The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0040] As a pollution-free, renewable energy, wind energy has received widespread attention worldwide. Due to its renewability and environmental friendliness, wind energy is seen as one of the important solutions to address climate change and reduce dependence on traditional energy. Globally, wind power generation has developed rapidly and has become one of the most competitive renewable energy sources. Wind power generation has broad development prospects.

[0041] In the wind power generation system, the pitch control system is one of the important components of the wind turbine. Its main function is to control the angle of the blades to optimize the capture and conversion efficiency of wind energy. The pitch control system automatically adjusts the angle of the blades according to parameters such as wind speed, wind direction and the operating status of the generator set, so that it always remains in the best position to maximize the capture of wind energy and convert it into electrical energy.

[0042] The stability and accuracy of the pitch control system are crucial to the efficiency and reliability of wind power generation. It can adjust the angle of the blades in time according to the real-time changes in wind speed and direction to ensure that the wind turbine can operate normally under different wind speed conditions and operate within the optimal working range. In addition, the pitch control system can also protect the wind turbine, for example, when the wind speed is too high or a fault occurs, timely measures can be taken to protect the safe operation of the unit.

[0043] There are several types of pitch change modes: automatic pitch change: normal operation, controlled by the program; manual pitch change: used for debugging and maintenance, only when the position of two blades is around 86 degrees, the third blade can be changed to 0 degrees; forced manual pitch change: used for debugging and maintenance, all three blades can be changed to 0 degrees, not limited to 86 degrees.

[0044] To facilitate daily maintenance and overhaul, the pitch control system needs to be switched to the forced manual mode. At present, the operation method of the forced manual pitch control mode of the 1.5MW wind turbine pitch control system is: turn the manual / automatic knob of the pitch control cabinet from the "automatic" position to the "manual" position to switch from the automatic mode to the manual mode, and then insert the short-circuit pieces on the 8th and 9th terminals of the target terminal row in the pitch control cabinet into the 5th and 6th terminals to switch from the manual mode to the forced manual mode.

[0045] However, the current method of switching from manual mode to forced manual mode by using a short-circuit to enter the forced manual pitch mode is inconvenient to operate, and long-term plugging and unplugging of the short-circuit will damage the terminal block and the short-circuit of the pitch control cabinet, resulting in the defect of shortening the service life of the terminal block.

[0046] In response to the above problems, the present application provides a 1.5MW wind turbine forced manual pitch control system, the pitch control system comprising: a pitch control cabinet, the pitch control cabinet comprising a target terminal block and a button switch device, the target terminal block comprising: a first wiring port and a second wiring port, one end of the button switch device is connected to the first wiring port, and the other end is connected to the second wiring port, the pitch control system controls the on-off state between the first wiring port and the second wiring port through the button switch device to control the blades corresponding to the pitch control cabinet to enter the forced manual pitch mode, thereby avoiding the defect that the terminal block and the short circuit piece are easily damaged in the method of entering the forced manual pitch mode through a short circuit piece in the prior art, and the pitch control system is easy to operate when switching to the forced manual pitch mode, thereby improving the user experience.

[0047] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0048] The 1.5MW wind turbine generator set forced manual pitch control system provided in this embodiment includes three pitch control cabinets.

Figure 1 As shown, the pitch control cabinet can be, for example, a KL1104 pitch control cabinet. The digital input terminals of the KL1104 pitch control cabinet obtain binary control information from the field devices and transmit the data to the higher-level automation unit in the form of electrically isolated signals. Each bus terminal of the KL1104 pitch control cabinet contains 4 channels, and each channel has an LED indicator to indicate the current signal status.

[0049] It can be understood that the three pitch control cabinets are respectively used to control the operation of the three blades of the wind turbine. The pitch control cabinet shown in this embodiment can be any one of the three pitch control cabinets. Each pitch control cabinet in the forced manual pitch control system of the wind turbine generator set includes multiple terminal rows, and different terminal rows have different functions. Among them, the terminal row in the pitch control cabinet used to control the switching of the forced manual pitch control mode is the target terminal row shown in this embodiment.

