Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment 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 energy-storage system of tidal power generating device, as shown in Figure 1, comprise master controller, electromagnetism field plate, at least 2 moving floats and at least 2 trickle treatment circuits of being comprised of 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, and wherein, each moving float all is connected with a trickle treatment circuit across the sea, is connected with the synthetic control and management port of energy after each trickle treatment circuit is connected mutually.The electromagnetism field plate is positioned at the top of moving float, and is connected with the electromagnetic field control port.Wherein, the master controller that is formed by dsp chip and fpga chip be mainly used to the to generate an electromagnetic field electromagnetic field of panel area and the trickle treatment circuit of series connection is carried out energy measurement.Dsp chip produces the PWM modulation signal, produces power voltage, thereby the electromagnetism field plate is provided the energy of converts magnetic field, and this power voltage flows to the electromagnetism field plate by electromagnetism field plate control port, thereby makes the electromagnetism field plate that electric power signal is converted to magnetic field energy.The moving float that is positioned on the sea is subjected to displacement with the fluctuation of seawater, and this moment, due to the Faradic electricity magnetic induction principle, moving float can produce induced potential under the magnetic fields that the electromagnetism field plate produces, and the induced potential that produces is sent into the trickle treatment circuit.The trickle treatment circuit is processed the voltage of alternation, thereby forms direct voltage, then the direct voltage that forms is being stored.Consist of voltage and the energy of stack thereby each trickle treatment circuit is connected, and be connected with the synthetic control and management port of energy dsp chip and fpga chip carry out analog-to-digital conversion, thereby it is managed.
Shown in Figure 2 is the schematic diagram of trickle treatment circuit.Wherein, comprise rectification circuit, trickle charge chip, voltage feedback circuit and energy-storage travelling wave tube.The input of rectification circuit is connected with moving float, and output is connected with the input of trickle charge chip, and the output of trickle charge chip is connected 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, and the alternating voltage that provides due to moving float is unsteady and unsettled, and 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 disposal ability of its voltage is between 0.2V～5V.The design of voltage feedback circuit is mainly in order to provide the charging voltage of setting.
The present invention first produces the PWM modulation signal by dsp chip 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.Below the electromagnetism field plate, when seawater fluctuation, moving float can produce induced potential due to moving float, 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 treatment circuit.Wherein the induced potential that produces of induction is alternating voltage, so this alternating voltage is converted into direct voltage by the trickle treatment circuit, and by the trickle charge chip, the super capacitor as energy-storage travelling wave tube is charged.Because moving float floats, the direct voltage that therefore produces also floats, and the direct voltage of each trickle treatment circuit is relatively independent, therefore under the effect of the trickle treatment circuit of connecting, can provide a metastable Voltage-output.
Be not difficult to find, the present invention is exactly the Wave energy that has utilized seawater, becomes the electric weight of stable power supply network scheduling but the electric energy gap, unsettled is added up it by energy-storage system.The trickle treatment 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.
