Description

Technical Field

[0001] This utility model relates to the field of VSG controller technology, and in particular to a VSG controller. Background Technology

[0002] Against the backdrop of the current power system's transition to a high proportion of renewable energy, VSG (Virtual Synchronous Generator) control technology has received widespread attention as a key means to improve system stability and reliability. The VSG controller can simulate the rotational inertia and damping characteristics of a traditional synchronous generator, providing frequency and inertial support for microgrid systems. This is achieved through active-frequency regulation loops and reactive-voltage control loops, simulating the frequency and voltage regulation processes of a synchronous generator, respectively. By introducing an adaptive rotational inertia control strategy, the VSG controller can adjust the magnitude of the rotational inertia in real time according to the system state, thereby effectively reducing system frequency fluctuations, improving system frequency characteristics, and enhancing overall stability. The cost function in the VSG controller is flexible and can be designed to achieve different control effects according to different needs. This allows the VSG controller to adapt to various operating conditions and control objectives, improving control flexibility and adaptability.

[0003] The VSG controller is equipped with a data cable connector for connecting other devices. When the VSG controller is not in use and the data cable connector is not connected, dust in the air can easily enter the connector. If a lot of dust adheres to the inside of the connector, it will affect the normal connection with the data cable. In addition, the heat generated inside the VSG controller is dissipated slowly during use, and the heat dissipation effect of the heat dissipation vents on the device casing is limited and cannot achieve effective heat dissipation of the device. Therefore, this application proposes a VSG controller. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a VSG controller to solve the problems in the background art where the data cable connector on the VSG controller is prone to dust ingress when not in use, and the heat dissipation vents on the outer casing alone cannot effectively dissipate heat from the device.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A VSG controller includes a main body, a recessed area extending from front to back is provided at the bottom of the main body, an opening communicating with the interior of the main body is provided at the central outlet at the top of the recessed area, a cooling fan extending into the interior of the main body is installed at the opening, three connectors are fixedly installed at the rear end of the main body, and protective components are provided on each of the three connectors, a plate groove is also provided at the rear end of the main body, a heat dissipation vent communicating with the interior of the main body is provided on the inner side of the plate groove, a dustproof plate covering the heat dissipation vent is provided inside the plate groove, and a second dustproof net is provided between the dustproof plates.

[0006] Optionally, the bottom of the cooling fan is flush with the top of the recessed area, and multiple inclined air guide plates are fixedly installed on the top of the cooling fan, with the multiple air guide plates on the top of the cooling fan inclined toward the heat dissipation vent at the rear of the main body. A first dustproof net is fixedly installed on the bottom of the cooling fan.

[0007] Optionally, four first grooves are evenly provided around the bottom of the opening, and a first hanging ear is fixedly installed on the bottom of the outer wall of the cooling fan. The four first hanging ears on the cooling fan are respectively located in the corresponding first grooves, and a first bolt that is threadedly connected to the first groove is inserted through each of the four first hanging ears.

[0008] Optionally, the protective assembly includes a threaded ring and a protective sleeve. The threaded ring is threaded onto the connector, and fixing bolts are fixedly installed on both sides of the threaded ring. The protective sleeve is slidably fitted onto the end of the connector, and connecting rods are fixedly installed at both ends of the protective sleeve. The ends of the two connecting rods away from the protective sleeve are respectively rotatably fitted onto the fixing bolts on both sides of the threaded ring.

[0009] Optionally, a second groove is provided on both sides of the plate groove, and a second hanging ear located in the corresponding second groove is fixedly installed at both ends of the dustproof plate. A second bolt that is threadedly connected to the second groove is inserted through the two second hanging ears.

[0010] Optionally, rubber pads are glued to both ends of the protruding parts on both sides of the bottom of the main body, and a display screen and control components are set on the top of the main body.

[0011] The beneficial effects of this utility model are:

[0012] 1. By installing a cooling fan that communicates with the interior of the main body at the top of the recessed area, and setting multiple air guide plates on the top of the cooling fan facing the heat dissipation vent, the cooling fan can normally draw in air through the bottom recessed area and blow it into the interior of the main body. Under the action of multiple air guide plates, the air blown out by the cooling fan will blow towards the heat dissipation vent, thereby enabling the heat inside the main body to be quickly discharged through the heat dissipation vent, thus effectively dissipating heat from the main body.

