Uninterruptible power supply systems for Hydroelectric power plant Đale

The company KONČAR – Electronics and Informatics Inc. (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 Inc..

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.
