Description

Technical Field

[0001] The present invention relates to the field of power management technology, and more specifically, to a smart grid energy management device and method thereof. Background Art

[0002] Smart grid energy storage management equipment has the function of peak shaving and valley filling, which can effectively realize demand-side management, eliminate the peak and valley differences in electricity demand during the day and night and in different seasons, and increase the daily load rate of the power system, thereby improving the utilization rate of power generation equipment and reducing the cost of energy storage power supply.

[0003] In the existing public documents, the patent publication number CN116436161A discloses a power data management system applied to smart grids. The existing inverters mostly rely on heat dissipation holes or heat dissipation fans to dissipate heat during use. The use of heat dissipation fans causes a waste of energy at low temperatures during use, and the use of heat dissipation holes causes a large amount of dust to be adsorbed inside after long-term use. This patent uses a heat dissipation fan in combination with an electrode sheet and mercury to enable the device to work according to the internal temperature during use. When the internal temperature reaches a critical point, the electrode sheet contacts the conductive sheet, thereby making it pass through. The device effectively ensures the heat dissipation effect of the device during use, and can reduce the internal energy damage according to the control of its temperature. The following defects exist:

[0004] When the grid energy management device is used for management, the excess electric energy is stored in the energy battery and supplied to the grid circuit when needed. Once the current and voltage are abnormal, the charger needs to be cut off to avoid continuous charging and damage to the energy storage battery. The energy storage battery is disconnected by the circuit breaker alone. Once the circuit breaker is damaged, it will continue to charge, which greatly reduces the safety of energy management.

[0039] Working principle of the smart grid energy management device of the present invention:

[0040] First, when the present invention is used for power supply, the two power supply terminals 16 are connected to the mains, and the charging time of the energy storage is set through the touch management screen 20. After the set time is reached, the circuit breaker 14 is opened by the controller on the touch management screen 20, and power is supplied to the connection terminal 13 through the power supply terminal 16, and then the connection terminal 13 supplies power to the charger 12. The charger 12 transmits the electric energy to the charger connecting line 11, and the charger connecting line 11 transmits the electric energy to the charging terminal 9 so that the on-off terminal 8 supplies power. The on-off terminal 8 supplies power to the charging harness 10 to the storage battery 2, and stores it inside the storage battery 2. When power is needed, the storage battery 2 is opened to supply power to the output power supply terminal 22, and the power supply management of the power grid energy storage is completed, and then the current and voltage values ​​of the operation are displayed through the current and voltage display meter 19;

[0041] Secondly, when the present invention performs a first-level circuit breaker calibration, the current and voltage values ​​of the power supply are detected by the current and voltage detector 15 for the connection terminal 13. Once the current and voltage values ​​exceed the specified voltage and current values, the circuit breaker 14 is started to break the circuit through the touch management screen 20. When the circuit breaker 14 is not disconnected, and the current and voltage values ​​sensed by the current and voltage detector 15 are still abnormal, the touch management screen 20 starts the reduction drive motor 17 to drive the linkage disconnecting screw 4 to rotate forward inside the support frame plate 3. The linkage disconnecting screw 4 drives the first thread linkage sleeve 5 to move to the left under the action of the thread, and the second thread linkage sleeve 6 moves to the right along the inside of the support frame plate 3. The two linkage insulating plates 7 respectively drive the chain of each on-off terminal 8 to move, and the on-off terminal 8 moves and separates from the charging terminal 9, so that the on-off terminal 8 is disconnected from the charging terminal 9, and the linkage insulating plate 7 drives the second pressure sensor 34 to move. The second pressure sensor 34 is squeezed on the fixed support block 35. When the pressure value is sensed, the reduction drive motor 17 is turned off through the output power supply terminal 22.

[0042] Finally, when the present invention performs secondary calibration, when the second pressure sensor 34 does not contact the fixed support block 35 to generate pressure, and the timing switch 21 does not receive a pressure signal within the specified time, the reduction motor 30 is started by touching the management screen 20 to drive the transmission screw 29 to rotate inside the guide slide 33, and the transmission screw 29 drives the threaded sleeve linkage support block 28 to move upward along the guide inside the guide slide 33 under the action of the thread, and the threaded sleeve linkage support block 28 drives the two first support blocks 27 to move upward, and the first support block 27 drives the linkage shaft 26 to move the first support block 27 upward, and the first support block 27 drives the linkage shaft 26 to move the sleeve articulated frame 25 upward, and the sleeve articulated frame 25 drives the sliding support 24 to move, and the two sliding support 24 are close to each other along the inner wall of the guide slide frame plate 23, and the sliding support 24 drives the charging terminal 9 to move, and the two charging terminals 9 move close to each other, and the charging terminal 9 can be separated from the on-off terminal 8 for secondary calibration, forming a secondary automatic induction separation to disconnect the abnormal charging circuit, and the management safety of the storage battery 2 is effectively improved during charging.

