Nhanganyaya

Hunhu hweSimba (PQ) idambudziko kune vese vatengi vemagetsi nevashandi vemagetsi pamatanho ese ekushandisa. Rimwe rematambudziko ePQ iharmonics inova sinusoidal component ye periodic wave kana huwandu hune frequency iri integral multiple ye fundamental frequency, kureva, 50Hz kana 60Hz [1]. Harmonic voltages inoitika nekuda kwe current harmonics, iyo inogadzirwa uye inodhonzwa ne non linear electronic loads, inopinzwa mu supply system [2].

Kuyerwa kweHarmonic distortion paindasitiri

Kuti tione huwandu hwekukanganiswa kwesimba remagetsi muindasitiri, kutarisa kunofanirwa kuitwa panzvimbo dzekupinda muindasitiri paPoints of Common Coupling (PCC), nzvimbo yekubaya pa15kV feeders. Zvisinei, sezvo daro nemutsetse wekudzivirira, kubva kuPCC kusvika ku primary yetransformer zvisinganyanyi kukosha, primaries dzinotorwa sePCC sezvakaratidzwa pamufananidzo 1 [2].

Kukanganiswa kweharmonic muindasitiri kunoyerwa apo michina yese iri kushanda panguva imwe chete, kuti vaone hunhu hwehuwandu hwemitoro yeindasitiri uye kuunganidzwa kwedata kunoitwa kuburikidza nekuyera zvakananga. Mushure mekuita ongororo yakakodzera, data rakaunganidzwa rinoverengerwa uye rinoenzaniswa nemitengo inogamuchirika yakaiswa nemiyero yeIEEE inokurudzirwa yemaitiro ekutonga harmonic [28].

Tafura 1: Miganhu yekukanganisika iripo yemasisitimu ekugovera akajairika (120V kusvika 69 000V) [2]. Mufananidzo 1: Kutarisa nzvimbo nenzvimbo yekubatanidza kwakajairika. Kukanganisika kweharmonic muindasitiri kunoyerwa apo michina yese iri kushanda panguva imwe chete, kuti ione hunhu hwehuwandu hwemitoro yeindasitiri uye kuunganidzwa kwedata kunoitwa kuburikidza nekuyera zvakananga. Mushure mekuita ongororo yakakodzera, data rakaunganidzwa rinoverengerwa uye rinoenzaniswa nemitengo inogamuchirika yakaiswa nemiyero yeIEEE inokurudzirwa tsika yekudzora harmonic [28].

Current yepfupi uye 15kV feeder paPCC zvinoverengerwa kuva 10kA uye 1000A zvichiteerana, izvo zvinopa I_SC/Ini_Lchiyero chiri pakati pe

Voltage yepamusoro uye zviri mukati memagetsi zvinosanganiswa nemagetsi painoshanda pakazara zvinoratidzwa mutafura 3.

Kubva padata rakanyorwa, zvinoonekwa kuti ma "harmonic currents" makuru ndiwo ma "5".^thuye 7^thmaharmoniki uye huwandu hwese hweTHD huripo hwezvikamu zvitatu izvi i18.10%, 18.33% uye 18.44%, zvichiteerana paPCC iyo iri pamusoro pemitemo yeIEEE, kureva, 5%. Sezvo maTHD aripo ari pamusoro pemakoshesi akajairwa, mafirita eharmonic akatuned kamwe chete, akatuned kaviri, akapfuudzwa zvakanyanya uye ane maparamita akagadzirwa anoshandiswa kuderedza kukanganiswa kweharmonic uye mashandiro avo anoenzaniswa zvichibva pahuwandu hweTHD huripo kana mafirita ese eharmonic ashandiswa.

