[0002] Energy storage technology plays an increasingly important role in balancing energy supply and demand and improving the flexibility of power systems. Traditional power systems usually rely on basic sources such as thermal power and hydropower for power generation, while renewable energy often faces challenges in power dispatch due to its unstable power generation. Therefore, energy storage power stations have gradually become an important means to improve the efficiency of renewable energy utilization. At present, in the power system, the application scenarios of energy storage power stations can be divided into power generation side energy storage, grid side energy storage and power consumption side energy storage, and different energy storage application scenarios play different roles.

In the energy storage power station on the distribution side of the power grid, battery energy storage equipment, battery management equipment, grid-connected power distribution equipment, etc. are usually installed. When the power station is working, the temperature of the multiple battery components inside is high. Once a fire occurs in the battery energy storage equipment, it often spreads quickly, releasing a large amount of heat and toxic smoke, posing a huge threat to surrounding equipment and facilities and personal safety. Since the multiple battery groups are not separated and protected inside the energy storage power station, when one battery catches fire, it is easy to cause other battery groups to catch fire. At the same time, in terms of power supply and grid connection, the traditional power grid architecture often has technical barriers to the access of energy storage power stations, such as the compatibility of grid-connected equipment and the mismatch of scheduling algorithms.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The energy storage power station of the present invention is used on the distribution side of the power grid, and adopts a partition structure to improve fire safety. The battery cavity of the energy storage power station is divided by a partition plate, so that the battery pack can be installed in each independent cavity, so that when a fire occurs in a single battery pack, it can be separated in time to prevent the spread of fire. In addition, under normal circumstances, the partition plate does not completely isolate the battery cavity, but leaves heat dissipation grooves on the upper and lower sides so that the energy storage power station can better control the temperature. An installation groove is left in the middle of the partition plate, and the base and the adapter plate are arranged through the installation groove, and the adapter socket is installed on the adapter plate. When separated by the partition plate, the battery packs on both sides are connected by connecting the plug and the adapter socket at the same time to ensure the formation of a complete storage and discharge unit. In the event of a fire, the heat dissipation grooves on the upper and lower sides of the partition plate are blocked by the lifting plate, and the installation groove can be blocked by a fire curtain to effectively isolate the flame.

[0026] 2. The adapter sockets of the present invention all adopt a shallow slot structure to ensure that the plug can be separated from the socket in time when a fire occurs, and a clamping piece is arranged on the base. Under normal circumstances, the stable connection of the plug can be ensured by the two clamping pieces. When a fire occurs, as the fire curtain closes, the clamping piece can be driven to retract, so that the plug can be easily detached from the adapter plug. At the same time, the docking block pulls the fire curtain to isolate the flame when moving along the base, and the push wheel thereon rotates, and an outward thrust is generated when it contacts the plug, so that the plug is detached from the adapter socket, and the battery packs in different cavities or the electrical equipment of the energy storage power station are disconnected in time, ensuring that the fire curtain can cover the installation slot and prevent the spread of flames.

[0027] 3. The fire curtain and the lifting plate are driven by the first piston rod and the second piston rod respectively. The first piston rod and the second piston rod move automatically when the expansion gas box is at a high temperature, so that the fire curtain is automatically opened and the lifting plate is automatically raised when a fire occurs, so that the partition plate becomes a completely closed state to isolate the flame. When the lifting plate located on the top of the partition plate rises, the fire extinguishing agent in the liquid storage box can also flow out and flow down along the partition plate, slowing down the spread of the fire and buying time for emergency repair work.

[0028] 4. The power supply and grid-connected method of the present invention can overcome the technical obstacles in traditional grid-connected methods and ensure the safe, stable and efficient grid-connected operation of the energy storage power station and the power grid; through system initialization, synchronization operation before grid connection and configuration of grid-connected protection devices, the stable operation of the equipment when the energy storage power station is grid-connected is guaranteed; through the power quality management module, the power parameters are monitored and optimized, thereby improving the overall power quality; the active and reactive power outputs are dynamically adjusted according to the power grid demand, efficient power support is provided, grid load fluctuations are met, and the response capability of the energy storage power station is enhanced; through the configuration of the grid-connected protection equipment, the safe operation of the system under abnormal conditions is ensured; through the grid-connected test, it is ensured that the energy storage power station has good grid-connected performance, can adapt to changes in the power grid load and pass the test of extreme conditions such as short-circuit tests.

