Total Harmonic Solution\u2014it certainly sounds like a system that can solve any problem. What does it involve exactly?<\/h3>\n

That\u2019s pre\u00adcise\u00adly what we want to achieve with the Total Har\u00admon\u00adic Solu\u00adtion. It is a mod\u00adu\u00adlar sys\u00adtem com\u00adpris\u00ading pas\u00adsive and active fil\u00adter solu\u00adtions which can be used
\nto elim\u00adi\u00adnate all kinds of unwant\u00aded har\u00admon\u00adics in low-volt\u00adage and medi\u00adum-volt\u00adage net\u00adworks. Includ\u00ading those that are set to increase in the future.
\n<\/p>\n

Why was this development necessary? What can we expect to see in the future?<\/h3>\n

Net\u00adworks have changed. Back when the world was sim\u00adple, all we had to do to keep the volt\u00adage sta\u00adble was com\u00adpen\u00adsate for reac\u00adtive pow\u00ader. Things start\u00aded to change in the 2000s: More and more fre\u00adquen\u00adcy-con\u00adtrolled dri\u00adves are now used in machines. These are very ener\u00adgy-effi\u00adcient, but the pow\u00ader elec\u00adtron\u00adics have a neg\u00ada\u00adtive impact on the net\u00adwork which can crip\u00adple entire pro\u00adduc\u00adtion lines.<\/p>\n

\u201eSmall pow\u00ader elec\u00adtron\u00adics break quick\u00adly when sub\u00adject\u00aded to high\u00ader vibra\u00adtions, which can be expen\u00adsive when a whole hall is lit with LED lamps.\u201c<\/p><\/blockquote>\n

To begin with, it was main\u00adly the fifth har\u00admon\u00adic that caused problems\u2014which could ini\u00adtial\u00adly be rec\u00adti\u00adfied with pas\u00adsive fil\u00adters. But as the num\u00adber of fre\u00adquen\u00adcy-con\u00adtrolled dri\u00adves grew, addi\u00adtion\u00adal har\u00admon\u00adics emerged: We now had to deal with the sev\u00adenth, eleventh, right up to the 51st har\u00admon\u00adic. This is done with active fil\u00adters. And now we have a sit\u00adu\u00ada\u00adtion where supra\u00adhar\u00admon\u00adics \u2014 vibra\u00adtions in high\u00ader fre\u00adquen\u00adcy ranges of two to nine kilo\u00adhertz \u2014 are caus\u00ading prob\u00adlems.<\/p>\n

Clean volt\u00adage is cru\u00adcial to ensur\u00ading reli\u00adable oper\u00ada\u00adtion in numer\u00adous appli\u00adca\u00adtions. Unwant\u00aded grid feed\u00adback effects can dis\u00adrupt oper\u00ada\u00adtion, result\u00ading in addi\u00adtion\u00adal costs and even total fail\u00adure. With the Total Har\u00admon\u00adic Solu\u00adtion mod\u00adu\u00adlar sys\u00adtem, this kind of dis\u00adrup\u00adtion can be pre\u00advent\u00aded with\u00adout any need for com\u00adpli\u00adcat\u00aded plan\u00adning work. The four exam\u00adples below demon\u00adstrate how the Pow\u00ader Qual\u00adi\u00adty fil\u00adter solu\u00adtion can be used to ensure sta\u00adble volt\u00adage.<\/p>\n<\/div>\n<\/div>\n

The auto\u00admo\u00adtive indus\u00adtry is a clas\u00adsic field of appli\u00adca\u00adtion for fil\u00adter solu\u00adtions. In this sec\u00adtor, pow\u00ader elec\u00adtron\u00adics enable reli\u00adable, high\u00adly auto\u00admat\u00aded pro\u00adduc\u00adtion on a mas\u00adsive scale. This goes hand in hand with a con\u00adsid\u00ader\u00adable risk of dis\u00adrup\u00adtion\u2009\u2014\u2009but, for\u00adtu\u00adnate\u00adly, this risk can be eas\u00adi\u00adly min\u00adi\u00admized with the right fil\u00adter solu\u00adtions.<\/p>\n<\/div>\n<\/div>\n

