I. Functional Characteristics of Variable Pitch Wind Turbines
1.1 Advantages of Variable Pitch Technology
The pitch wind turbine produced by our factory: it is the optimal choice of pitch system for all wind turbine generators at present, the pitch system utilizes the generator's own power value to change the blade angle, the impeller in the operation process, if the generator reaches the rated power, the pitch system is influenced by the generator's own power, it will change the pitch angle linearly in real time, so that the generator output power is stable in the rated range. The pitch mechanical structure and control that is simple and reasonable, original pitch technology will greatly reduce the equipment failure rate.
1.2 System Advantages
Variable Pitch Control Series Wind Turbine Advantages:
(1)The use of direct-drive permanent magnet generator, high-efficiency rare earth materials, the shell is made of carbon steel.
(2)The wind wheel structure is simple, the hub adopts the mature variable pitch structure, no complex moving mechanical devices, the failure rate is extremely low.
(3)The use of six high-end transmission slip ring conductive, no twisted cable phenomenon.
(4)The rotor vertical axis without rigid drive mechanism, only the use of conventional bearings, this structure can be due to unstable airflow brought about by the jitter and vibration easily dissolved, conducive to improving the life of the wind turbine.
(5)Generator efficiency of more than 90%, wind energy utilization factor of 42%.
(6)Unique simple control method, automatic wind, effectively improve the efficiency of the wind generator; make full use of the permanent magnet generator to do its own torque to control the blade pitch, to achieve the best state of power generation, annual power generation increased by more than 30%.
(7)With automatic electromagnetic unloading function.
(8)Using a unique sealing structure, it is completely moisture-proof and dust-proof.
II. The System Composition
Wind turbine models off-grid for off-grid power supply, usually used in small villages, islands, marine platforms, posts, border defense, pastoral areas, mobile base stations, independent households, monitoring power supply, farms with electricity and other needs. Due to the influence of wind resources, the off-grid system can also be composed of wind and solar panels and wind-solar complementary power generation system.
Used for grid-connected power generation generally use more than 2KW type wind turbine generator, can also be matched with photovoltaic, forming a wind-scenery complementary grid-connected system.
Off-grid or grid-connected generator sets, conventionally equipped with controllers, inverters are the same power specifications. It can also be equipped with controllers and inverters larger than its own rated power.
