Description

Technical Field

[0001] This disclosure relates to the field of power system technology, and in particular to a load forecasting terminal device for distribution networks with distributed generation access. Background Technology

[0002] With the development of power systems, technologies such as automatic control, electronics, and computer communication have been widely applied in power distribution equipment. Currently, load control terminals are used for real-time monitoring of electricity consumption, enabling effective peak-shaving. As automated devices for real-time monitoring of user electricity consumption, overload control, and peak-shaving restrictions, load control terminals play a crucial role in the orderly use of electricity and the stable operation of the power distribution network. Developing load control terminals using high-performance integrated chips and advanced technologies to accurately measure power load in real time and accurately reflect the status of power distribution lines is of great significance. However, most load control terminals currently on the market only accept input data before control, and cannot be modified on-site.

[0003] According to the patent document CN218040921U, a smart load control terminal for a source-grid-load-storage system includes a mounting box, a control terminal body, and a positioning component. One side of the mounting box is open, and fasteners are installed inside the mounting box. The control terminal body is fixedly installed inside the mounting box by the fasteners. An extension plate is fixedly installed on the lower side of the mounting box, and a constraint component for positioning the cabling is provided on the side of the extension plate. The positioning component includes a fixing plate and a positioning rod. The positioning rod is fixed to the side of the fixing plate. An annular plate is fixed to the side of the mounting box, and the annular plate is slidably sleeved on the outside of the positioning rod. A fastening bolt for positioning is threadedly connected to the side of the annular plate. This technical solution... During use, its position is adjustable, facilitating the replacement and maintenance of other electrical components within the electrical cabinet. Adjusting the position of the control terminal also allows for easy observation of the information displayed on it, and the wiring connected to the control terminal can be secured to prevent it from becoming detached during movement. A protective device is installed on the outside of the control terminal to prevent damage from collisions with other electrical equipment during disassembly or maintenance. However, while this technical solution mitigates damage from collisions to the control terminal, it lacks the ability to quickly adjust the installation location within the available space. Furthermore, once the equipment is fixed in place, it cannot effectively limit and secure the internal control terminal, resulting in inconvenience during use. Summary of the Invention

The slider is movably installed inside the groove through a support mechanism, and a cable is movably installed inside the mounting hole.

[0013] Optionally, a fixing plate is fixed to one end of the limiting post, a reset mechanism is fixedly installed between the fixing plate and the fixing ring, and a protruding ring is welded to the inner wall of the support tube, the protruding ring cooperating with the fixing ring.

[0014] Optionally, a clamping plate is movably installed inside the movable box. The clamping plate is fixedly installed at one end of the limiting post. A groove is opened inside the clamping plate, and a prediction terminal is movably installed inside the groove.

[0016] The technical solution provided in this disclosure may include the following beneficial effects: This invention involves installing a fixed box inside a control cabinet or other space, with a support base rotating on the fixed box. The mounting plate rotates on the support plate via a connecting seat to adjust the installation angle. By tilting the support base, the width of the installation point can be adjusted according to the size of the installation space. In addition, rotating the support base allows the limiting plate to enter the bottom of the fixed box. The limiting plate and the support base work together to complete the vertical ground installation and fixation of the fixed box, meeting the adjustment and use requirements under different conditions. After the support base and mounting plate are fixed, the movable box moves up and down. As the movable box moves up and down, the positioning column moves inside the positioning tube through the connecting block. The positioning tube rotates on the fixed column through the bushing to change the angle between it and the fixed plate. After the movable box moves up and down, the internal prediction terminal is controlled. When not in use, the movable box slides inside the fixed box for shielding and protection to avoid damage to the movable box caused by external collisions. The limit seat on the top of the movable box limits the movable box and rotates on the heat dissipation component. The cleaning brush on the inner wall of the limit seat scrapes and cleans the surface of the heat dissipation component. This invention installs the cable inside the limiting ring and uses compression bolts to compress and fix the cable. Before fixing the cable, the top cable provides a suitable length for the movable box to move up and down. When the movable box or other directions pull the cable, the cable drives the limiting ring to swing up and down inside the fixed tube for buffering and vibration reduction, thereby avoiding damage to the cable caused by external force. In addition, while the fixed tube realizes cable management, the limiting ring moves up and down through the support mechanism to facilitate the rapid retraction and return of the moved cable to its original position, which is convenient for later storage.

