Given that the noise and other issues, the wind generator located on the ground is difficult, therefore the establishment of the Ministry of Environment to consider the sea, would also help to reduce carbon dioxide emissions. Compared to the fixed placement in the sea wind power generator implantation, floating style wind turbines can be installed in waters deeper than 50 meters. Power generation capacity is expected to reach 2,000 kilowatts.

It is reported that the Ministry of Environment will invest 2 billion yen (about 140 million yuan) from 2012 to 2014 to the end of the building floating wind turbine style experiments, and to investigate the generation or transmission of the performance, durability, on marine life and so on.

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.

According to the Danish consulting firm BTM, although the Danish Vestas and General Electric is still dominated by the global wind turbine supplier in the first two top spot, but Chinese companies are catching up.

Sinovel China Technology Co., Ltd., Xinjiang Gold Wind Technology Co., Ltd. and Dongfang Electric Group Co., Ltd. are among the world’s top ten industries, while Chinese companies are competitive export market.

HSBC renewable energy, resources and energy project director RobertTodd said: “The (Chinese manufacturers) has established an international sales team is actively bid for overseas contracts. Their real progress is only a matter of time.”

Goldwind Monday said its in Chicago set up a wholly owned U.S. subsidiary, announced Goldwind to the market dominated by General Electric launched its attack. Goldwind previously set up production bases in Germany, last year set up a subsidiary in Australia.

Sinovel is China’s largest wind power generator equipment company, ranked third in the world. The company exports to India last year, 10 sets of 1.5 MW wind turbine, also in March the company purchased from American Superconductor electrical system for its self-developed 5-megawatt wind turbine use. Company plans to export such future large-capacity wind turbine.

In the solar power market, the price of Chinese products than similar products in Europe or the United States is much lower. Some people worry that this could depress prices of wind turbines, solar power market, leading to oversupply, repeat last year’s mistakes.

Export potential

Often people complain that the Chinese domestic market, blocking, or by providing huge subsidies and cheap loans way to help its exporters an unfair competition.

German solar company Conergy and Solarworld have told the Chinese solar panel small wind turbines manufacturers expressed strong concern about the pricing behavior.

But at least for now, the Chinese wind turbine manufacturers are still the focus of the domestic market, the pace of these companies overseas is not for many international companies have too much of a threat, especially considering the logistics required to transport these massive costs.

Siemens spokesman said: “The Chinese small wind generators manufacturers began to visit the overseas market, such as in India or the Asia Pacific region. But still the focus of Chinese domestic enterprises.”

China is the world’s largest wind energy market in 2009 to increase its wind power generators capacity of 1.3 megawatts or more, than the original doubled.

China’s domestic manufacturers of wind turbines now occupy 80% of the market, and in less than a decade ago, Vestas, GE and Gamesa and other foreign companies are major players in the Chinese market.

Because induction generator absorbs reactive power from the grid to make wind turbine power factor reduced, and net operating wind turbines generally require the power factor above 0.99, it is necessary to use capacitors for reactive power compensation . Due to random changes in wind speed, rated power is reached before the size of the generator output power of random variation, and therefore compensate for the capacitance of the input and removal of the need for automatic control, by a computer according to the changes in the output reactive power, control, compensation capacitor or the removal of sub-investment to ensure that power factor meet the requirements. For the doubly-fed generator is directly controlled by the control system and regulation of reactive power.

Yaw control and automatic Jie Lan

① Automatic Wind

Normal operation automatically when the yaw control system for wind, that is, when the cabin the wind direction deviated from a certain angle, the control system to the left or right to issue instructions to the transfer, the cabin began to wind, When you reach the allowable error range, automatically wind turbines

② Auto-Jie Lan

When the cabin in the same direction after the cumulative circle deflected 2.3, if the wind speed is less than the wind turbine at this time to start wind speed and no power output, then the shutdown, the control system makes the cabin in the opposite direction around the rotating solution of 2.3 ring; if the unit has power output at this time, automatic solution is temporarily bypass; if the cabin to continue to deflect the same direction, accumulated over three laps, then control the shutdown, solutions around; Ruo Yin Fault Auto Solutions is not around the success of the twisted rope of 4 laps, twisted rope mechanical switch will move , this time twisting cable fault reporting, automatic shutdown; to wait for manual Jielan operation.

③ Wind Wheel Protection

When there are big strong winds occur, downtime and the release of tip-damping plate, transferred to the greatest pitch, yaw 90 degrees leeward in order to protect the wind generators wheel against damage.

Shutdown Control

When the controller issued a normal shutdown command, the wind turbine will be shut down the following procedures: ① removal compensation capacitor; ② release tip sheet damping; ③ generator off-grid; ④ generator speed measurements down to set the value, the input mechanical brakes; ⑤ In case of car trouble while Lee received paddle in the cabin, such as 90 degrees yaw leeward.

When an emergency shutdown fails, the implementation of such as non-stop operation: First, removal of compensation capacitors, tip-damping plate movements, delay 0.3 seconds after the caliper brake action. Detection of instantaneous power is negative or less than the synchronous speed when the generator to convey; generator solution column (off-grid), if the braking time of more than 20 seconds, speed has not dropped a set value, then the closed paddle, cabin yaw 90 degree leeward.

