On load test ntawm hydrogenerator unit

1. Kev ntsuam xyuas cov load shedding thiab load shedding ntawm hydro generator units yuav tsum ua alternately.Tom qab chav tsev tau pib thauj khoom, kev ua haujlwm ntawm chav tsev thiab cov khoom siv hluav taws xob cuam tshuam yuav tsum raug kuaj xyuas.Yog tias tsis muaj qhov txawv txav, qhov kev kuaj tsis lees paub tuaj yeem ua tiav raws li cov txheej txheem system.

2. Thaum lub sij hawm nyob rau hauv lub load xeem ntawm cov dej turbine generator chav tsev, lub active load yuav tsum tau nce ib qib zuj zus, thiab kev khiav hauj lwm ntawm ib feem ntawm lub chav tsev thiab qhov taw qhia ntawm txhua qhov ntsuas yuav tsum tau soj ntsuam thiab kaw.Saib xyuas thiab ntsuas qhov kev vibration ntau thiab qhov loj ntawm chav tsev nyob rau hauv ntau yam kev thauj khoom, ntsuas lub siab pulsation tus nqi ntawm cov raj xa dej, saib xyuas kev ua haujlwm ntawm cov khoom siv dej qhia ntawm hydraulic turbine, thiab ua qhov kev sim yog tias tsim nyog.

3. Ua raws li kev tswj hwm kev ceev ntawm lub tsev nyob rau hauv load.Txheeb xyuas qhov ruaj khov ntawm kev tswj hwm chav tsev thiab kev sib koom ua ke hauv kev ceev thiab lub zog tswj hom.Rau kiv cua turbine, xyuas seb lub koom haum kev sib raug zoo ntawm kev ceev tswj system puas yog.

4. Ua kom nrawm nrawm nce thiab txo qhov ntsuas ntawm chav tsev.Raws li qhov chaw nyob, qhov ceev ceev ntawm chav tsev yuav tsum tsis txhob hloov ntau tshaj qhov ntsuas load, thiab cov txheej txheem hloov ntawm chav tsev ceev, volute dej siab, cua ntsawj ntshab siab pulsation, servomotor stroke thiab fais fab hloov yuav tsum tau sau cia.Nyob rau hauv tus txheej txheem ntawm load nce, xyuam xim rau saib thiab saib xyuas cov kev co ntawm lub tsev, thiab sau cov coj load, unit lub taub hau thiab lwm yam tsis.Yog tias chav tsev muaj kev co pom tseeb nyob rau hauv lub taub dej tam sim no, nws yuav tsum tau hla sai.

5. Ua excitation regulator test ntawm hydro generator unit nyob rau hauv load:
1) Yog tias ua tau, kho lub zog reactive ntawm lub tshuab hluav taws xob los ntawm xoom mus rau tus nqi ntsuas raws li tus qauv tsim, thaum lub zog ua haujlwm ntawm lub tshuab hluav taws xob yog 0%, 50% thiab 100% ntawm tus nqi ntsuas raws, thiab kev hloov kho yuav tsum yog. ruaj khov thiab tsis muaj runout.
2) Yog tias ua tau, ntsuas thiab ntsuas qhov ntsuas qhov ntsuas hluav taws xob ntawm lub tshuab hluav taws xob ntawm lub tshuab hluav taws xob, thiab cov yam ntxwv kev tswj hwm yuav tsum muaj qhov zoo linearity thiab ua tau raws li cov qauv tsim.
3) Yog tias ua tau, ntsuas thiab ntsuas qhov ntsuas qhov sib txawv ntawm qhov sib txawv ntawm lub tshuab hluav taws xob hydro, thiab nws cov nqi yuav tsum ua raws li cov qauv tsim.Thaum tsis muaj cov kev cai tsim, nws yuav tsum tsis txhob ntau tshaj 0.2%, -, 1% rau hom hluav taws xob thiab 1%, - 3% rau hom electromagnetic
4) Rau thyristor excitation regulator, ntau yam limiter thiab tiv thaiv kev ntsuam xyuas thiab teeb tsa yuav tsum tau ua raws.
5) Rau cov chav nyob nruab nrog lub zog ruaj khov system (PSS), 10% - 15% ntsuas load yuav tsum tau hloov tam sim ntawd, txwv tsis pub nws txoj haujlwm yuav raug cuam tshuam.
6. Thaum kho lub active load thiab reactive load ntawm chav tsev, nws yuav tsum tau nqa tawm nyob rau hauv lub zos tus tswv xeev thiab excitation ntaus ntawv feem, thiab ces tswj thiab kho los ntawm lub computer tswj system.
