Generator Chaw Tsim Tshuaj Qhia Txog Kev Nyab Xeeb ntawm Kev Ua Haujlwm Qib

Diesel generator teeb: los ntawm lub cav, lub tshuab hluav taws xob thiab tswj qhov system muaj pes tsawg leeg, thiaj li hu ua generator teeb. Diesel generator teeb yog ib yam khoom siv hluav taws xob uas siv lub tshuab hluav taws xob siv hluav taws xob ua tus thawj txav thiab tsav lub tshuab hluav taws xob synchronous los tsim hluav taws xob.Nws yog lub tshuab hluav taws xob tsim hluav taws xob nrog kev pib sai, kev ua haujlwm yooj yim thiab kev saib xyuas, kev nqis peev tsawg thiab muaj zog ib puag ncig adaptability.

Thaum lub tshuab hluav taws xob ua haujlwm ib txwm, nws muab lub zog ua haujlwm thiab rov ua haujlwm rau lub cev, thiab lub stator tam sim no lags qab lub davhlau ya nyob twg voltage los ntawm lub kaum sab xis.Lub xeev no hu ua post-operation.Thaum cov excitation tam sim no txo ​​qis, lub tshuab hluav taws xob hloov los ntawm kev muab lub zog reactive rau absorbing reactive zog los ntawm lub system, thiab lub stator tam sim no hloov los ntawm lagging mus rau lub generator davhlau ya nyob twg voltage los ntawm lub kaum sab xis.Lub xeev no hu ua kev ua haujlwm theem.Thaum lub tshuab hluav taws xob synchronous khiav ua ntej, qhov excitation tam sim no txo ​​qis heev, thiab lub tshuab hluav taws xob muaj peev xwm Eq txo qis raws li.Los ntawm p-power Angle kev sib raug zoo, thaum lub zog ua haujlwm tas li, lub hwj chim lub kaum sab xis yuav nce ntxiv, tag nrho cov kauj ruam fais fab sib piv yuav txo qis, thiab qhov ruaj khov ntawm lub tshuab hluav taws xob yuav txo qis.Nws qhov kev txwv tsis pub muaj feem cuam tshuam nrog luv luv Circuit Court piv ntawm lub tshuab hluav taws xob, sab nraud reactance, kev ua haujlwm ntawm kev ua haujlwm tsis siv neeg excitation thiab seb nws puas tau muab tso rau hauv kev ua haujlwm.

Piv nrog rau kev ua haujlwm tom qab, cov dej ntws tawm ntawm qhov kawg ntawm stator lub tshuab hluav taws xob nce hauv kev ua haujlwm siab heev.Tshwj xeeb tshaj yog loj generator kab load yog siab, qhov kawg magnetic to yog loj nyob rau hauv ib txwm ua hauj lwm, qhov kawg core siab yog hais txog qhov kub ntawm lub connector nce, nyob rau hauv ua ntej theem ua hauj lwm sib nqus to nce, kub nce yog intensified.Thaum lub sijhawm ua haujlwm ntawm cov hlau lead, lub davhlau ya nyob twg voltage ntawm lub tshuab hluav taws xob txo qis, thiab cov khoom siv hluav taws xob txo qis raws li.Yog tias nws tshaj 10%, nws yuav cuam tshuam rau kev ua haujlwm ntawm lub zog pabcuam.

Yog li ntawd, kev khiav hauj lwm qhov tob ntawm synchronous generator yuav tsum tau txiav txim los ntawm kev sim.Ntawd yog, ntau npaum li cas reactive zog tuaj yeem nqus tau los tswj qhov zoo li qub thiab kev ruaj ntseg ntawm lub cev, thiab qhov kub thiab txias ntawm txhua yam tsis pub dhau qhov txwv kom tau raws li qhov yuav tsum tau muaj voltage.

Kev puas tsuaj tshwm sim los ntawm theem ua haujlwm los ntawm cov chaw tsim khoom siv hluav taws xob:

1. Kev ua haujlwm ntawm lub tshuab hluav taws xob nce ntxiv yuav ua rau lub tshuab hluav taws xob tsis ruaj khov, uas yuav yooj yim ua rau lub tshuab hluav taws xob tsis ruaj khov thiab txawm tias qhov tshwm sim ntawm qhov system oscillation xwm txheej.

2. Txuas ntxiv txo qhov excitation tam sim no ntawm lub tshuab hluav taws xob thiab ua kom cov theem siab tshaj qhov tob ntawm lub tshuab hluav taws xob, uas yuav ua rau poob ntawm excitation tiv thaiv kev ua haujlwm ntawm lub tshuab hluav taws xob lossis kev ua haujlwm tsis ruaj khov ntawm lub tshuab hluav taws xob.

3. Thaum lub tshuab hluav taws xob khiav ua ntej, lub stator tam sim no nce thiab stator kub nce;Thaum lub tshuab hluav taws xob khiav ua ntej theem, qhov ntws tawm ntawm lub stator kawg nce, ua rau qhov kawg cua sov qhov hnyav tshaj plaws, thiab qhov kub ntawm lub stator coil ntawm lub tshuab hluav taws xob yuav nce ntxiv.

4. Thaum lub tshuab hluav taws xob khiav ua ntej ntawm theem, lub tshuab hluav taws xob hluav taws xob hluav taws xob txo qis, kom lub tsheb npav voltage 6KV txo.Lub high voltage voltage nrog undervoltage tiv thaiv yuav mus;Rau tag nrho cov khoom siv hluav taws xob ua haujlwm, lub tsheb npav voltage txo thiab qhov tam sim no nce, ua rau cov khoom siv cua sov.Kev ua haujlwm ntev yuav ua rau lub rwb thaiv tsev ntawm lub cuab yeej puas.