[0013] 2. Each joint on the main body is equipped with a protective component, which can provide effective protection when the joint is not in use. When the joint is not in use, the threaded ring is moved to the end of the joint by turning it, and then the protective sleeve is rotated so that it is on the same horizontal axis as the threaded ring. Then the threaded ring is turned in the opposite direction, so that the threaded ring can move the protective sleeve together, so that the protective sleeve is placed on the end of the joint. In this way, the protective sleeve can protect the joint and prevent dust or water stains from entering the interior of the joint. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a VSG controller, including a main body 1. The bottom of the main body 1 has a recessed area 4 that runs through the front and back. An opening 5 communicating with the interior of the main body 1 is opened at the center outlet at the top of the recessed area 4. A cooling fan 7 extending into the interior of the main body 1 is installed at the opening 5. Three connectors 2 are fixedly installed at the rear end of the main body 1. Each of the three connectors 2 is provided with a protective component 3. The rear end of the main body 1 also has a plate groove 11. A heat dissipation port 12 communicating with the interior of the main body 1 is opened on the inner side of the plate groove 11. A dustproof plate 13 covering the heat dissipation port 12 is provided inside the plate groove 11. A second dustproof mesh is provided between the dustproof plates 13. The cooling fan 7 can improve the efficiency of heat dissipation inside the main body 1, while the protective component 3 on the connector 2 can effectively protect the connector 2 when it is not in use.

[0023] like Figure 3 and Figure 4As shown, the bottom of the cooling fan 7 is flush with the top of the recessed area 4. Multiple inclined air guide plates 10 are fixedly installed on the top of the cooling fan 7, and the multiple air guide plates 10 on the top of the cooling fan 7 are all inclined toward the heat dissipation port 12 at the rear end of the main body 1. A first dustproof net is fixedly installed on the bottom of the cooling fan 7. The cooling fan 7 normally draws in air through the recessed area 4 and delivers it into the interior of the main body 1. Under the action of the multiple air guide plates 10 on the top of the cooling fan 7, the air flows along the inclination of the air guide plates 10 toward the heat dissipation port 12 at the rear end of the main body 1, thereby driving the heat inside the main body 1 to flow toward the heat dissipation port 12 and be discharged, thereby improving the efficiency of heat dissipation inside the main body 1.

[0024] like Figure 3 and Figure 4 As shown, four first grooves 6 are evenly distributed around the bottom of the opening 5. A first lug 8 is fixedly installed on the bottom of the outer wall of the cooling fan 7, and the four first lugs 8 on the cooling fan 7 are respectively located in the corresponding first grooves 6. A first bolt 9 that is threadedly connected to the first groove 6 is inserted through each of the four first lugs 8. The cooling fan 7 can be fixedly installed in the opening 5 in the recessed area 4 by the first bolt 9, so that the cooling fan 7 can normally deliver air to the inside of the main body 1. The cooling fan 7 can be disassembled for dust cleaning by unscrewing the first bolt 9.

[0025] like Figure 2 and Figure 5 As shown, the protective component 3 includes a threaded ring 31 and a protective sleeve 33. The threaded ring 31 is threaded onto the connector 2. Fixing bolts 32 are fixedly installed on both sides of the threaded ring 31. The protective sleeve 33 is slidably fitted onto the end of the connector 2. Connecting rods 34 are fixedly installed on both ends of the protective sleeve 33. The ends of the two connecting rods 34 away from the protective sleeve 33 are respectively rotatably fitted onto the fixing bolts 32 on both sides of the threaded ring 31. By twisting the threaded ring 31, it is moved to the end of the connector 2. Then, the protective sleeve 33 is rotated so that the connecting rods 34 on both sides rotate about the fixing bolts 32 on both sides of the outer wall of the threaded ring 31. When the protective sleeve 33 is rotated to be on the same horizontal axis as the threaded ring 31, the threaded ring 31 is twisted in the opposite direction. In this way, the threaded ring 31 can drive the protective sleeve 33 to move together, so that the protective sleeve 33 is fitted onto the end of the connector 2. Thus, the protective sleeve 33 can protect the connector 2.

[0026] like Figure 2 and Figure 3As shown, a second groove is provided on both sides of the plate groove 11. The two ends of the dustproof plate 13 are fixedly installed with second hanging ears 14 located in the corresponding second grooves. A second bolt 15 threadedly connected to the second groove is inserted through each of the two second hanging ears 14. The second hanging ears 14 at both ends of the dustproof plate 13 can be fixed in the second grooves on both sides of the plate groove 11 by the second bolt 15. In this way, the dustproof plate 13 can play a role in preventing dust from the heat dissipation vent 12 at the plate groove 11. And the dustproof plate 13 can be removed by unscrewing the second bolt 15, so that the second dustproof mesh on the dustproof plate 13 can be cleaned.

[0027] like Figure 1 and Figure 3 As shown, rubber pads 16 are glued to both ends of the protruding parts on both sides of the bottom of the main body 1. The rubber pads 16 can play a non-slip role on the bottom of the main body 1. A display screen and control components are provided on the top of the main body 1.
