Ho kenya motlakase oa motlakase o tlase haholo - Karolo ea 7-712: Litlhoko tsa lits'ebetso kapa libaka tse ikhethileng - Sisteme ea phepelo ea motlakase ea Solar photovoltaic (PV)

Khomishene ea Machabeng ea Electrotechnical (IEC) e phatlalalitse IEC 60364-7-712: 2017 bakeng sa "Mechini e tlase ea motlakase o tlase - Karolo ea 7-712: Litlhoko tsa lisebelisoa tse khethehileng kapa libaka - Sistimi ea phepelo ea motlakase ea Solar photovoltaic (PV)".

Tlhaloso: “IEC 60364-7-712: 2017 e sebetsa ho kenyeng motlakase oa sistimi ea PV e reretsoeng ho fana ka tsohle kapa karolo ea kopo. Lisebelisoa tsa tlhomamiso ea PV, joalo ka thepa efe kapa efe ea lisebelisoa, li sebetsoa feela ha feela khetho ea eona le ts'ebeliso ea eona ho kenngoe. Khatiso ena e ncha e kenyelletsa lintlafatso tse kholo le katoloso, ho nahanoa boiphihlelo bo fumanoeng ho aheng le ts'ebetsong ea lits'ebetso tsa PV, le tsoelo-pele e entsoeng ho theknoloji, ho tloha ha khatiso ea pele ea standard ena e phatlalatsoa. ​​”

Boholo:

Karolo ena ea IEC 60364 e sebetsa ho kenyeng motlakase oa sistimi ea PV e reretsoeng ho fana ka tsohle kapa karolo ea tlhomamiso.

Lisebelisoa tsa tlhomamiso ea PV, joalo ka thepa efe kapa efe ea lisebelisoa, e sebetsoa ka eona feela ho fihlela khetho ea eona le ts'ebeliso ea eona ho kenngeng.

Sesebelisoa sa PV se qala ho tsoa ho module ea PV kapa li-module tsa PV tse hokahantsoeng ka tatellano le likhoele tsa tsona, tse fanoeng ke moetsi oa module ea PV, ho fihlela ts'ebetsong ea mosebelisi kapa ntlha ea phepelo ea utility (ntlha ea ho kopanya ho tloaelehileng).

Litlhoko tsa tokomane ena lia sebetsa ho

• Lisebelisoa tsa PV tse sa hokahanngoang le sistimi ea kabo ea motlakase ho sechaba,
• Lisebelisoa tsa PV ka mokhoa o ts'oanang le sistimi ea kabo ea motlakase ho sechaba,
• Lisebelisoa tsa PV joalo ka mokhoa o mong oa sistimi ea kabo ea motlakase ho sechaba,
• metsoako e loketseng ea tse kaholimo. Tokomane ena ha e koahele litlhoko tse khethehileng tsa ho kenya libeteri kapa mekhoa e meng ea polokelo ea matla.

TLHOKOMELISO 1 Litlhoko tse ling bakeng sa lits'ebetso tsa PV tse nang le bokhoni ba ho boloka betri ka lehlakoreng la DC li ntse li hlahlojoa.

TLHOKOMELISO 2 Tokomane ena e akaretsa litlhoko tsa ts'ireletso ea li-PV tse hlahisang ka lebaka la ts'ebeliso ea libeteri lits'ebetsong tsa PV.

Bakeng sa lits'ebetso tse sebelisang li-converter tsa DC-DC, ho ka hlokahala litlhoko tse ling mabapi le boemo ba motlakase le ba hajoale, switching le lisebelisoa tse sireletsang. Litlhoko tsena li ntse li hlahlojoa.

Morero oa tokomane ena ke ho sebetsana le litlhokahalo tsa polokeho ea moralo tse hlahang ho litšobotsi tse ikhethang tsa lits'ebetso tsa PV Litsamaiso tsa DC, le li-arrows tsa PV ka ho khetheha, li baka likotsi ho kenyelletsa tse tsoang mehahong e tloaelehileng ea motlakase oa AC, ho kenyelletsa le bokhoni ba ho hlahisa le ho boloka li-arcs tsa motlakase ka maqhubu a seng maholo ho feta maqhubu a tloaelehileng a ts'ebetso.

Ka har'a mechini e hokahantsoeng ea PV litlhokahalo tsa polokeho ea tokomane ena li its'etleha haholo ho PCE e amanang le PV e tsamaellanang le litlhoko tsa IEC 62109-1 le IEC 62109-2.