Magnetic levitation is an extremely efficient system for wind energy. Here’s how it works: the vertically oriented blades of the wind turbine are suspended in the air above the base of the machine, replacing the need for ball bearings. The turbine uses “full-permanent” magnets, not electromagnets — therefore, it does not require electricty to run. The full-permanent magnet system employs neodymium (”rare earth”) magnets and there is no energy loss through friction. This also helps reduce maintenance costs and increases the lifespan of the generator.

Maglev wind turbines have several advantages over conventional wind turbines. For instance, they’re able to use winds with starting speeds as low as 1.5 meters per second (m/s). Also, they could operate in winds exceeding 40 m/s. Currently, the largest conventional wind turbines in the world produce only five megawatts of power. However, one large maglev wind turbine could generate one gigawatt of clean power, enough to supply energy to 750,000 homes. It would also increase generation capacity by 20% over conventional wind turbines and decrease operational costs by 50%. If that isn’t enough, the maglev wind turbines will be operational for about 500 years!

Construction began on the world’s largest production site for maglev wind turbines in central China on November 5, 2007. Zhongke Hengyuan Energy Technology has invested 400 million yuan in building this facility, which will produce maglev wind turbines with capacities ranging from 400 to 5,000 Watts. In the US, Arizona-based MagLev Wind Turbine Technologies will be manufacturing these turbines. Headed by long-time renewable energy researcher Ed Mazur, the company claims that it will be able to deliver clean power for less than one cent per kilowatt hour with this new technology. It also points out that building a single giant maglev wind turbine would reduce construction and maintenance costs and require much less land than hundreds of conventional turbines. The estimated cost of building this colossal structure is $53 million.

Upset Guildwood residents, along with sympathetic protesters across Ontario, gathered outside the Miller Lash House at the University of Toronto Scarborough Campus on Tuesday, Aug. 11, eager to vent their discontent to Premier Dalton McGuinty over a proposed wind farm.

There was a great deal of resentment for McGuinty’s Green Energy Act, which protesters viewed as removing their rights to have input into projects planned in their neighbourhoods — specifically, the possibility that 60 wind turbines could be erected off the shore of the Bluffs.

Residents began expressing their opposition a year ago to a decision by Toronto Hydro to place an anemometer in Lake Ontario to test the viability of a wind farm. The testing would take about two years and if it proves successful the wind farm could go ahead.

Many of the approximately 40 people at this week’s protest said they felt insulted by McGuinty’s February speech in which he referenced Bluffs residents and vowed not to let NIMBYism stand in the way of renewable energy projects.

In Scarborough for the first time since making the comments, McGuinty was scheduled to attend a private barbecue for Liberal MPPs at 6 p.m., but angry Bluffs residents had already congregated an hour beforehand.

“We are here to send a warning. The premier is here to get his members revved up for the 2011 election and we’re here to tell him that we’re revved up too,” said John Laforet, president of Wind Concerns Ontario, a coalition of grassroots organizations from across the province.

Shortly before the political gathering was to begin, however, Ontario Provincial Police officers arrived and asked all protesters to leave the university property or risk being arrested.

As a result, the group headed to Old Kingston Road. After speaking with OPP officers, Laforet called on the Toronto Police officers stationed at the university hoping they would defend the protest. But the protesters were told to move off the site while the university administration assessed the safety of the situation.

On Old Kingston Road, the protesters continued to wave banners and chant “Protect the environment, no turbines in the lake” as passing motorists honked their horns.

At 6 p.m. the police officers once again approached Laforet and took him aside.

“The fact of the matter is that this is a private event and where that extended to is the issue of debate here,” said one of the officers. “That has been resolved and you are welcome back on the site, but the actual facility that they are using is out of bounds.”

With Laforet and others at the main entrance, half of the group walked back to the property. Nobody had yet seen McGuinty, but when Scarborough Southwest MPP Lorenzo Berardinetti arrived at the barbecue he stopped to speak.

“You need to stand up for Scarborough! We need your voice,” shouted one angry protester.

“I’m going to pass these concerns along to the premier and we’ll see what he says,” said Berardinetti in response.

Rapid-fire questions were shot back, shouting over Berardinetti’s voice.

Berardinetti brushed off a party official trying to bring him inside, responding, “This is more important.”

Berardinetti, before he left to join his party members, assured the protestors he would speak with the premier. He was handed an envelope containing information prepared by the protesters and Berardinetti confirmed the next day he’d personally delivered it to McGuinty.

Laforet returned to the Miller Lash House and explained that McGuinty had entered through the back of the building. By 7:10 p.m. the crowd began to dissolve. Laforet declared the evening a success and decided to call it a night.

Reached the day after the protest, Berardinetti urged patience.

“Residents do come first and I’m their voice at Queen’s Park,” he said. “Their concerns become my concerns, but remember that I don’t always get my way, either. I can be just as angry as those protesters, but that doesn’t mean that the cabinet ministers or the premier will agree with me.”
