H<\/span>uman\u00adi\u00adty wants to move more and more ener\u00adgy simul\u00adta\u00adne\u00adous\u00adly, which requires large high-per\u00adfor\u00admance trans\u00adform\u00aders of all types: those for HVDC trans\u00admis\u00adsion across entire coun\u00adtries, those for many indus\u00adtri\u00adal appli\u00adca\u00adtions, such as elec\u00adtric arc fur\u00adnaces for steel\u00admak\u00ading, or vari\u00adable shunt reac\u00adtors for reac\u00adtive pow\u00ader com\u00adpen\u00adsa\u00adtion. For Ampri\u00adon, this means pow\u00ader\u00adful phase-shifter trans\u00adform\u00aders or, more pre\u00adcise\u00adly, the most pow\u00ader\u00adful phase shifter ever.
\n<\/p>\n

A Emergency Call ist recieved<\/h2>\n

Ampri\u00adon is one of four trans\u00admis\u00adsion grid oper\u00ada\u00adtors in Ger\u00admany. The cat\u00ada\u00adlyst for build\u00ading the giant phase shifter, and the asso\u00adci\u00adat\u00aded ground\u00adbreak\u00ading devel\u00adop\u00adments, was an emer\u00adgency call. A few years ago, the Ger\u00adman Fed\u00ader\u00adal Net\u00adwork Agency con\u00adtact\u00aded Ampri\u00adon with the request to install high-end phase shifters at over\u00adloaded nodes as quick\u00adly as pos\u00adsi\u00adble. Because a study had con\u00adfirmed what many sus\u00adpect\u00aded at the time: Expan\u00adsion of the pow\u00ader grids in Ger\u00admany is not keep\u00ading pace with the increased sup\u00adply of renew\u00adable ener\u00adgy.<\/p>\n

At dimen\u00adsions of 30 x 26 x 11 meters, this device is as large as five sin\u00adgle-fam\u00adi\u00adly hous\u00ades, and it has a weight of 935 met\u00adric tons\u2014this gigan\u00adtic phase shifter will pay for<\/figcaption><\/figure>\n

Rein\u00adhard Bradt, who is in charge of grid projects at Ampri\u00adon, goes into more detail. \u201cThis can result in indi\u00advid\u00adual max\u00adi\u00admum-volt\u00adage trans\u00admis\u00adsion lines becom\u00ading over\u00adloaded when ener\u00adgy is trans\u00adferred from off\u00adshore wind parks in north\u00adern Ger\u00admany, for exam\u00adple, to the con\u00adsump\u00adtion cen\u00adters in south\u00adern Ger\u00admany.\u201d Gigan\u00adtic phase shifters will help keep the grid durable and pow\u00ader\u00adful, on an ad hoc basis, until grid expan\u00adsion catch\u00ades up by 2030. How\u00adev\u00ader, two con\u00addi\u00adtions must be met to avoid dot\u00adting the land\u00adscape with expen\u00adsive emer\u00adgency solu\u00adtions: \u201cInvest\u00adments should amor\u00adtize with\u00adin three years and should be sus\u00adtain\u00adable.\u201d<\/p>\n

Turbo for the VACUTAP\u00ae<\/h2>\n

A phase shifter is like a two-way valve for the grid that deter\u00admines whether the cur\u00adrent flows from left to right or from right to left. Using this device, grid oper\u00ada\u00adtors can relieve the load on lines with\u00adout hav\u00ading to inter\u00advene in pow\u00ader con\u00adsump\u00adtion or pro\u00adduc\u00adtion, since that would result in hefty redis\u00adpatch\u00ading fees. While a phase shifter can\u00adnot increase the over\u00adall trans\u00admis\u00adsion capac\u00adi\u00adty of the grid, it can move the load with\u00adin the grid to ensure bet\u00adter uti\u00adliza\u00adtion until expan\u00adsion can increase the grid\u2019s over\u00adall trans\u00admis\u00adsion capac\u00adi\u00adty.<\/p>\n

Ampri\u00adon com\u00admis\u00adsioned Siemens Ener\u00adgy with the con\u00adstruc\u00adtion of the first mega phase shifter. It will boast the fol\u00adlow\u00ading fea\u00adtures: 400 kilo\u00advolt rat\u00aded volt\u00adage, 2,000 mega\u00advolt-ampere through\u00adput capac\u00adi\u00adty and 2,992 ampere rat\u00aded cur\u00adrent. But what still wasn\u2019t clear was how oper\u00ada\u00adtors should per\u00adform switch\u00ading oper\u00ada\u00adtions when such loads are present.<\/p>\n

Bradt con\u00adsid\u00adered the two conditions\u2014amortization in three years and sustainability\u2014and rea\u00adsoned that he need\u00aded main\u00adte\u00adnance-free on-load tap-chang\u00aders, mean\u00ading those with vac\u00adu\u00adum tech\u00adnol\u00ado\u00adgy. The down\u00adside was that there were no such on-load tap-chang\u00aders in this pow\u00ader rat\u00ading class. \u201cSo we asked MR to devel\u00adop a VACUTAP for this pur\u00adpose.\u201d And MR was not ful\u00adly unpre\u00adpared to con\u00adfront this chal\u00adlenge since this type of VACUTAP had already been in pre\u00adlim\u00adi\u00adnary devel\u00adop\u00adment for years. But once it became much more of a real\u00adi\u00adty, MR start\u00aded focus\u00ading all its ener\u00adgy and work\u00ading at full force to get the new, mighty VACUTAP ready for oper\u00ada\u00adtion.<\/p>\n

