Diad konteksto na maples ya iyaaligwas na modernon industriya na kuryente na dagem, lalo la ed saray atagey a -power onshore tan offshore wind turbines, say yegyeg so nagmaliw ya sakey ed saray manunan sengegan ya mangaapekta ed kaligenan, karukey na bilay, pakawalaan na kuryente, tan gastos ed operasyon tan panmintina na turbina na dagem. Legan ya ondarakel so katagey na hub na wind turbine, ondarakel so karukey na blade, tan ondarakel so kapasidad na sakey a unit, saray problema a singa say wind vibration, tower resonance, blade swawing, transmission chain vibration, tan foundation vibration ya aarapen na saray wind turbine legan na operasyon et lalon onkakasil.
Kanian, akin et nakaukolan so vibration damper parad operasyon na kuryente na dagem? Saray maksil a dagem, maksil a dagem, maksil a dagem, tan say tower shadow effect so pansengegan na panapanaon ya pandurumaan na saray payak, a pansengegan na pan-flap tan pan-oscillation na blade, a manresulta ed hub, main shaft, gearbox, tan tower, a manresulta ed tuloytuloy a panag-yegyeg. Say impeller mass agbalance, say main shaft misalignment, say bearing wear, tan say gearbox gear meshing impacts et mamapawala na high-frequency vibrations, ya manunan sengegan na pakaandi na transmission chain. Say tori et sakey a maimpis tan nababanat ya istruktura ya walaan na abeban first-order natural frequency, kanian mainomay itan ya onkiwas ed impeller rotation frequency tan blade passage frequency. No nagawa so resonance, say vibration amplitude et onlaknab a maong, ya mamepeligro ed kaligenan na istruktura.
Anto ray peligro ya pansengegan na yegyeg ed saray turbina na dagem? Diad tuloytuloy ya panag-yegyeg, say fatigue life na saray gearbox, bearing, main shaft, tan yaw systems et napatikeyan a maong, tan say failure rate et ondarakel a maong. Say yegyeg et nayarin pansengegan na pakalukas na tower flange bolts tan main frame bolts, tan no grabe so kaso, nayarin ompatnag iray fatigue cracks ed saray welds. Say panlampas ed limitasyon na yegyeg et mamawala na bawas na karga na manunan sistema na kontrol, limitasyon na kapeles, tan proteksion ed pakasara, ya direktan mamawas ed panaon tan output na panagpawala na kuryente. Saray ag-inkayadyari na vibration- et manlalapud masulok ya 50% ed amin ya ag-inkayadyari na wind turbine, tan say panmintina ed atagey-altitude tan say gastos ed operasyon tan panmintina ed dayat et atagey a tuloy. Say andukey a resonance odino arawrawin yegyeg et nayarin pansengegan na pan-crack na blade, deformation na tower, pakaderal na pundasyon, tan anggan saray seryoson aksidente ed kaligenan.
Sayan artikulo so mangipapaamta ed pangiyaplika na vibration dampers ed saray blade na wind turbine. Saray blades so sankagrabian ya onyegyeg ya kabiangan, ya manunan mangipapatnag na panag-flap, panag-oscill, panag-flutter, tan panag-icing- ya ag balansin panag-yegyeg. Saray internally tuned mass dampers, ya aka-install ed 20%-40% na karukey na blade, et manguusar na mass block, springs, tan damping structure pian maka-tune ed vibration frequency na blade, ya epektibon mamatunda ed first- tan komaduan-order ya oscillations tan flapping vibrations, ya mamapaabeba ed fague ed panaon na blade, tan onlaknab bilay.
Say pangusar na vibration dampers et mamapaabeba na blade vibration na 30%-60%, mamapaabeba na blade fatigue damage na masulok ya 40%, mamapaabeba ed posibilidad na pan-crack tan debonding na blade, tan mamalemew ed ag-inkabalanse ya epekto na icing vibration.
Say industriya na wind power et kaslakan ya manguusar na nanduruman klase tan prinsipyo na pantratrabaho na vibration dampers. Say sankalaknaban ya uusaren et say tuned mass damper, ya tugyopen na mass block, spring, tan damper. Say frequency et aka-tune ed manunan frequency na yegyeg na wind turbine. No walay yegyeg, say mass block et onkiwas ed kabaliktaran ya direksion pian mangupot na enerhiya. Walaan itan na napanmatalkan ya istruktura, malet ya epekto, tan malaknab ya pakausaran.
Saray offshore wind turbines et mankikimey ed saray kaliberliber ya mas mairap nen saray onshore turbines. Kanian, say vibration damper et nepeg ya makasumpal ed atagey ya corrosion resistance requirements, kaiba lay hot-dip galvanizing, 316L stainless steel, Dacromet coating, salt spray testing ed loob na masulok ya 1000 oras, tan malet ya operasyon ed temperaturan manlapud -40℃anggad 80 degree. Say gastos ed panmintina ed dayat et atagey a tuloy, kanian kaukolan so desinyo ya andukey so bilay to. Say hydraulic damper et nepeg met ya adesinyo pian ag-onlelereg so larak ya nayarin mandutak ed dayat.
Anto ray praktikal ya gunggona na saray wind farm no mangusar na Vibration Damper?
Say indaak na pakawalaan na kuryente, say inmabeba ya yegyeg- so sengegan na limitasyon na kuryente tan panaon ya ag-onkikiwas, malet ya operasyon ed saray magulon dagem, tan say indaak na pakawalaan na kuryente ya 2%-8%; pinalaknab so bilay na saray manunan kabiangan, ya say bilay na blade et inmaligwas na 20%-40%, say bilay na gearbox et inmaligwas na 30%-50%, tan say tower fatigue damage et inmaligwas na 30%-60%; baleg so nabawasan ya gastos ed operasyon tan panmintina, mas daiset so operasyon ed panmintina ed atagey a pasen, mas daiset so pansalat na gearbox tan bearing, ya makatipid na nilibon anggad samplon libon dolyar na US kada offshore wind turbine kada taon; pinaaligwas so inkalapagan ya kaligenan na turbina, napaliisan so resonance, napaaligwas so survivalability ed silong na bagyo, yegyeg, tan daluyon, tan nabawasan so peligro na pan-looning na bolt tan paka-crack na istruktura; nabawasan so ungol, tan nabawasan so ungol na dagem tan istruktura, ya makasumpal ed saray kakaukolanen ed proteksion na kaliberliber tan makatulong ed pakagamor na proyekto.
