Hangzhou wind turbine test run

A high iron, the above three long pointed leaves turn in the breeze, when will "shake their heads" looking for the biggestwind  generators direction, high-speed rotating blades to produce electricity, this is a wind turbine shape description.

    Wind power generation equipment in general such as films appear in the open sea, endless desert, or the high peak.

    Yesterday, however, there are enthusiastic people found Hangzhou Center, there have been wind turbines, but also on the elevated side of the pond.

    How many cities wind power can be issued? A large wind generators will not be down? With a number of questions, the reporter went to the scene take a closer look.

    Roof of the wind turbine, so what's special

    On the installation of wind turbines in Zhejiang Electric Power Test & Research Institute one of the eight floor building roof, it has a resounding name of the first, "low-carbon economy and demonstration project in Hangzhou."

    At present, only two wind turbines, 3 days ago and the grid, maybe your home TV is the wind power start yo.

    Project Leader Dr. Zhao Bo said that the two wind turbines of the iron only 6 meters high, relative to the wild dwarf number of wind turbines.

    "Because they stand on the shoulders of giants. Ah giant that is this building, there is the height of the building to do the base. If on the ground, the generator iron would be 12 meters to 18 meters high."

    In the wind turbine side, also installed a small weather station to record real-time wind speed, wind direction.

    Wind of the fan turn faster, will not have the noise

    wind Generators are 6 meters in diameter, in the wind too large, the fan will spin into a circle, fast too visible.

    Shentou looked at the Provincial Electric Power Test & Research Institute there are residential buildings in the vicinity, will not produce noise, quarreling, to nearby residents?

    Dr Chiu smiled: "Of course there is no noise 啦. If there is noise, certainly there will be complaints from residents of phone calls to you first hit the media has."

    Reporter under the wind turbine stood for a moment, it really sounds very light, just as much a fan head, only hear the buzzing of the wind.

    High spirit out of electricity, can be available for how many people use

    Dr Chiu said that as long as the wind speed is greater than 3 meters per second (2 wind, breeze, often feel the wind), wind turbines on the roof started. When the wind speed over 4 meters per second (wind 3, breeze, when the wind allows flags started), wind turbines can transfer energy to the grid.

    The weather, like yesterday, this is estimated to reach 2 kW power generation or so, which is equivalent for a family to open a 1.5 air-conditioning and a television, and then open Jizhan Deng.

    Of these two wind turbines, if the full-load power generation, power generation, power can reach 10 kW per day can supply about 20 people a day of normal power consumption.

    "But if you want to operate at full capacity, the wind speed of at least 11 meters per second or more, it has been the equivalent of six strong wind of." Dr Chiu said humorously, "windy days, we walked downstairs to the public really do not worry, we wind leaves a very strong, never will be blown down to. "

    Wind power could ever use, can save up and do

    The past few days, twowind power generation equipment in the end made a number of electricity?

    Dr Chiu said that because the whole system is only trial run, it is completed, we have to wait a month later, so the entire device in the end made a number of electricity, there is no record. "Wind energy is intermittent energy sources, that is dependent on weather conditions, when wind power is sufficient, no wind when the device is decoration."

    Of these two wind generators have been connected to the distributed power and micro-network laboratory storage system, not use up electricity can be stored together. "This is to to be able to vigorously promote new energy sources such as wind power, making it into the ordinary citizen's home." Dr Chiu said that the evening wind turbines are generally large, but everyone is sleeping, no electricity, fans issued electricity can be stored during the day when the need for electricity, a chance to use.

    Our roof, Shashi can also have "Little Fan"

    How long that ordinary people can also be erected upstairs family such as "Little Fan"?

    This, Dr Chiu not give an accurate answer.

    Because the package of equipment still in the experimental stage, along with the basis to build on the roof to be reinforced, the entire investment is relatively large.

    The ultimate goal of testing is to be able to spend thousands of families that want to clean energy. "This equipment, materials and technology are all homemade. So long as to achieve economies of scale, there is policy support, the cost will certainly be greatly reduced, to promote the speed will be faster." He said.

    "In addition, in the Riverside senior fitted with such a wind turbine, the effect certainly better than the city."

    Maybe someday, we have a roof with a Li-"Little Fan", we each have to use with such a "self-sufficiency" clean energy.
