Abstract

Lõputöö käigus projekteeriti alajaama omatarbe keskuse lahendus vastavalt kliendi nõuetele ja projekti põhjal ehitati reaalne alajaama vahelduvomatarbe keskus. Lõputöö esimeses osas kirjeldati suures osas miks antud alajaam ehitati, selgitati kuidas sai alguse taastuv- ja tuuleenergia laiendatud kasutuselevõtt Rootsis. Millist rolli omab alajaam tuuleenergia tootmis projektis. Selgitati, mis on omatarbe keskus ja mis on selle roll. Teises osas selgitati kliendi antud nõudeid tööle ja milline peab olema omatarbe keskuse funktsionaalsus ning ülesehitus valminud omatarbe keskusel. Kolmandas osas on välja toodud kuidas nägi välja lõputöö projekti tegemine, mis olid selles erinevad etapid ja mida tehti igas etapis. Põhjendati lühidalt, miks kasutati projekteerimisel just selliseid programme ning tehti lühike ülevaade nende omadustest. Viimases peatükis kirjeldatakse projektis tehtud lahendusi ning mille põhjal neid otsuseid tehti. Selgitati, kuidas leiti koormused, lühisvoolud, pingelangud ning mis rolli need omavad keskuse seadmete valikul. Toodi välja, mis nimiandmetega, kaitsesätetega seadmed valiti ja kuidas saavutati selektiivsus. Kirjeldati automaatikakappi ja selgitati reservlülitusautomaatika funktsiooni. Lõpptulemusena saab öelda, et lõputöö raames tehtud projekt sai teostatud edukalt ning lõputööeesmärgid said täidetud.

Abstract [en]

In the course of the thesis a solution was designed of the substations alternating current protection and control centre, according to the customer’s requirements. And on the basis of the project a working centre was built. The first part of the thesis largely describes why the substation was built and explains why and how use of renewable and wind energy has expanded in Sweden. What role does the substation have in the wind energy production project. The use of protection and control centre was explained. In the second part client requirements for the project are introduced and what the functionality and structure of the centre should look like. The third chapter describes the different stages of the project and what was done in each stage. An overview and explanation were given on the used programs involved and of their features. Last part of the thesis focuses on explaining the choices made in the project and reasons behind them. How loads, short-circuit currents, voltage drops were calculated and what role they have in device selection and dimensioning of the centre. It was pointed out what devices were chosen and what their features, nominal protection settings were and how selectivity was achieved. Also, the automation and control centre was introduced and explained. In the end it can be said that the project was successfully made within the framework of the thesis. And the different goals of the thesis were met and fulfilled.
