1. Chii chinonzi Islanding Phenomenon muGrid-Tied PV Systems?
Tsanangudzo
Chiitiko chechitsuwa chinoitika mugridi-yakasungirirwa photovoltaic (PV) masisitimu kana grid ikasangana nekudzimwa kwemagetsi, asi iyo PV system inoenderera ichipa simba kune yakabatana mitoro. Izvi zvinogadzira "chitsuwa" chenzvimbo yekugadzira magetsi.
Ngozi dzeIslanding
- Njodzi Dzakachengeteka: Njodzi kune vashandi vekushandisa kugadzirisa grid.
- Equipment Kukuvara: Zvikamu zvemagetsi zvinogona kusashanda nekuda kwekusagadzikana kwemagetsi uye frequency.
- Grid Kusagadzikana: Zvitsuwa zvisingadzoreki zvinogona kukanganisa kushanda kwakabatana kwegridhi yakakura.
2. Zvinhu Zvikuru uye Parameters yeInokodzera Inverters
Zvinokosha Zvimiro zveInverters
- Anti-Islanding Dziviriro: Inoshandisa inoshanda uye inongoita yekuona nzira kuti ivhare nekukurumidza panguva yekutadza kwegridi.
- Inoshanda MPPT (Maximum Power Point Tracking): Inokwirisa shanduko yesimba kubva kuPV mapaneru.
- Kushandura Kubudirira Kwepamusoro: Kazhinji> 95% kuderedza kurasikirwa kwesimba.
- Kukurukurirana Kwakangwara: Inotsigira mapuroteni akaita seRS485, Wi-Fi, kana Ethernet yekutarisa.
- Remote Management: Inobvumira kutarisa uye kutonga kwehurongwa kure.

3. Kubatana pakati pePV Cable Selection uye Islanding Prevention
Kukosha kwePV Cables
PV tambo dzemhando yepamusoro dzinoita basa rakakosha mukuchengetedza kugadzikana kwehurongwa uye nekuona kunyatsoonekwa kwegridi mamiriro, izvo zvakakosha kune anti-islanding michina.
- Kufambisa Kwesimba Kunoshanda: Inoderedza madonhwe emagetsi uye kurasikirwa kwesimba, kuve nechokwadi chekuyerera kwesimba kune inverter.
- Kururama Kwechiratidzo: Inoderedza ruzha rwemagetsi uye kusiyanisa kusiyanisa, inovandudza iyo inverter kugona kuona kutadza kwegridi.
- Durability: Inovimbisa kuvimbika kwenguva refu mumamiriro akasiyana ezvakatipoteredza, kuchengetedza kushanda kwakadzikama.
4. InokurudzirwaPV Cables dzeGrid-Tied Systems
Pamusoro PV Cable Sarudzo

- Applications: Ground-yakaiswa uye padenga PV masisitimu.
- TUV PV1-F
- Features: Yakanakisa tembiricha kuramba (-40 ° C kusvika +90 ° C).
- Kuteerera: TÜV certification yemhando yepamusoro yekuchengetedza.
- Applications: Yakagoverwa PV masisitimu uye agrivoltaics.
- Armored PV Cables
- Features: Yakanatsiridza kuchengetedzwa kwemichina uye kusimba.
- Kuteerera: Inosangana neIEC 62930 uye EN 60228 zviyero.
- Applications: Industrial-scale PV masisitimu uye nharaunda dzakaomarara.
Parameter Kuenzanisa Tafura
Cable Model | Temperature Range | Certifications | Applications |
EN H1Z2Z2-K | -40°C kusvika +90°C | IEC 62930 | Denga uye utility PV masisitimu |
TUV PV1-F | -40°C kusvika +90°C | TÜV Certified | Distributed and hybrid systems |
Armored PV Cable | -40°C kusvika +125°C | IEC 62930, EN 60228 | Industrial PV kuiswa |
Danyang Winpower Wire uye Cable Mfg Co., Ltd.
Mugadziri wemidziyo yemagetsi uye zvekushandisa, zvigadzirwa zvikuru zvinosanganisira tambo dzemagetsi, wiring harnesses uye zvemagetsi zvinobatanidza. Inoshandiswa kune smart home system, photovoltaic system, simba rekuchengetedza masisitimu, uye magetsi emotokari masisitimu
Mhedziso uye Mazano
- Kunzwisisa Islanding: Islanding inoisa njodzi dzakakura kune chengetedzo, midziyo, uye kugadzikana kwegidhi, zvichidikanwa matanho ekudzivirira anoshanda.
- Kusarudza iyo Yakarurama Inverter: Sarudza ma inverters ane anti-islanding dziviriro, hunyanzvi hwepamusoro, uye kugona kutaurirana kwakasimba.
- Kukoshesa Matambo Emhando: Sarudza tambo dzePV dzine kusimba kwepamusoro, kuderera kwakadzika, uye kuita kwakavimbika kuti uve nechokwadi chekugadzikana kwehurongwa.
- Kuchengeta Nguva Dzose: Periodic kuongororwa kwePV system, kusanganisira inverters uye tambo, zvakakosha pakuvimbika kwenguva refu.
Nekunyatsosarudza izvo zvakanaka zvikamu uye kuchengetedza sisitimu, grid-yakasungirirwa PV kumisikidza inogona kuwana kwakaringana kuita uye kuchengetedzeka uku uchiomerera kune indasitiri zviyero.