[0043] Based on the above embodiments, the present invention further provides a smart grid energy management method, which includes the following steps:

[0044] Step 1: When the energy storage is used for power supply, the storage battery 2 is charged by the charger 12, and after charging, the storage battery 2 transmits energy to the power grid;

[0045] Step 2: Perform a first-level calibration circuit breaker. When the circuit breaker 14 is damaged and cannot be disconnected, the charging terminal 9 and the on-off terminal 8 are disconnected through the calibration linkage disconnection mechanism.

[0046] Step three, perform secondary calibration. When the primary calibration circuit breaking is not completed, the calibration separation component performs secondary calibration and completes the circuit breaking to achieve safety management of the storage battery 2.

[0047] Technical effects and advantages of the present invention:

[0048] 1. The present invention uses a calibration linkage disconnection mechanism to detect the current and voltage values ​​of the power supply to the connection terminal through a current and voltage detector. When the circuit breaker is not disconnected, the reduction drive motor is started to drive the linkage disconnection screw to rotate forward inside the support frame plate. The linkage disconnection screw drives the first thread linkage sleeve block to move to the left under the action of the thread, and the second thread linkage sleeve block moves to the right along the inside of the support frame plate. The on-off terminal moves and separates from the charging terminal, so that the on-off terminal and the charging terminal are disconnected, and the circuit breaker that is not disconnected can be calibrated in time to ensure that the connection terminal can automatically calibrate the abnormal current and voltage when charging the storage battery to realize intelligent linkage disconnection, and completely disconnect to avoid continuous charging, thereby greatly improving the safety of energy management;

[0049] 2. The present invention uses the calibration separation component to make the second pressure sensor not contact the fixed support block to generate pressure, and at the same time the timing switch does not receive the pressure signal within the specified time, the reduction motor is started to drive the transmission screw to rotate inside the guide slide, the threaded sleeve linkage support block drives the two first support blocks to move up, the first support block drives the linkage shaft to move the first support block up, the sleeve articulated frame drives the sliding support to move, the two sliding supports approach each other along the inner wall of the guide slide frame, the charging terminal can be calibrated and separated from the on-off terminal for the second level, and the first circuit breaker can be calibrated and sensed after the pressure, and then automatically started to form a second-level linkage disconnection circuit, ensuring that after the first level is not disconnected, the second level can continue to disconnect the charging circuit of the charger and the storage battery, thereby improving the energy charging safety;

[0050] 3. The present invention adopts a detection and calibration component. When the current and voltage values ​​sensed by the current and voltage detector are still abnormal, the reduction drive motor is started to drive the linkage disconnect screw to rotate forward inside the support frame plate. When the pressure value is sensed, the reduction drive motor is turned off through the output power supply terminal. When the second pressure sensor does not contact the fixed support block to generate pressure, and the timing switch does not receive the pressure signal within the specified time, the reduction motor is started to drive the transmission screw to achieve driving. In this way, both the first-level linkage disconnection and the second-level linkage disconnection can be driven according to the intelligent sensor, so as to realize intelligent and accurate disconnection of the circuit, ensuring that the charger is disconnected in time when the storage battery charging circuit is abnormal;

[0051] Among the mutual influences of the above-mentioned multiple effects, firstly, the proofreading linkage cutting mechanism can be used to timely proofread and disconnect the circuit breaker that has not been disconnected, and then the charging terminal can be used to perform secondary proofreading and disconnection with the on-off terminal, and finally, the primary linkage disconnection and the secondary linkage disconnection can be used to disconnect the circuit according to the intelligent sensor drive. In summary, when the charger and the storage battery are charging, a secondary linkage disconnection circuit can be formed to ensure that the energy charging circuit is disconnected in time when an abnormality occurs, and the safety of power grid energy management is effectively improved.
