Tātaritanga Hāmoni i roto i ngā Pūnaha Mana
Pendahuluan
I tēnei ao e piki haere ana te matatau me te whakawhirinaki ki te hangarau, ko te kounga o te hiko e tukuna ana ki ngā kaihoko kei te piki haere te noho hei āhuatanga nui e tika ana kia arohia. Ko tētahi o ngā āhuatanga matua ka pā ki tēnei kounga ko te noho mai o ngā hauropi i roto i te pūnaha hiko. Ko ngā hauropi he ngaru sinusoidal me te auau teitei ake i te auau taketake o te pūnaha hiko. I roto i te horopaki o ngā pūnaha hiko, ko te tātari hauropi e pā ana ki te tukanga o te tautuhi me te whakakore i ngā pānga kino o ēnei hauropi. Ka whakaratohia e tēnei tuhinga he arotake hohonu o ngā hauropi, ō rātou pūtake, ō rātou pānga ki ngā pūnaha hiko, me ngā tikanga mō te tātari me te whakatau i aua mea.
Te Mārama ki te Harmonica
I roto i te tikanga hangarau, ka taea te tautuhi i ngā hauropi hei wāhanga sinusoidal o tētahi tohu ā-wā, ko ōna auau he maha o te auau taketake. Ko te auau taketake ko te auau matua o te tohu taketake, ko te tikanga he 50 Hz, he 60 Hz rānei i roto i tētahi pūnaha hiko. Hei tauira, mēnā ko te auau taketake he 50 Hz, ka 100 Hz te hauropi tuarua, ko te hauropi tuatoru he 150 Hz, ā, pērā tonu.
Ngā Pūtake Harmonic i roto i ngā Pūnaha Mana
Ko ngā āhuatanga o te harmonika i roto i ngā pūnaha hiko ka puta mai i ngā taputapu hiko kore-raina. Ko ētahi o ngā pūtake matua o ngā harmonika ko:
1. Ngā Pūrere Hiko: Ko te nuinga o ngā taputapu whare me ngā taputapu ahumahi hou pēnei i ngā rorohiko, ngā pouaka whakaata, me ngā taputapu e whakahaerehia ana e te hiko, he pūtake hiko kāore e rārangi.
2. Ngā Kaitahuri Hiko: Ko ngā taputapu pēnei i ngā whakatikatika, ngā kaitahuri, me ngā kaitahuri ngā tino take o ngā harmonika. Ka puta tēnei i te huringa mai i te AC ki te DC, i te hurihanga rānei, e uru ana ki ngā āhuatanga kore-raina.
3. Ngā Mōta Ahumahi: Ka whakaputa hoki ngā mōta AC e whakahaerehia ana me ngā puku tere rerekē (VSD) i ngā harmonika.
4. Ngā Taputapu Hikohiko Mana: Kei roto i tēnei kāwai ngā taputapu pēnei i te UPS (Uninterruptible Power Supply) me ngā pūnaha rama kei roto ngā parepare hiko.
Te Pānga o ngā Hāmoni ki ngā Pūnaha Mana
Ka pā mai pea ētahi raruraru nui i roto i ngā pūnaha hiko nā te whakamahi i ngā hāmoni, me ngā taputapu me ngā hanganga whatunga hiko tonu. Ko ētahi o ngā pānga nui ko:
1. Te wera rawa: Ka taea e ngā hāmonika te wera rawa i roto i ngā whakawhiti hiko, ngā kaiārahi hiko, me ngā mīhini. Ka taea e tēnei te whakateretere i te pirau o te whakamarumaru me te whakaiti i te roa o te ora o ngā taputapu.
2. Ngā Ngaronga Mana: Ka taea e te noho mai o ngā harmonics te whakanui ake i ngā ngaronga mana i roto i te pūnaha tohatoha hiko, ka heke ai te whai huatanga o te mahi.
3. Te Rahunga o ngā Taputapu: Ko te tairongo o ngā taputapu hiko ki ngā harmonika ka raru pea i te wā wawe, i te wā rānei e pakaru ohorere ai.