[0043] See also Figures 1 to 12 The present invention provides a technical solution: a partitioned energy storage power station, including a power station body 1, a battery cavity 2 for installing energy storage equipment and power distribution equipment is arranged in the power station body 1, and the battery cavity 2 is divided into independent installation cavities by a partition plate 3, a mounting groove 4 is arranged on the partition plate 3, and a base 5 is arranged in the mounting groove 4, an adapter plate 6 with an adapter socket 7 is installed on the base 5, the equipment on both sides of the partition plate 3 is connected through the adapter socket 7, a movable clamping member 9 is installed on the base 5, and the plug on the adapter socket 7 is fixed to the anti-dropping fixation by the clamping member 9, a bottom plate 13 is symmetrically arranged on both sides of the mounting groove 4, and a telescopic fire curtain 14 is fixedly connected to the bottom plate 13, and a docking block 15 is arranged at the end of the fire curtain 14, a groove 16 is arranged on the docking block 15, and a rotating member that rotates with the movement of the docking block 15 is installed in the groove 16 The push wheel 17 is moved, and when the docking block 15 moves to the position of the adapter socket 7, the clamping piece 9 can be loosened, and the plug can be pulled out by the push wheel 17. An expansion gas box 21 is fixedly installed on the partition plate 3, and hot expansion gas is arranged in the expansion gas box 21. The two ends of the expansion gas box 21 are respectively provided with a first piston rod 22 and a second piston rod 23, and the first piston rod 22 is connected to the docking block 15 through a bracket 24, and a card key 25 that can be engaged with each other is arranged on the bracket 24. A heat dissipation groove is left between the partition plate 3 and the upper and lower surfaces of the power station body 1, and a lifting plate 27 is slidingly installed at the upper and lower ends of the partition plate 3, and the lifting plate 27 is connected to the second piston rod 23. A liquid storage box 29 is arranged on the top of the power station body 1, and the liquid storage box 29 is filled with fire extinguishing agent. When the lifting plate 27 contacts the bottom surface of the liquid storage box 29, it can cause it to rupture.

[0044] like Figure 1 , Figure 2 As shown, the partition plate 3 is tightly connected to the front and rear inner surfaces of the battery cavity 2 through fixings, and a gap is left between the partition plate 3 and the upper and lower inner surfaces of the battery cavity 2 as a heat dissipation groove, and the lifting plate 27 is located in the heat dissipation groove, and the lifting plate 27 is installed in the limit groove 26 of the partition plate 3.

[0045] The energy storage power station of the present invention is used on the distribution side of the power grid, and can release the stored electrical energy when needed. A battery cavity 2 is set in the power station body 1 of the energy storage power station, and energy storage equipment such as batteries are installed through the battery cavity 2. In addition to installing multiple groups of batteries in the battery cavity 2, distribution equipment such as transformers, switchgear, monitoring and protection equipment, etc. can also be installed by opening other battery cavities 2. The key point is that the batteries in the battery cavity 2 are separated by the partition plate 3 so that the equipment can be installed in each independent cavity, so that when a fire occurs in a single device, it can be separated in time to prevent the spread of fire and improve the safety of the equipment.

[0046] like Figure 3-Figure 6 As shown, two mounting grooves 4 are arranged on the partition plate 3, and the mounting grooves 4 are through grooves, the base 5 is located in the middle of the mounting groove 4, and the fire curtain 14 is arranged at the upper and lower ends of the mounting groove 4, the adapter socket 7 is arranged on the adapter plate 6, and the adapter socket 7 is divided into a power socket and a signal socket.

[0047] Under normal circumstances, the partition plate 3 does not completely isolate the battery cavity 2, but leaves heat dissipation grooves on the upper and lower sides so that the energy storage power station can better control the temperature. A mounting groove 4 is left in the middle of the partition plate 3, and the base 5 and the adapter plate 6 are arranged through the mounting groove 4, and the adapter socket 7 is installed on the adapter plate 6. When separated by the partition plate 3, the devices on both sides are connected by connecting them with the adapter socket 7 at the same time with plugs. In the event of a fire, the heat dissipation grooves on the upper and lower sides of the partition plate 3 are blocked by the lifting plate 27, and the mounting groove 4 can be blocked by the fire curtain 14 to effectively isolate the flame.

[0048] like Figure 7 As shown, a slide bar 8 is horizontally slidably mounted on the base 5, and the front end of the slide bar 8 is located on the end surface of the adapter socket 7, and the rear end of the slide bar 8 extends into the base 5. A clamping member 9 is mounted on the front end of the slide bar 8, and a spring 10 is connected between the clamping member 9 and the base 5, and the clamping member 9 is symmetrically arranged on the base 5. An oblique push groove 11 is arranged at the rear end of the slide bar 8, and a pressing member 12 is movably mounted on the base 5, the pressing member 12 is inserted into the oblique push groove 11, and the pressing member 12 is arranged to protrude from the surface of the base 5, and when the docking block 15 moves, the pressing member 12 can be pressed inward to push the slide bar 8.

