Abstrakt
Maailma energiavajadus suureneb koos inimkonna suurenemisega aasta aastalt. Puhaste ja jätkusuutlike energiakandjate rakendamine on käesoleva ajastu üks suurimaid väljakutseid. Ühe võimalusena on kasutada energiatootjatena päikeseelektrijaamu.
Päikeseelektrijaama kui elektripaigaldist peab olema ohutu käidelda, mis eeldab vastamist kokkulepitud normidele. Elektriliste suuruste mõõtmine on viis kontrollimaks vastavust nõuetele ja seeläbi tagamaks inimeste ja seadmete ohutus. Varasemalt on alalisvoolu osa mõõtmised jäänud tagaplaanile kuid tehnoloogia laialdasema kasutuselevõtuga muutuvad need üha aktuaalsemaks.
Eesmärk oli tutvustada alalisvooluosa kontrollimiseks mõeldud mõõtevahendeid, viia läbi kontrollmõõtmised, tutvustada tulemusi ning nende põhjal analüüsida paigaldise toimimist. Mõõtmistel selgus, et paigaldis vastab projektile, on õigesti ehitatud ja mõõdetud osas funktsioneerib eelduslikus režiimis. Ühtegi probleemi ei tuvastatud. Käesolevat tööd võib kasutada tutvustamaks päikeseelektrijaama olemust ja tema ekspluateerimisega seotud nüansse.
The world’s energy demand increases year by year alongside the growth of humankind. The implementation of clean and sustainable energy carriers is one of the greatest challenges of our present time. One possible solution is the use of solar power plants as energy producers. The solar power plant as an electrical installation must be safe to operate, which requires compliance with established standards. Measuring electrical quantities is a way to verify this compliance and thereby ensure the safety of both people and equipment. In the near past, direct current side measurements have often been overlooked, but with the broader adoption of technology, they are becoming increasingly relevant. The aim was to introduce measuring instruments intended for inspecting the DC side, to carry out verification measurements, present the results, and analyze the functioning of the installation based on those results. The measurements revealed that the installation complies with the design, is correctly built, and functions in the expected mode in the measured section. No issues were identified. This work can be used to introduce the concept of a solar power plant and the nuances related to its operation.
