      Thank you for this excellent article over viewing the different methods of generation and connection. I found the information on Synchronous Generators especially helpful. I added this article to my bookmarks. I am an inventor and work designing Mega Watt windmills

    2. jagadeesh jagadeesh says:

      how is generator rotor speed is maintained constant when wind speed is changing which changes rotor speed of wind turbine which in turn changes the rotor speed of the generator

    3. jagadeesh jagadeesh says:

      when wind speed changes wind turbine rotational speed changes which in turn changes the rpm of the generator rotor.But how you are telling that rpm of generator is fixed and wont change.

      • Synchronous Generators are “synchronised” (hence their name) with the mains supply before connection. During the start-up or low wind speed, the rotor speed and therefore the stator frequency is different from the mains supply frequency. Therefore a synchronous generator needs to be synchronised first using an external DC current to excite the rotor field as explained in the tutorial. Asynchronous electrical machines do not require any such synchronisation process.

      Sir . What is beetween difference pmg and emg

    6. Salah Salah says:

      Can we connect the fluctuating AC input of wind turbine synchronous generator to AVR for voltage regulation .??? Some of these AVR gives constant 220 V with the input goes down to 90 V ???

      • An Automatic Voltage Regulator, or AVR, takes a fluctuating voltage input and turns it into a constant voltage output, so it could, in theory, be used with a wind turbine generator. But there are many types of AVR’s so please consult the manufacturers datasheet first.

      Could we connect PMSG with diode rectifier and only capacitor in dc link ..then inverter to the grid…without chopper or any power electronic in dc link??
      I didn’t find any topology like that in research papers.

    8. Salah Salah says:

      Hi guys:
      If we can make power converter to get dc by using diodes as bridge rectifier, can we use diodes to make power inverter?? If that is possible,please releated diagram??

    9. Salah Salah says:

      Hi guys:
      Can we hook up the power inverter directly to the bridge rectifier outlet (and a smoothing capacitor in between if possible) to get ac power outlet..? In any of the wind turbine systems???
      Thank you

      I am trying to find out how much the actual rotor or generator ways that produces 1.5 – 2 MW of power.

        Sir I want 1500watt 24v to 40v brush less wind turbine generator. This type of motor i want to e-bike. If you have this type of motor, give me information and details.

      I am looking for a genhead for making a tidal stream generator 10kw: any suggestion ..please.

    12. pkhanh pkhanh says:

      So what really is the advantages of using synchronous generators for wind power systems, in both family scale and medium size scale ?

    13. Binu Binu says:

      Will the harmonics due to uncontrolled rectifier circuit affect the permanent magnet?

    14. Lucas Gonzales Lucas Gonzales says:

      In the top 10 of my favorite articles, thanks!

    15. Ken Ken says:

      So does this PSMG required a gearbox?
      Not clear about that

      • Hi Ken, It really depends on the type of permanent magnet synchronous generator you have and the speed at which it needs to rotate. The low rotational speed of the wind turbines rotor blades can be increased through the use of a gearbox which will allow the generator speed to remain more constant, but the downside is that a gearbox will reduce efficiency as extra wind energy is required to drive the gearboxes cogs.
