Uninterruptible power supply systems for Hydroelectric power plant Đale The company KONČAR – ELECTRONICS AND INFORMATICS Ltd. for production and services (INEM) has successfully produced and completed the final factory testing of uninterruptible power supply systems for Hydroelectric power plant Đale as part of the project contracted with HEP Proizvodnja by KONČAR – Power Plant and Electric Traction Engineering Ltd.. There are six uninterruptible power systems, one of which is a double redundant system ± 220 VDC each with three modular thyristor rectifiers of the type LH 220V, 50 A and its own central microprocessor control unit. One system of ± 48 VDC will be connected to a system ± 220 VDC via a DC / DC converter, and one double redundant system -48 VDC each with three modular VF rectifiers of type BFS 48 V, 50 A, as well as three AC uninterruptible power systems for supply of all ICT equipment for process and business activities. Due to replacing the uninterruptible power supply system, the functionality, safety and availability of new control, signalling, protection, measurement, regulation, emergency lighting, IT and telecommunications equipment will be improved, whereby their replacement was foreseen upon completion of the reconstruction of all power supply systems.

Sustavi besprekidnih napajanja za Hidroelektranu Đale Društvo KONČAR – Elektronika i informatika d.o.o. (INEM) proizvelo je i uspješno provelo završna tvornička ispitivanja sustava besprekidnih napajanja za Hidroelektranu (HE) Đale u sklopu projekta koji je ugovorio KONČAR – Inženjering za energetiku i transport s HEP Proizvodnjom. Riječ je o šest sustava besprekidnih napajanja, od kojih je jedan dvostruki redundantni sustav ±220 VDC svaki s tri modularna tiristorska ispravljača tipa LH 220V, 50 A i vlastitom centralnom mikroprocesorskom upravljačkom jedinicom. Jedan sustav ±48 VDC bit će povezan sa sustavom ±220 VDC preko DC/DC pretvarača, a jedan sustav -48 VDC svaki s tri modularna VF ispravljača tipa BFS 48 V, 50 A, kao i tri sustava besprekidnog izmjeničnog napajanja za napajanje POSIS-a, ICT-a i PROCIS-a. Zamjenom sustava besprekidnih napajanja poboljšat će se funkcionalnost, sigurnost i raspoloživost novih uređaja za upravljanje, signalizaciju, zaštitu, mjerenje, regulaciju, nužnu rasvjetu, informatičku i telekomunikacijsku opremu čija zamjena je predviđena po završetku rekonstrukcije svih sustava napajanja.
