01、Hydraulic pitch for wind power generation: the guardian angel in typhoons
In the furious typhoon season, the safety and stability of wind power equipment is crucial. In many wind power pitch technology, hydraulic pitch with its excellent performance and reliability, has become the guardian of the typhoon weather. Today, we will analyze in detail the advantages of hydraulic pitch in the process of anti-typhoon.
1. Low failure rate, stability and reliability of hydraulic pitch for wind power generation
In extreme weather conditions such as typhoons, wind power equipment needs to withstand a huge test. The hydraulic pitch system provides a solid backing for wind power equipment with its low failure rate and high stability. Even in typhoons or other emergency failures, the hydraulic pitch can ensure a smooth smooth pitch action, effectively avoiding safety accidents caused by pitch failure.
2. Wind power generation hydraulic pitch with high output and quick response
When a typhoon strikes suddenly, wind power equipment needs to respond quickly to protect its own safety. The hydraulic pitch system, with its powerful output and excellent response characteristics, can send out a huge amount of energy in a very short time to ensure that the paddle blades under heavy loads successfully complete the protection action of retracting the paddle, effectively avoiding the occurrence of overspeed accidents.
3. Hydraulic wind turbine propeller does not need backup power, safe and worry-free.
In typhoon weather, the power supply may be seriously affected. However, the hydraulic pitch system does not need to rely on backup power for pitch operation. It relies on accumulators to push the hydraulic cylinders for pitching, ensuring safe operation in the event of a power loss. Accumulators offer better safety, reliability and longevity than batteries or supercapacitors.
4. Wind turbine hydraulic pitch cushioning, reduce loads
Hydraulic pitch system has good buffer by pushing the blade through the hydraulic chamber for pitch operation. In case of sudden shutdown, it can greatly reduce the load of the whole machine, effectively avoiding the excessive load of the whole unit in case of typhoon or other emergencies, so as to protect the tower and blades from damage.
5. Hydraulic pitch self-locking mechanism for wind power generation, preventing overspeed
The hydraulic pitch system is equipped with a blade bearing self-locking mechanism (hydromechanical lock), an innovative design that plays a great role in case of emergency failure or typhoon. It ensures that the blades can only turn in the downwind direction and can be locked in the downwind position. In this way, even the strongest typhoons cannot blow the locked blades back into the windward position, thus avoiding wind turbine overspeed problems.
In conclusion, the hydraulic pitch system has demonstrated five major advantages with its excellent performance and reliability in the typhoon resistance process. It not only ensures the safe and stable operation of wind power equipment, but also greatly reduces the failure rate and maintenance costs. In the future development of wind power, the hydraulic pitch system will continue to play its important role in bringing safer, more efficient and reliable technical support for the wind power industry.
02, wind power generation hydraulic pitch for future advantages of high-power units
Hydraulic pitch system for future high-power unit has many significant advantages, these advantages make it in the field of wind power generation has a wide range of application prospects.
Wind power generation hydraulic pitch cylinder synchronization is excellent, balanced power without risk
Most of the high-power units use dual hydraulic cylinders to drive a blade, hydraulic pitch system because of its uniqueness, in the wind turbine generator set to show its excellent cylinder synchronization, and effectively avoid the problem of uneven output of hydraulic cylinders.
Wind power generation hydraulic pitch expansion is simple
When it is necessary to increase the capacity of the wind turbine or to adapt to larger sizes of turbine blades, the hydraulic pitch system can be expanded by increasing the number of motors and accumulators as well as by increasing the stroke of the cylinders, while the cost increase is relatively small.
Piston Accumulators for Wind Turbine Hydraulic Pitch, Emergency Pitching without Worries
Piston accumulator to realize emergency propeller, there is no backup power failure can not be propeller problems. Piston accumulator design structure is simple and easy to maintain. Its work is stable and reliable, with long service life and low maintenance cost.
Millisecond response for wind power hydraulic pitch, independent pitch, cost reduction
The millisecond response time to perform the pitch, more adaptable to independent pitch, reduce the cost of the whole machine.
Wind turbine hydraulic pitch independent pitch ("IPC" for short)
Independent Pitch Control ("IPC") is a wind turbine pitch technology that allows different pitch commands to be issued according to the actual load of each blade, controlling the change of pitch angle so that each blade can obtain a different target position. This technology helps to reduce the unbalanced fatigue loads on the impeller faces, thereby regulating the wind turbine speed and wind turbine power output and improving overall efficiency and reliability.
Advantages of wind turbine hydraulic pitch independent pitch control technology include:
Optimization of turbine structure: By independently controlling the pitch angle of each blade, the fatigue loads on the various components of the turbine can be reduced, helping the wind turbine to achieve a lighter, larger and more flexible structural design.
Improvement of wind energy utilization: In low wind speed areas, WTGs with lightweight design can improve the efficiency of wind energy utilization in low wind speed areas.
Improve the operating life of wind turbine: improve the loading condition of each component of wind turbine, reduce the operation and maintenance cost of wind turbine.
Advantages of wind turbine hydraulic pitch hydraulic pitch for IPC conditions
Compared with the traditional unified pitch system, the adjustment frequency of independent pitch is higher, and the response speed and accuracy of the system are also more demanding.
Since the independent pitch system needs to adjust the pitch angle frequently, the pitch bearings are subjected to higher loads and friction, which may lead to easier wear of the teeth of the pitch bearings (electric pitch).
A clearance-free fit between the hydraulic cylinder ends and the drive shaft is required, which reduces friction and vibration and improves system reliability and life.
These advantages make the hydraulic pitch system an ideal choice for high-power units, helping to drive the continued development and advancement of wind power technology.
