Töös esitatakse väikese Mohni saare autonoomse toiteallika mudel. See süsteem on välja töötatud päikese- ja tuuleenergia taastuvatel energiaallikatel koos varudiiselgeneraatoriga.
Käesoleva lõputöö eesmärgiks on lahendada Eesti saare elektrifitseerimise probleeme.
Hinnatakse majanduslikku efektiivsust ja tehakse soovitusi saare elektrifitseerimise parandamiseks. Uurimismetoodika põhineb kirjanduse ülevaatel, saare energiavajaduse uurimisel, energiatootmise analüüsil ja parima variandi valikul.
Simulatsiooni järeldus oli, et kõige optimaalsem on kasutada päikese- ja tuuleenergiat kasutavat kombineeritud süsteemi. Arvestades projekti maksumust, on sellise kombineeritud toitesüsteemi paigaldamine kohtadesse, kus on olemas ühendus tsentraalse elektrivõrguga, ebaotstarbekas.
Erandiks on elektrivõrgust kaugemal asuvad objektid. Selliste objektide hulka kuuluvad Eesti väikesaared.
The paper presents a model of autonomous electric power supply for the small island of Mohni. This system is developed on the basis of renewable energy sources of solar and wind, with a backup diesel generator. The purpose of this thesis is to solve the problems of electrification of the Estonian island. Economic efficiency is assessed and recommendations are made to improve the electrification of the island. The research methodology is based on the analysis of the literature, the study of energy demand on the island, the analysis of energy production and the selection of the best option. The conclusion of the simulation was that it is most optimal to use a combined system using solar and wind energy. Given the cost of the project, installing such a combined power supply system in places where a central electrical connection is available is not practical. The exception is objects remote from the electrical network. These objects include the small islands of Estonia.
