A Simba rekushandura System (PCS)mudziyo wemagetsi wemagetsi wakakwira wakagadzirirwa kushandiswa-kuyera mabhatiri ekuchengetedza simba. Inogonesa kushandurwa kwemafomu emagetsi emagetsi uye bidirectional simba kuyerera, inotsigira DC voltages kusvika ku1500V. PCS inoshandiswa zvakanyanya mumasisitimu ekuchengetedza simba uye renewable simba rekugadzira magetsi.
Iri pakati pebhatiri rekuchengetedza simbauye gidhi remagetsi, ndicho chikamu chakakosha chinoita kuti bidirectional kuyerera kwesimba remagetsi pakati pesimba rekuchengetedza system uye gidhi remagetsi. Inoshandiswa kudzora bhatiri kuti iite inoshanda AC / DC kutendeuka panguva yekuchaja / kuburitsa uye inoita mabasa akakosha e bidirectional magetsi ekushandura simba uye system control.
Iyo PCS Inoshanda sei
Nheyo yekushanda kwePCS ndeyekuzadzisa bidirectional kuyerera uye kuumba shanduko yesimba remagetsi: pakati pe AC neDC mativi, kuburikidza nekuchinja kwekutonga kwemagetsi semiconductor zvishandiso, iyo AC simba kubva kune grid inogadziriswa kuita DC simba rekuchaja bhatiri; kana simba reDC kubva mubhatiri rinopinzwa musimba re AC kuti ridzosere kugridi. Iyi nzira inodzorwa zvine simba neiyo microgrid yekutarisa sisitimu, iyo inogona kuita inogara ichisimba (PQ) kana inogara iripo (CC) inoraira kunyatso kudzora kuyerera kwesimba rekuchaja bhatiri uye kuburitsa (senge peak shaving uye kuzadza mupata), uye panguva imwe cheteyo kutsetseka kushanduka kwesimba rekubuda kwesimba rinochinja-chinja senge simba remhepo uye photovoltaic.
Mukushanda kwegedhi remagetsi, iyo Power Control System (PCS) inotamba akawanda akakosha mabasa:
1. Kuchengetedza kushanda kwegridi kwakagadzikana: Kupa simba rekuchengetedza simba panguva yekusagadzikana kwegridhi, kuve nechokwadi chekuchengetedzwa kwebhatiri kuburikidza nekukurukurirana neBattery Management System (BMS), uye kugonesa makuru-zviteshi zvemagetsi ekuchengetera magetsi kuti zvikwanise kuchinjika pasi pegadziriro yemagetsi uye kugadzirisa hupfumi hwenyika kuburikidza nePCS.
2. Kuona kuti bhatiri rakachengeteka: Kushanda pamwe chete neBMS, kuona kuti mabhatiri achishanda mukati memiganhu isina njodzi uye kudzivirira njodzi dzakaita sekukwirisa uye kuwedzera-kudzikira.
3. Kuvandudza kuchinjika kwehurongwa uye hupfumi: Kunyanya munzvimbo huru-zviteshi zvemagetsi ekuchengetera magetsi, PCS yakakosha pakuwana flexible power system regulation (zvakadai sepeak shaving uye valley filling, frequency regulation) nekuvandudza hupfumi hwehupfumi.
Core maficha uye mabasa ePCS
A PCS (Power Control System) ine hardware yakaita seIGBTs (Insulated Gate Bipolar Transistors), PCBs (Printed Circuit Boards), uye waya netambo. Yayo yakakosha maficha uye mabasa ndeaya anotevera:
Bidirectional Energy Shanduko:A PCS inogona kushandura yakananga ikozvino (DC) kune inoshandura ikozvino (AC) uye zvinopesana, ichigonesa bidirectional simba kuyerera pakati pegridi, mabhatiri, uye mitoro. Semuyenzaniso, mugadziriro yekuchengeta simba, inokwanisa kushandura grid AC kuenda kuDC kuti ichaja bhatiri panguva-yakanyanya kushanda, uye kushandura DC yebhatiri kuita AC kuti idzokere kugridi kana kuti kuendesa mitoro yemuno munguva dzepamusoro.
Precise Power Control:Kuburikidza nemhando yepamusoro yekudzora algorithms, iyo PCS inogona kugadzirisa ukuru uye kutungamira kwekuchaja uye kuburitsa simba munguva chaiyo, kunyatsopindura kune grid kutumira mirairo kana masaini kubva kuBattery Management System (BMS), kuve nechokwadi chekushanda uye kugadzikana kwesimba rekushandura. Semuyenzaniso, inokwanisa kugadzirisa kuchaja uye kuburitsa ikozvino, voltage, uye frequency zvichienderana nekuchinja kwegridi kana mamiriro ebhatiri.
