Dab tsi yog Qhov Kev Tiv Thaiv Qhov Zoo ntawm Silent Diesel Generator Sets

Silent genset tuaj yeem txo cov suab nrov thiab nrov heev hauv cov tsev nyob, tsev kho mob thiab lwm qhov chaw.Nyob rau hauv xyoo tas los no, kev ua lag luam rau cov tshuab hluav taws xob uas ntsiag to tau dhau los ua qhov xav tau ntau dua.Cia peb saib ntawm cov twj tso kua mis diesel generators hauv qab no.Kaum qhov kev tiv thaiv zoo.

1. Lub tshuab hluav taws xob uas ntsiag to tsis muaj kev tiv thaiv kev zoo siab.

Kev tiv thaiv kev poob-ntawm-excitation yog siv los ua kev tiv thaiv kev poob-ntawm-excitation txhaum thaum lub zog tam sim no ntawm lub tshuab hluav taws xob poob qis lossis ploj tag.Nws yog tsim los ntawm cov txheej txheem xws li excitation low voltage Ufd(P), system low voltage, static stability impedance, TV disconnection uas nws teeb tsa tus nqi hloov pauv nrog lub zog nquag, uas ua rau kev taw qhia thiab de-excitation feem.Ob qhov excitation low voltage Ufd(P) criterion thiab static stability impedance criterion muaj feem xyuam rau cov ciam teb ruaj khov zoo li qub, uas tuaj yeem tshawb xyuas seb lub tshuab hluav taws xob puas poob nws qhov kev ruaj ntseg zoo li qub vim tsis muaj excitation.Lub static stability impedance criterion ua nyob rau hauv static stability ciam teb tom qab poob ntawm hlau nplaum.

2. Mute diesel generator overexcitation tiv thaiv.

Kev tiv thaiv overexcitation yog ib qho kev tiv thaiv uas qhia txog kev ua haujlwm ntau dhau ntawm cov hlau nplaum uas tshwm sim los ntawm lub tshuab hluav taws xob txo qis lossis qhov hluav taws xob ntau dhau.Kev tiv thaiv overexcitation tau muab faib ua qhov siab thiab qis.Qhov teeb tsa qis xa cov teeb liab tom qab qhov ncua sij hawm ntawm 5s thiab txo qhov excitation voltage (kev ua haujlwm ntawm kev txo qhov excitation voltage thiab excitation tam sim no tsis siv ib ntus), thiab qhov chaw siab ua haujlwm hauv de-loading tom qab lub sijhawm txwv.Demagnetization.Qhov kev txwv sab saud ntawm lub sijhawm ncua sijhawm yog 5 vib nas this, thiab qis dua yog 200 vib nas this.

3. Silent diesel generator stator grounding tiv thaiv.

Generator stator grounding tiv thaiv yog siv los ua lub tshuab hluav taws xob stator ib-theem grounding txhaum tiv thaiv.Nws muaj ob ntu: lub hauv paus xoom kab ke voltage ib feem thiab qhov thib peb harmonic voltage.Qhov tseem ceeb xoom kab ke voltage tiv thaiv ib-theem stator winding nyob rau hauv 95% cheeb tsam ntawm lub tshuab kawg mus rau lub tshuab tw.Kev ua txhaum hauv av yog tsim los ntawm kev xav txog lub hauv paus ntsiab lus ntawm xoom-sequence voltage ntawm lub tshuab hluav taws xob kawg, uas ua rau demagnetization tom qab lub sijhawm txwv ntawm t1 (3s);qhov thib peb harmonic voltage tiv thaiv ib leeg-theem grounding txhaum ntawm stator winding los ntawm lub tshuab hluav taws xob tus Tsov tus tw mus rau 30% ntawm lub tshuab hluav taws xob kawg.Qhov nruab nrab ntawm lub tshuab hluav taws xob thiab lub hauv paus ntsiab lus thib peb ntawm lub tshuab hluav taws xob kawg yog tsim, thiab ua raws li lub teeb liab tom qab lub sijhawm txwv ntawm t2 (5s).Qhov ob yog 100% stator grounding tiv thaiv.Kev tiv thaiv yog nruab nrog PT disconnection xauv.

