Description

Technical Field

[0001] The present invention relates to the technical field of broadband oscillation suppression, and specifically to a broadband oscillation suppression device and a suppression method for a new energy power generation station. Background Art

[0002] Broadband oscillation refers to the phenomenon that the oscillation frequency in the power system presents a broadband characteristic. In the new power system, due to the high proportion of new energy and the large-scale application of power electronic equipment, the problem of broadband oscillation becomes particularly important. This problem not only affects the power quality and equipment safety of the power grid, but also induces system stability problems, seriously affecting the level of new energy consumption.

[0003] Broadband oscillations can be suppressed by designing a suitable control system. A common method is to design a controller with suitable control parameters, such as a PID controller. The PID controller can adjust the control signal according to the real-time status of the system to suppress broadband oscillations. Another method is to use a filter to limit the frequency response range of the system to reduce the impact of broadband oscillations. A suitable filter can be designed to filter out the frequency components that cause broadband oscillations in the system to make the system more stable. In general, suppressing broadband oscillations requires comprehensive consideration of the system's characteristics and control methods, and designing a suitable control system or filter to achieve stable system operation.

[0004] Existing filters are placed in open-air locations, and the terminals and wires are fixed together by nuts. However, no protective measures are taken for the terminals and wires. In sandstorm weather, a large amount of sand and dust are easily accumulated on the surface of the terminals and wires. When the wires are working, the sand cannot be removed. The most common component of sand is silicon dioxide SiO2. When too much sand accumulates, it is easy to produce a certain degree of insulation, which makes its conductivity worse, the current unstable, and the filter cannot work normally.

[0019] The present invention provides a wide-band oscillation suppression device for a new energy power generation station and a suppression method thereof. Compared with the prior art, it has the following beneficial effects:

[0020] 1. A new energy power station wide-band oscillation suppression equipment and a suppression method thereof are used in combination with a driving part and a protective part.

[0021] 2.

[0023] 4. A wide-band oscillation suppression equipment and a suppression method for a new energy power station are used in combination with a lifting member and a pneumatic clamp.

[0036] In this embodiment, a driving member is provided to transport gas to a position where work is required, and the gas stored inside the gas storage box a8 and the gas storage box b15 can be an inert gas, and the protective member can be driven by the gas so that it can be sleeved on the outer wall of the terminal 4, thereby forming protection, and the protective member can be an insulating member.

[0037] Specifically, the limiting component includes a movable chamber 111, a piston a121, a connecting tube 122, a plug-in tube 123, and a side limiting box 124. The movable chamber 111 is located inside the sleeve 11. The outer wall of the piston a121 and the interior of the movable chamber 111 are mutually socketed. The bottom of the piston a121 and the top of the telescopic sleeve 12 are fixedly connected. The connecting tube 122 is embedded in the interior of the piston a121. The bottom of the connecting tube 122 is fixedly connected to the side limiting box 124, and the side of the side limiting box 124 is fixedly connected to the plug-in tube 123.

[0038] In this embodiment, when the protective member is sleeved on the outer wall of the terminal 4, the limiting member will extend into the interior of the terminal 4 to form a limit, so that the protective member exerts a downward pressure on the wire, so that it is tightly fixed at the position where it needs to work.

[0039] Specifically, a flow cavity 1241 is provided inside the side limit box 124 . The flow cavity 1241 and the interior of the connecting pipe 122 are connected to each other. A clamping piece is provided at the bottom of one side of the flow cavity 1241 .

[0040] In this embodiment, the clamping part can be extended by injecting gas into the flow cavity 1241. When the gas is extracted, the clamping part will be retracted, shortening the length of the clamping part so that it can be quickly detached from the clamping part, which is convenient for canceling the limit and quickly recovering it.

[0041] Specifically, the clamping part includes a movable cylinder 1242, a cavity c1243, a piston c1244, a connecting rod 1245, a spring 1246, and a clamping joint 1247. The outer wall of the movable cylinder 1242 is fixedly connected to the outer wall of the side limit box 124, the movable cylinder 1242 is internally movably sleeved with the connecting rod 1245, a cavity c1243 is provided inside the movable cylinder 1242, the interior of the cavity c1243 is internally movably sleeved with the piston c1244, the outer wall of the piston c1244 is fixedly connected to the connecting rod 1245, one side of the connecting rod 1245 is fixedly connected to the clamping joint 1247, the outer wall of the clamping joint 1247 is fitted and connected to the spring 1246, and the outer wall of the spring 1246 and the outer wall of the connecting rod 1245 are sleeved with each other.