Musimboti wekushanda

Dunhu rinoshandiswa kuderedza kukanganiswa kweharmonic rinoratidzwa pamufananidzo 2. Rine maswitch, single tuned, double tuned, high pass uye c-type harmonic filters pamwe chete nemutoro. Nekuda kwekusakwana kwemutoro wesimba remaindasitiri, sezvo ma harmonic currents achiiswa musystem, voltage uye current waveforms zvinokanganiswa. Ma Harmonic filters ane ma values ​​akagadzirwa uye ma switch anoenderana anoshandiswa ega kuenzanisa mashandiro ema harmonic filters uye anobatidzwa ON uye anodzimwa kuti aderedze harmonic distortion. Pakutanga, single tuned filter switch inovhurwa nepo mamwe ma switch ari OFF. Zvadaro, high pass filter switch inovhurwa nepo mamwe ma switch ari OFF. Tevere, double tuned filter switch inovhurwa nepo mamwe ma switch ari OFF. Pakupedzisira, C-type filter switch inovhurwa nepo mamwe ma switch ari OFF. Kuti zvive nyore, chikamu chimwe chete ndicho chinoonekwa sechisina muzvikamu zvitatu sezvo simba rinotorwa kubva muchikamu chimwe chete kuderedza harmonic distortion kuratidza control circuit.

Mhedzisiro yeKutevedzera

Kukanganiswa kweharmonic kwakaedzwa uchishandisa software yeMATLAB/SIMULINK. Mafirita eharmonic akadai se single tuned, double tuned, high pass uye c-type akaedzwa ne values ​​dzakagadzirirwa kuenzanisa mashandiro avo mukuderedza harmonic distortion yakaitika mu industrial power system nekuda kwe non linear loads. Voltage uye current waveforms kubva ku source side uye load side usati washandisa harmonic filters anoratidzwa pazasi kuti aenzaniswe. Indasitiri iyi ine non-linear loads dzinopihwa ne utility kubva ku substation iri pedyo uye non-linear loads dzinodhonza harmonic currents ye distracted waveform. Simulation inoitwa ne values ​​dzakagadzirirwa mafirita eharmonic ane nominal line to line voltage ye400V, operating frequency ye50Hz, nominal reactive power ye50KVAR, quality factor ye7 uye tuning frequency yakagadzirirwa 5^thuye 7^thmaharmoniki.

Magadzirirwo emagetsi nemagetsi asati ashandiswa mafirita eharmonic anoratidzwa mumufananidzo 3.

Indasitiri iyi ine zvinhu zvisingaenderane nemutsetse zvinopihwa neutility uye zvinhu izvi zvinotora voltage yakakanganiswa yeharmonic uye waveform yemagetsi sezvakaratidzwa pamufananidzo 3 uye kubva pakuongorora kweFast Fourier Transform (FFT) sezvakaratidzwa pamufananidzo 4, kukosha kweTHD kuri 18.33%, iyo iri pamusoro pemuganhu unogamuchirwa weIEEE, kureva 5% yechidzidzo ichi. Saka, kuti kuderedze kukanganiswa kweharmonic, mafirita eharmonic akagadziriswa kamwe chete, akagadziriswa kaviri, akakwira kupfuura uye emhando yec-type akagadzirwa uye akaiswa panzvimbo yakakodzera pasystem yemagetsi eindasitiri; nekudaro, kukanganiswa kweharmonic kunoderedzwa uye mashandiro avo anoenzaniswa.

Mhedziso

Mupepa rino, kuenzanisa mashandiro emafirita eharmonic musystem yemagetsi eindasitiri yekuderedza harmonic distortion kuri kudzidzwa. Kukanganiswa kweharmonic kunotorwa neindasitiri kwete-linear loads kunopa THD kukosha kwe18.33%. Uye kana single tuned harmonic filter ikashandiswa, THD inoderedzwa kusvika pa5.08%. Nepo, kushandiswa kwehigh pass harmonic filter kunopa THD ye5.09%. Double tuned harmonic filter inopa 4.00% THD kukosha. Pakupedzisira, kushandisa c-type harmonic filters 4.68% THD kukosha kunowanikwa. Nekuda kweizvozvo, kubva mumhedzisiro yekufananidzira uye kuongororwa kweFFT, zvinoonekwa kuti double tuned harmonic filters inopa mashandiro ari nani pane single tuned, high pass uye c-type harmonic filters mukuderedza harmonic distortions kusvika pahukuru hunogamuchirwa hwakatarwa neIEEE standards, kureva pasi pe5% yechidzidzo ichi uye zvinokurudzirwa kuti indasitiri ishandise double tuned harmonic filter panzvimbo yechipiri yetransformer kubvisa kupisa kwakawedzerwa, manyepo ekugumburwa uye kusashanda zvakanaka kwemidziyo nekuda kweharmonics izvo zvinokonzera kurasikirwa kwekugadzira kuindasitiri.
