The power coming from the generator goes to a converter where the power frequency get converted to match the grid 60HZ. Insulated gate bipolar transistors and capacitors are used to achieve this. The power goes from the generator, converter, transformer, grid.

@@chrisanderson6538 This is true for small turbines in the 10s or 100s of kW. In the MW range it is almost always done by doubly fed induction generators because the converter doesn't have to pass the whole power but only a small amount to feed the rotor. This is usually in the order of the difference between the mains frequency and the rotors rotational frequency. So if you plan to have 100MW and +-10% deviation in speed, you need a 10MW converter instead of an 100MW one

Great explanation of doubly fed induction wind turbines. These are referred to as type 3 wind turbines. Another method like the one used in your small scale wind turbine is too rectify and invert the variable frequency power from an induction or permeant magnet generator to the grid frequency. This is what the newer type 4 wind turbines do but they require higher capacity power electronics to do this because they are converting 100% of the wind power as opposed to only a small proportion that is being back fed into the doubly fed induction machine like in a type 3 wind turbine. The reduced cost of power electronics and lack of brushes and gears however is making type 4 more popular.

17:17 this electrical load can also be used to vary the power output and breaking of the wind turbine as opposed to mechanical and aerodynamic breaks. Allot of smaller wind turbines use a maximum power point tracking algorithm via the the voltage on the inverter to vary the current and hence torque of the generator which can control the rotation and power output of the turbine. Small scale wind turbines can also use large variable resistors as dump loads but this is less efficient.

Yes your assumption is correct. There are many different methods used. For example in offshore power production the AC current can be converted into DC for transportation through the ocean. A nother method is to convert AC into DC and then back to DC with exactly 50Hz. Power electronics are quiet efficient so conversion losses are not that high.

@@egoinjury in conventional machines, you can imagine a magnet with north and south poles rotating with the prime mover (i.e. a gas turbine). So the frequency of the generator is directly proportional to the speed of the shaft. In wind turbines, imagine that the same magnet is able to rotate at a different speed than the shaft, so when the shaft is slow, the magnet will rotate to compensate for the generator to match the grid frequency (50 or 60 Hz).

Speaking in general terms (it can get complicated on the micro level... so I'll stick to Macro) power produced by the generator is run through a "rectifier" (actualy an IGBT module) where the dirty AC is turned into DC. Its stored on a large capacitor bank then inverted into 60Hz by another IGBT module before leaving the turbine. The controlling circuitry has a grid moniter that watches the grid and tells the turbines IGBT module when to fire so it matches the grid. Dirty AC ----> Smooth DC ----> Clean 60Hz AC ready for use on the grid.

00:00 🌬 Introduction to Wind Turbine Basics Wind turbines convert wind energy into electricity. Factors influencing power generation include wind speed, turbine size, and blade design. Turbines can be located on land or at sea, each with its advantages and challenges. 02:01 🏗 Wind Turbine Structure and Design Large turbines consist of a tall tower, generator, gearbox, and rotating blades. The tower houses essential components like the generator, gearbox, and braking system. Blades, made of reinforced glass fiber, capture wind energy with optimal aerodynamics. 05:02 🔄 Wind Turbine Operation Process Wind direction and speed are monitored by a wind vane and anemometer. The turbine adjusts its position to face the wind for optimal energy capture. The rotating blades generate mechanical energy, converted into electrical energy by the generator. 09:12 🔄 Blade Angle and Power Generation Blade angle affects lift and drag, crucial for controlling turbine speed. Optimal blade angle maximizes power generation without overheating the generator. Wind turbines have cut-in and cutout speeds for safe and efficient operation. 10:47 🔄 Number of Blades and Energy Production The number of blades influences stability, voltage production, and ease of rotation. Three, four, or five blades are common for optimal energy production. Blade design and number vary based on turbine size and application. 14:10 ⚙ Gearbox and Generator in Wind Turbines Large turbines use a gearbox to increase generator speed for efficient electricity production. Doubly Fed Induction Generator (DFIG) is a common generator type for large wind turbines. Gearbox, hydraulic brake, and generator work together to ensure controlled and stable operation. 17:17 🔄 Electricity Generation and Frequency Control DFIG uses rotor speed control to match generator frequency with grid requirements. Controller adjusts rotor speed to maintain a constant 50 or 60 Hz output. Wind turbine operation explained in the context of frequency control and electricity generation. 20:26 🎓 Sponsor Message: Brilliant Learning Platform A brief message about the Brilliant learning platform and its relevance to engineering education.