[0042] In this embodiment, when the air inside the flow chamber 1241 is extracted, the spring 1246 can pull the piston c1244 and the clamping joint 1247 back to their original positions through the rebound force, and the clamping joint 1247 and the connecting rod 1245 are insulating components to prevent the spring 1246 from being heated and deformed during conduction.

[0043] Specifically, a circular hole 401 is formed inside the terminal 4 , a rectangular groove 402 is formed on one side of the circular hole 401 , a fixing opening 403 is formed at the bottom of one side of the rectangular groove 402 , and the inside of the fixing opening 403 and the outer wall of the clamping joint 1247 are adapted to each other.

[0044] In this embodiment, the round hole 401 is provided to allow the plug-in tube 123 to extend therein, while the side limit box 124 and the clamping member extend thereinto to form a limit, so that the wire can be tightly fixed to the outer wall of the terminal 4 to avoid falling off during operation.

[0045] Specifically, a lifting component is fixedly connected to the surface of the fan 5; the lifting component includes a delivery pipe b14, an air storage box b15, an air cylinder 16, a lifting rod 17, and a placement panel 18. The outer wall of the fan 5 is fixedly connected to the delivery pipe b14, the outer wall of the delivery pipe b14 is fixedly connected to the air storage box b15, the top of the air storage box b15 is fixedly connected to the air cylinder 16, the interior of the air cylinder 16 is movably sleeved with the lifting rod 17, the top of the lifting rod 17 is fixedly connected to the placement panel 18, a cavity a161 is opened inside the air cylinder 16, the interior of the cavity a161 is movably sleeved with a limiting ring 162, the top of the limiting ring 162 is fixedly connected to the lifting rod 17, and a storage cavity is opened inside the lifting rod 17.

[0046] In this embodiment, the lifting member is used to allow gas to accumulate inside the storage chamber during operation, and the gas is allowed to enter the lifting rod 17 for accumulation. As the density increases, the lifting rod 17 will be lifted up so that the wire can be lifted up. When the gas is extracted from the inside of the lifting member, the gas density becomes smaller and the lifting member will slowly shrink, which can achieve the removal and installation of the wire and enhance safety.

[0047] Specifically, a pneumatic clamp is provided at the top of the lifting rod 17; the pneumatic clamp includes a side tube 163, a rectangular sleeve 164, a clamping block 165, and a roller 166. Both sides of the lifting rod 17 are fixedly connected to the side tube 163, the top of the side tube 163 is fixedly installed with a rectangular sleeve 164, the inside of the rectangular sleeve 164 is movably sleeved with the clamping block 165, and the inside of the clamping block 165 is movably installed with a roller 166.

[0048] In this embodiment, by providing a pneumatic clamp, the wire can be quickly clamped at the spacing through the roller 166, thereby playing a role of lateral limiting to prevent it from coming off during the operation.

[0049] Specifically, a pneumatic part is arranged inside the side tube 163, and the pneumatic part includes a cavity b1631, a movable rod 1632, a limiting ring 1634, and a piston b1633. The cavity b1631 is opened inside the side tube 163, and the interior of the cavity b1631 is connected to the interior of the lifting rod 17. The interior of the cavity b1631 is movably connected to the piston b1633, and the outer wall of the piston b1633 is fixedly connected to the outer wall of the movable rod 1632. The outer wall of the movable rod 1632 is movably connected to the interior of the limiting ring 1634. The outer wall of the limiting ring 1634 is fixedly connected to the interior of the cavity b1631, and the outer wall of the limiting ring 1634 is fixedly connected to the back of the clamping block 165.

[0050] In this embodiment, when gas is stored inside the cavity b1631, the movable rod 1632 will be pushed out to allow the clamping block 165 fixedly connected to the outer wall to form a clamping force on the wire, thereby avoiding the problem of slipping during the lifting and disassembly process.

[0051] Specifically, the interior of the choke tube 6 includes a movable groove 603, an axle rod 601, a circular plate 602, and a torsion spring 6023. The movable groove 603 is opened inside one side of the choke tube 6, and the axle rod 601 is movably installed inside the movable groove 603. The outer wall of the axle rod 601 is fixedly connected to the circular plate 602, and both ends of the axle rod 601 are movably sleeved with the torsion spring 6023.

