Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings.
See Fig. 1, the invention discloses a kind of V2G direct current bidirectional energy-storage current transformer, adopt including two-way current conversion circuit, information
Collector and control system, described two-way current conversion circuit includes the brachium pontis of three settings parallel with one another, the upper brachium pontis of each brachium pontis
Power switch pipe T1, T2, T3, T4, T5 and the T6 being provided with backward diode D, such as corresponding IGBT mould is all used with lower brachium pontis
Block, the upper end of each described brachium pontis is connected with each other, and can connect dc bus positive pole, each institute by dc bus positive terminal
The lower end stating brachium pontis is connected with each other, can by dc bus negative terminal connect dc bus negative pole, each brachium pontis and
Corresponding power side inductance L1, L2 and L3 constitute an independent unsteady flow branch road, and each unsteady flow branch road is parallel with one another, and both sides share
Same bus bar side electric capacity C1 and mains side electric capacity C2, is positioned at mains side positive terminal and the negative terminal of mains side
May be respectively used for connecting the power supplys such as energy-storage battery.
Control system for convertor circuit control can control the on off state of each switch element, at different switch shapes
Under state, it is possible to achieve the two-way conveying of electric energy, the electric energy of power supply is delivered to dc bus, can be the use being connected to dc bus
Electricity sets offer electric energy, and the electric energy of dc bus is delivered to power supply, can be power source charges.
Described information acquisition circuit gathers the various electric currents in convertor circuit and information of voltage, in order to control system carries out phase
Close and control, owing to control system is beneficial to total system and the situation of each relevant device thereof to the control of electric energy conveying direction, because of
This, it is also possible to the circuit being used for acquisition system coherent signal is considered as a part for described signal acquisition circuit, described information
The signal output of Acquisition Circuit accesses described control system, and control system by being analyzed calculating, Jin Ersheng to relevant information
Become and send corresponding control signal, controlling the on off state of each described power switch pipe, regulate in the circuit of described current transformer
Described current transformer two ends are carried out determining Control of Voltage by the flow direction of electric current.
The output of three unsteady flow branch roads makes the current capacity of convertor circuit improve three times, by controlling three unsteady flow branch roads
The switch time of upper switch element, make interlaced 120 ° of three output waveforms paid, by three tunnel output waveforms (usually
Sawtooth waveforms) staggered superposition, can be substantially steady with waveform, total current ripples amplitude drops significantly relative to the ratio of Equivalent DC
Low, make the equivalent switching frequency of circuit expand original three times to, and ripple frequency also increase to original three times thus more
Filtering well, also reduce the capacity requirement to mains side inductance simultaneously, make under equal unsteady flow capacity, the volume making inducer is big
Big reduce, and be used as the switching frequency of the power electronic devices of switch element without the highest, thus significantly reduce switch
Loss.
Described control system can be provided with central processing unit and interlock circuit, such as interface circuit and output control circuit,
Described output control circuit can use PWM to drive control circuit.
When current transformer carries out No Load Start, if according to PI parameter starting device time properly functioning, then scale parameter P mistake
Change in duty cycle will be caused greatly too fast, and then it is too fast to cause electric current to rise, switch element can send ear-piercing sound, and impact is opened
Close component life, even switch element is caused damage.Therefore, soft opening is carried out when No Load Start first with suitable PI parameter
Dynamic, the startup time of equipment is about 1s, when adjust after voltage reaches setting value PI parameter be equipment properly functioning time value, thus
It is more beneficial for stable operation and the quickly response of equipment.
Fixed voltage-controlled target is to maintain stablizing of outlet side voltage, ensure simultaneously inverter inside do not occurred stream and
The current balance type of three brachium pontis (branch road), therefore when carrying out closed loop control, needs add current inner loop in the inside of Voltage loop,
Realizing controlling the two close cycles PI of current transformer, its control principle is as in figure 2 it is shown, wherein UrefFor dc bus reference voltage, UdcFor
Dc bus virtual voltage, IrefFor flowing through the current reference value of three road electric currents of each brachium pontis, Ia、Ib、IcIt is respectively three road electric currents
Value, Da、Db、DcDutycycle for each brachium pontis.In relevant drawings, the reference current of three road electric currents of display is identical, and three brachium pontis
Interlaced 120 ° of PWM carrier wave, thus identical sized by three road electric currents, the sawtooth waveforms of phase cross-over.
In real work, the collection of signal generally requires link after filtering, adds two close cycles PI control itself
Response speed is relatively slow, and therefore when DC load generation large change, DC bus-bar voltage can produce when falling more greatly and reply
Between relatively long, the scale parameter P simultaneously increasing internal ring and outer shroud can improve the response speed of inverter, but transports in reality
In row, scale parameter (especially internal ring scale parameter) is crossed conference and is caused inverter dutycycle bigger ripple at steady state
Move, and then cause the big ups and downs of inverter inside electric current, affect inverter steady-state characteristic.Add feedforward link can have
The voltage pulsation caused during effect suppression load switching, when loading change and causing outlet side capacitance voltage to produce larger fluctuation, electricity
Pressure departure will result directly in the change of internal ring reference current, thus increases the response speed of current inner loop.This feedforward
Link, without departing from current inner loop, is not result in that when load changes three road electric currents of inside are excessive.Transport in equipment stable state
During row, often it is not intended to start feedforward, therefore can add dead band link in feedforward link, only produce relatively greatly partially at voltage
Feedforward is started during difference.
When not having under conditions of communication to realize the operation of many equipment coordinations, the internal ring that described two close cycles PI controls controls still
Can according to or determine voltage control method with reference to aforesaid, outer loop control method then uses droop control method, described sagging control
The method of system is: described central processing unit controls three road electric current outputs according to the electric current sagging curve set and DC bus-bar voltage
Intensity, maintain the stablizing of DC bus-bar voltage.The schematic diagram of described droop control as it is shown on figure 3, wherein,For energy storage electricity
Pond busbar lateral capacitance voltage,For DC master row voltage,For energy-storage battery to the electric current of direct-current grid input/output,For energy-storage battery to the reference current of direct-current grid input/output,For the filter inductance of outlet side,For load-side etc.
Effect resistance.
Above-mentioned droop control relates toWithDroop characteristic as shown in Figure 4, wherein IcmFor maximum discharge current,
IctFor constant-current charge electric current, IdcmFor maximum charging current.Variable quantity according to DC voltage () can be by lower whip
Line is divided into three parts, and the threshold voltage choosing voltage layering switching point in Fig. 4 is respectively 0.02 and 0.05, for droop control
Stability controller, according to the sagging curve of program setting, exports phase induced current according to DC bus-bar voltage, thus realizes direct current
Stablizing of busbar voltage.