4. Silent diesel generator stator tig tiv thaiv.

Kev tiv thaiv yog tsim los ntawm longitudinal zero sequence voltage thiab qhov tsis zoo ib ntus kev taw qhia cov txheej txheem ntawm qhov txhaum.PT disconnection thaiv kev ntsuas yog tsim los ua qhov kev tiv thaiv tseem ceeb rau lub tshuab hluav taws xob sab hauv thiab theem luv Circuit Court thiab qhib vuam ntawm stator winding.Qhov tsis zoo ib ntus kev taw qhia cov txheej txheem ntawm qhov kev ua txhaum yog dhau Kev Tshawb xyuas qhov tsis zoo-ib ntu lub zog ntws tawm ntawm lub tshuab hluav taws xob kom paub txog qhov ntev xoom-ib ntus qhov ntsuas hluav taws xob yog pom tau los ntawm kev kuaj xyuas qhov ntev 3UO tso tawm los ntawm 3PT qhib delta winding uas nruab nrab taw tes ncaj qha txuas mus rau qhov nruab nrab ntawm lub tshuab hluav taws xob tab sis tsis muaj av.Qhov kev tiv thaiv yog nyob ntawm qhov nres.

5. Lub tshuab hluav taws xob uas ntsiag to tsis muaj kev tiv thaiv.

Kev tiv thaiv siv lub ntsiab lus peb-impedance txhawm rau txheeb xyuas tus lej ntawm cov zawv zawg ncej thiab txiav txim siab qhov chaw ntawm qhov chaw oscillation los ntawm kev hloov pauv ntawm impedance trajectory.Nyob rau hauv cov ntaub ntawv ntawm short-circuit txhaum, system oscillation, voltage Circuit Court disconnection, thiab lwm yam., kev tiv thaiv yuav tsis malfunction.Kev tiv thaiv feem ntau ua rau lub teeb liab;thaum lub chaw oscillation nyob rau hauv lub tshuab hluav taws xob-transformer pab pawg, qhov kev tiv thaiv theem kuv pib thiab xa cov lus txib mus los ntawm t1 (0.5s), uas ua rau de-excitation;thaum lub chaw oscillation nyob sab nraum lub tshuab hluav taws xob-transformer pab pawg, kev tiv thaiv Qhov pib ntawm ntu II yog teeb liab ntawm t2(2s).Cov cuab yeej tiv thaiv tau nruab nrog cov cuab yeej thaiv tam sim no los xyuas kom meej tias qhov tam sim no tsis tshaj qhov ntsuas tawm ntawm cov kauj ruam tawg tam sim no ntawm Circuit Court breaker thaum lub Circuit Court breaker tawm.

6. Tsawg zaus cumulative tiv thaiv rau ntsiag to diesel generators.

Cov kev tiv thaiv tsawg-zaus tsub zuj zuj reacts mus rau cumulative nyhuv ntawm qhov txo zaus ntawm qhov system ntawm chav turbine.Cov kev tiv thaiv muaj ib tug rhiab zaus relay thiab txee, thiab yog thaiv los ntawm lub auxiliary kev sib cuag ntawm lub qhov hluav taws xob Circuit Court breaker (uas yog, lub low-frequency accumululation tiv thaiv kuj tawm thaum lub generator tawm hauj lwm), thiab cumulative system zaus yog tsawg thaum. qhov zaus yog teem rau ntawm 47.5 Hz, thaum lub sij hawm sau mus txog qhov teeb meem ntawm 3000 vib nas this, lub teeb liab yuav raug xa tom qab ncua 30 vib nas this.Cov cuab yeej tuaj yeem saib xyuas hauv lub sijhawm tiag tiag thaum lub sijhawm ua haujlwm: tus nqi ruaj khov, zaus f thiab cov sijhawm sib sau ua ke.

