Harmonic phenomena mumagetsi masisitimu: inokonzera, mhedzisiro, uye njodzi

Harmonicszvinonyanya kutsoropodzwa kazhinji kazhinji wakacherekedzwa phenomenon mumagetsi. Ivo vanomiririra kukanganisa kweiyo yakakodzera sinusoidal waveform of voltform kana zvazvino, zvinoitika nguva zhinji izvo zviyero zvevazhinji zvehuwandu hwehuwandu (i., 50 hz kana 60 hz kana 60 hz). Nepo Huristonics iri midziyo mune zvemazuva ano masystems, kuvapo kwavo kusingadzoreki kunogona kutungamira kumhedzisiro yakashanda uye yemari. Chinyorwa ichi chinoongorora zvinokonzeresa zvazvo, zvinokanganisa, uye njodzi.

Chii chinokonzeresa Hwaronics?

HarmonicsZvikuruzvo zvinobva kune nonlinear mitoro-zvishandiso izvo zviripo zvisina kufanana neSinusoidal voltage altage. Mienzaniso yakajairika inosanganisira:

Variable Frequency Drives (VFDS) mumaindasitiri motors, switch-mode magetsi zvinhu (i.efa, masisitiri ekushandisa), masisitimu ekushandisa (UPS), uye zvigadzirwa zvemagetsi zvekushandisa zvemagetsi. Iyi mitoro inovhiringidza kuyerera kwazvino, inogadzira yakasvibiswa mavheti. Semuenzaniso, A VFD inogona kutora yazvino mumapururu kwete yekuenderera mberi sine wave

Ndezvipi zvinokonzerwa neHarmonics?  

Hanyonics degrade mhando yemhando uye impose yakakosha yakavanzika mari pane iyo Simba Zvivakwa:  

Harmonics inokonzeresa simba kurasikirwa uye inowedzera mutengo. Semuenzaniso, cheshanu-kurongeka discemonic mafungu anogona kukonzera kusvika pa15% yekuwedzera simba marara mune yekuparadzira systems (U.S. department rekutsvaga kwesimba). Uku kusakwana kunogona kutungamira kune yakakwirira yemagetsi zvikwereti.  

Zvinogona kukonzera kukuvara kwemidziyo uye kuderedza hupenyu, sezvinoita maPalmonic mafungu anogadzira Eddy maCounds uye hystesis kurasikirwa, zvichitungamira pakunyanyisa. Shanduko dzinoshanda munharaunda dzakakwirira-dzakawanda dzinogona kukundikana 30-50% nekukurumidza kupfuura yavo latedpypan. Pamusoro pezvo, Harmonics inogona kukonzera resonance, inotungamira kuCapcititit yekutora uye inogona kuputika kana moto. Uyezve, mune matatu-phatu masisitimu, yechitatu-yekuraira Harmonics (3rd, 9, etc.) kuunganidza pamutsetse wezvematongerwo enyika, zvingangoita kuti zvive pamusoro pekunyanyisa.  

Harmonics inogona kuitawo kukanganisa, kunyanya mumidziyo inonamira senge michina yekurapa, zviridzwa zvekurapa, kana nzvimbo yedata maseva iyo yakachena pane yakachena pasimba rakachena. Voltage kukanganisa kwakakonzerwa neHarmonics kunogona kukonzera kutadza kwemidziyo, uori hwe data, kana isina kubviswa nguva.

Nzvimbo dzekutevedzera uye dzidzo dzekuchengetedza dzakabatana neHarmonics zvakare dzinotsoropodza. Kupfuura miganhu yeHarmonic yakatsanangurwa mune zviyero senge IEEE 519-2022 inogona kukonzera mafiramu ekugadzirisa. Pamusoro pezvo, zvishandiso zvinonyangadza zvinogona kuumba njodzi dzengozi uye njodzi dzekuchengetedza.

Semunhu anogadzira nyanzvi uye anotengesa, tinopa zvigadzirwa zvemhando yepamusoro. Kana iwe uchifarira zvigadzirwa zvedu kana uine chero mibvunzo, ndapota inzwa wakasununguka kutaura nesu.
