Yiziphi izinkinga zekhwalithi yamandla angakwazi ukuxazulula izinhlelo zamandla

Isihlungi samandla asebenzayoIdivaysi ethuthukisiwe ye-elektroniki ye-elektroniki esetshenziselwa ukuxazulula izinkinga zekhwalithi yamandla ezibangelwa imithwalo ye-nonlinear ezinhlelweni zamandla. Kukhiqizwa ngentshiseko imidlwane yesinxephezelo maqondana namapharamitha we-harmonics, amandla asebenzayo, futhi angenakulinganiswa kwamanje kugridi yamandla ngokuqapha kwangempela, ngaleyo ndlela uzuze ukuphathwa okusebenzayo kwegridi yamandla. Ukuhlunga kwamandla okusebenzayo kudlala indima ebalulekile ekuxazululeni izinkinga zekhwalithi yamandla ohlelweni lwamandla. Lokhu okulandelayo kuzoxoxa ngokuningiliziwe ukuthi yiziphi izinkinga abangazixazulula.

1. Ukuhlunga kwamandla okusebenzayo kungalawula ngempumelelo ukungcoliswa kwe-harmonic kugridi yamandla.

Imithwalo engenayo ye-nonlinear, efana nama-rexifers kanye nama-frequency aguqukayo, ikhiqize inani elikhulu le-harmonics ngesikhathi sokusebenza, esingangcolisa kakhulu igridi yamandla, okuholela ekuhlanekezeni i-valeform, ukuncishiswa kwemishini yamandla, nokuvuselelwa kwemishini yamandla, kanye nokushisa kwemishini. Ukuhlunga kwamandla okusebenzayo kungasusa ngempumelelo i-harmonics ngokukhiqiza imali yokunxephezela okuphambene nalokho, ukubuyisela ama-waveform we-valege wegridi yamandla ku-waveform ye-saveform kanye nokwenza ngcono amandla.

2. Ukuhlunga kwamandla okusebenzayo kunganxephezela amandla asebenzayo kugridi yamandla.

Amandla asebenzayo uhlobo lwamandla angenamsebenzi kugridi yamandla, ekhulisa ukulahleka komugqa, anciphise ukusebenza kahle kwemishini, futhi abuse ukuguquguquka kwamandla okushintshashintsha kwamandla kugridi. Ukuhlunga kwamandla okusebenzayo kungaqapha amandla okusebenza ngegridi yamandla ngesikhathi sangempela futhi kufezekisa ukunxephezelwa kwezinxephezelo ezihambisanayo, ukuthuthukisa ukuncishiswa kwamandla wegridi yamandla, ukunciphisa ukulahleka komugqa, kanye nokwenza ngcono imishini esebenza kahle.

I-3. Ukuhlunga kwamandla okusebenzayo nakho kungaxazulula inkinga yokungalinganiseli kugridi yamandla.

Ekusebenzeni kwangempela, imisinga engalingani kaningi yenzeka kugridi yamandla ngenxa yezici ezinjengembala wokungalingani kanye nomugqa we-asymmetry. Le misivu engenakulinganisela ingaholela ekuvuseleleni ukufudumeza, ukunciphisa ukusebenza kahle, futhi kulimaze nemishini. Ukuhlunga kwamandla okusebenzayo kungaqapha ama-currents angalinganiseli kugridi yamandla ngesikhathi sangempela futhi kukhiqize ngentshiseko ama-complication Resign ahambisanayo, ngaleyo ndlela uzuze ukuphathwa kwemisinga engalingani futhi uvikele ukusebenza okuphephile kwemishini.

Ngaphezu kwezinkinga ezingenhla, izihlungi zamandla ezisebenzayo nazo zingaxazulula ezinye izinkinga zekhwalithi yamandla kugridi yamandla, zigange, amaconsi, njll. Lezi zinkinga zingaba nomthelela ojwayelekile ekusebenzeni okujwayelekile kwemishini, futhi kuholele ekulimaleni kwemishini. Ukuhlunga kwamandla okusebenzayo kungaqapha lezi zinkinga zekhwalithi yamandla kugridi yamandla ngesikhathi sangempela futhi kukhiqiza ngentshiseko ama-currents wesinxephezelo esihambisanayo, ngaleyo ndlela uzuze ukuphathwa kwalezi zinkinga nokwenza ngcono ukuqina nokwethembeka kwegridi yamandla.

Ngokufigqiwe,Ukuhlunga kwamandla okusebenzayoAmadivayisi anamandla kagesi anamandla okuxazulula ngempumelelo ukungcoliswa kwe-harmonic, isinxephezelo samandla asebenzayo, ukulawulwa okungalinganiselwe kwamanje, nezinye izinkinga zekhwalithi yamandla kugridi yamandla. Ngokuthuthuka okuqhubekayo nokwanda kobuchwepheshe be-Power Electronics, izihlungi zamandla asebenzayo zizodlala indima ebaluleke kakhulu ezinhlelweni zamandla akwamandla ezizayo, ukuhlinzeka ngeziqinisekiso eziqinile zokusebenza okuzinzile kwama-Power Systems kanye nokusebenza okuthembekile kwemishini. Ngasikhathi sinye, ngokuthuthuka okuqhubekayo kwezidingo zabantu zekhwalithi yamandla, isidingo semakethe sokuhlunga kwamandla asebenzayo sizoqhubeka nokukhula, ukuletha isikhala semakethe esibanzi sokwakhiwa kwezimboni ezihlobene.
