Power supply systems for Croatian TSO, TS 110/20 kV Medulin KONČAR – Electronics and Informatics has contracted to produce DC power supply systems at 220 and 48 V within the construction of 110 kV facility of Croatian TSO in TS 110/20 kV Medulin. All factory testing were successfully carried out in the presence of buyer and investor representatives at the beginning of July. Delivery and installation of the equipment is planned by the end of the month, and commissioning in September. 110/20 kV transformation station Medulin is a new power facility built for the growing needs for power supply of the constantly expanding tourist-oriented consumption Medulin Riviera and is one of the largest investments of HEP and Croatian TSO in Istria County lately. The construction of the joint facility is taking place in close coordination between HEP ODS and Croatian TSO. The 220 V DC power supply system will provide high-quality, uninterruptible power supply for the following important devices and equipment of the 110 kV facility: - motor drives and control circuits of 110 kV circuit breakers, disconnectors and earthing switches - position and alarm signalling in the 110 kV facility - power supply of control units of 110 kV fields - supply of relay protection for 110 kV facility - supply of remote control equipment, billing measurement and quality control of electricity - power supply of emergency lighting - the power supply of the inverter for uninterrupted power supply of a part of telecommunications equipment The 48 V supply system will provide the uninterrupted power supply of telecommunication equipment and protection signal transfer devices in the cabinet of secondary equipment of 110 kV feeder fields. Both power supply systems are the KONIS-B type with modular redundant rectifiers, maintenance-free battery and selective DC power distribution. The system is controlled by the KONLOG type microprocessor control unit. It manages the system in real-time and allows parameterization, local and remote insight into measurements and signalling. Communication is possible with a remote specialist service centre, which significantly contributes to reducing maintenance costs and increases the reliability and availability of the power system.

Sustavi napajanja za HOPS, TS 110/20 kV Medulin U okviru izgradnje 110 kV postrojenja HOPS-a u TS 110/20 kV Medulin Končar – Elektronika i informatika ugovorila je proizvodnju sustava napajanja istosmjernim naponima 220 i 48 V. Početkom mjeseca srpnja uspješno su provedena sva predviđena tvornička ispitivanja u prisutnosti predstavnika Kupca i Investitora. Isporuka i ugradnja opreme predviđena je do kraja mjeseca, a puštanje u rad tijekom rujna. Transformatorska stanica 110/20 kV Medulin je novi elektroenergetski objekt izgrađen zbog potrebe opskrbe stalno rastućeg konzuma turistički orijentirane medulinske rivijere i jedna je od najvećih investicija HEP-a i HOPS-a na području Istarske županije u posljednje vrijeme. Izgradnja zajedničkog objekta odvija se u tijesnoj koordinaciji između HEP ODS i HOPS. Sustav napajanja istosmjernim naponom 220 V omogućit će kvalitetno besprekidno napajanje sljedećih važnih uređaja i opreme 110 kV postrojenja: - motorni pogoni i krugovi upravljanja 110 kV prekidača, rastavljača i zemljospojnika - položajna i alarmna signalizacija u 110 kV postrojenju - napajanje upravljačkih jedinica 110 kV polja - napajanje relejne zaštite 110 kV postrojenja - napajanje opreme daljijnskog vođenja, obračunskih mjerenja i kontrole kakvoće električne energije - napajanje nužne rasvjete - napajanje izmjenjivača za besprekidno napajanje dijela opreme telekomunikacija Besprekidno napajanje telekomunikacijske opreme i uređaja za prijenos signala zaštite u ormarima sekundarne opreme 110 kV vodnih polja omogućit će sustav napajanja 48 V. Oba sustava napajanja su tipa KONIS-B s modularnim redundantnim ispravljačima, akumulatorskom baterijom bez održavanja i selektivnim istosmjernim razvodom. Radom sustava upravlja mikroprocesorska upravljačka jedinica tipa KONLOG. Ona upravlja sustavom u realnom vremenu te omogućuje parametriranje, lokalni i daljinski uvid u mjerenja i signalizaciju. Moguća je komunikacija s daljinskim specijalističkim servisnim centrom, što bitno doprinosi smanjenju troškova održavanja i dodatnom povećanju pouzdanosti i raspoloživosti sustava napajanja.