4. Te Whakararuraru Whakawhitiwhiti Kōrero: Ka taea e ngā harmonics te whakararuraru i ngā pūnaha whakawhitiwhiti kōrero me ngā pūnaha whakahaere nā te haruru e puta mai ana.
5. Te Whakaohooho: Ka taea e ētahi huinga o ngā haurore me ngā āhuatanga whatunga te whakaputa i te whakaohooho, ka taea ai te whakaputa i ngā ngaru hiko me te iahiko ka kino ai ngā taputapu.
Tikanga Tātari Harmonic
1. Tātaritanga Whakawhitinga Fourier Tere (FFT): He tikanga noa te FFT mō te huri i tētahi tohu rohe-wā ki te rohe auau. Mā tēnei ka taea te tautuhi i te whānuitanga o te oro o tētahi tohu AC. Mā te FFT, ka taea e tātou te whakatau i te kaha me te āhua o ia wāhanga oro.
2. Huarahi Ine Tika: Mā te ine tika mā te whakamahi i ngā taputapu ine haurore pēnei i ngā tātari kounga hiko ka taea te whakarato raraunga wā-tūturu mō te kounga hiko me ngā taumata haurore.
3. Te Whakatauira me te Whakaata: Ka taea te whakamahi i ngā taputapu whakaata pēnei i a MATLAB/Simulink, i ngā pūmanawa motuhake rānei pēnei i a ETAP hei whakatauira me te tātari i ngā pānga harmonic i roto i ngā pūnaha hiko.
4. Huarahi Tātari: I runga i te ariā ara iahiko me te tātaritanga āwhata e āhei ai te tatau i ngā kawenga ā-hauora i runga i ngā āhuatanga o te pūtake me te whatunga hiko.
Te Whakaoti Rapanga Harmonic
1. Te Whakamahi i ngā Tātari Harmoni: Ko tētahi o ngā otinga tino noa ko te tāuta i tētahi tātari harmoni, ahakoa he korekore, he korekore rānei. Kua hangaia ngā tātari korekore me ngā wāhanga inductance, capacitance, me te ātete hei whakakore i ētahi auau harmoni. Ko ngā tātari hohe, i tētahi atu taha, ka whakamahi i ngā wāhanga hiko mana matatau ake mō ngā tono hihiri ake.
2. Hoahoa Taputapu Whakapai Ake: Mā te whiriwhiri me te hoahoa i ngā taputapu hiko he iti ngā āhuatanga orooro ka taea te whakaiti i te whakaputanga orooro mai i te tīmatanga.
3. Te Tohatoha Kawenga Taurite: Mā te karo i te kukū o ngā kawenga kore-raina i te wāhi kotahi ka āwhina anō hoki ki te whakaiti i ngā taumata harmonic.
4. Te Whakamahinga o ngā Whakawhitiwhiti Zig-Zag: Ka taea te whakamahi i ngā whakawhitiwhiti kua hangaia hei whakaiti i ngā harmonika i roto i ngā pūnaha tohatoha hiko.
5. Kaiwhakatikatika Hāmoni Kaha: Ka mahi tēnei taputapu mā te werohanga i te ia whakamuri mai i ngā hāmoni kua kitea, ā, ka hangaia he taurite e whakaiti ana i te pānga kino ki te whatunga hiko.
Whakamutunga
Kāore e taea te wareware i te awe o ngā hauropi i roto i ngā pūnaha hiko i roto i ngā taiao ahumahi me ngā taiao kāinga. Ko te māramatanga hōhonu ki ngā pūtake, ngā pānga, me ngā tikanga tātari o ngā hauropi te taahiraa tuatahi ki te pupuri i te kounga o te hiko. Ko te whakaoti rapanga hauropi me whai huarahi whānui, mai i te hoahoa pūnaha whakapai ake me te whakamahi i ngā tātari whai hua ki te ako mō te hiranga o te whakahaere kounga hiko. I te whanaketanga o te hangarau me te piki haere o ngā tono hiko, ka noho te whakaiti i te hauropi hei wāhanga wero me te mea nui i te heke mai.
