Kev tsim hluav taws xob tauj dua tshiab suav nrog lub hnub ci photovoltaic fais fab chaw nres tsheb, cua ua liaj ua teb, chaw nres tsheb hydropower, thiab lub zog cia fais fab nroj tsuag feem ntau nyob hauv thaj chaw qhib sab nraum zoov nrog cov xwm txheej hnyav thiab muaj kev pheej hmoo siab. SPDs tau siv dav hauv txhua qhov txuas tseem ceeb ntawm kev tsim hluav taws xob tauj dua tshiab, kev sib kis, thiab kab sib txuas, dhau los ua cov cuab yeej tiv thaiv rau cov phiaj xwm tshiab.

Hauv cov phiaj xwm photovoltaic fais fab, SPDs npog DC thiab AC lub zog hluav taws xob thiab cov teeb liab saib xyuas. DC SPDs tau teeb tsa hauv PV cov thawv sib txuas thiab inverter DC terminals los tiv thaiv lub hnub ci vaj huam sib luag arrays thiab DC kis kab los ntawm xob laim thiab induced surges. AC SPDs raug xa mus rau ntawm daim phiaj inverter- txuas cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob xa hluav taws xob kom txwv cov kab sib chaws- txuas dhau qhov hluav taws xob. Lub teeb liab SPDs tiv thaiv PV kev soj ntsuam thiab cov ntaub ntawv kis tau tus mob, ua kom muaj kev ruaj ntseg ntawm cov khoom siv saib xyuas ntse.

Hauv cov phiaj xwm cua fais fab, cov cua turbines thiab cov kiv cua sab nraum zoov tswj tau ntsib teeb meem loj heev vim lawv qhov siab - qhov siab siab. Hom 1 thiab Hom 2 ua ke SPDs tau nruab rau hauv cov cua turbine ntauwd fais fab faib cabins thiab kiv cua tswj txee kom tso tawm siab - xob laim hluav taws xob thiab tiv thaiv kiv cua tshuab hluav taws xob, cov khoom siv hloov pauv zaus, thiab PLC tswj cov tshuab los ntawm kev puas tsuaj overvoltage. Meanwhile, teeb liab SPDs tiv thaiv cua ceev sensors, yaw tswj systems, thiab tej thaj chaw deb teeb liab kis kab.

Hauv cov phiaj xwm dej, cov chaw nres tsheb hauv dej feem ntau ua rau hauv roob thiab cov av ntub nrog cov cua daj cua dub. SPDs yog siv rau hauv hydropower unit power distribution systems, generator control cabinets, and dam monitoring systems. Lawv tiv thaiv cov hluav taws xob hluav taws xob thiab hluav taws xob hloov hluav taws xob, tiv thaiv cov cuab yeej tsim hluav taws xob thiab cov cuab yeej tswj xyuas hydraulic thiab ua kom muaj zog ruaj khov ntawm hydropower units.

Nyob rau hauv electrochemical zog cia tej yaam num, lub zog cia roj teeb, BMS roj teeb tswj systems, thiab PCS fais fab mov tshuab yog rhiab heev rau voltage fluctuations. Tshwj xeeb los tiv thaiv -surge SPDs yog ntsia rau ntawm lub hwj chim inlet thiab tso zis terminals ntawm lub zog cia txee kom tsis txhob surge-vim lub roj teeb overcharge, tso tawm tsis ua hauj lwm, thiab kev tswj system tsis ua hauj lwm, ua kom muaj kev ruaj ntseg ntawm lub zog cia systems.

Daim ntawv thov ntawm SPDs hauv cov phiaj xwm hluav taws xob tauj dua tshiab daws qhov mob ntawm cov hluav taws xob hluav taws xob siab thiab cov khoom siv hluav taws xob tsis zoo hauv cov tshuab hluav taws xob tshiab, txo cov khoom siv tsis ua haujlwm thiab cov kev pheej hmoo ua haujlwm, txhim kho kev ruaj ntseg ntawm lub zog tshiab hluav taws xob tsim hluav taws xob thiab kab sib txuas, thiab txhawb kev nyab xeeb thiab muaj txiaj ntsig ntawm kev tsim hluav taws xob txuas ntxiv mus.