[0052] In this embodiment, by setting a torsion spring 6023, the fan 5 can make the circular plate 602 flip toward the side of the exhaust during the exhaust process. The torsion spring 6023 will be deformed during the flipping. When the fan 5 stops working, the torsion spring 6023 will reset to restore the circular plate 602 to its original state. When the fan 5 is not working, the gas stored in the circular plate 602 cannot push the circular plate 602 to flip to one side. At this time, the gas backflow can be avoided, so that it can work normally.

[0053] Working principle:

[0054] In the preparation step, the wire is placed on the surface of the placement panel 18. During the placement process, the wire will rub against the roller 166, causing the wire to move quickly to the surface of the placement panel 18. Because the roller 166 is installed laterally and movably, this will form a lateral limiting force on the wire, fixing it on the surface of the placement panel 18.

[0055] Working steps, at this time, the fan 5 is started, and the air stored in the gas box b15 is extracted by the fan 5. During the extraction process, the gas density inside the gas cylinder 16 becomes smaller, so that the lifting rod 17 that is movably sleeved inside the gas cylinder 16 will slowly move down. During the lowering process, the wire fixed on the surface of the placement panel 18 will be sleeved with the outer wall of the terminal 4. During the sleeve process, the wire will move longitudinally from the surface of the placement panel 18. When the gas is extracted from the inside of the gas box b15, it will be directly discharged into the inside of the gas box a8 through the fan 5. The gas box a8 can be used to transport the gas into the internal storage of the sleeve 11, which causes the gas in the active chamber 1 When the internal storage of 11 is in progress, the density will increase, so that the piston a121 is pushed downward, and during the pushing process, the telescopic sleeve 12 will extend from the inside of the sleeve 11. Therefore, when the wire is sleeved on the outer wall of the terminal 4, the inside of the telescopic sleeve 12 will cover the outer wall of the terminal 4. At the same time, the plug-in tube 123 will extend into the inside of the circular hole 401, and the side limit box 124 fixedly connected on one side will be clamped in the inside of the rectangular groove 402. During the clamping process, the clamping joint 1247 will extend into the inside of the fixed port 403, thereby forming a limit, so that the telescopic sleeve 12 will form a limit on the bottom wire to avoid falling off during work.

[0056] At the end of the step, when it is necessary to disassemble and repair the wires, just start the fan 5 in reverse. When starting, the gas stored in the gas storage box a8 will be transported into the gas storage box b15 through the choke tube 6. During the transportation process, the gas in the active chamber 111 can be transported into the delivery pipe a9. At this time, the gas stored in the side limit box 124 will be discharged through the connecting pipe 122. When discharged, a suction force will be formed in the flow chamber 1241, causing the connecting rod 1245 to be pulled toward the inside of the movable cylinder 1242 by the piston c1244. When pulling, not only the spring 1246 will be squeezed, but also the clamping joint 1247 will be out of contact with the fixed port 403, so that the limit is cancelled, allowing the telescopic sleeve 12 to be retracted into the inside of the sleeve 11. When the heat dissipation fins 13 and the bottom of the sleeve 11 are in contact with each other, the telescopic sleeve 12 will be retracted. The above-mentioned heat dissipation fins 13 can not only act as limit At the same time, it can also increase the heat dissipation area and assist the above-mentioned mechanism to dissipate heat. When the gas is continuously accumulated inside the gas storage box b15, the gas density inside the gas cylinder 16 becomes larger, so that the lifting rod 17 will be lifted up by the gas, and during the lifting process, it will slowly extend out from the inside of the gas cylinder 16. When the gas accumulates inside the lifting rod 17, it will directly enter the inside of the side tube 163. As the gas is stored in the cavity b1631, the piston b1633 can be slowly pushed out from the inside of the cavity b1631. During the pushing process, the clamping block 165 will be pushed out by the movable rod 1632. When the lifting rod 17 extends out of the inside of the gas cylinder 16, the wire will be lifted up, and when it is lifted up, the wire will be clamped by the clamping block 165. The roller 166 and the clamping block 165 can cooperate to fix it tightly on the surface of the placement panel 18, so that it can be separated from the outer wall of the terminal 4, thereby facilitating disassembly and maintenance.