[0050] Figure 2 This is a schematic diagram of the pitch control system provided in this application. Figure 2 As shown, the schematic diagram of the pitch control system shown in this embodiment includes: a target terminal block 1 and a button switch device 2, and the target terminal block 1 includes: a first wiring port 11 and a second wiring port 12.

[0052] When the blades corresponding to the pitch control cabinet need to enter the forced manual pitch control mode, the control button switch device can be turned on to make the first wiring port and the second wiring port connected, so that the blades corresponding to the pitch control cabinet complete the switch from the manual pitch mode to the forced manual pitch mode; when the blades corresponding to the pitch control cabinet need to exit the forced manual pitch control mode, the control button switch device can be switched from the on state to the off state to make the first wiring port and the second wiring port connected from the connected state to the disconnected state, so that the blades corresponding to the pitch control cabinet complete the switch from the forced manual pitch mode to the manual pitch mode.

[0053] The 1.5MW wind turbine forced manual pitch control system provided in the present embodiment controls the button switch device to be in an on or off state so that the first wiring port and the second wiring port are in an on or off state, thereby controlling the blades corresponding to the pitch control cabinet to switch to forced manual pitch mode or manual pitch mode, avoiding the defect of the prior art that the short circuit chip needs to be repeatedly plugged and unplugged for a long time, thereby shortening the service life of the terminal block, and achieving the effect of quickly and conveniently switching the blades to the forced manual pitch mode, and during the switching process, there will be no problem of damaging the terminal block of the pitch control cabinet.

[0055] When the control unit 21 is in the on state, the prompt unit 22 connected in series with the control unit 21 is in the on state, so it will prompt that the current first wiring port 11 and the second wiring port 12 are in the on state, and the blades corresponding to the pitch control cabinet can enter the forced manual pitch mode; when the control unit 21 is in the off state, the prompt unit 22 connected in series with the control unit 21 is in the off state, so it will prompt that the current first wiring port 11 and the second wiring port 12 are in the disconnected state, and the blades corresponding to the pitch control cabinet can enter the automatic pitch mode.

[0056] Optionally, the pitch control cabinet further includes: a first setting track, a second setting track and a track slot;

[0057] The target terminal block 1 is fixedly connected to the first setting track and is clamped on the track slot through the first setting track. The push button switch device 2 is fixedly connected to the second setting track and is clamped on the track slot through the second setting track. The first setting track, the second setting track and the track slot provide control and management functions for the forced manual pitch control system of the wind turbine. The slot track installation allows the control cabinet to be easily maintained and operated, and ensures the safe and reliable operation of the system.

[0058] Optionally, the first wiring port 11 and the second wiring port 12 are located in the middle part of the target terminal row 1, and the first wiring port 11 is adjacent to the second wiring port 12. The purpose of this setting is to facilitate wiring and avoid the disorder of wires. At the same time, it avoids the situation where the operation of other lines is affected when there is a fault in the line.

[0059] Optionally, the prompt unit 22 may be a prompt light.

[0061] Figure 5 This is a schematic diagram of the structure of the control unit of the switch button device provided in this application. Figure 5 As shown, the control unit 21 of the switch button device 2 provided in this embodiment includes: a button cap 2101, a first return spring 2102, a second return spring 2103, a third return spring 2104, a first fixed contact 2105, a second fixed contact 2106, a first filling block 2107, a second filling block 2108, a movable contact 2109, a support link 2110, a first fixing device 2111, and multiple second fixing devices 2112.

[0062] The return spring includes a first return spring 2102 , a second return spring 2103 , a third return spring 2104 , a first filling block 2107 and a second filling block 2108 .

[0063] The first return spring 2102, the second return spring 2103, the third return spring 2104, the first filling block 2107, the second filling block 2108, the first fixed contact 2105, the second fixed contact 2106, the movable contact 309 and the support link 310 are arranged inside the shell, and the button cap 2101 is arranged outside the shell.

[0064] One end of the support link 2110 is fixedly set at the bottom of the shell, and the return spring includes a first return spring 2102, a second return spring 2103, a third return spring 2104, a first filling block 2107 and a second filling block 2108, which are sleeved on the support link 2110. One end of the first return spring 2102, the second return spring 2103, the third return spring 2104, the first filling block 2107 and the second filling block 2108 abuts against the button cap 2101, and the other end is fixedly connected to the movable contact 2109.

