Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiments only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiments of the present invention relate to a kind of control gear of optimizing tidal power generation, as shown in Figure 1, comprise master controller, electromagnetism field plate, magnetic field detector, energy detector, at least 2 moving floats and at least 2 the trickle processing circuits that formed by dsp chip and fpga chip.Master controller comprises electromagnetism field plate control port and the synthetic control and management port of energy.Moving float is floating across the sea, wherein, each moving float all is connected with a trickle processing circuit, links to each other with the input end of energy detector after each trickle processing circuit is connected mutually, and the output terminal of energy detector links to each other with the synthetic control and management port of the energy of master controller.The electromagnetism field plate is positioned at the top of moving float, and links to each other with the electromagnetic field control port.Magnetic field detector is positioned at a side of electromagnetism field plate, and links to each other with the magnetic field detection port.Wherein, the master controller that is formed by dsp chip and fpga chip be mainly used to generate an electromagnetic field panel area electromagnetic field, detect magnetic direction and energy and the generated energy that the trickle processing circuit of series connection produces carried out dynamic monitoring.Dsp chip produces the PWM modulation signal, produce power voltage, thereby the electromagnetism field plate is provided the energy of converts magnetic field, this power voltage flows to the electromagnetism field plate by electromagnetism field plate control port, thereby make the electromagnetism field plate that electric power signal is converted to magnetic field energy, can pass through direction and the size in the magnetic field of magnetic field detector detection of electromagnetic fields plate generation this moment.The moving float that is positioned on the sea is subjected to displacement with the fluctuation of seawater, and this moment is under the magnetic fields that the electromagnetism field plate produces, because the Faradic electricity magnetic induction principle, moving float can produce induced potential, and the induced potential that produces is sent into the trickle processing circuit.The trickle processing circuit is processed the voltage of alternation, thereby forms VDC, the VDC that forms is being stored again.Thereby each trickle processing circuit connected consist of voltage and the energy of stack, and with link to each other by the synthetic control and management port of the energy of energy detector and master controller, carry out analog-to-digital conversion by dsp chip and fpga chip, thereby it is carried out control and management.
Shown in Figure 2 is the schematic diagram of trickle processing circuit.Wherein, comprise rectification circuit, trickle charge chip, voltage feedback circuit and energy-storage travelling wave tube.The input end of rectification circuit links to each other with moving float, and output terminal links to each other with the input end of trickle charge chip, and the output terminal of trickle charge chip links to each other with energy-storage travelling wave tube, and voltage feedback circuit is connected on the Voltage Feedback port of trickle charge chip.Rectification circuit adopts bridge rectifier, because the alternating voltage that moving float provides is unsteady and unsettled, the frequency of alternating voltage is consistent with the kinetic energy frequency of this moving float, therefore adopts bridge rectifier to control better.Energy-storage travelling wave tube adopts that charging rate is fast, long service life, discharge capability is strong and conversion efficiency is high super capacitor.The trickle charge chip adopts the LTC3105 chip, and the Processing capacity of its voltage is between 0.2V～5V.The design of voltage feedback circuit mainly is in order to provide the charging voltage of setting.
The present invention produces the PWM modulation signal by dsp chip first in use, produces power voltage and is transferred to the electromagnetism field plate, and the electromagnetism field plate transfers it to magnetic field energy after receiving power voltage, thereby forms magnetic field around it.Because moving float is below the electromagnetism field plate, when seawater fluctuation, moving float can produce induced potential, and the induced potential that produces when nearest from the electromagnetism field plate is maximum, and the induced potential of generation is used for offering the trickle processing circuit.Wherein the induced potential that produces of induction is alternating voltage, so this alternating voltage is converted into VDC by the trickle processing circuit, and by the trickle charge chip super capacitor as energy-storage travelling wave tube is charged.Owing to moving float floats, the VDC that therefore produces is also floated, and the VDC of each trickle processing circuit is relatively independent, therefore under the effect of the trickle processing circuit of connecting, can provide a metastable Voltage-output.
Along with the variation of the variation of morning and evening tides or wave adds up the energy that all trickle circuit of unit time converge by energy detector, the accumulated value of electric energy is decided to be PW
1, PW
2, PW
3..., PWi, PW
I+1, after the energy of master controller synthesizes the accumulated value of control and management port processing to a setting, just change the direction in magnetic field, be PW at the energy that collects namely
1The time, change magnetic direction; Be PW at the energy that collects
2The time, change again magnetic direction, by that analogy.So just can in system, establish the power diagram take magnetic direction as abscissa, then, judged the maximum value of electric weight by master controller, the direction that the stable magnetic field of whole device is produced in the electric weight maximum value, like this, system just can be in the generated energy of power generation system the state of optimization all the time, and namely generating efficiency is the highest.The condition of above-mentioned selection is the maximization that generated energy can satisfy gatherer process, from general, is whole power generation process to be in the transfer process of an optimum, and then makes system obtain the highest efficient.But the foundation of electromagnetic field is to need power consumption, and system also will monitor another variable: the magnetic field energy consumption.The magnetic field energy consumption detects by magnetic field detector.When the difference of the generated energy that obtains and magnetic field energy consumption during less than the threshold epsilon of setting, (ε can arrange arbitrarily), at this moment, whole device will enter state of dormancy, so that the overall energy consumption of whole device is minimum.
Be not difficult to find that the present invention is exactly the Wave energy that has utilized seawater, but with the electric energy gap, unsettled by energy-storage system with its cumulative electric weight that becomes stable power supply network scheduling.The trickle processing circuit of utilization process series connection is kept at the Wave energy of seawater in the super capacitor energy-storage circuit of unit body, to supply with jumbo accumulator device.Simultaneously by changing automatically controlled mode, the direction by regulating magnetic field is so that the electric energy maximization of conversion, and the foundation in magnetic field is according to outside variation and changing, and finally makes the conversion efficiency of generating the highest.