The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] like Figures 1 to 9 As shown, the distribution network load forecasting terminal device with distributed power supply access includes: a fixed box 1, the fixed box 1 having an internal cavity 3, a movable box 4 movably installed inside the cavity 3, a fixing plate 9 welded to the side of the movable box 4, an opening 8 on the side of the fixed box 1, and the fixing plate 9 movably installed inside the opening 8; and a fixing assembly 19, the fixing assembly 19 including a fixing pipe 27, a support rod 25 welded to the side of the fixing pipe 27, a fixing hole 26 on the top of the support rod 25, and the support rod 25 being fixedly installed in the fixed box 1 through the fixing hole 26. Side; limiting component 21 and support component 22, the limiting component 21 and support component 22 are fixedly installed on the side of the movable box 4, the limiting component 21 and support component 22 each include support tube 40, the support tube 40 is movably installed with extrusion column 41 and limiting column 45 inside, one end of extrusion column 41 is fixed with fixing ring 42. This device is suitable for power supply such as AC power transmission above 750 kV, large-scale power grid security and defense system and intelligent dispatch system, for power supply or distribution circuit devices or systems, energy storage system, and circuit devices that provide remote indication of network status.

[0022] In this embodiment, a heat dissipation assembly 6 is fixed to the top of the movable box 4. The heat dissipation assembly 6 includes a mounting cavity, inside which an exhaust fan and a filter plate are fixedly installed. The filter plate is fixedly installed on the top of the exhaust fan, and a limiting seat 7 is movably installed on the filter plate. A fixing seat 11 is welded to the side of the fixed box 1. A support seat is movably installed on the side of the fixing seat 11. A connecting seat 16 is movably installed between the support seats. A mounting plate 17 is welded to one end of the connecting seat 16. A limiting plate 18 is welded to the side of the mounting plate 17. A fixing column 15 is fixedly installed between the support seats. A bushing 14 is rotatably installed on the fixing column 15. A positioning tube 13 is fixed on the bushing 14. A positioning column 12 is movably installed inside the positioning tube 13. A fixing frame 10 is welded to one end of the positioning column 12. The fixing frame 10 is movably installed on the fixing plate 9. A tension spring is fixedly installed between the positioning tube 13 and the positioning column 12. The inner wall of the cavity 3 has a slot 5 and a fixing slot 24 respectively. The limiting component 21 is movably installed inside the slot 5, and the supporting component 22 is movably installed inside the fixing slot 24. A cover plate 23 is movably installed on the side of the movable box 4. An observation window 2 is fixed on one side of the fixed box 1. The observation window 2 cooperates with the cover plate 23. When the movable box 4 moves up and down, the fixing plate 9 pulls the positioning column 12 through the fixing bracket 10. After the positioning column 12 is pulled, it moves inside the positioning tube 13. The tension spring inside the positioning tube 13 is stretched and deformed. The stretched tension spring generates a rebound force. Later, under the drive of the rebound force, it is easy to make the movable box 4 return to its position, or under the limit of the tension spring, the movable box 4 is always limited to the inside of the fixed box 1 for use.

[0023] In this embodiment, a baffle 36 is welded to the inner wall of the movable box 4, and the cover plate 23 is mounted on the movable box 4 via a torsion spring shaft. The baffle 36 cooperates with the cover plate 26 to provide a seal. The fixed tube 27 has an installation hole 28 inside, and a ring seat 29 is movably installed on the side of the fixed tube 27. A compression bolt 30 is rotatably installed on the ring seat 29. A limit groove 31 is opened on the fixed tube 27, and a limit block 32 is movably installed inside the limit groove 31. One end of the limiting block 32 is fixed to the inner wall of the ring seat 29, and the other end of the limiting block 32 is welded with a limiting ring 33. A slider 34 is fixed to the side of the limiting ring 33. A groove is opened on the inner wall of the mounting hole 28. The slider 34 is movably installed inside the groove through the support mechanism 35. A cable 20 is movably installed inside the mounting hole 28. The support mechanism 35 is a support spring. The support spring deforms under pressure or tension. After deformation, the support mechanism 35 pushes the slider 34 and the limiting ring 33 to move back to their original positions. Thus, the limiting ring 33 drives the cable 20 to retract into the fixed tube 27 for shielding and protection while also allowing for cable management.

