A<\/span>ll around the world, grid oper\u00ada\u00adtors are being con\u00adfront\u00aded with the same chal\u00adlenge: the fact that their equip\u00adment is reach\u00ading old age. It is no longer uncom\u00admon to see pow\u00ader trans\u00adform\u00aders with a ser\u00advice life of 50 years or more. One of the ques\u00adtions that every grid oper\u00ada\u00adtor is
\nfaced with is there\u00adfore \u2018What sort of shape is my fleet in?\u2019 Find\u00ading an answer to this ques\u00adtion is becom\u00ading more and more urgent: Fluc\u00adtu\u00adat\u00ading and high\u00ader loads result\u00ading from renew\u00adable ener\u00adgy sources are increas\u00ading\u00adly caus\u00ading the cru\u00adcial pieces of equip\u00adment need\u00aded to ensure a sta\u00adble pow\u00ader sup\u00adply to reach their lim\u00adits.<\/p>\n

To com\u00adbat this, Maschi\u00adnen\u00adfab\u00adrik Rein\u00adhausen has devel\u00adoped a con\u00addi\u00adtion-based method to iden\u00adti\u00adfy crit\u00adi\u00adcal units at an ear\u00adly stage: FLEETSCAN 2D. The two dimen\u00adsion\u00adal assess\u00adment matrix incor\u00adpo\u00adrates, first\u00adly, the like\u00adli\u00adhood of func\u00adtions fail\u00ading in order to mod\u00adel the reli\u00ada\u00adbil\u00adi\u00adty of the fleet. The sec\u00adond
\ndimen\u00adsion then con\u00adsid\u00aders the loss-of-life and is impor\u00adtant for mak\u00ading long-term invest\u00adment deci\u00adsions. The man\u00adu\u00adfac\u00adtur\u00ader-inde\u00adpen\u00addent eval\u00adu\u00ada\u00adtion tool is a lean solu\u00adtion on which oper\u00ada\u00adtors can rely to keep their fleets in shape.

1. Collect Data<\/h3>\n

A suf\u00adfi\u00adcient data\u00adbase is essen\u00adtial to car\u00adry out the con\u00addi\u00adtion assess\u00adment. To keep dis\u00adrup\u00adtion times and assess\u00adment work to a min\u00adi\u00admum, FLEETSCAN 2D offers three assess\u00adment stages. Depend\u00ading on how detailed the assess\u00adment needs to be, not all three stages have to be car\u00adried out. Trans\u00adformer data is already avail\u00adable in many cas\u00ades, so the work involved in record\u00ading the data is min\u00adi\u00admal.
\n<\/p>\n

<\/h5>\n
1st stage: existing data<\/h5>\n

The oper\u00ada\u00adtor pro\u00advides the data which is already avail\u00adable. This includes, for exam\u00adple, the mas\u00adter data of the trans\u00adform\u00aders, mea\u00adsure\u00adments that have already been car\u00adried out, and main\u00adte\u00adnance his\u00adto\u00adry infor\u00adma\u00adtion.<\/p>\n

2nd stage: on-site appraisal<\/h5>\n

The sec\u00adond stage involves an on-site appraisal which is car\u00adried out dur\u00ading oper\u00ada\u00adtion. In a visu\u00adal inspec\u00adtion, an MR expert uses a check\u00adlist to exam\u00adine the trans\u00adformer for signs of cor\u00adro\u00adsion, leaks, and vis\u00adi\u00adble dam\u00adage to the bush\u00adings and fans. The expert then car\u00adries out infrared ther\u00admog\u00adra\u00adphy and a com\u00adplete oil analy\u00adsis.<\/p>\n

3rd stage: complete testing<\/h5>\n

If, after the first two stages, there are any indi\u00adca\u00adtions of more sig\u00adnif\u00adi\u00adcant dam\u00adage, MR per\u00adforms tar\u00adget\u00aded test\u00ading involv\u00ading exten\u00adsive mea\u00adsure\u00adments. These include dynam\u00adic resis\u00adtance and par\u00adtial dis\u00adcharge mea\u00adsure\u00adments which require the trans\u00adformer to be tak\u00aden off the grid.<\/p>\n<\/div>\n<\/div>\n

2. Everything at a Glance<\/h3>\n

FLEETSCAN 2D makes it pos\u00adsi\u00adble to clear\u00adly save all col\u00adlect\u00aded data using brows\u00ader-based soft\u00adware. This enables grid oper\u00ada\u00adtors to retrieve
\nall rel\u00ade\u00advant infor\u00adma\u00adtion for any trans\u00adformer in the fleet at any time.<\/p>\n

3. Evaluation<\/h3>\n

Fol\u00adlow\u00ading data record\u00ading, it is time to move on to the core ele\u00adment of FLEETSCAN 2D: the eval\u00adu\u00ada\u00adtion. Using an algo\u00adrithm devel\u00adoped by MR and the Uni\u00adver\u00adsi\u00adty of Wup\u00adper\u00adtal, the con\u00addi\u00adtion analy\u00adsis is car\u00adried out in two indices:<\/p>\n
