As to further improvement of the utility model, hybrid filter includes active power filter APF and through supergroup filter TSF, use controlled thyristor as controlling capacitor and the switch of reactor, capacitor and reactor can be carried out various combination, when changing by electric unit, can be analyzed according to the characteristic of monitoring signal and calculate, sum up the filtering combination of optimum, control effect is made to reach optimum, this hybrid filter combines active and passive filter advantage, and the raising to Power System Performance has preferably effect.
In the hardware configuration of hybrid filter, through supergroup filter TSF part is the capacitor that controls of controlled thyristor GTO or IGBT and the filtering of reactor composition and reactive power compensation circuit, by controlling opening and closing of IGCT, adjust the structure of through supergroup filter TSF.From with electrical network and load attachment structure in terms of, the compensation device of whole system substantially parallel connection type, wherein, low-order harmonic and reactive power that energy is bigger are mainly compensated by through supergroup filter TSF, the Main Function of Active Power Filter-APF APF is suppression residue harmonic wave, and improves the filter characteristic of through supergroup filter TSF.
Hybrid filter uses detection load current and the composite control method of detection mains by harmonics electric current.Wherein, main making electric current essentially from load current, available preferable harmonic suppression effect, detection mains by harmonics electric current is then primarily to prevent contingent resonance between passive device and electrical network.Assume that Active Power Filter-APF APF is a preferable controlled voltage source UC(UC=KSISh+KLILh, ISh、ILhIt is respectively grid side electric current and the harmonic component of load-side electric current), load harmonic source is considered as a current source IL, ZSFor source impedance, ZTImpedance for through supergroup filter TSF.When not being connected to active power filter, load harmonic current IShBeing compensated by through supergroup filter TSF, its compensation characteristic depends on ZSAnd ZTIf, source impedance the least (| ZS| ≈ 0), or through supergroup filter TSF be not tuned to load produced harmonic frequency (| ZT|>>|ZS|), just do not reach required filtering characteristic, especially work as ZSWith ZTAt characteristic frequency occur parallel resonance time (| ZT+ZS| ≈ 0), will appear from Harmonics amplification phenomenon, flow into source current bigger than load harmonic current.Access Active Power Filter-APF APF, and control it as voltage source, i.e. a UC=KSISH+KLILH1., now, the harmonic current forced in load is flowed into through supergroup filter TSF by Active Power Filter-APF APF, make in source current without harmonic wave, by 1. formula it can also be seen that Active Power Filter-APF APF is not subject to fundamental voltage, this makes the capacity of Active Power Filter-APF APF the least.Use composite control method, by suitable control KSAnd KL, both can suppress load harmonic current, contingent resonance between electrical network and passive device can have been suppressed again；And two control coefrficient KSAnd KLIt is full decoupled, therefore, it can as required two coefficients be carried out completely self-contained control, thus obtain satisfied control effect.
The passive filter of low cost is the most commonly used reactive-load compensation and harmonic treating apparatus, and this device uses simple, but there is certain defect.Harmonic wave and the idle of change that amplitude and frequency can all be changed by active filter compensate, but there is also the shortcoming that initial investment is big, operational efficiency is low.To this end, active filter and passive filter are used in combination with, active filter capacity both can be made to reduce, the defect of passive filter can have been made up again, be a good harmonic treating apparatus.
Incorporate the charging pile Special box-type substation of hybrid filter, can effectively administer and eliminate from charging pile and from the multiple harmonic of system, reduce harmonic pollution and improve power factor of electric network, thus substantially increasing the quality of power supply of power system.
