Käesolevas töös on kirjeldatud 110 kV õhuliini projekteerimist programmiga PLSCADD. Käsitletud on projekteerimisprotsess alates algandmete kogumisest,
koormusjuhtumite koostamisest kuni lõpliku kontrollitud õhuliinini. Töö eesmärgiks on
tutvustada projekteerimisprotsessi PLS-CADD programmiga õhuliini projekteerimisel.
Töös kasutatakse asjakohaseid standardeid ja seaduseid ning võrguettevõtja tehnilisi
nõudeid. Töö tulemusena valiti 110 kV õhuliinile uus trass pikkusega ~15 km mis vastab
tellija poolt esitatud nõuetele, arvestab kohaliku omavalitsuse ja teiste ametkondade poolt
väljastatud projekteerimistingimustega. Kokku määrati antud töö raames viiekümenele
mastile asukoht, tüüp ja kõrgus, kontrolliti õhkvahemike vastavust ning koostati õhuliini
pikiprofiil. Projekteeritud õhuliin on kontrollitud PLS-CADD programmiga, et liini
elemendid peaksid mehaaniliselt vastu neile mõjuvatele koormustele. Täiendavalt on
antud töö raames määratud vabaltseisva metallsõrestik kandemasti ülemise otsa
geomeetria, asendamaks traditsiooniliselt kasutatavat hetkel kättesaamatut
raudbetoonkandemasti.
Töö edasiarendusena peaks uurida antud programmi kasutamist jaotusvõrkude
projekteerimisel, selle jaoks tuleks koostada vajalikud koormusjuhtumite failid, mastide
ja juhtmete mudelid.
This thesis describes the design process of a 110 kV overhead line using the PLS-CADD software. It encompasses the entire design process, from initial data collection and load case development to the finalised, checked the overhead line. The aim of this study is to provide an overview of the design process using the PLS-CADD software in the context of the overhead line design. Relevant standards, laws, and technical requirements from network operators are applied throughout. As a result of this study, a new 15 km route for the 110 kV overhead line was chosen, which adheres to the requirements provided by the client, and takes into account the design conditions issued by local governments and other authorities. In the context of this study, the location, type, and height of fifty towers were determined, clearances were verified, and a longitudinal profile of the overhead line was created. The designed overhead line was checked using the PLS-CADD software to ensure all line elements could mechanically withstand the loads they are exposed to. Additionally, within the scope of this work, the top-end geometry free-standing steel lattice support tower was determined to replace the currently inaccessible reinforced concrete support tower traditionally used. For future developments, the use of this software for the design of distribution networks should be explored. This would require the creation of necessary load case files, tower and conductor models.
