Jinneng Project hauv Wuhan Rail Transit

Yam ntxwv ntawm Rail Transit Industry:

Kev sib haum xeeb hauv kev tsheb ciav hlau feem ntau yog los ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hauv lub tsheb traction fais fab mov, ua raws li DC fais fab mov chav tsev, teeb pom kev zoo, elevator, tso saib cov ntxaij vab tshaus, cua txias, kua dej, thiab lwm yam khoom siv. Cov kev sib haum xeeb no feem ntau suav nrog 5th, 7th, 11th, thiab 13th xaj, nrog qee qhov muaj nyob ntawm 3rd - xaj harmonics. Harmonics deplete reactive zog cia nyob rau hauv lub kaw lus, nce kab poob, cuam tshuam rau kev txhim khu kev qha kev lag luam ntawm relay tiv thaiv thiab tsis siv neeg tswj cov cuab yeej, txo cov kev ruaj ntseg ntawm cov khoom siv hluav taws xob, thiab ua rau electromagnetic cuam tshuam nrog kev sib txuas lus thiab signaling systems.

Tej teeb meem uas koj yuav ntsib:

1.Low power factor, rendering tsoos reactive hwj chim them nyiaj pab kiag li lawm tsis ua hauj lwm los yog nquag burnout.

2. Fluctuating loads.

3.High harmonic tam sim no distortion tus nqi, cuam tshuam kev lag luam txhim khu kev qha ntawm kev tiv thaiv relay thiab tsis siv neeg tswj cov cuab yeej.

4.Qhov hnyav peb-theem tsis txaus nyob rau hauv daim phiaj hluav taws xob.

Case Study:

Jinneng zog capacitors thiabactive zog limtau ua tiav kev ua haujlwm rau ib xyoos hauv cov cuab yeej siv chav ntawm Wuhan Rail Transit, ua kom pom kev ua tau zoo thiab ua kom muaj kev nyab xeeb ntawm kev khiav tsheb ciav hlau.

Peb cov kev daws teeb meem:

1. Siv JinnengAPF nquag lim dejkom txo tau cov ntsiab lus siab dua - xaj harmonics.

2. Ua haujlwm JinnengSVG dynamic reactive fais fab generatorskom dynamically muab reactive zog rau txhua theem ntawm lub system thaum ib txhij mitigating harmonics ntawm ntau yam kev txiav txim.

3.Ua kom muaj kev nyab xeeb kev nyab xeeb cov cuab yeej, tsim nrog cov khoom siv hluav taws xob tsim nyog thiab cov khoom siv reactor raws li lub cev muaj kev sib haum xeeb. Cov cuab yeej no txhim kho cov khoom siv hluav taws xob los ntawm kev siv hluav taws xob reactive, txhim kho lub zog zoo ntawm txoj kev tsheb ciav hlau hluav taws xob.

4.Cov nyiaj pab them nqi kev nyab xeeb dynamic tau txais ib txoj kev them nyiaj hybrid uas sib txuas nrog peb -theem ywj siab them nyiaj thiab peb-theem kev them nyiaj raws li qhov yuav tsum tau them nyiaj rau qhov system peb-theem imbalance.
