Description

Technical Field

[0001] The present invention relates to, but is not limited to, automatic control technology, and in particular to a monitoring system and method for a wind turbine generator set. Background Art

[0002] At present, the global installed capacity of wind turbines is constantly increasing. Although the failure rate of wind turbines has decreased with the improvement of technology, it still exists.

[0003] At present, fan failure is mathematically judged based on the calculation logic inside the fan main control program. When the real-time data of the main control logic midpoint determines a failure, the failure point will be reported to the operation and maintenance personnel. The operation and maintenance personnel will know the specific failure of the fan, such as gearbox temperature failure, generator winding temperature failure, fan yaw failure, etc.

[0004] However, fan fault judgment is based on the calculation logic inside the fan main control program. If the fault is caused by a failure of the main control equipment itself, the fan cannot be reset no matter how the operation and maintenance personnel perform remote operations. It is more likely that the operation and maintenance personnel will need to go inside the fan cabin for confirmation, which will waste time. Summary of the invention

Among them, the wind turbine generator may be referred to as a wind turbine. Figure 1 Multiple fans in: fan 1, fan 2...fan M, M≥1.

[0025] In this embodiment, the remote online diagnosis function of SCADA can be applied to the wind power system to monitor the main control hardware module of the control device in the wind turbine generator set and display the fault diagnosis.

[0026] Each wind turbine generator set is provided with a set of control devices, and each set of control devices is used to control the operation of the wind turbine generator set to which it belongs; multiple wind turbine generator sets are arranged in the same local area network, and each controller is connected to SCADA through the local area network.

[0027] In practical applications, multiple wind turbines can form a wind farm to achieve wind power generation. In this embodiment, multiple wind turbines can be set in the same local area network, that is, the wind farm composed of multiple wind turbines is set as a certain "domain" to perform centralized management and decentralized control of the wind turbines.

[0028] In this embodiment, a set of control devices may be provided in each wind turbine generator set to control the operation of the wind turbine generator set in which it is located. SCADA may be connected to each set of control devices to monitor the operation of multiple wind turbine generator sets in the same local area network, and to implement the monitoring of the main control hardware modules of the control devices in the wind turbine generator set and the display of fault diagnosis.

[0029] In one example, the local area network may be a wired local area network, and each controller may be connected to the SCADA through the network, thereby realizing a wired network connection between the controller and the SCADA.

[0030] Each set of control devices may include: a controller 121 and a plurality of hardware main control modules 122 . The hardware main control module refers to a hardware module that can provide wind turbine data to the controller, and the controller is connected to each hardware main control module respectively.

[0031] In this embodiment, the controller and each hardware main control module can be respectively plugged into the backplane to achieve electrical connection between the controller and each hardware main control module.

[0032] In this embodiment, each set of control devices, that is, a set of main control systems of a wind turbine generator set, may include a controller and at least one hardware main control module. The hardware main control module and the controller may be respectively installed in the accommodation space of the wind turbine generator set. The hardware main control module may be connected to the inside of the wind turbine generator set by hard wiring to collect or transmit data, which is then transmitted to the controller in the wind turbine main control system and finally displayed in the SCADA system.

[0033] The hardware main control module can collect or transmit relevant wind turbine data. Among them, the wind turbine data may include relevant operating data of the variable pitch system and / or the converter, for example, the wind turbine data may include: the speed of the variable pitch system and the frequency conversion data of the converter and other control data, or the wind turbine data may include: the maximum temperature of the relevant variable pitch shaft box of the variable pitch system, the minimum value of the blade position, the stator voltage value of the converter and the maximum temperature of the grid-side module and other information data.

[0034] In one example, the accommodation space of the wind turbine generator set may include a nacelle and a tower bottom, the controller may be arranged at the tower bottom, and the hardware main control module may be arranged at the nacelle or the tower bottom.

[0035] The controller is used to detect the operating status of each connected hardware main control module, and send the identification of each hardware main control module and the display information matching the operating status of the hardware main control module to the SCADA.

[0036] In this embodiment, the controller detects the operating status of each connected hardware main control module to determine whether the hardware main control module is operating normally, offline or faulty, and determines or obtains display information that matches the operating status of the hardware main control module, sends the matching display information to SCADA, and displays the operating status of the corresponding hardware main control module on SCADA in different ways.

[0037] In one example, the display information may include, but is not limited to: display color, display shape or sound. In this embodiment, different display colors, display shapes or sounds may be used to display the operating status of the corresponding hardware main control module.

[0038] Different operating states of the hardware main control module can be represented by different display colors; or different operating states of the hardware main control module can be represented by different display shapes; or different operating states of the hardware main control module can be represented by different sounds. The following embodiment is mainly described by using different display colors to represent different operating states of the hardware main control module. The implementation principle of using different display shapes or different sounds to represent different operating states of the hardware main control module is similar, and this embodiment will not be repeated one by one.

