Description

Technical Field

[0001] This invention relates to the field of power quality monitoring technology, specifically to a power quality monitoring system and method for smart distributed energy stations. Background Technology

[0002] The concept of power quality in modern power systems is becoming increasingly rich and complex. Traditional power quality monitoring systems are usually isolated, and power quality monitoring is limited to a single point. The main function of the system's information integration service is to send information from various locations to the main server through the communication network and integrate it into a unified database.

[0003] Existing quality monitoring methods for distributed energy power plants involve using multiple monitoring instruments to monitor each power plant before aggregating the data. This approach results in slow data update efficiency. Furthermore, the following issues remain in the process of addressing this technical problem:

[0004] During radar reception, the best reception effect is achieved when the radar and the signal source are directly facing each other, but the current adjustment operation of the radar is often not precise enough.

[0005] Therefore, the present invention provides a power quality monitoring system and method for intelligent distributed energy stations. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a power quality monitoring system and method for smart distributed energy stations. It solves the problem that, during radar reception, the best reception effect is achieved when the radar and the signal source are directly facing each other, but current radar adjustment operations are often not precise enough.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a power quality monitoring system for a smart distributed energy station, comprising a monitoring instrument body, a control box mounted on top of the monitoring instrument body, and a control panel mounted on the surface of the control box. Inside the control box, a receiving adjustment mechanism enables the radar receiver to rotate. This receiving adjustment mechanism allows for simultaneous horizontal and vertical rotation adjustment of the radar receiver. The receiving adjustment mechanism includes a drive motor mounted at the bottom of the control box. One end of the output shaft of the drive motor is fixedly connected to a drive shaft via a coupling. The surface of the drive shaft, through a transmission assembly, causes a secondary drive shaft to rotate on a support plate inside the control box. The top of the secondary drive shaft, through a meshing assembly, causes a transmission shaft to rotate. Inside the transmission shaft, a pneumatic assembly enables the transmission gear to rotate and move. Inside the control box, a sliding assembly allows a support shaft to move vertically. The top of the support shaft is connected to the bottom of the radar receiver via a rotating assembly. A transmission rack is mounted on the surface of the support shaft, and a horizontal rotation unit is provided on the surface of the drive shaft.

[0008] Preferably, the transmission assembly includes a drive wheel fixedly mounted on the surface of the drive shaft and an auxiliary drive wheel fixedly mounted on the auxiliary drive shaft, and the surfaces of the drive wheel and the auxiliary drive wheel are connected by a transmission belt.

[0009] Preferably, the meshing assembly includes a first bevel gear fixedly mounted on the surface of the auxiliary drive shaft, and a second bevel gear fixedly connected to the surface of the drive shaft, wherein the surfaces of the first bevel gear and the second bevel gear mesh with each other.

[0010] Preferably, the pneumatic assembly includes a cylinder installed inside the control box, the cylinder being connected to an external air circuit, a connecting rod being rotatably mounted on the output end of the cylinder, one end of the connecting rod passing through the drive shaft and being able to slide relative to the drive shaft, one end of the connecting rod being fixed to the center of the surface of the drive gear, a protrusion being fixedly connected to the surface of the connecting rod, and a groove being formed inside the drive shaft, with the protrusion sliding left and right inside the groove.

[0011] Preferably, the sliding assembly includes a slide bar mounted on the surface of the support shaft, and a concave strip is installed inside the control box, with the surface of the slide bar slidably connected to the inner surface of the concave strip.

[0012] Preferably, the rotating assembly includes mounting plates symmetrically mounted at the bottom of the radar receiver, a sliding rod is installed between the mounting plates, and a sliding block is rotatably connected to the top of the support shaft via the rotating rod. The sliding block passes through the sliding rod and can slide relative to the sliding rod.

[0013] Preferably, the transverse rotation unit includes a rotating plate mounted on the surface of the drive shaft. A vertical rod is fixedly connected to the surface of the rotating plate, and a lower rotating block is fixedly mounted on the top of the vertical rod. An upper rotating block is mounted on the outer ring at the bottom of the radar receiver. A lower rotating rod is rotatably mounted inside the lower rotating block, and an upper rotating rod is rotatably mounted inside the upper rotating block. A moving groove is formed inside the upper rotating rod. A moving rod is mounted at one end of the lower rotating rod. The moving rod slides inside the moving groove, and a telescopic spring is fixedly mounted between the moving rod and the opposite side of the moving groove. An annular groove is formed on the top of the control box, and a rolling wheel is rotatably mounted on the surface of the vertical rod, and the rolling wheel rolls on the inner surface of the annular groove.

