The principle of wind power is driven by wind turbine blades rotate

admin — Sat, 21 Aug 2010 14:19:56 +0000

The principle of wind power generators is driven by wind turbine blades rotate, and then through the growth machine will improve the speed of rotation, to induce generators. According to the current of the windmill is about three meters per second wind speed (wind level), it can start generating electricity.
Wind power is the world form a boom for wind power without fuel problems, it does not produce radiation or air pollution.

Wind power in Finland, Denmark and other countries is very popular; western China is also strongly advocated. Efficient small-scale wind power generation systems, but it is not only by a generator of aircraft parts, but a certain scientific and technological content of small systems: wind turbine + Charger + digital inverter. Wind turbine by the nose, swivel, rear wing, leaf form. Each part of the very important functions of various parts: leaves used to receive through the nose into the wind power; tail so that leaves always opposite to the direction of the wind to get the most out of the wind; swivel head can rotate in order to achieve flexibility tail to adjust the direction of the function; head of the rotor is permanent magnet, the stator windings cutting magnetic lines to produce electricity.
Fluctuating wind power generation due to small wind turbines, so the output is 13 ~ 25V AC change, subject to the charger rectifier, battery charger store again, so that electricity generated by wind turbines into chemical energy. Then protect the inverter circuit, the battery inside the AC 220V chemical energy into electricity, can guarantee the stability of use.
Usually people think that wind power generator wind power solely by the decision, always wanted to buy a bigger wind turbine, which is not correct. The current to the battery charging wind turbines only, the energy stored by the battery up, people eventually use electric power, size and battery size have a closer relationship. Power depends on the size of even the size of wind, not just the size of the power head. On the mainland, a small wind turbine will be more appropriate than large. Because it is easier to drive and a small amount of wind power generation, continuous small wind, strong wind better than the moment a large supply of energy. When no wind when the wind it can also be caused by normal use of electricity, that is a 200W wind turbine can also be a large battery and inverter by co-use, access to 500W or 1000W and even more power out.
Use of wind generators, wind energy is pouring into our family used to the standard electricity, the savings level is obvious, a family only 20 yuan a year of electricity cost of battery fluid. Now the wind turbine generator performance than a few years ago a great improvement, previously used only in a few remote areas, wind generators connected directly to power a 15W light bulb, one out of a dark and often damage the bulb. And now because of technical progress, the use of advanced chargers, inverters, wind power generation as a certain scientific and technological content of the small systems, and can under certain conditions, instead of the normal electricity. Mountain to the system can not be a perennial money-lights; highway signs used it to do the night lights; mountain children can study up under fluorescent lights; urban high-rise roof, vertical wind turbine can also be used, which not only save but also real Green Power. Domestic wind generators, not only to prevent blackouts, but also increase the zest for life. In the tourism area, border, school, military and even behind the mountain, small wind turbine procurement is becoming a hot one. Radio enthusiasts could use their own technology in the wind power generation services for the mountain people, so that people watch television and lighting synchronized with the city, but also make their own enrichment work.

wind generator maintenance scheduling

admin — Sun, 15 Aug 2010 14:29:08 +0000

Fans were in operation, there will be some glitches have to go to the scene to deal with, so that we can look at the way for routine maintenance. First of all, carefully observe the safety of the fans are a solid platform and ladder, with or wind turbines without connecting bolts loose, the control cabinet or without paste flavor, whether the shift cable, plywood is loose, twisted rope pull ring is worn sensor break, yaw gear dry lubrication is bad, yaw gear box, hydraulic oil and gear box oil level is normal, the hydraulic pressure station meter is normal, between moving parts and rotating parts for worn out, look for any leaks in the pipe joints, gear oils and hydraulic oil filter instructions are in the normal location. The second is to listen, listen to whether the discharge control cabinet sound, a voice terminal may be a loose or poor contact to be carefully examined whether the sound when listening to normal deviation, whether dry grinding sound, listen to any abnormal sound generator bearings, gear box to listen to any abnormal sound, listen to brake disc and brake pad between any abnormal sound, listening to the sound leaves the wind shear is normal. Third, clean up their work site, and hydraulic station wipe all components and pipe joints in order to observe if there is leakage in the future.

To a good wind turbine operation and small wind turbines maintenance, but also to the fans in the normal conduct in-depth theoretical knowledge related to research and study, do a good job all maintenance records and archives, to conduct regular inventory of spare parts inventory, on multiple types of fans Failure to conduct thorough and meticulous analysis and seek to make its effective prevention. Only take preventive measures, is our highest state of operation and maintenance.

The role of wind turbine gearboxes

admin — Tue, 10 Aug 2010 02:15:05 +0000

Why use the gear box? Why we can not directly drive shaft wind generator?
If we use the common generators and use two, four or six electrodes directly connected to the three-phase 50 Hz AC power line, we will have to use speed to 1000-3000 rpm in the wind turbine. The 43 m rotor diameter wind turbine, which means the end of the rotor faster than twice the speed of sound is even higher. Another possibility is to build a alternator with a number of electrodes. But if you want to generator directly connected to the power line, you need to use electrodes of the wind generator 200 to obtain the speed of 30 revolutions per minute. Another problem is that the quality of rotor is proportional to the size and torque required. Therefore, direct driven generators will be very important. Use gear box, you can lower small wind turbine rotor speed, high torque, converted for use in generating the high speed, low torque. Wind turbine on the gear box, usually between the rotor and wind power generator speed single gear ratio. For the 600kW or 750kW machine, gear ratio of about 1 to 50.
