1.5MW series wind power generation
The SL1500 series wind turbine adopts mature and reliable doubly fed power generation technology, with an impeller diameter of 70/77/82/90/93m and a hub height of 65/70/80/100m, which can meet the installation needs of various onshore areas. Since the establishment of China's first megawatt level wind farm in 2006, a total of over 8543 units have been installed. The unit has been certified by authoritative domestic and foreign certification agencies such as GL, TUV South Germany, and China Jianheng. After years of continuous optimization and upgrading, a new third-generation wind turbine has been launched.
Technological Superiority
Based on the operation big data analysis of more than 8000 wind turbine units on site, system optimization and upgrading have been carried out on key components, electronic control systems, remote monitoring, and other aspects to improve the performance and operational reliability of the units and increase the power generation of the wind farm;
By adopting advanced technologies such as load optimization control, fault self diagnosis and warning, wind turbine information sharing, program intelligent upgrading, and wind turbine debugging and defect elimination intelligent platform, the reliability of the unit is improved and the maximum utilization of the unit is achieved;
Introducing intelligent control technologies such as dynamic fine pitch and yaw control, soft cutting, and grid optimization, to deeply tap into the potential of unit power generation, increase power generation, and achieve maximum user benefits;
Providing wind farm power prediction systems, advanced technologies such as security systems, noise control, and refined on-site data management systems, fully meet the personalized needs of users;
Meet the strictest grid guidelines at home and abroad, intelligently regulate the active and reactive power output of units, and achieve international advanced level in high and low voltage crossing and grid adaptability.
FEATURES
●Variable pitch system
The backup power supply uses supercapacitors to ensure the safe shutdown of the unit in the event of a power outage in the grid;
The pitch motor and control cabinet are installed inside the wheel hub, with good lightning protection and sealing effects.
●Gearbox
The spindle is built into the gearbox, with a compact structure that does not require on-site alignment;
The main bearing has good lubrication effect and long service life;
Each transmission stage is equipped with observation holes for easy maintenance;
Rear mounted slip ring improves the stability of slip ring operation.
●Vibration reduction system
Two layers of vibration reduction blocks are installed at the connection between the gearbox and the main frame for vibration reduction and noise reduction of the gearbox.
Oil cooling system
The air duct of the oil cooled radiator is for external air intake, which improves the heat dissipation effect of the radiator and avoids contamination of the heat dissipation plate by the oil and gas emitted from the gearbox.
●Ventilation system
The rear of the cabin is ventilated by an axial flow fan, effectively reducing the temperature inside the cabin.
●Generator
Efficient water-cooled generator with small size;
Adopting insulation end caps and multi-point grounding technologies to eliminate the influence of shaft current;
The cooling system adopts natural air cooling, which consumes less power, produces less noise, requires less maintenance, and has strong wind and sand resistance.
●Yaw system
The yaw system adopts sliding pad support with self-lubricating function, without the need for additional lubrication system and yaw brake.
●Cabin sealing
The front of the engine hood is equipped with a partition wall to prevent wind, sand, and rainwater from flowing into the engine compartment from the front.
●Down placement of frequency converter
The frequency converter is located at the tower base and uses air cooling for reliable operation.
