Power system fing taka siam chhuah leh substation tam zel avang hian DC system enkawl hna thawh tur chu a harsa zual hle a, battery te fing taka enkawl leh enkawl a ngai ta hle a ni. Battery inverter grid-connected technology, operational power supply-a remote capacity testing design-a technology pawimawh ber pakhat a nih avangin, discharge energy chu grid-ah lumna siam lovin a luhtir leh thei a, chu chuan traditional heating load discharge avanga energy waste chu a pumpelh thei a ni. Hei hian carbon tlem, energy hmang tlem, leh boruak tichhe lo thil siam chhuah dan a tihlawhtling a, hei hi hmasawnna nghet tak siamna kawngah hian thil pawimawh tak a ni.
Engineering application-a operational power supply battery capacity testing atana scheme hman tlanglawn tak takte chu offline, online, leh integrated mode te a ni ber. Heng zingah hian online mode hi a system safety sang zawk avangin nasa takin an promote a, an hmang nasa hle a, hei hi capacity testing process hian load atanga a disconnect loh vang a ni a, retrofitting atan pawh a complexity a tlem hle bawk.
Operating state te hi standby floating charge, capacity discharge, leh constant current charge ah te then a ni. Heng state te hi system kalpui laiin an inthlak danglam a, capacity testing atan operating cycle kimchang tak an siam a ni.
Standby Floating Charge State
Floating charge state-ah chuan NC contactor CJ1/CJ2 chu a khar a, charge leh discharge switch K1/K2 chu a inhawng ta a ni. Battery hi online a ni a, DC system hian battery pack leh load-ah te power a pe vek a ni. Beisei loh taka power a tlakchhiat chuan battery pack hian load-ah direct-in power a pe thei a, hei hian power supply tihtawp loh a tichiang thei a ni.
Capacity Discharge State
Capacity discharge lai hian battery string pahnih hi dan angin an inthlak a. Entirnan, battery string 1 chu a discharge laiin battery group 2 chu float charging-ah a awm reng thung. NC contactor CJ1 a inhawng a, charge leh discharge switch K1 a khar a, PCS module chu a thawk thei bawk. Module hian battery string atanga DC power chu AC power ah a chantir a, grid ah a feed leh a, chu chuan online capacity testing a ti thei a ni. Discharge zawh veleh system chu constant current charging-ah a inthlak nghal vek a ni.
Constant Current Charge State
Capacity testing zawh a nih chuan battery te chu a discharge tawh lo va, PCS pawh a inverting tawh lo. NC contactor CJ1 leh charge leh discharge switch K1 te chu discharge lai ang bawkin an awm reng a ni. PCS hian rectification charging a tan a, grid atanga AC power chu DC power ah a chantir a, battery pre-charge nan a hmang thin. Chumi hnuah chuan constant current equalization leh trickle charging-ah a inthlak a, battery chu awlsam taka charge theih a ni.
A chunga kan sawi tak hian battery inverter grid-connected technology hmanga capacity testing system design leh kalpui dan a tarlang a ni. Hetiang method hi industry siamtute chuan an hmang nasa hle a ni. Entirnan, DFUN hian a design a remote online capacity testing solution , hmun darh zau tak takte chu hla tak atanga centralized control theihna, hun, thawhrimna leh senso a humhim thei a ni.
Capacity testing function bakah hian he remote online capacity testing solution hian real-time battery monitoring leh battery activation function te a keng tel bawk a, 24/7 real-time remote battery monitoring leh maintenance a tihlawhtling tak zet a ni.
