wind power: an inside look at how the turbine at exhibition place keeps spinning

Whether it is to love them or to hate them, wind turbines cannot be ignored;
The turbines at the Toronto Exhibition center are likely to be the most visible in Canada.
Owner of the tower-400-plus-
Member Limited
Agents and Toronto Hydro visited lakeside landmarks.
Like any tower, the turbine starts at the bottom and sinks into a 10-meter-deep rock bed.
The main shaft of the tower consists of three steel parts stacked on each other, up to 65 m and about 30 layers high.
The top of it is the \"cabin\", a steel section made of fiberglass with turbine blades connected to it.
The Cabin in the Ex to reach the turbine is an old-school journey.
According to the turbine operator, there are 198 \"vertical stairs from bottom to top.
An average English-speaking person would call them the 198 ladder.
The updated turbine has an elevator, but the building standard does not allow the elevator when the Ex turbine is built.
To transport the goods to the top of the tower, the turbine requires a lot of lubricant-there is a rope and pulley.
The climbers are tied to the safety rope on the ladder, and there are several platforms on the way up to stop and rest.
Standing on the platform, climbers can feel the vibration of the floor under their feet.
That\'s a good reason, says Co.
Gary Zavits, op member who led the tour.
The tower is designed to swing and vibrate to disperse the energy that would otherwise shake the electronics.
The cabin is located at the top of the steel tower and the entire assembly can be rotated.
The anemometer installed on the top measures the wind direction and speed.
It sends the information to the control system that activates the three motors.
The motor is connected to the gear and the gear turns the cabin so that the cabin is directly facing the wind.
These three blades are 24 m long per set and rotate 21 times per minute at the best speed.
This means that if you are standing at the top of the cabin, a blade will fly past your nose after about a second.
If you are facing the wind turbine, the blade will turn clockwise.
The small motor inside the tapered part of the blade directly connected can change the angle of the blade, so they always turn at the same speed.
It takes about 9 kilometers per hour to move the blade.
Anything over 71 kilometers per hour is considered too powerful;
In this case, the motor turns the blades at right angles to the wind so that they do not move.
The cone with the blade is surrounded by Donuts.
The shape of the device.
This is the business part of the turbine-the actual generator.
It has a range of strong magnets that rotate with turbine blades.
Fixed on the ring around the rotating magnet is a large number of conductive coils. As the electro-
The magnetic field generated by the magnet rotates in the wind, generating current, and the current is transmitted to the ground through the cable.
It was then sent to a nearby transformer station and sent to the regular grid. (
Turbine has a history of ten years now.
Newer turbines that produce three or four times the output typically use rotating blades to rotate the shaft of the gear assembly connected to the drive generator. )
This turbine generates enough power for 200 to 250 families.
The economy of this turbine has been bad.
Initially conceived as 750-
Kilowatt-class turbine with current capacity of 600 KWthird or one-

The Op\'s initial public offering (ipo) report estimates the company\'s annual output of 1,800 MW.
Actual production is less than 1,000 to 1,400 MW hours.
Since 2007, under a contract with the province, the owner has received a production payment of 11 cents per kWh.
