Ka keketseho e tsoelang pele ea litšenyehelo tsa batho, lik'hamphani tse ngata le ho feta mafapheng a fapaneng li se li qalile ho hlahisa mela ea tlhahiso e ikemetseng ho fihlela ts'ebetso e ikemetseng, kopano le liteko.Likarolo tse ling tse tloaelehileng tsa mochini li etsoa ka mehala ea tlhahiso e ikemetseng.

Lintho tse silafatsang tsa Harmonic li rarahane ebile lia fetoha.Ho ka 'na ha e-ba le li-harmonics tse bakoang ke tsona, li-harmonics tse tsoang ho marang-rang a phahameng a motlakase kapa li-harmonics tse bakoang ke basebelisi ba tloaelehileng ka beseng e le' ngoe.
Kotsi ea li-harmonics ho lisebelisoa tse nepahetseng haholo.Ho na le mechini le lisebelisoa tse ngata tse nepahetseng haholo ts'ebelisong ea matla a laboratori kapa mohala oa tlhahiso o ikemetseng.
Maemong a mangata, sesebelisoa sena, sete ea jenereithara, ke phofu ea maqhubu a pulsating.Harmonics e tla beha ts'ebetso e tloaelehileng ea lisebelisoa tsa laboratori kotsing, e le hore liteko tse entsoeng li ke ke tsa fihlela litlhoko.Harmonics e ka boela ea ama molaoli ea bohlale le software ea taolo ea sistimi ea mohala oa tlhahiso ea othomathike, e bakang liphoso ho lisebelisoa tsa sistimi ea taolo ea othomathike.Lilaboratoring tsa rona tse ngata tsa boemo ba k'hamphani, likhoele tsa tlhahiso ea othomathike ea lik'hamphani tse etsang lisakerete, le mehala ea boiketsetso ea lik'hamphani tsa indasteri ea pampiri, ho bile le ho hloleha ha mochini ho bakoang ke maqhubu a feteletseng.

Boleng ba mosebedisi ba Harmonic Governance
Fokotsa likotsi tsa li-harmonics, thibela matla a motlakase a sebetsang a bakoang ke li-harmonics ho eketseha le ho senya liphoso tse fapaneng tse tloaelehileng joalo ka lisebelisoa tsa motlakase, le ho ntlafatsa ntlha ea polokeho ea sistimi ea phepelo ea motlakase.
Laola li-harmonics, fokotsa tšebeliso ea hona joale ea harmonic e kentsoeng tsamaisong, le ho finyella litlhoko tse tloaelehileng tsa k'hamphani ea rona;
Matšeliso a matla bakeng sa meroalo e sebetsang, matla a tšoanelehang, le thibelo ea likotlo ho tsoa ho lik'hamphani tsa phepelo ea motlakase.

Mathata ao o ka kopanang le ona?
1. Mohala oa tlhahiso o sebelisa lisebelisoa tse ngata tsa ho laola lebelo la motlakase oa AC le li-motor, e leng se lebisang ho tšilafalo ea ka hare ea tšilafalo ea tikoloho le likotsi tsa polokeho ea boleng ba matla k'hamphaning;
2. Harmonics e rarahane ebile e fetoha, ho thata ho e laola, e ama ka botebo ts'ebetso e tloaelehileng le e sireletsehileng ea lisebelisoa tsa motlakase moleng oa tlhahiso.
3. Thepa ea mats'eliso ea matla a khale a sebetsang hangata e senyeha, ebile e etsa hore li-harmonics li be kholoanyane.

Tharollo ea rona:
1. Ho ea ka boemo ba hona joale ba pulse ea tsamaiso, sekhahla sa ho arabela ha phallo sea utloahala, 'me thepa ea matšeliso ea ts'ireletso ea data e tsitsitseng e khethiloe ho lefella mojaro o sebetsang oa tsamaiso le ho ntlafatsa matla a tsamaiso;
2. Sebelisa filthara e sebetsang ea Hongyan APF ho laola li-harmonics tsa sistimi, le ho fokotsa litaba tsa maqhubu a sistimi ho ba ka tlase ho boleng ba moeli bo hlokoang ke litekanyetso tsa k'hamphani ea rona.
3. Adopt Hongyan letoto la lihlooho tse sefang sesebediswa, moralo LC tuning parameters, buseletsa reactive matla ha a ntse a laola tsamaiso tšobotsi harmonics, le ntlafatsa matla ntlha.
4. Hongyan letoto la dynamic var jenereithara li sebelisoa ho dynamically fana ka matla a sebetsang ho karolo ka 'ngoe ea tsamaiso le ho sebetsana le harmonics tsohle tsa tsamaiso ka nako e le 'ngoe.