Development no longer an winding road<\/h2>\n

The rat\u00aded-cur\u00adrent lim\u00adit for VACUTAP tech\u00adnol\u00ado\u00adgy was pre\u00advi\u00adous\u00adly at 1,300 amperes with\u00adout forced cur\u00adrent split\u00adting. MR engi\u00adneers worked to raise this lim\u00adit to a tremen\u00addous 3,200 amperes with\u00adin a very short time, sur\u00adpass\u00ading even the 3,000 ampere lim\u00adit cur\u00adrent\u00adly applic\u00ada\u00adble to high-main\u00adte\u00adnance oil tech\u00adnol\u00ado\u00adgy. The peo\u00adple at MR have devel\u00adoped a spe\u00adcial gadget\u2014the Advanced Flux Con\u00adtrol System\u2014to man\u00adage the high lev\u00adels of cur\u00adrent and the mag\u00adnet\u00adic fields in the on-load tap-chang\u00aders.<\/p>\n

The phase shifter will become a prof\u00aditable invest\u00adment over the first three years and will con\u00adtin\u00adue to oper\u00adate main\u00adte\u00adnance-free for anoth\u00ader 50 years.<\/p><\/blockquote>\n

Now, noth\u00ading stands in the way of the planned, giant phase-shifter trans\u00adformer. But how gigan\u00adtic does it need to be? Here, MR had a nice sur\u00adprise ready for Siemens and Ampri\u00adon: The new VACUTAP does not fea\u00adture any cur\u00adrent split\u00adting. The on-load tap-chang\u00ader can car\u00adry all the cur\u00adrent with\u00adin one sec\u00adtor, which has major con\u00adse\u00adquences for the trans\u00adformer design because the man\u00adu\u00adfac\u00adtur\u00ader does not need to install a com\u00adpli\u00adcat\u00aded wind\u00ading that takes up a lot of space on the coils, which them\u00adselves are the size of a VW bus. This allowed Siemens to think sim\u00adpler and small\u00ader. Due to this VACUTAP fea\u00adture alone, the phase\u00adshifter trans\u00adformer is sub\u00adstan\u00adtial\u00adly small\u00ader than the ver\u00adsions with cur\u00adrent split\u00adting. Small\u00ader means less mate\u00adr\u00adi\u00adal, lighter, and less insu\u00adlat\u00ading oil. Sim\u00adply put: more afford\u00adable.<\/p>\n

And it is eas\u00adi\u00ader to trans\u00adport. Ship\u00adping such a gigan\u00adtic device on land can only be done using trains, for which there are weight and size lim\u00adits that need to be observed for the trans\u00adport goods. How\u00adev\u00ader, this is not a prob\u00adlem for this slim giant.<\/p>\n

Money througRedispatching<\/h2>\n

One ques\u00adtion remains: How can such a high-tech hunk amor\u00adtize in no more than three years? The answer is sur\u00adpris\u00ading: through saved redis\u00adpatch\u00ading costs. In the Euro\u00adpean grid, espe\u00adcial\u00adly in Ger\u00admany, many redis\u00adpatch\u00ading mea\u00adsures can be traced back to con\u00adtrac\u00adtu\u00adal agree\u00adments that stip\u00adu\u00adlate who can con\u00adsume and sup\u00adply how much elec\u00adtric\u00adi\u00adty and when they can do so. These agree\u00adments are defined down to the minute, and every minute over or under the defined time lim\u00adits results in enor\u00admous con\u00adtrac\u00adtu\u00adal penal\u00adties. With phase shifters at the right interfaces\u2014usually on the bor\u00adders between coun\u00adtries or sup\u00adply areas\u2014Amprion can car\u00adry out all of these con\u00adtrac\u00adtu\u00adal mea\u00adsures eas\u00adi\u00adly and prompt\u00adly.<\/p>\n

\u201cWe expect sav\u00adings of one hun\u00addred mil\u00adlion euros over the next three years.\u201d<\/p>\n

Rein\u00adhard Bradt, Head of Grid Projects at Ampri\u00adon<\/cite><\/p><\/blockquote>\n

Rein\u00adhard Bradt says, \u201cUse sim\u00adu\u00adla\u00adtions at a suit\u00adable loca\u00adtion showed sav\u00adings of more than one hun\u00addred mil\u00adlion euros after deduc\u00adtion of the invest\u00adment costs aris\u00ading over the first three years of oper\u00ada\u00adtion.\u201d Com\u00admis\u00adsion\u00ading is sched\u00aduled for 2023. The phase shifter will become a prof\u00aditable invest\u00adment with\u00adin the first three years and will then con\u00adtin\u00adue to oper\u00adate main\u00adte\u00adnance-free for anoth\u00ader 40 to 50 years. Bradt adds, \u201cUsing this device will make sense for opti\u00admiz\u00ading the pow\u00ader flow near the bor\u00adders in the Ampri\u00adon grid even after the ongo\u00ading grid expan\u00adsion is com\u00adplet\u00aded.\u201d<\/p>\n