[0014] Preferably, the opening and closing operations of the drive motor and cylinder are controlled by a monitoring system. The monitoring system includes a command output unit, an output transmission module, an angle calculation unit, and a central processing unit. The command output unit is electrically connected to an external control panel. The output terminal of the command output unit is connected to the input terminal of the output transmission module. The output terminal of the output transmission module is connected to the input terminal of the angle calculation unit. The angle calculation unit is bidirectionally connected to the central processing unit. The central processing unit is bidirectionally connected to the radar receiver. The output terminal of the central processing unit is connected to the input terminal of the drive motor and cylinder and controls the opening and closing operations. The starting of the drive motor and cylinder controls the lateral and vertical rotation of the radar receiver.

[0015] This invention also discloses a monitoring method for a power quality monitoring system of a smart distributed energy power station, specifically including the following steps:

[0016] S1. Signal Positioning: First, the system positions the required receiving point and performs command operations based on the positioned space. The command output unit outputs the command from the output transmission module to the angle calculation unit for corresponding adjustment angle calculation, and transmits it to the central processing unit to control the opening and closing of the drive motor and cylinder to complete the horizontal and vertical rotation of the radar receiver.

[0017] S2, Lateral Adjustment: At this time, by starting the drive motor, the drive shaft is rotated, which in turn drives the rotating plate and the vertical rod to rotate. At this time, the rolling wheel slides inside the annular groove, and the radar receiver connected to the upper and lower rotating rods is adjusted in lateral angle.

[0018] S3. Vertical Adjustment: Simultaneously, the rotation of the drive shaft causes the auxiliary shaft to rotate through the transmission assembly. The auxiliary shaft, through the meshing of the meshing assembly, drives the transmission shaft to rotate. After the horizontal angle rotation is achieved, the vertical angle of the radar receiver is synchronously adjusted. Based on the calculated rotation angle, after the radar receiver rotates a certain angle horizontally, the cylinder is activated. The cylinder drives the connecting rod and the transmission gear to mesh with the surface of the transmission rack, thereby realizing the vertical movement of the support shaft. The vertical angle adjustment of the radar receiver is achieved by the sliding of the sliding rod and the sliding block.

[0019] Preferably, in step S3, when the radar receiver is vertically adjusted, the radar receiver drives the lower rotating rod to slide in the moving groove inside the upper rotating rod, extending the distance while rotating, and pulling the extension of the telescopic spring.

[0020] Beneficial effects

[0021] This invention provides a power quality monitoring system and method for intelligent distributed energy power stations. Compared with existing technologies, it has the following advantages:

[0022] (1) The power quality monitoring system and method of the smart distributed energy station, by setting up a receiving adjustment mechanism, uses a drive motor to drive the rotation of the drive shaft, and in conjunction with the transmission component, meshing component, pneumatic component and rotation component, realizes the vertical angle adjustment of the radar receiver, and realizes the horizontal angle adjustment through the horizontal rotation unit. Based on the calculation, the radar receiver can perform synchronous adjustment of the horizontal and vertical angles when receiving power quality monitoring signals of the energy station, thereby realizing the operation of accurate signal reception, improving the reception quality and monitoring efficiency.

[0023] (2) The power quality monitoring system and method of the smart distributed energy station is equipped with a horizontal rotation unit. The drive motor drives the rotation of the drive shaft, which in turn drives the rotation of the rotating plate and the vertical rod. At this time, the rolling wheel slides inside the annular groove, and the radar receiver connected to the upper and lower rotating rods is adjusted in the horizontal angle. This avoids the problem of horizontal rotation interference during vertical adjustment, and makes it easier to perform positioning adjustment operations, making the signal acquisition operation smoother and faster.