[0039] In this embodiment, the hardware main control module inside the main control system of the wind turbine generator set and its host computer SCADA can be combined to detect the operating status of each hardware main control module inside the main control system through the controller in the main control system of the wind turbine generator set. The operating status of each hardware main control module can be directly displayed on the host computer SCADA monitoring interface, and the display icon corresponding to the operating status of each hardware main control module will have obvious color changes, shape changes or sound changes. Through the color change, shape change or sound change of the corresponding display icon on the SCADA monitoring interface, the operation and maintenance personnel can clearly know the operating status of each hardware main control module inside the main control system, such as whether the hardware main control module is running normally, offline or faulty; and when the hardware main control module fails, it can lock which specific hardware main control module has failed, and can lock the main control system fault module as soon as possible, saving the time of the operation and maintenance personnel to handle the fault, and the wind turbine can return to normal as soon as possible, indirectly increasing the number of hours available for the wind turbine and increasing the power generation of the wind turbine.

[0040] In one example, the controller may pre-store the identifier of each connected hardware main control module, or the controller may communicate with each connected hardware main control module to obtain the identifier of each connected hardware main control module.

[0041] The identification of the hardware main control module may include, but is not limited to: a hardware address, an Internet Protocol Address (IP address) or a number of the hardware main control module, and the hardware address is used to indicate the installation location of the hardware main control module.

[0042] SCADA is provided with display icons corresponding to each hardware main control module in multiple control devices, and the layout of the display icons is consistent with the layout of the hardware main control modules in the control devices; SCADA is used to display the display icon of at least one hardware main control module according to the received display information.

[0043] In this embodiment, the number of hardware main control modules and the actual layout of the hardware main control modules can be pre-determined on the SCADA monitoring interface, and the display icons corresponding to each hardware main control module in the multiple control devices are arranged on the SCADA monitoring interface, and the layout of the display icons corresponding to each hardware main control module in the monitoring interface is consistent with the actual layout of the hardware main control modules. Figure 1 To.

[0044] In this embodiment, a remote online diagnosis function can be added to the wind turbine generator set to support remote online display of the operating status of each hardware main control module in the main control system, and to support remote diagnosis of module failures and communication port failures in the main control system. A unique module self-check screen is set in the host computer SCADA monitoring system. When a hardware main control module fails, the corresponding display icon on the screen will have obvious color changes, shape changes or sound changes, which can be displayed intuitively on the SCADA, making it convenient for operation and maintenance personnel to timely lock the module fault and carry out subsequent processing.

[0045] The monitoring system of the wind turbine generator set disclosed in the embodiment of the present invention combines the main control system in the wind turbine generator set with the upper computer SCADA monitoring system, and can realize the operation status monitoring of each hardware main control module inside the main control system in the wind turbine generator set, filling the gap of the internal module monitoring of the main control system in the wind power industry. And the operation status monitoring of each hardware main control module inside the main control system is introduced into the wind turbine SCADA system, and the operation and maintenance personnel can intuitively see the operation status of each hardware main control module inside each main control system. And if the hardware main control module inside the main control system fails, the operation and maintenance personnel can lock the fault in time and handle the fault, especially the fault of the hardware main control module set in the cabin can be locked in time, which can avoid the operation and maintenance personnel from entering the cabin to confirm the fault, saving precious time for the wind turbine fault handling, indirectly increasing the number of hours that the wind turbine can be used and increasing the power generation of the wind turbine.

[0046] In an exemplary embodiment of the present invention, different operating states of the hardware main control module are represented by different display colors. In this embodiment, the corresponding relationship between the operating state of the hardware main control module and the display color can be preset, or the corresponding relationship between the identification of the hardware main control module, the operating state of the hardware main control module and the display color can be preset, and different operating states of the hardware main control module can be represented by different display colors in SCADA, so that operation and maintenance personnel can intuitively and timely know the operating state of each hardware main control module.

[0047] In one example, the operating status of the hardware main control module may include: the hardware main control module is operating normally, the hardware main control module is offline, or the hardware main control module is faulty;

[0048] The display color of the hardware main control module running normally can be green, the display color of the hardware main control module offline matching can be blue, and the display color of the hardware main control module fault matching can be yellow.

[0049] In this embodiment, green, blue and yellow may be used to indicate that the hardware main control module is operating normally, the hardware main control module is offline and the hardware main control module is faulty.

[0050] In an exemplary embodiment of the present invention, the hardware main control module may include at least one of the following: an acquisition card for acquiring wind turbine data and a communication card for transmitting wind turbine data. In this embodiment, the hardware main control module may include an IO acquisition card or a communication card.

[0051] Figure 2 The module layout diagram in the SCADA system provided by the embodiment of the present invention is as follows: Figure 2 As shown in the figure, the hardware main control module can include acquisition cards such as DI, DO, AI, AO, RTD and SSI, which are used to collect the actual device information in the fan body. Among them, DI is used to collect switch input information, DO is used to collect switch output information, AI is used to collect analog input information, AO is used to collect analog output information, and RTD is used to collect temperature signals. In addition, there can also be some special cards, such as SSI for encoder information collection and CAN for CAN communication data collection.

