Jumlah Masauƙi: Nonsalient-pole generators suna da masauƙi mafi yawa (kamar 12, 16, 24), wanda suka zama ta hanyar rotor, tare da interpolar regions mafi yawa.
Aiki: Nonsalient-pole generators suna amfani a ayyuka da maɗara mai yawa, kamar steam turbine generators da gas turbine-driven generators.
2. Koyarwa na Air Gap
Salient-Pole Generator:
Air Gap Mai Bincike: Saboda masauƙi mai sauƙi, air gap a cikin salient-pole generator yana da tsakiyar masauƙi mai sauƙi da tsakiyar interpolar regions. Wannan air gap mai bincike yana haifar da koyarwa na magnetic field mai bincike, wanda ke haifar da tsari na output voltage waveform.
Harmonic Content: Air gap mai bincike yana iya haifar da harmonic content mai yawa a cikin output voltage, musamman third harmonics.
Nonsalient-Pole Generator:
Air Gap Mai Tsawo: Air gap a cikin nonsalient-pole generator yana da tsawon da yaɗu a duk kungiyar circumference, wanda ke haifar da koyarwa na magnetic field mai tsawo da tsari na output voltage waveform mai tsawo.
Harmonic Content: Air gap mai tsawo yana hada harmonic content, wanda ke haifar da output voltage waveform mai tsawo.
3. Fannin Electromagnetic
Salient-Pole Generator:
Direct Axis da Quadrature Axis Reactance: A cikin salient-pole generator, direct axis reactance (Xd) da quadrature axis reactance (Xq) suna da farko. Xd yana da tsakiyar da yaɗu saboda magnetic flux a kan masauƙi yana da less reluctance, while Xq yana da tsakiyar da yawa saboda higher reluctance a cikin interpolar regions.
Short-Circuit Ratio (SCR): Salient-pole generators suna da short-circuit ratio mai yawa, kamar 1.0 zuwa 2.0. Wannan yana haifar da short-circuit currents mai yawa amma voltage recovery mai yawa a lokacin faults.
Nonsalient-Pole Generator:
Direct Axis da Quadrature Axis Reactance: A cikin nonsalient-pole generator, direct axis reactance da quadrature axis reactance suna da tsawon da yaɗu saboda air gap mai tsawo da symmetrical flux path.
Short-Circuit Ratio (SCR): Nonsalient-pole generators suna da short-circuit ratio mai tsawo, kamar 2.0 zuwa 3.0. Wannan yana haifar da short-circuit currents mai yawa da voltage recovery mai tsawo a lokacin faults.
4. Fannin Mechanical
Salient-Pole Generator:
Rotor Inertia Mai Tsawo: Masauƙi mai tsawo a cikin salient-pole generator yana haifar da rotor inertia mai tsawo, wanda ke haifar da wannan generator a ayyuka da maɗara mai yawa, kamar hydroelectric turbines.
Ventilation da Cooling: Fara mai sauƙi a kan masauƙi yana haifar da ventilation da cooling performance mai tsawo.
Nonsalient-Pole Generator:
Rotor Inertia Mai Yawa: Tattalin rotor mai yawa a cikin nonsalient-pole generator yana haifar da rotor inertia mai yawa, wanda ke haifar da wannan generator a ayyuka da maɗara mai yawa, kamar steam turbines.
Ventilation da Cooling: Jikin rotor mai sauƙi a cikin nonsalient-pole generator yana haifar da ventilation da cooling mai yawa, wanda ke buƙata specialized cooling systems.
5. Fannin Starting
Salient-Pole Generator:
Starting Torque Mai Tsawo: Saboda masauƙi mai tsawo, salient-pole generators suna haifar da electromagnetic torque mai tsawo a lokacin starting, wanda ke haifar da wannan generator a ayyuka da zama da starting torque mai tsawo.
Nonsalient-Pole Generator:
Starting Torque Mai Yawa: Nonsalient-pole generators suna da starting torque mai yawa amma suna haifar da dynamic response mai tsawo a lokacin high-speed operation.
6. Ayyuka
Salient-Pole Generator:
Suna amfani a ayyuka da maɗara mai yawa, kamar hydroelectric power plants da nuclear power plants. Fannin low-speed a cikin salient-pole generators yana haifar da wannan generator a ayyuka da hydro turbines ko low-speed steam turbines.
Nonsalient-Pole Generator:
Suna amfani a ayyuka da maɗara mai yawa, kamar thermal power plants da gas turbine power plants. Fannin high-speed a cikin nonsalient-pole generators yana haifar da wannan generator a ayyuka da steam turbines ko gas turbines.
Gajarta
Salient-Pole Generator: Yana da masauƙi mai sauƙi, air gap mai bincike, da kuma yana daidaita a ayyuka da maɗara mai yawa kamar hydroelectric generators. Abubuwan da suka fi kyau sun hada da starting torque mai tsawo da cooling performance mai tsawo, amma yana iya haifar da harmonic content mai yawa a cikin output voltage.
Nonsalient-Pole Generator: Yana da jikin rotor mai sauƙi, air gap mai tsawo, da kuma yana daidaita a ayyuka da maɗara mai yawa kamar steam turbine generators. Abubuwan da suka fi kyau sun hada da output voltage waveform quality mai tsawo da short-circuit recovery mai tsawo, amma yana da starting torque mai yawa.
Zabi game da salient-pole generator da nonsalient-pole generator yana daidaita a kan abubuwan da ake buƙata a ayyukan, kamar speed, capacity, starting characteristics, da mechanical da electrical needs na system.