[0024] (3) The power quality monitoring system and method of the intelligent distributed energy station, by setting up a monitoring system, uses the space based on the positioning to perform command operation, and outputs the command from the output transmission module to the angle calculation unit to perform the corresponding adjustment angle calculation, and transmits it to the central processor to control the opening and closing of the drive motor and cylinder, and completes the horizontal and vertical rotation of the radar receiver, realizing intelligent monitoring operation, improving the efficiency and quality of monitoring, and making the power quality monitoring process of the energy station safer.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-10 This invention provides two technical solutions:

[0038] Example 1

[0039] The power quality monitoring system of the smart distributed energy station includes a monitoring instrument body 1, and a control box 2 is installed on the top of the monitoring instrument body 1. A control panel 3 is installed on the surface of the control box 2. The radar receiver 4 is rotated inside the control box 2 through a receiving adjustment mechanism 5. The receiving adjustment mechanism 5 is used to adjust the radar receiver 4 to rotate horizontally and vertically at the same time.

[0040] The receiving and adjusting mechanism 5 includes a drive motor 51 mounted at the bottom of the control box 2. The drive motor 51 is a three-phase asynchronous motor and is electrically connected to an external power source. One end of the output shaft of the drive motor 51 is fixedly connected to a drive shaft 52 via a coupling. The surface of the drive shaft 52 causes the auxiliary shaft 59 to rotate on a support plate inside the control box 2 via a transmission assembly 53. The top of the auxiliary shaft 59 causes the transmission shaft 510 to rotate via a meshing assembly 54. Inside the transmission shaft 510, a pneumatic assembly 55 causes the transmission gear 511 to rotate and move. The transmission shaft 510 is connected to the support plate inside the control box 2. The plate is fixed by a rotating bearing. Inside the control box 2, the support shaft 512 moves vertically through a sliding assembly 56. The support shaft 512 passes through the control box 2 and extends to the top of the control box 2, and can slide relative to the control box 2. The top of the support shaft 512 is connected to the bottom of the radar receiver 4 through a rotating assembly 57. A transmission rack 513 is installed on the surface of the support shaft 512. When the transmission gear 511 meshes with the surface of the transmission rack 513, the rotation of the transmission gear 511 enables the transmission rack 513 to move vertically. A transverse rotating unit 58 is provided on the surface of the drive shaft 52.

[0041] By incorporating a receiving adjustment mechanism 5, the drive motor 51 drives the drive shaft 52 to rotate. This, along with the transmission assembly 53, engagement assembly 54, pneumatic assembly 55, and rotation assembly 57, enables the radar receiver 4 to adjust its vertical angle. The horizontal angle adjustment is achieved through the horizontal rotation unit 58. Based on calculations, the radar receiver 4 can simultaneously adjust its horizontal and vertical angles when receiving power quality monitoring signals from energy plants, thereby achieving precise signal reception, improving reception quality, and enhancing monitoring efficiency.

[0042] In this embodiment of the invention, the transmission assembly 53 includes a drive wheel 53-1 fixedly mounted on the surface of the drive shaft 52 and an auxiliary drive wheel 53-2 fixedly mounted on the auxiliary drive shaft 59. The surfaces of the drive wheel 53-1 and the auxiliary drive wheel 53-2 are connected by a transmission belt 53-3.

[0043] In this embodiment of the invention, the meshing assembly 54 includes a first bevel gear 54-1 fixedly mounted on the surface of the auxiliary drive shaft 59, and a second bevel gear 54-2 fixedly connected to the surface of the drive shaft 510, with the surfaces of the first bevel gear 54-1 and the second bevel gear 54-2 meshing with each other.

[0044] In this embodiment of the invention, the pneumatic assembly 55 includes a cylinder 55-1 installed inside the control box 2. The cylinder 55-1 is connected to an external air circuit. A connecting rod 55-2 is rotatably mounted on the output end of the cylinder 55-1. One end of the connecting rod 55-2 passes through the transmission shaft 510 and can slide relative to the transmission shaft 510. One end of the connecting rod 55-2 is fixed to the center of the surface of the transmission gear 511. A protrusion 55-3 is fixedly connected to the surface of the connecting rod 55-2. A groove 55-4 is opened inside the transmission shaft 510, and the protrusion 55-3 slides left and right inside the groove 55-4.