[0049] To ensure that the plug can be separated from the socket in time when a fire occurs, the adapter socket 7 of the present invention adopts a shallow slot structure, and a clamping piece 9 is provided on the base 5. Under normal circumstances, the elastic force of the spring 10 acts on the clamping piece 9, which can act on both sides of the plug through the two clamping pieces 9 to ensure the stable connection of the plug. When a fire occurs, as the fire curtain 14 closes, the docking block 15 thereon can move along the surface of the base 5, pressing the protruding pressing piece 12 inwardly, and the pressing piece 12 pulls the slide rod 8 along the inclined push groove 11, so that the slide rod 8 drives the clamping piece 9 to retract. At this time, the plug is easy to detach from the adapter plug to avoid affecting the closing of the fire curtain 14.

[0050] like Figure 8-Figure 11 As shown, the two symmetrically arranged docking blocks 15 can be closed when connected, and the turning wheel 17 is installed in the groove 16 through the rotating shaft 18, a cavity is provided in the docking block 15, and a steering wheel 19 coaxially connected to the turning wheel 17 is provided in the cavity, and a friction wheel 20 is convexly rotatably installed on the docking block 15, and the friction wheel 20 is connected to the steering wheel 19, and the friction wheel 20 is in contact with the surface of the base 5.

[0051] When a fire occurs, a thrust is applied to the docking block 15 through the first piston rod 22, so that the docking block 15 moves along the base 5. Usually, the fire curtains 14 are symmetrically arranged on both sides of the installation groove 4. As the two docking blocks 15 approach, the two fire curtains 14 can gradually close the installation groove 4, and the fire curtains 14 are used to isolate the flame. In the process of the movement of the docking block 15, when it moves to the position of the adapter socket 7, on the one hand, the clamping member 9 is retracted by compressing the pressing piece 12 to release the plug. On the other hand, when the friction wheel 20 on the docking block 15 moves therewith, it is rotated by the friction force of the base 5. The friction wheel 20 can drive the steering wheel 19, thereby causing the turning wheel 17 to rotate therewith. When the turning wheel 17 contacts the plug, an outward thrust is generated, which can cause the plug to detach from the adapter socket 7, and the equipment in different cavities can be disconnected in time. At the same time, after the plug is detached, the fire curtain 14 can cover the installation groove 4 to prevent the flame from spreading.

[0052] like Fig. 9 As shown, the expansion gas box 21 is vertically arranged, and when the expansion gas box 21 is in a high temperature environment, the first piston rod 22 and the second piston rod 23 can move in the vertical direction, and the fire curtain 14 and the lifting plate 27 are moved in the opposite direction through the first piston rod 22 and the second piston rod 23.

[0053] The fire curtain 14 and the lifting plate 27 are driven by the first piston rod 22 and the second piston rod 23 respectively, and both can move automatically when a fire occurs. When the fire causes high temperature, the hot expansion gas in the expansion gas box 21 expands due to the heat, pushing the first piston rod 22 and the second piston rod 23 outward at the same time, thereby achieving the effect of pulling open the fire curtain 14 and raising the lifting plate 27, so that the partition plate 3 becomes a completely closed state to isolate the flame.

[0054] like Fig.12 As shown, the lifting plate 27 is installed at the end of the second piston rod 23, and the surface of the lifting plate 27 is arranged with piercing pieces 28. The liquid storage box 29 is embedded in the top surface of the power station body 1, and the bottom surface of the liquid storage box 29 is closed by the lower support plate 30. The piercing piece 28 is a conical structure, and the piercing piece 28 can pierce the lower support plate 30 to achieve the effect of the fire extinguishing agent flowing down.

[0055] When the lifting plate 27 located on the top of the partition plate 3 is raised, the tie piece 28 thereon can also contact the lower support plate 30 of the liquid storage box 29, forming a hole on the lower support plate 30, so that the fire extinguishing agent inside it flows out and flows down along the partition plate 3, slowing down the spread of the fire and buying time for emergency repair work.

[0057] Step 1: System initialization, confirming that all equipment in the energy storage power station is operating normally, including energy storage equipment and power distribution equipment, and checking the voltage, current and other parameters of the grid connection point to ensure that they meet the grid connection requirements;