[0024] In this embodiment, a fixing plate 44 is fixed to one end of the limiting post 45. A reset mechanism 43 is fixedly installed between the fixing plate 44 and the fixing ring 42. A protruding ring 46 is welded to the inner wall of the support tube 40, and the protruding ring 46 cooperates with the fixing ring 42. A clamping plate 37 is movably installed inside the movable box 4. The clamping plate 37 is fixedly installed at one end of the limiting post 45. A groove 38 is opened inside the clamping plate 37, and a prediction terminal 39 is movably installed inside the groove 38. A protrusion is fixed on the inner wall of the limiting seat 7, and a cleaning brush plate is fixed on the inner wall of the protrusion. The protrusion is movably installed inside the mounting cavity through the cleaning brush plate. The reset mechanism 43 is a reset spring. The reset spring deforms when compressed. In use, when one end of the extrusion column 41 moves out of the slot 5 or the fixing slot 24, one end of the extrusion column 41 loses the limiting force, and the limiting column 45 presses against the reset mechanism 43. The reset mechanism 43 compresses and contracts to provide movement space for the limiting column 45. After the 45 moves, the clamping plate 37 moves to the side to disassemble the prediction terminal 39. When the extrusion column 41 is installed inside the slot 5 or the fixing slot 24, the extrusion column 41 moves towards the fixing plate 44 and extrudes the reset mechanism 43. After the reset mechanism 43 is extruded, it retracts to the maximum extent. The limit column 45 cannot push the reset mechanism 43 and the extrusion column 41 to move, and the clamping plate 37 cannot move either. Thus, the spring force generated by the reset mechanism 43 enables the clamping plate 37 to complete the clamping and installation of the prediction terminal 39. The predictive terminal 39 internally includes an AC sampling unit, a combined current transformer module, a loop inspection unit, a main control storage unit, a communication module, an AC power supply, a backup power supply, a power management module, and external interfaces. Based on the integrated distribution terminal, it features optimized design of the AC sampling circuit, backup power supply and power management circuit, expansion modules, operating system kernel layer, and system service layer. The external interfaces include a serial interface, Bluetooth module, and Ethernet module, used to establish communication connections with various operating devices and the master station for data exchange, including acquiring operating data, receiving control commands, and issuing control commands. The intelligent terminal possesses high-speed continuous sampling capability for distribution area voltage and current, meeting the requirements for steady-state and transient data detection of power quality, while maintaining the original metering function and accuracy of the integrated terminal. The signal conditioning circuit, sampling chip selection, sampling circuit topology, and sampling auxiliary circuit have been optimized. After predicting future user energy consumption through load forecasting algorithms and issuing control commands to operating equipment, the optimal control method is provided through model predictive control algorithms. Model predictive control algorithms include: establishing an internal model, determining a reference trajectory, designing the control algorithm, and implementing online optimization. The three key components are the predictive model, rolling optimization, and feedback correction. The predictive model is used to run the algorithm for output over a future period; rolling optimization is used for continuous online optimization in the finite-time domain; and feedback correction is used to correct the predictive model by feeding back prediction errors, thereby improving prediction accuracy. Rolling optimization and feedback correction compensate for the shortcomings of low model accuracy and suppress disturbances.