[0052] like Figure 2 As shown, the display icons corresponding to the hardware main control module in SCADA may include: character indicator icons (such as Figure 2 DI in the figure, etc.) and a display indication icon D, the display indication icon D may be a color display icon, a shape display icon or a sound display icon, the color indication icon D may be but is not limited to including an indicator light, a shape icon or a buzzer.

[0053] In this embodiment, the controller and each hardware main control module can be respectively inserted into the slots of the backplane to realize the electrical connection between the controller and each hardware main control module. Among them, the controller needs to occupy two slots, and one hardware main control module occupies one slot.

[0054] in, Figure 2 The layout quantity and layout position of the controller and the hardware main control module in the module layout diagram of the SCADA system shown are only examples, and the specific layout quantity and layout position can be determined according to the actual installation quantity and installation position.

[0055] In an exemplary embodiment of the present invention, the controller detects the operating status of each connected hardware main control module, which may include:

[0056] For each connected hardware main control module, the controller detects whether the hardware address of the hardware main control module can be obtained; if the hardware address of the hardware main control module is obtained and the hardware address is the set hardware address, it is determined that the hardware main control module is operating normally.

[0057] Each hardware main control module corresponds to a hardware address, and the hardware address is used to indicate the installation location of the hardware main control module.

[0058] In this embodiment, the controller can communicate with each connected hardware main control module to detect whether the hardware address of the connected hardware main control module can be obtained. If the hardware address of the connected hardware main control module can be obtained and the obtained hardware address is valid, it is determined that the communication is normal and the connected hardware main control module is operating normally. When all the hardware main control modules are operating normally, the display icons corresponding to all the hardware main control modules in SCADA are displayed in green.

[0059] Among them, the hardware address is valid when the hardware address is the set hardware address, or the value of the hardware address is greater than the set value. Figure 2 As shown, if the obtained hardware address is valid, for example, the obtained hardware address of the RTD module is the set hardware address B1, or the obtained hardware address of the RTD module is greater than 0, it is determined that there is a hardware main control module at the location of the hardware address, and the slot where the hardware main control module is located is not empty, then the display icon in SCADA is displayed in green, indicating that the card communication is normal.

[0060] In an exemplary embodiment of the present invention, the controller detects the operating status of each connected hardware main control module, which may include:

[0061] For each connected hardware main control module, the controller detects the communication status with the hardware main control module respectively; when the communication between the controller and the hardware main control module times out, it is determined that the hardware main control module is offline; when the controller and the hardware main control module cannot communicate, it is determined that the hardware main control module is faulty.

[0062] In this embodiment, the controller can communicate with each connected hardware main control module to detect whether the communication has timed out or cannot communicate, so as to determine whether the connected hardware main control module is offline or faulty. Among them, the implementation principle of the controller detecting whether the communication with each connected hardware main control module has timed out or cannot communicate (communication error) is the same as the existing scheme, and this embodiment is not limited or elaborated here. For example, the controller can send a communication request to the hardware main control module. If the time when the controller receives the feedback information of the hardware main control module and the time when it sends the communication request exceed the set time value, it is determined that the communication has timed out; if the controller does not receive the feedback information of the hardware main control module, or the feedback information received from the hardware main control module indicates a communication error, it is determined that the communication cannot be communicated.

[0063] If the controller does not communicate effectively with a hardware master control module (such as a DI card) within the allowed time, that is, the communication between the controller and a hardware master control module (such as a DI card) connected to it times out, it is determined that the connected hardware master control module (such as a DI card) is offline, and the offline is due to the module falling off due to vibration inside the cabinet or poor contact of the hardware master control module. At this time, the color of the display icon corresponding to the offline hardware master control module (such as a DI card) in SCADA is blue, and the color of the display icons corresponding to the other hardware master control modules with normal communication is still green.

[0064] If the controller cannot communicate with a certain hardware main control module (such as a DI card) connected to it or the communication is wrong, it is determined that the connected hardware main control module (such as a DI card) is faulty, and the fault is due to the hardware fault of the hardware main control module itself, resulting in the inability to communicate or a communication error. At this time, the color of the display icon corresponding to the faulty hardware main control module (such as a DI card) in SCADA is yellow, and the color of the display icons corresponding to the other hardware main control modules with normal communication is still green.

[0067] S302: SCADA displays a display icon of at least one hardware main control module according to the received display information.

[0068] Among them, each wind turbine generator set is equipped with a set of control devices, and each set of control devices is used to control the operation of the wind turbine generator set to which it belongs; each set of control devices includes: a controller and multiple hardware main control modules, and the hardware main control module refers to a hardware module that can provide wind turbine data to the controller; multiple wind turbine generator sets are arranged in the same local area network, and each controller is connected to SCADA through the local area network; SCADA is provided with display icons corresponding to each hardware main control module in multiple sets of control devices, and the layout of the display icons is consistent with the layout of the hardware main control modules in the control devices.
