Nhanganyaya: Kukwira kweBalcony PV uye Dambudziko reReverse Power
Kuchinja kwepasi rose kuenda pakubvisa kabhoni mumhepo kuri kukurudzira shanduko yakanyarara musimba remagetsi mudzimba: masisitimu emagetsi ebharukoni (PV). Kubva "kumapurazi madiki" mudzimba dzekuEurope kusvika kumisika iri kubuda pasi rose, bharukoni PV iri kupa varidzi vedzimba simba rekugadzira simba.
Zvisinei, kushandiswa uku nekukurumidza kunounza dambudziko guru rehunyanzvi: kudzoserwa kwemagetsi kumashure. Kana sisitimu yePV ikapa magetsi akawanda kupfuura anoshandiswa nemhuri, simba rakawandisa rinogona kudzokera kugrid yeruzhinji. Izvi zvinogona kukonzera:
- Kusagadzikana kweGrid: Kuchinja-chinja kwemagetsi kunovhiringidza kunaka kwesimba remuno.
- Njodzi Dzekuchengetedza: Njodzi dzevashandi vemagetsi avo vangave vasingatarisiri macircuit aripo kubva pasi perwizi.
- Kusatevedzera Mutemo: Makambani mazhinji anorambidza kana kuranga vanhu vasingatenderwe kupinda mu grid.
Apa ndipo panoshandiswa Reverse Power Protection Solution ine hungwaru, yakavakirwa pamudziyo wekutarisa wakanyatsojeka seZigBee Power Clamp, kuti pave nehurongwa hwakachengeteka, hunoenderana nezvinodiwa, uye hunoshanda zvakanaka.
Mhinduro Yekutanga: Mashandiro Anoita Sisitimu Yekudzivirira Simba Rese
Sisitimu yekudzivirira simba rekudzoka kumashure inzira yakangwara.Mita yeZigBee Power Clampinoshanda se "maziso," ukuwo gateway yakabatana uye inverter controller zvichiumba "uropi" hunoita basa.
Nheyo Yekushanda Muchidimbu:
- Kutarisa Nguva Chaiyo: Chinovhara magetsi, senge PC321 model, chinogara chichiyera mafambiro emagetsi uye hukuru hwekufamba kwemagetsi panzvimbo yekubatanidza magetsi nekushandisa high-speed sampling. Chinotevedzera ma parameter akakosha seCurrent (Irms), Voltage (Vrms), uye Active Power.
- Kuona: Kunoona ipapo ipapo kana simba ratanga kuyererakubvaimbatogrid.
- Chiratidzo & Kudzora: Chinovhara chinotumira data iri kuburikidza neZigBee HA 1.2 protocol kuenda kune gateway inoenderana nehome automation kana system management system. Sisitimu yacho inozotumira murairo kune PV inverter.
- Kugadziriswa kweMagetsi: Iyo inverter inoderedza simba rayo rekuburitsa magetsi kuti rienderane nekushandiswa kwemagetsi kwemba ipapo ipapo, zvichibvisa kuyerera kwemagetsi kubva pakudzokera shure.
Izvi zvinogadzira sisitimu ye "Zero Export", zvichiita kuti simba rese rezuva rishandiswe munharaunda.
Zvinhu Zvikuru Zvekutsvaga Mumhinduro Yepamusoro Yekutarisa
Pakusarudza mudziyo wekutarisa wepakati wemapurojekiti ako ePV ebhalkoni, funga nezvezvinhu izvi zvakakosha zvehunyanzvi zvichibva pahunyanzvi hwePC321 Power Clamp.
