Abstrakt
Käesolevas töös on käsitletud kõrgepinge õhuliinide projekteerimist SES tarkvaraga. Töö
eesmärgiks on tutvustada potentsiaaliühtlustuse projekteerimise protsessi SES tarkvaraga.
Peamiseks fookuseks on suure lühise korral maa potentsiaali tõusu haldamine ja ohtlike
puutepingete ohututele tasemetele toomine. Käesoleva töö raames on lähtutud
võrguettevõtja nõuetest, vastavatest standarditest ja üldistest tehnilistest normidest. Töös
on süvitsi käsitletud 330 kV vantkandemasti potentsiaaliühtlustuse projekteerimist alates
algsest materjalide kogumisest, masti baasi modelleerimisest, liini lühisvoolude
modelleerimisest, lõpliku sobiliku potentsiaaliühtlustuse lahendusest kuni tervikliku
puutepinge kontrollini. Lisaks on analüüsitud koostatud lahendust, vaadates potentsiaalide
3D diagrammi. Töö lisaväärtus seisneb selles, et antud teema puhul ei esine liialt eesti
keelseid materjale.
Töö edasiarendusena peaks uurima programmiga suureloomuliste maanduspaigaldiste
projekteerimist, kasutades SESi poolt pakutavat CDEGS paketti ja sellega kaasnevaid
mooduelid.
This thesis describes the process of designing overhead power lines potential grading systems. The aim of this study is to present the design process and methods of designing overhead power lines potential grading systems using SES software. The main focus of this thesis is managing the ground potential rise at fault location and keeping touch voltages under the necessary safety limits. In this study, the design process is based on the requirements of the power distribution company, relevant standards and regular construction norms. In this thesis, the author thoroughly explored the design of potential grading systems for a 330 kV guywire suspension tower. The process began with basic information gathering, modeling of the tower, and concluded with the implementation of an appropriate solution whilst doing the mandatory touch potential check. The author also analyzed the potential grading system by using the 3D diagram. The added value of this thesis is the fact that there are not many articles of this topic in Estonian. For future work, the use of SES software should be explored in designing large scale grounding solutions with the application of the CDEGS software package.