[0046] In this embodiment of the invention, the rotating assembly 57 includes mounting plates 57-1 symmetrically mounted on the bottom of the radar receiver 4, with sliding rods 57-2 mounted between the mounting plates 57-1, and a sliding block 57-3 rotatably connected to the top of the support shaft 512 via a rotating rod. The sliding block 57-3 passes through the sliding rod 57-2 and can slide relative to the sliding rod 57-2.

[0047] In this embodiment of the invention, the transverse rotation unit 58 includes a rotating plate 58-1 mounted on the surface of the drive shaft 52. A vertical rod 58-2 is fixedly connected to the surface of the rotating plate 58-1, and a lower rotating block 58-3 is fixedly mounted on the top of the vertical rod 58-2. An upper rotating block 58-4 is mounted on the outer ring of the bottom of the radar receiver 4. A lower rotating rod 58-5 is rotatably mounted inside the lower rotating block 58-3, and an upper rotating rod 58-6 is rotatably mounted inside the upper rotating block 58-4. A moving groove 58-7 is formed inside the upper rotating rod 58-6. A movable rod 58-8 is installed at one end of the -5. The movable rod 58-8 slides inside the movable groove 58-7. A telescopic spring 58-9 is fixedly installed between the movable rod 58-8 and the opposite side of the movable groove 58-7. The telescopic spring 58-9 is used to facilitate the reset operation of the lower rotating rod 58-5 and the upper rotating rod 58-6 without the influence of other external forces. An annular groove 58-10 is opened on the top of the control box 2. A rolling wheel 58-11 is rotatably installed on the surface of the vertical rod 58-2, and the rolling wheel 58-11 rolls on the inner surface of the annular groove 58-10.

[0048] By setting up a horizontal rotation unit 58, the drive motor 51 drives the drive shaft 52 to rotate, which in turn drives the rotating plate 58-1 and the vertical rod 58-2 to rotate. At this time, the rolling wheel 58-11 slides inside the annular groove 58-10, and the radar receiver 4 connected to the upper rotating rod 58-6 and the lower rotating rod 58-5 can be adjusted in the horizontal angle. This avoids the problem of horizontal rotation interference during vertical adjustment, and makes it easier to perform positioning adjustment operations, making the signal acquisition operation smoother and faster.

[0049] In this embodiment of the invention, the opening and closing operations of the drive motor 51 and the cylinder 55-1 are controlled by a monitoring system. The monitoring system includes an instruction output unit, an output transmission module, an angle calculation unit, and a central processing unit. The instruction output unit is electrically connected to an external control panel. The output end of the instruction output unit is connected to the input end of the output transmission module. The output end of the output transmission module is connected to the input end of the angle calculation unit. The angle calculation unit is bidirectionally connected to the central processing unit. The central processing unit is bidirectionally connected to the radar receiver 4. The output end of the central processing unit is connected to the input end of the drive motor 51 and the cylinder 55-1 and controls the opening and closing operations. The starting of the drive motor 51 and the cylinder 55-1 controls the horizontal and vertical rotation of the radar receiver 4.

[0050] By setting up a monitoring system, commands are executed based on the spatial positioning. The command output unit outputs commands from the output transmission module to the angle calculation unit for corresponding adjustment angle calculation, and transmits them to the central processing unit to control the opening and closing of the drive motor 51 and cylinder 55-1, thereby completing the lateral and vertical rotation of the radar receiver 4. This achieves intelligent monitoring operation, improves monitoring efficiency and quality, and makes the power quality monitoring process in energy plants safer.

[0051] This invention also discloses a monitoring method for a power quality monitoring system of a smart distributed energy power station, specifically including the following steps:

[0052] S1. Signal positioning: First, the system locates the required receiving point and performs command operations based on the positioned space. The command output unit outputs the command from the output transmission module to the angle calculation unit for corresponding adjustment angle calculation, and transmits it to the central processing unit to control the opening and closing of the drive motor 51 and cylinder 55-1 to complete the horizontal and vertical rotation of the radar receiver 4.