Power Quality Optimization:Iyo PCS ine harmonic kudzvinyirira uye reactive simba muripo mabasa, ayo anogona kuvandudza kunaka kwesimba rekubuda uye kuderedza kupindira kune grid. Mune mamiriro matsva ekugadzira magetsi emagetsi, inogona zvakare kutsvedzerera kushanduka kwemagetsi emagetsi emagetsi emagetsi senge photovoltaics uye simba remhepo, zvichiita kuti magetsi ekugadzira curve agadzikane nekuvandudza kugona kwegridi kugamuchira simba rinogoneka.
Mode Switching uye Dziviriro Mabasa:PCS inotsigira mashandisirwo akawanda, kusanganisira grid{{0}yakabatana nekudzimwa-grid (islanding), uye inogona kukurumidza uye zvisina musono kuchinja pakati pemamodhi akasiyana. Panguva imwe chete, inosanganisa nzira dzakawanda dzekudzivirira dzakaita sekuwandisa kwemagetsi, overcurrent, overtemperature, uye anti-anti Islanding kuti ive nechokwadi chekushanda kwakachengeteka pasi pekukanganisa kana mamiriro asina kunaka, kudzivirira kukuvara kwemidziyo kana tsaona yegridi.
Muchidimbu, PCS ibhiriji rakakosha rinobatanidza kuchengetedza kwesimba uye kutapurirana kwemagetsi, kufambisa kuchinjika kwesimba kutumirwa, kushandiswa kwakanaka, uye kugadzikana kushanda kwegidhi kuburikidza nehunyanzvi uye nehungwaru shanduko yesimba uye manejimendi.
PCS Application Scenarios
Zvichienderana neakasiyana mamiriro ekushandisa, PCS inogona kupatsanurwa muzvikamu zvitatu zvikuru: magetsi ekuchengetedza simba zviteshi, maindasitiri nekutengeserana, uye pekugara. Musiyano mukuru uri mukubuda kwesimba.
Energy Storage Power Stations
Makuru-magetsi emagetsi ekuchengetera magetsi anoita mabasa akawanda akakosha mugadziriro yemagetsi, kusanganisira frequency regulation, voltage regulation, uye backup. Simba ravo rePCS rinowanzosvika megawati nhanho kana pamusoro, iine masimba kubva kune akati wandei megawatts kusvika kumazana emamegawatts. Vane zvinotemesa musoro zvinodikanwa zvekumhanya kwehurongwa hwekupindura uye kurongeka kwekutonga, uye vanofanirwa kuve negridi yakasimba-inogoneka kuchinjika uye yakawanda-muchina unofambirana unokwanisa kuita kuti ive nechokwadi chekushanda kwakachengeteka, kwakanaka, uye kwakagadzikana kwesimba remagetsi panguva yakakura-yakakura bidirectional simba rekushandura. Iwo akakosha musimboti tsigiro unit pakuvaka smart grids.
Industrial and Commercial Energy Storage Systems (PCS)
Masimba emagetsi emaindasitiri uye ekutengesa simba rekuchengetedza masisitimu anowanzo kubva pa50kW kusvika pa500kW. Yakatarisana nekunetsa uye inogara-inochinja mitoro yemagetsi nemamiriro ekushanda, PCS inofanirwa kuve neshanduko inodarika 98.5% uye millisecond-level fault ride- kubudikidza nekugona. Nekuita nemazvo-kuveura uye mupata{9}}nzira yekuzadza "yekuchengetedza magetsi panguva yekudzima{10}}nguva dzepamusoro-soro uye kubuda mukati menguva dzepamusoro," zvinoderedza zvinodhura mutengo wemagetsi kumabhizinesi ne30% -50%. Panguva imwe cheteyo, gidhi rayo kushanduka kwega uye kusamira kwekuchinja mabasa inovimbisa kuenderera kwemagetsi kune yakakosha mitsara yekugadzira kana nzvimbo dzebhizinesi, inovandudza zvakanyanya kuvimbika kwesimba uye kuve muchengeti webhizinesi manejimendi.
Yekugara Energy Storage PCS
MaPCS ekuchengetedza simba rekugara anowanzo pakati pesimba kubva pa5kW kusvika pa10kW. Yayo compact, modular dhizaini inobvumira kuisirwa nyore uye kusanganisa isina musono neakagovaniswa simba sosi senge pamusoro pedenga rezuva simba. Nekuchengeta simba rezuva rakawanda mukati mezuva uye nekupa zvinhu zvemumba manheru, zvinokwanisa kuchengetedza mari yepeak and off-yakanyanya kudhura. Uye zvakare, inopa isina musono backup simba panguva yekudzima kwegidhi, ichienderera mberi nekuona magetsi kuomesesa mitoro yakadai sefiriji, mwenje, uye michina yekutaurirana, nekudaro kugadzira yakachengeteka uye yakazvimirira microgrid mhinduro yeimba.
