Abstract

Autonoomtoitega tänavavalgustite tööpõhimõtteks on valgustada teatud ala ilma, et valgusti oleks ühendatud elektrivõrguga. Sellist tüüpi valgustid leiavad kasutust aladel, milleni ei ole võimalik elektrivõrku viia. Autonoomtoitega tänavavalgustid on nii keskkonnaaspektist kui rahaliselt säästlikumad, nende paigaldamine ei sõltu elektrivõrkude olemasolust, vaid alternatiivsetest energiaallikatest –kas päikese- või tuuleenergiast. Enamasti on kasutusel päikesepaneelidega autonoomsed tänavavalgustid, millel on ka energiasalvesti ning mõningal juhul ka alternatiivse energiaallikana tuulegeneraator. Eestis on autonoomseid tänavavalgusteid kasutusel vähem, kui mujal maailmas, kuid asulavälistel teedel ja bussipeatustes on need kasutust leidnud. Lõputöös tehtud küsitluse tulemusel selgus, et vastanud valdade esindajatest on autonoomsete tänavavalgustitega kokku puutunud vaid 11,1% vastanutest, ning selgus, et valgusti võiks olla intensiivsem, kuigi hooldamine ning jooksvad kulutused on selle puhul minimaalsed. Lõputöös on toodud ülevaade näidisprojektist, mis sobiks Eesti kliimasse ning mida saaks kasutada autonoomtoitega tänavavalgustite rajamisel asulavälisele teele. Samuti on töös välja toodud tasuvusarvutused ning autonoomtoitega tänavavalgustite kasutegurid. Lõputöö annab ülevaate autonoomsete tänavavalgustitega seotud päikesepaneelidest ning nende tööpõhimõtetest, energiasalvestitest ning lühidalt ka autonoomtoitega tänavavalgustitel kasutatavatest LED-lampidest ning tänu ülevaatele valgustite tööpõhimõtetest on koostatud ka tasuvusarvutused ning näidisprojekt.

Abstract [en]

The following thesis “Autonomous Street Lighting Systems” is a brief description and analysis about autonomous street lights, an insight to their working basics. Autonomous street lighting is used to light an area without being connected to a power grid. This type of lighting systems are usually used in areas which are not compatible for power grids. Autonomous street lighting systems are enviromentally and financially economical, their mounting isn’t dependent on a power network, but they work using alternative power sources, such as solar or wind power. The most well known and used autonomous street light uses solar energy, has an electric drive and sometimes uses an alternative source of energy -usually wind power. Autonomous street lighting systems are not as well known and used as they are in other parts of the world. In Estonia, they are mostly used in bus stops and other smaller roads outside of towns and cities. The thesis also consists of a questionaire, which concluded that only 11,1% of Estonian counties have used or are using autonomous street lighting systems. It turned out that the 11,1% of counties who us autonomous street lighting systems, would prefer it to be much more intense, although the maintenence costs are minimal. This thesis gives an overview to a sample project about autonomous street lights outsite of a town/city and which would be a suitable solution for the Estonian climate. The thesis also includes the cost effectiveness calculations and other factors of efficiency for autonomous street lighting systems. The reader will also find a brief description of solar panels and their working principles in connection to autonomous street lights, and also a description of electric drives and LED-lamps. The thesis also includes a brief overview of cost effectiveness calculations for Estonian climate and a sample project for the autonomous street lighting systems in Estonia.
