Description

Technical Field

[0001] The present invention belongs to the technical field related to new energy equipment control, and specifically relates to a wind turbine control system based on an IPC hardware platform. Background Art

[0002] With the continuous development of wind power generation technology, the capacity of wind turbines continues to increase, and the operating environment becomes more complex, which puts higher demands on the performance of control systems. Currently, there are still many technical problems in the actual application of wind turbine control systems:

[0003] In terms of communication, traditional control systems use fixed parameter communication methods and cannot be dynamically adjusted according to factors such as the electromagnetic environment of the wind farm and transmission distance. When multiple units are running simultaneously in a wind farm, signal interference is likely to occur, resulting in an increase in the communication bit error rate. In some scenarios, the bit error rate can even reach 10 -4 , which seriously affects the accuracy of data transmission, and then causes deviations in the execution of control instructions, reducing the operating efficiency of the unit.

[0004] In terms of data processing, the existing system's data collection frequency and processing algorithm were relatively fixed, and could not be flexibly adjusted based on the unit's operating status. During conditions such as unit startup and shutdown, or when encountering gusty winds, operating data fluctuated dramatically. The fixed collection frequency made it difficult to capture key data changes, resulting in data processing results that did not truly reflect the unit's actual operating conditions, impacting the scientific nature of control decisions. Furthermore, the presence of redundant data increased the system's processing burden and prolonged data processing delays, with some systems experiencing delays exceeding 100ms.

[0005] In terms of safety protection, traditional systems often rely on single-parameter thresholds for safety assessments, lacking comprehensive analysis of multiple parameters. When complex faults occur in a turbine, these systems often fail to accurately identify them in a timely manner, leading to delayed safety warnings and even accidents. Statistics show that for wind turbines using traditional control systems, failures due to untimely safety warnings account for over 30% of total downtime, resulting in significant economic losses.

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] The present invention provides a technical solution: a wind turbine control system based on an IPC hardware platform, comprising:

[0025] Communication parameter collection and analysis module, used to collect communication parameters of wind turbines and analyze the communication parameters;

[0026] An operation data processing process parameter acquisition and analysis module is used to acquire the processing process parameters of the wind turbine operation data and analyze the processing process parameters;

[0027] A safety anomaly warning set matching and execution module is used to collect wind turbine operating data, match the operating data with a preset safety anomaly warning set, and execute corresponding warnings and processing measures;

[0028] The IPC hardware platform is respectively connected to the communication parameter acquisition and analysis module, the operation data processing process parameter acquisition and analysis module, and the safety anomaly warning set matching and execution module, and is used to process, store data and send control instructions.

[0029] The specific implementation is as follows:

[0030] System installation and initialization

[0031] The signal acquisition terminals of the communication parameter acquisition and analysis module are installed in the nacelle of the wind turbine, the control cabinet at the bottom of the tower and the communication interface with the remote monitoring center. The acquisition terminals are connected to the centralized analysis unit through shielded cables, and the centralized analysis unit communicates with the IPC hardware platform through Ethernet.

[0032] The parameter acquisition and analysis module for the operation data processing process is connected to the sensors of the unit through a data acquisition card. The acquisition card supports 8-channel analog input and 16-channel digital input. The module is connected to the IPC hardware platform through a PCIe interface.

[0033] The safety abnormality warning set matching and execution module receives data from each module through the internal bus, and its output end is connected to the alarm device and actuator (such as the pitch system and braking system) of the unit.

[0034] The IPC hardware platform is installed in the control cabinet at the bottom of the tower. After the power is turned on, the system is initialized and the initial parameters of each module are set, such as the initial communication signal strength threshold is -85dBm, the initial data acquisition frequency is 100Hz, and the first-level anomaly matching threshold of the security anomaly warning set is 80%.

[0035] Dynamic adjustment of communication parameters

[0036] When the wind turbine is running, the communication parameter acquisition and analysis module detects that the signal strength is continuously lower than -90dBm and the bit error rate rises to 5×10 -5 , exceeding the set threshold. After processing the collected data, the centralized analysis unit sends a signal of communication quality degradation to the IPC hardware platform.

[0037] After receiving the signal, the IPC hardware platform immediately analyzed the cause and determined it was signal interference. It then sent an adjustment command to the communication parameter acquisition and analysis module, switching the communication channel from the current channel to the backup channel and increasing the transmit power by 2dB.

[0038] After the adjustment, the communication parameter acquisition and analysis module monitors the communication parameters in real time, and the signal strength returns to -80dBm, and the bit error rate drops to 5×10 -7 , communication returns to normal and the results are fed back to the IPC hardware platform.

[0039] Run data processing optimization

[0040] Under gusty conditions, the wind turbine speed increased from 12 rpm to 18 rpm within 10 seconds, a rate of change of 0.6 rpm / s, exceeding the set threshold of 0.5 rpm / s. The parameter acquisition and analysis module in the operational data processing process detected this and automatically increased the data collection frequency from 100 Hz to 200 Hz.

[0041] At the same time, the module detected an increasing trend in data transmission latency, reaching 45ms, approaching the 50ms threshold. To prevent further increases in latency, the module activated the data compression algorithm and adjusted the data compression ratio to 3:1.

[0042] After adjustment, data acquisition can accurately capture the details of speed changes, and the data transmission delay is stable within 40ms, ensuring the timely processing and transmission of operating data and providing a guarantee for the precise control of the unit.

[0043] Security exception handling

[0044] When the gearbox temperature of a wind turbine rises from 60°C to 90°C within 5 minutes, and the generator power fluctuation exceeds ±10%, the safety abnormality warning set matching and execution module receives these data and conducts a comprehensive analysis.

[0045] By matching the alarm with the safety anomaly warning set, the module determined that the match degree associated with gearbox overheating was 90%, exceeding the first-level anomaly matching threshold. The module identified this as a second-level safety anomaly, immediately sounding an audible and visual alarm and sending an anomaly signal to the IPC hardware platform.

[0046] After receiving the signal, the IPC hardware platform sends instructions to the parameter acquisition and analysis module for the operational data processing process, increasing the acquisition frequency of gearbox temperature and generator power to 500Hz to more accurately monitor parameter changes. Simultaneously, it sends instructions to the actuator to adjust the blade angle, reduce the unit speed, and reduce the gearbox load.

[0047] After treatment, the gearbox temperature gradually dropped, the generator power tended to stabilize, the safety anomaly was resolved, and the system returned to normal operation.

[0048] Through the above-mentioned implementation, the present invention realizes the dynamic adjustment of communication parameters of wind turbines, optimization of operation data processing, and accurate processing of safety anomalies, effectively improving the operation performance and safety of wind turbines, and has broad application prospects.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
