PLAN-tekniikalla toteutetun etäluentajärjestelmän häiriöt

Abstract

Tämän opinnäytetyön tarkoituksena oli selvittää ja tutkia Kuopion Energia Liikelaitoksen PLAN-tekniikalla toteutettua etäluentajärjestelmää häiritseviä tekijöitä. Lisäksi työssä oli tarkoitus selvittää, kuinka esiintyviä häiriöitä voidaan kompensoida ja kuinka etäluennan toimintavarmuutta voidaan parantaa. PLAN-tekniikka perustuu sähköverkossa tapahtuvaan tiedonsiirtoon ja verkossa liikkuvan datan modulointiin, eli PLC-tekniikkaan. PLAN-tekniikka on suhteellisen uusi ja tuntematon tekniikka, joten häiritsevien tekijöiden selvitys on tärkeää. Tutkimustyö aloitettiin selvittämällä sähköverkossa esiintyviä PLAN-tekniikkaa häiritseviä, sekä PLAN-signaalia vaimentavia tekijöitä Kuopiossa kesän 2013 aikana. Työhön kuului myös löydettyjen häiriöiden kompensoiminen, sekä vaimennustapauksissa PLAN-signaalin tasojen parantaminen. Sähköverkossa suoritettiin kesän aikana paljon mittauksia ja häiriö- ja vaimennustapaukset kirjattiin ylös. Opinnäytetyön tuloksena saatiin kattavasti tietoa erilaisista PLAN-tekniikkaa häiritsevista tekijöistä ja häiriöiden kompensoinnista. Lisäksi saatiin kattavasti tietoa PLAN-tekniikalle haasteellisita verkkoympäristöistä signaalia vai-mentavien tekijöiden osalta. Lisäksi työn kirjallinen osuus toimii jatkossa oppaana PLAN-tekniikkaa häiritsevien ja vaimentavien tekijöiden ja niiden kompensoinnin osalta.

The purpose of this thesis was to research what things are disturbing PLAN technology based electrical remote reading of Kuopion Energia Commercial Enterprice as well as to research how to compensate discovered interferences and how to improve the reliability of electrical remote reading. PLAN technology is based on PLC technology. In other words, PLC technology means data transmission in electric network and modulation of transmitted data. PLAN technology is quite new and unknown, so researching disturbing things is important. The thesis began by researching what kind of things are disturbing PLAN technology and what kind of things were weakening PLAN signals in Kuopio during the summer of 2013. The thesis also included compensating the discovered interferences and improving PLAN signal quality. A lot of measurements were carried out in the electric network during the summer and all interferences and signal weakening cases were written down. The outcome of this thesis was a lot of information about different kinds of things that disturb PLAN technology and solutions how to compensate the discovered interferences. The thesis also produced a lot of information about what kind of networks are challenging for PLAN technology. This thesis report can also be a guidebook for PLAN technology interferences in the future.
