Mamiriro ekugadzira
Mamiriro emagetsi
Zvichienderana nehuwandu hwemagetsi ari muprojekiti iyi, kambani yedu iri kuronga kugadzira magetsi e18 MW seti dzejenareta yegesi+6 seti dze booster ne transformer skid (containerized tpye, kuti iwedzere kusvika 10 kV) + seti imwe ye 10 kV sub-section post + seti imwe ye step-down transformer skid. Nekupa seti gumi nesere dze 1MWgas generator dzakaiswa pa 6 box type transformer skids zvakateerana, 400 V voltage inowedzerwa kusvika 10 kV yozobatanidzwa kuenda ku 10 kV sub-section post, uye sub-section post inopa simba kune refrigeration compressor. Panguva imwe chete, chikamu chesimba remagetsi chinobuda kuenda ku step-down transformer skid, 400V electric energy inogoverwa ne step-down transformer skid.
Zvichienderana nesimba chairo reprojekiti, seti 1 ~ 2 dzemaseti ejenareta egasi e1MW (dzinozivikanwawo se 1000kw gasi genset） inogona kuvharwa, iyo inogona kuchinjwa kuti ishandiswe mu kugadziriswa kwejenareta kunotevera. Seti yesystem yekudzora chiteshi chiri kure inokurudzirwa papurojekiti iyi, iyo inogona kuona mashandiro chaiwo ejenareta iri mukamuri rekudzora repakati. Seti yegesi inoyerera yejenareta yegesi inoshandiswa pakushandisa kupisa kwemarara, uye unit ye1MW ine DN300 flue gas header neflange.
Imwe simba remagetsi rine simba guru rinopihwa nemushandisi i10KV±5% 50HZ±0.5HZ, sisitimu yewaya nhatu ine maphase matatu, uye nzvimbo isina simba haina kudzika. Kuvigwa kwakananga kwetambo dzemagetsi dzine simba guru dzinoiswa.
Chimiro chekugadzira
Bato B ndiro rine basa rekugadzira nzvimbo yemagetsi ye10KV/0.4KV uye sisitimu yemagetsi nekuparadzira yefekitori inonyungudutsa mvura (ine musoro wemagetsi unogamuchira kabhineti inopinda ye10KV semuganhu), rine basa rekugadzira madhayagiramu emagetsi ane voltage yepamusoro nepasi, madhayagiramu emagetsi ekudzora magetsi, uye dhayagiramu yeTerminal, dhayagiramu yekutarisa michina yemagetsi ine voltage yepamusoro nepasi, uye dhizaini yebhokisi rekushanda (koramu). Kugoverwa kwesimba refekitori yese, simba repombi huru yemagetsi yefekitori yekudzivirira moto, mwenje weveruzhinji wefekitori yese, sisitimu yemwenje yekuvaka, simba remagetsi redhiziri, uye mabhokisi ekuchengetedza (makabhineti) hazvisi mukati mehurongwa uhwu.
Nheyo dzekugadzira nekusarudza
(1) Midziyo yekudzora yemagetsi yefekitori iyi inonyungudutsa mvura inofanira kuedza kuva yakavimbika, yakachengeteka, yepamusoro uye iri nyore kushandisa zvichienderana nemamiriro ekugadzira uye zvinodiwa pakuita basa.
(2) Kudzora, kuyera, kuchengetedza uye chiratidzo chemota dzese nemidziyo yemagetsi zvinofanira kuiswa zvichienderana nemitemo yenyika yakakodzera.
(3) Sisitimu ye0.4KV iri mufekitori yakagadzirwa sedunhu rakapetwa kaviri.
(4) Midziyo yese yemagetsi inogadzirwa ine mabhokisi ekudzora mashandiro emunzvimbo (makabhineti). Chikamu chemidziyo yemagetsi yemunzvimbo inodzivirira kuputika chakagadzirwa zvichienderana neDⅡBT4, uye chikamu chayo chekudzivirira iIP65; chikamu chekudzivirira chekunze chemidziyo yemagetsi yekudzivirira munzvimbo dzisingaputike iIP54 Design, chikamu chekudzivirira chemidziyo yemagetsi yemumba chakagadzirwa zvichienderana neIP30.
(5) Kana mota dzepamusoro nedzepasi dzatanga kushanda, bhazi rinofanira kusvika pa85% yevoltage yakayerwa. Nechikonzero ichi, mota dzemagetsi mashoma dzine simba rakayerwa re75KW zvichikwira dzinofanirwa kutanga ne soft starter; mota huru ye refrigerant compressor inoshandisa high-voltage solid state Soft start device.
(6) Sisitimu yemagetsi ane simba guru inoshandisa mudziyo wekudzivirira wakabatana ne microcomputer kuti uite mabasa akadai sekudzivirira nerelay uye metering.
(7) Kushanda, kudzivirira uye simba rechiratidzo cheswitchgear ine simba guru rinoshandisa DC power supply yeDC220V, inobva paDC screen isina lead-acid battery, uye DC power supply inogovaniswa ne10KV system.
(8) Mamiriro ekushanda kwemidziyo yemagetsi yemidziyo yese inonyungudutsa mvura uye chiratidzo chemota ye30KW zvichikwira zvinopinda muDCS system kuti zvionekwe, uye michina yese yemagetsi yemidziyo yekugadzira inogona kutanga nekumira paDCS mukamuri rekudzora repakati, uye inogona zvakare kutanga nekumira munharaunda. Mabhatani ekumisa ekukurumidza emacompressor erefrigerant, macompressor egasi rekudyisa, mapombi emvura anotenderera, nezvimwewo. Anoiswa mukamuri rekudzora repakati.
(9) Mudziyo wekudzivirira wakazara we microcomputer we medium voltage system unogoverwa uye unoiswa pa switch cabinet yega yega, uye microcomputer background monitoring system inoiswa. Iyo 10KV system background monitoring system inogovaniswa ne 35KV background monitoring system, uye hapana setup yakasiyana inodiwa. Ziva kutarisa kwezviyero zvekushandisa simba re liquefaction plant, kutarisa kwemhando ye grid power supply, kudzora kure kwemidziyo, kuyerwa uye mabasa ealarm, manejimendi yemishumo, kuongorora mafambiro, nhamba, uye kurekodha kwese ma parameter emagetsi e liquefaction plant.
(10) Sisitimu ye10KV ine simba guru remagetsi rine simba remagetsi rinoita kuti pave nemagetsi anochinja-chinja (dynamic reactive power centralized compensation device) kuti pave nemagetsi anochinja-chinja (reactive power compensation) pamidziyo ine simba guru remagetsi. Mushure mekubhadhara, simba rebhazi rinoita kuti pave nemagetsi anochinja-chinja (high-voltage factor). Sisitimu yemagetsi anochinja-chinja ine simba risingabatike (non-contact switching reactive power compensation device) kuti pave nemagetsi anochinja-chinja (reactive power compensation) pabhazi re380V. Mushure mekubhadhara, simba rebhazi rinoita kuti pave nemagetsi anochinja-chinja (power factor) rinoita kuti pave nemagetsi anochinja-chinja (reactive power compensation).
