, resistance RrSeries connection, as it is shown in figure 1, tuning filtering device is in order to quenching frequency component Form a low-impedance resonance path, fundametal compoment is formed a high resistant branch road simultaneously.Owing to tuning filtering device is one humorous Shake circuit, in the ideal case, as long as the inductance then in this wave filter and capacitance meet condition of resonance, but tuning filtering Device is providing while low impedance path for quenching frequency component, it should can the existence of Fundamental wave suppression component to greatest extent, i.e. Fundametal compoment is formed a impedance the highest.
(1) making DC voltage is Vc, making maximum exchange power is Pemax, according to resistance RrWith Vc、PemaxRelation determine Rr, formula is:
P e m a x = V c 2 4 R r ;
(2) any ω of diagonal frequencies, the resistance value of tuning filtering device branch road can be expressed as:
Z r = R r + jL r ( ω - ω a 2 ω )
Wherein, ωa=2 π faFor resonance angular frequency.
Because the resistance R in tunable filter circuitrRelatively the least for reactance, thus from the above it can be seen that tuning filtering device props up The resistance value on road is mainly determined by its inductance value, and the impedance that this branch road is when fundamental frequency and quenching frequency is all along with inductance Value LrIncrease and increase.
Making resonant frequency is fa, making resonance angular frequency is ωa, making fundamental frequency is fm, making first-harmonic angular frequency is ωm, make base The loss value of frequency part is Ploss_m, the lower limit making inductance is Lr_low, make the tuning filtering device impedance angle when first-harmonicRoot According to power attenuation value and the formula of first-harmonic, calculate the lower limit L of described inductancer_low, formula is:
Wherein, MhIt is maximum fundamental modulation degree in three H bridge modules, ωm=2 πfm, ωa=2 π fa；
Consider iff from tuning filtering device branch road in the loss of first-harmonic part, then its inductance value LrThe biggest, it damages Consume the least.
On whole circuit impedance and the impact of electric current, two kinds of differences are chosen in order to analyze different induction value in tuning filtering device Tuning filtering device parameter, and its simulation result is compared, two kinds of parameters are as shown in the table:
Simulation result is as shown in Figures 2 to 4.
As can be seen from Figure 4, feelings when tuning filtering device variance of current ratio in the case of small capacitances is significantly less than bulky capacitor Condition.So selecting small capacitances to be conducive to taking into account the realization of tuning and LC filter filtering function.
But on the other hand, the quality factor of resonance circuitAnd resonant branch inductance and the electricity at electric capacity two ends It is pressed with following relation: UL(j ω)=UC(j ω)=QUi(j ω), namely when in tuning filtering device electric capacity the least, when inductance is the biggest, Quality factor are the highest, and now inductance capacitance two ends will appear from comparing UiExceed the overvoltage of Q times.
(3) simultaneously, from the standpoint of another, there will necessarily be certain error at actually used inductance capacitor, and Can be along with the change of external environment (as used temperature etc.), also can there is certain skew in design parameter, the existence of above-mentioned error, Inherently the correct work to tuning wave filter affects.
The higher limit making inductance is Lr_high, making inductance side-play amount is Δ L, makes the acceptable angular deviation beOrder is adjusted Humorous filter branches is Z in the practical impedance of quenching frequency partrr, according to Δ L and Zrr、Rr、ωaRelation calculate Δ L, and then According to described Lr_lowWith higher limit L that Δ L calculates inductancer_high, formula is:
Lr_high=Lr_low+ΔL；
The electric current of tuning filtering device branch road is represented by
For the phase angle of the equivalence output quenching frequency voltage of energy storage converter unit, Vah=Vc,
Knowable to above formula, the skew of resonant inductance can cause the phase offset of quenching frequency electric currentAnd its amplitude is also Can reduce accordingly.Thus, three H bridge module DC side power supply E1～E3The power of exchange also will offset theoretical value, in some instances it may even be possible to Deviate from the design object of required exchange completely.Such as, the 3rd H bridge module DC side power supply E3The active power of output may From 0～P3.Wherein P3For
When the inductance value side-play amount of tuning filtering device is ± 2%,Can be by reducing inductance LrOr increase resistance Value RrMinimize.RrDetermine the size of exchange power, SOC balance speed and power attenuation.RrIncrease will weaken SOC Balance route runs and efficiency.And meanwhile, reduce inductance LrThe fundamental component in tuning filtering device branch road will be increased.Should In branch road, the increase of fundamental frequency voltages and electric current can affect the operational efficiency of whole system equally.Thus, in tuning filtering device branch road Inductance and the design of resistance should consider the control accuracy of system and the loss of whole system.
(4) finally according to the L calculatedr_lowAnd Lr_high, select Lr, make Lr_low≤Lr≤Lr_high, according to described LrMeter Calculate electric capacity CrValue, formula is:
ω a L r = 1 ω a C r .
The ultimate principle of the present invention, principal character and beneficial effect and embodiment have more than been shown and described.The present invention It is the method for designing of tuning filtering device based on subring energy-storage system Power Exchange, for the design side of other similar wave filter Method falls within scope.
