Principle of Operation of Wind Turbine

Yadda Turbin Kasa Yana Aiki?

Tuna da turbin kasa na daji-dajin sauran samun sararin gurbin da ya fi yawa. Idan kasa ta shiga abubuwa, turbin ya zama daidai saboda tsarin da ido mai sarrafa. Gindin turbin an sanya da makaranta masu harkar. Fadada makaranta an juye da kabelon kasa.

Idan kasa ta shiga abubuwa, abubuwan da suka faru. An sanya rotor turbin da gearbox mai harkar. Gearbox ya zama daidai saboda rotor rotor mai harkar zuwa harkar. Gindin gearbox mai harkar daidai an sanya da rotor makaranta kasa, saboda haka makaranta kasa ya zama da harkar daidai. Ana bukata exciter don bayar da tushen wani abubuwan makaranta kasa saboda zan iya bayar da kasa daidai. Fadada makaranta kasa (alternator) yana cikin fadada alternator ita ce mafi tsawo da kuma field flux. Harkar yana kan kasa kasa da ba a iya rarraba. Saboda haka don yanayi fadada kasa daidai daga alternator, ana bukata excitation a kan kasa. Fadada exciter an rarraba da controller turbin wanda ya sanar da harkar kasa. Daga baya, fadada makaranta kasa (alternator) an bayar da rectifier inda fadada alternator an juye da DC. Daga baya, fadada DC an bayar da unit converter line don juya da AC mai harkar daidai wanda ya bar da network transmission ko grid transmission da kyau da step up transformer. An yi wani unit don bayar da kasa na auxiliaries na biyu na turbin kasa (kamar motor, battery etc.), wannan shine Internal Supply Unit.
Ana da wasu mekanisomin kontrol da aka sanya da turbin kasa mai yawa.

• Kontrol kayan abubuwan turbin.

• Kontrol kayan mukar turbin.

Kayayi abubuwan turbin an rarraba daga hub na biyu. Abubuwan suke an sanya da hub na biyu da rike da gears da motor mai harkar ko hydraulic rotary system. System na ya zama electrical ko mechanical depending on its design. Abubuwan suke an swivel depending upon the speed of the wind. The technique is called pitch control. It provides the best possible orientation of the turbine blades along the direction of the wind to obtain optimized wind power.

Kayayi nacelle ko duk fuska turbin an yi don tabbatar da harkokin kasa don yanayi energy mechanical mai yawa. Harkokin kasa da kuma harkar ta an sanar da anemometer (automatic speed measuring devices) da wind vanes attached to the back top of the nacelle. An bayar da signal zuwa electronic microprocessor-based controlling system wanda ya rarraba yaw motor wanda ya zama daidai saboda gearing arrangement don face the air turbine along the direction of the wind.