[0053] S2, Lateral Adjustment: At this time, by starting the drive motor 51, the drive motor 51 drives the drive shaft 52 to rotate, which in turn drives the rotating plate 58-1 and the vertical rod 58-2 to rotate. At this time, the rolling wheel 58-11 slides inside the annular groove 58-10, and the radar receiver 4 connected to the upper rotating rod 58-6 and the lower rotating rod 58-5 is adjusted to the lateral angle.

[0054] S3. Vertical Adjustment: Simultaneously, the rotation of the drive shaft 52 causes the auxiliary shaft 59 to rotate through the transmission assembly 53. The auxiliary shaft 59 drives the transmission shaft 510 to rotate through the meshing assembly 54. After the horizontal angle rotation is achieved, the vertical angle of the radar receiver 4 is synchronously adjusted. According to the calculated rotation angle, after the radar receiver 4 rotates horizontally by a certain angle, the cylinder 55-1 is activated. The cylinder 55-1 drives the connecting rod 55-2 and the transmission gear 511 to mesh with the surface of the transmission rack 513, thereby realizing the vertical movement of the support shaft 512. The vertical angle adjustment of the radar receiver 4 is achieved by the sliding of the sliding rod 57-2 and the sliding block 57-3.

[0055] In S3, when the radar receiver 4 is vertically adjusted, the radar receiver 4 drives the lower rotating rod 58-5 to slide in the moving groove 58-7 inside the upper rotating rod 58-6, extending the distance while rotating, and pulling the extension of the telescopic spring 58-9.

[0056] Example 2

[0057] The difference from Example 1 is as follows:

[0058] The specific implementation method of the angle calculation unit is as follows:

[0059] Based on the collected positioning data, adjustments are achieved through spatial and distance measurements by the monitoring system. First, the required movement in the horizontal and vertical angles is calculated using the Pythagorean theorem in the plane. It is assumed that the horizontal and vertical rotations are the same. Therefore, during angle adjustment, the excess horizontal rotation is first achieved by the drive motor 51. When the horizontal and vertical rotations are the same, the cylinder 55-1 drives the connecting rod 55-2 and the transmission gear 511 to mesh with the surface of the transmission rack 513, thereby achieving synchronous adjustment of the subsequent horizontal and vertical angles until the required monitoring positioning point is reached.

A monitoring method for the power quality monitoring system of the smart distributed energy station as described in claim 6, characterized in that: Specifically, the following steps are included: S1, Signal Positioning: First, the system positions the required receiving point and performs command operations based on the positioned space. The command output unit outputs the command from the output transmission module to the angle calculation unit to perform the corresponding adjustment angle calculation, and transmits it to the central processing unit to control the opening and closing of the drive motor (51) and cylinder (55-1) to complete the horizontal and vertical rotation of the radar receiver (4). S2, Lateral Adjustment: At this time, by starting the drive motor (51), the drive motor (51) drives the drive shaft (52) to rotate, and drives the rotating plate (58-1) and the vertical rod (58-2) to rotate. At this time, the rolling wheel (58-11) slides inside the annular groove (58-10), and realizes the lateral angle adjustment of the radar receiver (4) connected to the upper rotating rod (58-6) and the lower rotating rod (58-5). S3, Vertical Adjustment: At the same time, the rotation of the drive shaft (52) causes the auxiliary shaft (59) to rotate through the transmission assembly (53), and the auxiliary shaft (59) drives the transmission shaft (510) to rotate through the meshing of the meshing assembly (54). After the horizontal angle rotation is achieved, the vertical angle of the radar receiver (4) is synchronously adjusted. According to the calculated rotation angle, after the radar receiver (4) rotates horizontally by a certain angle, the cylinder (55-1) is started. The cylinder (55-1) drives the connecting rod (55-2) and the transmission gear (511) to mesh with the surface of the transmission rack (513), thereby realizing the vertical movement of the support shaft (512). The vertical angle adjustment of the radar receiver (4) is achieved by sliding the sliding rod (57-2) and the sliding block (57-3).

8. The power quality monitoring method for smart distributed energy stations according to claim 7, characterized in that: In S3, when the radar receiver (4) is vertically adjusted, the radar receiver (4) drives the lower rotating rod (58-5) to slide in the moving groove (58-7) inside the upper rotating rod (58-6), extending the distance while rotating, and pulling the extension of the telescopic spring (58-9).
