While this makes the machines sig\u00adnif\u00adi\u00adcant\u00adly more effi\u00adcient, they switch off if the volt\u00adage leaves the defined range. Where most deposits are found, such as in South Amer\u00adi\u00adca or Africa, the grids are gen\u00ader\u00adal\u00adly very unstable\u2014meaning that volt\u00adage fluc\u00adtu\u00ada\u00adtions occur more often there. But that\u2019s just the half of it. The mach\u00adines them\u00adselves also have reper\u00adcus\u00adsions on the grid.<\/p>\n
You mean the reactive power?<\/h3>\n
es, that too, reac\u00adtive pow\u00ader flows over\u00adload the lines. In this way, this prob\u00adlem is not new. But with mod\u00adern machines and their fre\u00adquen\u00adcy-con\u00adtrolled dri\u00adves, har\u00admon\u00adics also arise that have a neg\u00ada\u00adtive effect on the pow\u00ader qual\u00adi\u00adty. These grid impu\u00adri\u00adties can also inter\u00adfere with oth\u00ader con\u00adsumers.<\/p>\n

There\u00adfore, grid oper\u00ada\u00adtors set lim\u00adit val\u00adues, which mines and oth\u00ader large con\u00adsumers have to com\u00adply with. If the lim\u00adit val\u00adues are exceed\u00aded, this can become real\u00adly expen\u00adsive. It can result in fines or even dis\u00adcon\u00adnec\u00adtion. But the mine oper\u00ada\u00adtors also have an inter\u00adest in elim\u00adi\u00adnat\u00ading har\u00admon\u00adics, for a dif\u00adfer\u00adent rea\u00adson: they can inter\u00adfere with their own tech\u00adnol\u00ado\u00adgy. If sen\u00adsors or mea\u00adsure\u00adment tech\u00adnol\u00ado\u00adgy fail, pro\u00adduc\u00adtion stops.<\/p>\n
Which solutions does Reinhausen Power Quality offer to overcome this undesirable grid feedback?<\/h3>\n
In a nut\u00adshell: com\u00adpen\u00adsa\u00adtion sys\u00adtems for reac\u00adtive pow\u00ader and fil\u00adter cir\u00adcuit sys\u00adtems for har\u00admon\u00adics. But there isn\u2019t just a sin\u00adgle solu\u00adtion. Every mine is dif\u00adfer\u00adent, both with regard to the machine fleet and the topo\u00adgraphical fac\u00adtors. There is there\u00adfore usu\u00adal\u00adly only one of each of our sys\u00adtems in the world. But our GRIDCON\u00ae<\/sup> series gives us a trust\u00aded mod\u00adu\u00adlar sys\u00adtem which we can tap into.<\/p>\n \u201cThanks to the GRIDCON\u00ae<\/sup> range, mine oper\u00ada\u00adtors can improve their pow\u00ader qual\u00adi\u00adty and also uti\u00adlize the avail\u00adable infra\u00adstruc\u00adture more flex\u00adi\u00adbly.\u201d<\/p><\/blockquote>\n In gen\u00ader\u00adal, there is a clear trend toward dynam\u00adic com\u00adpen\u00adsa\u00adtion sys\u00adtems that can opti\u00admize load flows with pow\u00ader elec\u00adtron\u00adics almost in real time. This helps mine oper\u00ada\u00adtors avoid trans\u00admis\u00adsion loss\u00ades due to exces\u00adsive reac\u00adtive pow\u00ader and can thus also low\u00ader their ener\u00adgy costs. It is also pos\u00adsi\u00adble to get more out of trans\u00adform\u00aders and even con\u00adnect addi\u00adtion\u00adal dri\u00adves since reac\u00adtive pow\u00ader is off\u00adset on the process rail and does not go through the trans\u00adformer. Mine oper\u00ada\u00adtors can thus improve their pow\u00ader qual\u00adi\u00adty and also uti\u00adlize the avail\u00adable infra\u00adstruc\u00adture more flex\u00adi\u00adbly.<\/p>\n There is a spec\u00adi\u00adfied volt\u00adage range in which the grid oper\u00ada\u00adtor can allow the volt\u00adage to fluc\u00adtu\u00adate. If this range is vio\u00adlat\u00aded, our sys\u00adtems are also able to bring the volt\u00adage back to this range almost in real time. In turn, this then ensures sta\u00adble pro\u00adduc\u00adtion.<\/p>\n We get this ques\u00adtion fre\u00adquent\u00adly. 15 to 20 years. This always depends on the indi\u00advid\u00adual demand and how well the sys\u00adtems are main\u00adtained.<\/p>\n Yes. The appli\u00adca\u00adtion is not lim\u00adit\u00aded cop\u00adper mines; the sys\u00adtems can be used for min\u00ading as a whole as well as in oth\u00ader indus\u00adtries in which pow\u00ader\u00adful con\u00adsumers are con\u00adnect\u00aded to the grid.

The experts are involved from the con\u00adsul\u00adta\u00adtion phase, through the design stage, and even up to sys\u00adtem set\u00adup. The train\u00ading of employ\u00adees can also be tak\u00aden on if desired.<\/p>\n Solu\u00adtions from the GRIDCON\u00ae series are avail\u00adable for the design of the fil\u00adter cir\u00adcuit and com\u00adpen\u00adsa\u00adtion sys\u00adtems. GRIDCON\u00ae SVC, for exam\u00adple, is a sys\u00adtem that reduces har\u00admon\u00adics and improves the pow\u00ader fac\u00adtor.