[0065] The first fixed contact 2105 and the second fixed contact 2106 are both fixedly disposed on the inner side of the housing, and the first fixed contact 2105 is disposed above the movable contact 2109 along the vertical direction, and the second fixed contact 2106 is disposed below the movable contact 2109 along the vertical direction.

[0066] Optionally, one end of the first return spring 2102 abuts against the button cap 2101 , and the other end abuts against one end block of the first filling block 2107 , and the other end of the first filling block 2107 abuts against one end of the second return spring 2103 .

[0067] The first fixing device 2111 is disposed between the second return spring 2103 and the second filling block 2108 . The first fixing device 2111 is used to fix the movable contact 2109 so that the movable contact 2109 and the second return spring 2103 can move relative to each other.

[0068] One end of the second filling block 2108 abuts against one end of the third return spring 2104 , and the other end of the third return spring 2104 is fixedly disposed at the bottom of the housing.

[0069] Optionally, a plurality of second fixing devices 2112 are fixedly disposed on the inner side surface of the housing, and the plurality of second fixing devices 2112 are used to fix the first fixed contact 2105 and the second fixed contact 2106 on the inner side surface of the housing.

[0070] Optionally, when the button cap 2101 is pressed, the second fixed contact 2106 contacts the movable contact 2109 driven by the second return spring 2103, and a passage is formed between the first fixing device 2111, the second fixed contact 2106, the movable contact 2109 and the first fixed contact 2105 corresponding to the movable contact.

[0071] It can be understood that when the user presses the button cap 2101, the button cap 2101 will push the first return spring 2102 to move downward in the vertical direction as a whole, and the first return spring 2102 moves downward in the vertical direction as a whole to squeeze the first filling block 2107. After the first filling block 2107 is squeezed, it moves downward in the vertical direction to squeeze the second return spring 2103. After the second return spring 2103 is squeezed, it moves downward in the vertical direction to drive the movable contact 2109 to contact the second fixed contact 2106. At this time, a passage is formed between the first fixing device 2111, the second fixed contact 2106, the movable contact 2109, and the first fixed contact 2105 corresponding to the movable contact 2109. At this time, the button opening device 2 is in the open state, the first wiring port 11 of the target terminal row 1 is connected to the second wiring port 12, and the blade corresponding to the pitch control cabinet enters the forced manual pitch mode.

[0072] Among them, the first return spring 2102 in the support link 2110 has card slots on both sides, so that when the user presses the button cap 2101, the first return spring 2102 can be stuck in the card slot, so that the first return spring 2102 can continuously squeeze the first filling block 2107, so that the first filling block 2107 can continuously squeeze the second return spring 2103, so that the second return spring 2103 drives the movable contact 2109 to contact the second fixed contact 2106 under continuous squeezing, and maintains a continuous passage between the first fixing device 2111, the second fixed contact 2106, the movable contact 2109 and the first fixed contact 2105 corresponding to the movable contact 2109.

[0073] It can be understood that when the user presses the button cap 2101 again, the button cap 2101 will push the first return spring 2102 to move downward in the vertical direction as a whole, and the first return spring 2102 is no longer stuck in the slot, so that the first return spring 2102 is released and returns to its original position. With the release of the first return spring 2102, the first filling block 2107 is no longer squeezed and returns to its original position. The release of the first filling block 2107 makes the second filling block 2103 no longer squeezed and returns to its original position. The release of the second filling block 2103 separates the movable contact 2109 from the second fixed contact 2106, breaking the contact. After the movable contact 2109 is separated from the second fixed contact 2106, the path between the first fixing device 2111, the second fixed contact 2106, the movable contact 2109 and the first fixed contact 2105 corresponding to the movable contact 2109 is interrupted. At this time, the button switch device 2 is in the closed state, the first wiring port 11 and the second wiring port 12 of the target terminal block 1 are disconnected, and the blades corresponding to the pitch control cabinet enter the automatic pitch mode.