[0025] Working principle: During use, the installation position and angle of the mounting plate 17 are adjusted according to the installation space. When the fixed box 1 needs to be suspended inside the control cabinet, the tilt angle of the support base on the fixed base 11 is adjusted according to the width of the internal space of the control cabinet. After the support base is distributed in a V shape, the mounting plate 17 rotates on the support base through the connecting seat 16. After the mounting plate 17 rotates, the installation point is adjusted. It is fixed by the through holes and bolts on the mounting plate 17 and the limiting plate 18. In addition, when the equipment needs to be fixed on the ground, the limiting plate 18 is rotated into the bottom of the fixed box 1. The fixed box 1 is fixed by the limiting plate 18. Under the suspension installation, the movable box 4 is moved inside the fixed box 1 by pushing it up and down. When the upper part is empty... When the movable box 4 moves upward, the bottom of the movable box 4 is pushed to move it upward. After the movable box 4 moves upward, the fixing plate 9 drives the fixing frame 10 to tilt and move. The tilting movement of the fixing frame 10 drives the positioning column 12 to move inside the positioning tube 13. The positioning column 12 retracts and moves inside the positioning tube 13 to provide support for the up and down movement of the movable box 4. When the movable box 4 moves upward, the limiting component 21 is exposed from the bottom inside the slot 5. The bottom support component 22 moves to one end of the fixing slot 24 and limits the movable box 4. Under the limitation of the support component 22, the side cover 23 loses the limiting force of the fixed box 1. The torsion spring shaft at one end of the cover 23 automatically pushes the cover 23 outward. When opened, the cover 23 is made of transparent material. After the cover 23 retracts and moves into the fixed box 1, the data displayed on the prediction terminal 39 can be observed through the observation window 2 in conjunction with the cover 23. When the movable box 4 needs to retract into the fixed box 1, the movable box 4 moves downward, and the fixed frame 10 pushes the positioning column 12 to retract into the positioning tube 13 again. When the positioning column 12 moves from a horizontal state to one end tilting downward, the tension spring inside the positioning tube 13 pushes the positioning column 12 outward. The tension spring provides assistance for the movement of the movable box 4. In addition, under the pushing force of the tension spring, the movable box 4 is always limited and installed inside the fixed box 1 for protection. During use, when the squeezing column 41... After one end of the extrusion post 41 is removed from the slot 5 or the fixed slot 24, the end of the extrusion post 41 loses its limiting force. The limiting post 45 then presses against the reset mechanism 43. The reset mechanism 43 compresses and contracts to provide space for the limiting post 45 to move. After the limiting post 45 moves, the clamping plate 37 moves to the side to disassemble the prediction terminal 39. When the extrusion post 41 is installed inside the slot 5 or the fixed slot 24, the extrusion post 41 moves towards the fixed plate 44 and presses against the reset mechanism 43. After the reset mechanism 43 compresses and contracts to its maximum extent, the limiting post 45 can no longer push the reset mechanism 43 and the extrusion post 41 to move. As a result, the clamping plate 37 cannot move either. Thus, the rebound force generated by the reset mechanism 43 enables the clamping plate 37 to complete the clamping and installation of the prediction terminal 39.The exhaust fan inside the heat dissipation component 6 at the top of the movable box 4 drives airflow to cool the predictive terminal 39 inside the movable box 4. An exhaust vent is located at the bottom of the movable box 4, and the exhaust fan blows air downwards for cooling. The cable 20 is secured by the compression bolts 30. Before the cable 20 is secured, the top cable 20 provides a suitable length for the movable box 4 to move up and down. When the movable box 4 or other directions pull the cable 20, the cable 20 causes the limiting ring 33 to move up and down inside the fixing tube 27 for buffering and vibration reduction, thereby preventing damage to the cable 20 caused by external forces. Additionally, the fixing tube 27 achieves [further details needed]. Simultaneously, the limiting ring 33 moves up and down via the support mechanism 35 to facilitate the rapid retraction and return of the moved cable 20 to its original position, making it easy to store later. When it is necessary to limit the direction of movement of the movable box 4, the limiting seat 7 rotates and moves to the top of the fixed box 1. After the limiting seat 7 moves to the top of the fixed box 1, the movable box 4 cannot move downwards under the limitation of the limiting seat 7. In addition, the limiting seat 7 at the top of the movable box 4 not only limits the movable box 4 but also rotates on the heat dissipation component 6. The cleaning brush on the inner wall of the limiting seat 7 scrapes and cleans the surface of the heat dissipation component 6, facilitating the scraping and cleaning of dust.