Slip ring on the gearbox that feeds all the control wiring to the hub. Pitch motors have battery for backup.

I used to live on a hill that had a small/medium sized test wind turbine on it. This was 30 odd years ago. Don’t remember ever hearing it unless you went up to the top of the hill. Also sadly isn’t not always Sunny or windy. Sometimes it can be neither. Hence why we need ways to store energy too.

Cool! I am not familiar with the gearbox system. The systems I am familiar with have no gearbox and instead use a very large generator. Then it converts the generated power to DC and then concerts the DC back to AC to get a nice consistant sinewave.

I never knew you could change the frequency of the output of a generator by changing the frequency of the powered stator. I though the stator was always a permanent magnet, but it now makes sense why it’s powered, cause permanent magnets cannot get any more powerful, and you cannot induce a variable rotating magnetic field in them, that’s such excellent engineering. I always thought a wind turbine would require a bulky external circuit that converts the variable frequency AC to DC and then back to the precise 60 Hz AC. Excellent. But, let’s say we have these wind turbines in a secluded place where the power consumption is very little, then converting to DC and then transmitting DC would be far more efficient than AC. There would be losses at the conversion plant that converts the DC back to AC, but in this situation, the overall efficiency of the entire system would be much higher than transmitting AC.

I love and work on a wind farm and I think they look beautiful and they are not very loud. Living next to an airport, train track, or even highway is much worse. Also the blades normally last the life of a wind turbine so for people worried about disposal the amount of trash from 1 person over 30 years would take more space than 1 blade. There isn’t 7 billion wind turbines. A better way to cut down on land fill space is for individuals to recycle, compost, and reduce their carbon foot prints.

Not only would I live near wind turbines, but I have one attached to my home with plans to attach three more in the coming years. Add that to my solar array, also attached to my home, and I have enough power to be completely off-grid for everything but my largest shop tools. For them, I have a pair of 6.5kw generators. I believe every new home should be built with renewable energy designed into the home. The solution to the energy problem is for every household to generate as much of their own power as possible, using the grid only for the highest loads like shop equipment and large appliances.

My dream, and probably many peoples, is it be completely self sustaining. Generate my own energy as priority (no bills!), glad to hear you're heading down that route. The problem with wind turbines attached to buildings is the vibrations can cause structural damage so do be mindful of that if attaching it to your home. Better to have it's own support structure.

@EngineeringMindset I hear you.... but it's been there for 5 years now. Spun clear up to the governor and stayed there for a little under 6 hours one night. Hit dynamic braking twice.... THAT was noisy!!!! No damage. I seriously overbuilt the mounting, I think... I actually enjoy the sound of it. Whistling screaming shriek with the blade tips doing 300mph, at which point they start aeroelastic twisting as another means of controlling rotor speed. That's a WICKED fluttering whooshing sound... THAT gets some vibration, but again... I went a bit overboard building the tower and roof mounting system. I love wind and wind power. I'm looking forward to moving to Montana next year. LOTS more wind over thataway.

There is common misconception asserted in this video. Wind turbines are more often than not constructed as a synchronous generator and not a primary supply generator. That is, they contribute to the capacity of the grid only (how many Amps the grid can supply) and still require the grid to have a base load power supply. The comparison between between a wind turbine and simple DC motor is good for understanding the theory, however it doesn't translate into reality and only leads to people believing that you only need wind turbines. Now, all this is not to say that you can't have a power generating wind turbines, but they are generally not made that because of the sheer size that would be required for such scaled application. So instead, they scale them down to be synchronous generators and contribute to maintain the overall capacity of the grid. On the whole though, really great video!