7. Silent diesel generator excitation circuit overload tiv thaiv.

Excitation Circuit Court overload tiv thaiv yog siv los tiv thaiv lub rotor excitation Circuit Court los ntawm overcurrent los yog overload.Nws txuas rau hauv peb-theem hom thiab muaj ob ntu: lub sijhawm tseeb thiab lub sijhawm hloov pauv.Kev khiav hauj lwm tam sim no ntawm lub sijhawm kawg yog teem raws li qhov xwm txheej uas nws tuaj yeem ntseeg tau rov qab los ntawm qhov siab tshaj plaws tam sim no ntawm kev ua haujlwm ib txwm muaj.Tom qab lub sij hawm txwv t1 (5s), nws ua rau lub teeb liab thiab txo cov excitation tam sim no (kev ua haujlwm ntawm kev txo cov excitation tam sim no tsis siv);Cov yam ntxwv ntawm kev ua haujlwm ntawm lub sijhawm hloov pauv yog raws li lub tshuab hluav taws xob Lub peev xwm dhau ntawm qhov excitation winding yog txiav txim siab, thiab kev tiv thaiv kev ua haujlwm yog nyob rau hauv de-energization thiab de-excitation.Lub sijhawm txwv sab saud ntawm lub sijhawm hloov pauv yog 10 vib nas this.

8. Ib-point grounding tiv thaiv rau lub rotor ntawm ntsiag to diesel generator.

Lub tshuab hluav taws xob rotor ib-point grounding tiv thaiv yog siv los cuam tshuam qhov ib-point hauv av txhaum ntawm thegenerator rotor circuit.Kev tiv thaiv txais yuav txoj cai ping-pong switching.Qhov zoo thiab qhov tsis zoo hauv av voltages ntawm lub rotor Circuit Court yog ua piv txwv nyob rau hauv lem, thiab lub rotor grounding kuj yog xam nyob rau hauv lub sij hawm los ntawm kev daws ob qhov sib txawv hauv av voj voog sib npaug.Thiab grounding txoj hauj lwm.Kev tiv thaiv yuav ua rau lub teeb liab tom qab ncua 2 vib nas this.

9. Symmetrical overload tiv thaiv rau ntsiag to diesel generators.

Cov cuab yeej tiv thaiv yog tsim los ntawm ob ntu: lub sijhawm tseeb thiab lub sijhawm hloov pauv.Lub sijhawm tshwj xeeb ua haujlwm ntawm lub teeb liab tom qab lub sijhawm txwv ntawm 5 vib nas this.Cov yam ntxwv ntawm lub sij hawm hloov pauv yog txiav txim siab raws li lub tshuab hluav taws xob lub peev xwm los tiv thaiv cov overload tam sim no, thiab qhov kev txiav txim yog nyob rau hauv de-loading.Cov cuab yeej tiv thaiv tuaj yeem cuam tshuam cov txheej txheem ntawm cov cua sov ntawm lub tshuab hluav taws xob stator.

10. Tsis zoo ib ntus dhau kev tiv thaiv rau cov tshuab hluav taws xob uas ntsiag to.

Cov cuab yeej tiv thaiv yog tsim los ntawm ob ntu: lub sijhawm tseeb thiab lub sijhawm hloov pauv.Lub sij hawm txwv txiav txim tam sim no yog teem raws li lub sij hawm ntev tso cai tsis zoo ib ntus tam sim no tus nqi ntawm cov lub tshuab hluav taws xob thiab tus nqi tam sim no uas zam qhov tsis sib xws ntawm qhov tsis zoo ib ntus tam sim no lim nyob rau hauv qhov siab tshaj plaws load.Qhov thib ob ua rau lub teeb liab.Cov yam ntxwv ntawm lub sijhawm hloov pauv yog txiav txim siab raws li lub peev xwm ntawm lub tshuab hluav taws xob los tiv thaiv qhov tsis zoo raws li tam sim no, thiab qhov kev txiav txim yog nyob rau hauv de-excitation thiab de-excitation.