The water indus\u00adtry is keen to max\u00adi\u00admize its ener\u00adgy effi\u00adcien\u00adcy. To this end, pow\u00ader gen\u00ader\u00ada\u00adtion plants (such as solar pow\u00ader plants) are increas\u00ading\u00adly being inte\u00adgrat\u00aded into mod\u00adern treat\u00adment facil\u00adi\u00adties, com\u00adplete with fre\u00adquen\u00adcy con\u00advert\u00aders, in order to oper\u00adate elec\u00adtri\u00adcal pumps\u2009\u2014\u2009which are them\u00adselves increas\u00ading\u00adly being equipped with fre\u00adquen\u00adcy con\u00advert\u00aders as well. Dis\u00adrup\u00adtive har\u00admon\u00adics are there\u00adfore inevitable.<\/p>\n<\/div>\n<\/div>\n

When elec\u00adtric\u00adi\u00adty is being gen\u00ader\u00adat\u00aded from wind pow\u00ader, har\u00admon\u00adic cur\u00adrents often occur, dis\u00adrupt\u00ading the pow\u00ader qual\u00adi\u00adty with\u00adin the grid. If plants fre\u00adquent\u00adly exceed the pre\u00adscribed lim\u00adit val\u00adues in this regard, they have to be removed from the grid. In the worst cas\u00ades, they may even lose their oper\u00adat\u00ading licence.<\/p>\n<\/div>\n<\/div>\n

<\/i><\/i>Example 4: Ships<\/a><\/h3>\n

\u00a9 Jens Umbach<\/figcaption><\/figure>\n

Ships are fit\u00adted with com\u00adplex elec\u00adtron\u00adics. Fre\u00adquen\u00adcy-con\u00adtrolled dri\u00adves for com\u00adpres\u00adsors, bow and stern thrusters, main dri\u00adves with sev\u00ader\u00adal megawatts of pow\u00ader, as well as pow\u00ader invert\u00aders for shore pow\u00ader sup\u00adply are just some of the tech\u00adni\u00adcal inno\u00adva\u00adtions being put to use in the ship\u00adping sec\u00adtor. As a result, the on-board pow\u00ader sup\u00adply can quick\u00adly become over\u00adloaded by har\u00admon\u00adics.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

This is due to the use of active front ends (AFEs)\u2014a type of fre\u00adquen\u00adcy converter\u2014which are set to become much more wide\u00adspread in the future. In the past, supra\u00adhar\u00admon\u00adics didn\u2019t cause any\u00adone any prob lems\u2014a punch\u00ading machine is robust enough to with\u00adstand them\u2014but mod\u00adern loads are becom\u00ading more and more sen\u00adsi\u00adtive, as shown by the exam\u00adple of LED lights. Small pow\u00ader elec\u00adtron\u00adics break quick\u00adly when sub\u00adject\u00aded to high\u00ader vibra\u00adtions, which can be expen\u00adsive when a whole hall is lit with LED lamps. We there\u00adfore real\u00adized that we need\u00aded to find a way to solve these prob\u00adlems once and for all.<\/p>\n

What was your solution?<\/h3>\n

The sys\u00adtem is very much based on tried-and-test\u00aded tech\u00adnol\u00ado\u00adgy. The GRIDCON\u00ae CHF pas\u00adsive fil\u00adter elim\u00adi\u00adnates the fifth har\u00admon\u00adic. For some appli\u00adca\u00adtions, this mod\u00adule will be enough. More exten\u00adsive pro\u00adtec\u00adtion is offered by the GRIDCON\u00ae ACF active fil\u00adter, which cov\u00aders the range up to the 51st har\u00admon\u00adic. And for supra\u00adhar\u00admon\u00adics, there is our new\u00adly devel\u00adoped SHU fil\u00adter mod\u00adule. Thanks to the mod\u00adu\u00adlar struc\u00adture, cus\u00adtomers can select pre\u00adcise\u00adly what they need, and retro\u00adfits are also pos\u00adsi\u00adble.<\/p>\n

