There are rum\u00adbling and hiss\u00ading nois\u00ades in the pro\u00adduc\u00adtion hall in Unter\u00adwellen\u00adborn, Thuringia where enor\u00admous forces are at work when the 1,250-degree, glow\u00ading red steel blocks are dri\u00adven back and forth through the rolling mill until they have the desired thick\u00adness and shape. Stahlw\u00aderk Th\u00fcrin\u00adgen GmbH (SWT) pro\u00adduces more than 800,000 tons of steel per year, which is used world\u00adwide in the con\u00adstruc\u00adtion indus\u00adtry, for bridges and rail\u00adways, but also in off\u00adshore wind farms. To meet the var\u00adi\u00adous require\u00adments, SWT has over 250 dif\u00adfer\u00adent pro\ufb01les in its range, all of which are made from 100-per\u00adcent recy\u00adcled scrap.<\/p>\n\n\n\n

The large dri\u00adves that pro\u00adpel the steel through the rollers per\u00adform heavy-duty work, which also affects the pow\u00ader grid\u2014at least if SWT does not take pre\u00adven\u00adta\u00adtive action. Prob\u00adlems may arise since the motors need sub\u00adstan\u00adtial reac\u00adtive pow\u00ader to man\u00adage ongo\u00ading accel\u00ader\u00ada\u00adtion, brak\u00ading, and changes in direc\u00adtion. Added to this are har\u00admon\u00adics gen\u00ader\u00adat\u00aded by the oper\u00ada\u00adtion of pow\u00ader\u00adful speed-con\u00adtrolled rolling mill dri\u00adves.<\/p>\n\n\n\n

Since too much reac\u00adtive pow\u00ader and har\u00admon\u00adics over\u00adload the pow\u00ader grid and make it unsta\u00adble, ener\u00adgy sup\u00adpli\u00aders set lim\u00adits that large indus\u00adtri\u00adal con\u00adsumers are not allowed to exceed, with vio\u00adla\u00adtions result\u00ading in con\u00adsid\u00ader\u00adable costs. Com\u00adpa\u00adnies such as SWT must there\u00adfore take mea\u00adsures to ensure that they do not feed too much of these dis\u00adrup\u00adtive fac\u00adtors into the grid. Until now, SWT has relied on an SVC (sta\u00adt\u00adic var com\u00adpen\u00adsator) sys\u00adtem with \ufb01lter cir\u00adcuits and a thyris\u00adtor-con\u00adtrolled reac\u00adtor (TCR) to pro\u00advide capac\u00adi\u00adtive and induc\u00adtive reac\u00adtive pow\u00ader, and \ufb01lter out har\u00admon\u00adics. To remain pre\u00adpared for the future, inno\u00adv\u00ada\u00adtive solu\u00adtions were con\u00adsid\u00adered to bet\u00adter meet upcom\u00ading require\u00adments.<\/p>\n\n\n\n

Efficient STATCOM system<\/h2>\n\n\n\n

When col\u00adleagues from MR\u2019s Pow\u00ader Qual\u00adi\u00adty Projects depart\u00adment pre\u00adsent\u00aded a con\u00adcept for a new STATCOM sys\u00adtem at SWT, it came at just the right time. STATCOM (sta\u00adt\u00adic syn\u00adchro\u00adnous com\u00adpen\u00adsator) is a sys\u00adtem for dynam\u00adic reac\u00adtive pow\u00ader con\u00adtrol in elec\u00adtri\u00adcal pow\u00ader trans\u00admis\u00adsion sys\u00adtems. It belongs to the FACTS (\ufb02ex\u00adi\u00adble AC trans\u00admis\u00adsion) fam\u00adi\u00adly of sys\u00adtems or plants which were devel\u00adoped to improve the sta\u00adbil\u00adi\u00adty, effi\u00adcien\u00adcy, and \ufb02ex\u00adi\u00adbil\u00adi\u00adty of pow\u00ader grids. The main advan\u00adtage of STATCOM sys\u00adtems is that they react much faster than an SVC plant and do not require \ufb01lter cir\u00adcuits, which results in sig\u00adni\ufb01\u00adcant\u00adly few\u00ader loss\u00ades.

This is because prob\u00adlems such as those encoun\u00adtered at the SWT steel\u00adworks arise wher\u00adev\u00ader ener\u00adgy is dynam\u00adi\u00adcal\u00adly con\u00advert\u00aded.\u201d SWT is the \ufb01rst cus\u00adtomer to use this solu\u00adtion, with the new sys\u00adtem sched\u00aduled to go into oper\u00ada\u00adtion in mid-2026.

Mining<\/h4>\n\n\n\n

Many mines, such as those for cop\u00adper min\u00ading, are locat\u00aded in remote regions with long trans\u00admis\u00adsion lines that are sus\u00adcep\u00adti\u00adble to volt\u00adage fluc\u00adtu\u00ada\u00adtions. In addi\u00adtion, the large machines (con\u00advey\u00ador sys\u00adtems, crush\u00aders, mills) require a lot of reac\u00adtive pow\u00ader. STATCOM com\u00adpen\u00adsates for this.<\/p>\n\n\n\n