Magadzirirwo ehunyanzvi muchidimbu:
| Chinhu | Tsanangudzo & Nei Zvichikosha |
|---|---|
| Protocol isina waya | ZigBee HA 1.2 - Inobvumira kubatanidzwa kwakanaka uye kwakarongeka nemapuratifomu makuru ekugadzirisa dzimba nemagetsi kuti pave nekudzora kwakavimbika. |
| Kururama Kwakagadziriswa | < ±1.8% yekuverenga - Inopa data rakavimbika zvakakwana kuti iite sarudzo dzakanyatsojeka dzekudzora uye kuve nechokwadi chekuti hapana kutumira kunze kwechokwadi. |
| MaTransformer Emazuva Ano (CT) | Sarudzo dze75A/100A/200A, Kururama < ± 2% - Inochinjika kune saizi dzakasiyana dzemutoro. MaCT ane plug-in, ane mavara anodzivirira zvikanganiso zvewaya uye nguva yekuisa slash. |
| Kuenderana kwechikamu | Masisitimu echikamu chimwe chete uye chechitatu - Anoshandiswa zvakasiyana-siyana pakushandisa dzimba dzakasiyana-siyana. Kushandiswa kwe3 CTs kune chikamu chimwe chete kunobvumira kurongeka kwakadzama kwemutoro. |
| MaParamita Akayerwa Zvikuru | Current (Irms), Voltage (Vrms), Active Power & Energy, Reactive Power & Energy - Dataset yakazara yekunzwisisa zvizere system uye kutonga. |
| Kuiswa & Dhizaini | Njanji yeDIN-Rail (86x86x37mm) - Inochengetedza nzvimbo mumabhodhi ekuparadzira. Yakareruka (435g) uye iri nyore kuisa. |
Kupfuura Pepa Reruzivo:
- Chiratidzo Chakavimbika: Sarudzo yeantenna yekunze inovimbisa kutaurirana kwakasimba munzvimbo dzakaoma dzekuisa, izvo zvakakosha kuti pave nehurongwa hwakasimba hwekudzora.
- Kuongororwa Kwebasa: Kugona kuongorora maparamita akaita seReactive Power kunogona kubatsira mukuongorora hutano hwese hwesystem uye hunhu hwesimba.
Mibvunzo Inowanzo bvunzwa (FAQ) yeVanyanzvi
Mubvunzo wekutanga: Sisitimu yangu inoshandisa Wi-Fi, kwete ZigBee. Ndingashandisa izvi here?
A: PC321 yakagadzirirwa ZigBee ecosystem, iyo inopa network yakagadzikana uye ine simba shoma yakakodzera maapplication akakosha ekudzora senge reverse power protection. Kubatanidzwa kunoitika kuburikidza neZigBee-compatible gateway, iyo inogona kutumira data kupuratifomu yako yegore.
Mubvunzo wechipiri: Sisitimu iyi inobatana sei nePV inverter yekudzora?
A: Chinovhara magetsi hachidzore inverter zvakananga. Chinopa data renguva chaiyo kune logic controller (inogona kuva chikamu chegateway rekushandisa otomatiki kumba kana system yakatsaurirwa yekutonga simba). Chinovhara magetsi, kana chagamuchira chiratidzo che "reverse power flow" kubva ku clamp, chinotumira murairo wakakodzera we "curtail" kana "reduce output" ku inverter kuburikidza neinterface yayo inotsigirwa (semuenzaniso, Modbus, HTTP API, dry contact).
Mubvunzo wechitatu: Kururama kwakakwana here pakubhadharisa makambani emagetsi zviri pamutemo?
A: Kwete. Mudziyo uyu wakagadzirirwa kutarisa nekushandisa simba, kwete kubhadharisa mashandisirwo emagetsi. Kururama kwawo kwakanyanya (<±1.8%) kwakanakira logic yekudzora uye kupa data rekushandisa rakavimbika kune mushandisi, asi hauna zvitupa zveMID kana ANSI C12.1 zvinodiwa pakuyera mari inowanikwa nemagetsi zviri pamutemo.
Mubvunzo wechina: Ndeipi nzira yekuisa yakajairika?
A:
- Kuisa: Batanidza chinhu chikuru paDIN rail mubhodhi rekugovera.
- Kuisa CT: Kudzima simba remuchina. Batanidza maCT ane mavara akatenderedza mitsetse mikuru yemagetsi.
- Kubatanidza Voltage: Batanidza yuniti ku voltage yemutsara.
- Kubatanidzwa kweNetwork: Batanidza mudziyo neZigBee gateway yako yekubatanidza data uye kugadzirisa logic yekudzora.
Batana neNyanzvi muSmart Power Metering uye PV Solutions
Kune vanobatanidza masisitimu nevanogovera, kusarudza mubatsiri wetekinoroji akakodzera kwakakosha sekusarudza zvikamu zvakakodzera. Unyanzvi mukuongorora metering nekunzwisisa kwakadzama mashandisirwo e photovoltaic zvakakosha pakuona kuti chirongwa chinobudirira uye kuti sisitimu irambe yakavimbika kwenguva refu.