\u201cThanks to the Total Har\u00admon\u00adic Solu\u00adtion, prob\u00adlems with har\u00admon\u00adics will be a thing of the past.\u201d<\/p><\/blockquote>\n

But what makes the Total Har\u00admon\u00adic Solu\u00adtion real\u00adly spe\u00adcial is the device soft\u00adware that we have spent years hon\u00ading and opti\u00admiz\u00ading. The soft\u00adware mea\u00adsures the har\u00admon\u00adics and the algo\u00adrithm con\u00adtin\u00adu\u00adous\u00adly ana\u00adlyzes the inter\u00adfer\u00adence lev\u00adel and auto\u00admat\u00adi\u00adcal\u00adly coun\u00adter\u00adacts it to ensure that the defined lim\u00adit val\u00adues are not exceed\u00aded. When it came to the pro\u00adgram\u00adming, we made sure that we incor\u00adpo\u00adrat\u00aded all of the expe\u00adri\u00adence our ser\u00advice tech\u00adni\u00adcians have had in the field. We can\u2019t sim\u00adply do things \u201cby the book\u201d if we want to reflect real\u00adi\u00adty.
\n.<\/p>\n

Filter solutions have a reputation for being very complicated \u2026<\/h3>\n

That\u2019s true. There are numer\u00adous indi\u00advid\u00adual solu\u00adtions in use in the field which are high\u00adly com\u00adplex and over\u00adsized. Para\u00adme\u00adter\u00adi\u00adza\u00adtion can also be extreme\u00adly labo\u00adri\u00adous dur\u00ading com\u00admis\u00adsion\u00ading or in the event of net\u00adwork mod\u00adi\u00adfi\u00adca\u00adtions. With our stan\u00addard\u00adized approach, it\u2019s a dif\u00adfer\u00adent sto\u00adry. We want\u00aded a solu\u00adtion that\u2014to put it bluntly\u2014was as sim\u00adple, reli\u00adable, and durable as a light\u00adning arrester and which could be installed based on the plug-and-play prin\u00adci\u00adple, wher\u00adev\u00ader it is need\u00aded or wher\u00adev\u00ader there is enough space.<\/p>\n

Depend\u00ading on the sit\u00adu\u00ada\u00adtion, some\u00adtimes all that is required is a com\u00adpact wall device. With our mod\u00adu\u00adlar sys\u00adtem, that can be eas\u00adi\u00adly arranged. Cur\u00adrent trans\u00adform\u00aders are not required and par\u00adal\u00adlel oper\u00ada\u00adtion with oth\u00ader fil\u00adters is also possible\u2014it doesn\u2019t get more flex\u00adi\u00adble than that. The sys\u00adtem reg\u00adu\u00adlates itself auto\u00admat\u00adi\u00adcal\u00adly and fil\u00adters exact\u00adly what needs to be fil\u00adtered. And if a com\u00adpa\u00adny mod\u00adi\u00adfies its pro\u00adduc\u00adtion line and the net\u00adwork changes as a result, that\u2019s no prob\u00adlem either\u2014the new para\u00adme\u00adter\u00adi\u00adza\u00adtion takes care of itself with no need for a vis\u00adit from a ser\u00advice tech\u00adni\u00adcian.<\/p>\n

What applications is the solution suitable for?<\/h3>\n

It is aimed at any\u00adone who has prob\u00adlems with har\u00admon\u00adics. This applies to vir\u00adtu\u00adal\u00adly all high\u00adly auto\u00admat\u00aded pro\u00adduc\u00adtion facil\u00adi\u00adties, such as those in the auto\u00admo\u00adtive indus\u00adtry. But our fil\u00adter solu\u00adtions are also in demand at sewage works, at wind and solar farms, and even for on-board pow\u00ader sup\u00adplies on ships.<\/p>\n
