The pilot project titled “Remote meter and sensor reading – SenzoriKA”
On July 15th, Damir Mandić, Mayor of Karlovac, Mate Botica, Member of the Managing Board and Director of Transmitters and Communications Ltd. (OiV), and Zvonimir Jurin, Member of the Managing Board of KONČAR – Electronics and Informatics, have officially signed an Agreement on the implementation of the pilot project titled “Remote meter and sensor reading – SenzoriKA”.
The project will include the implementation of a “smart city” test system with data visualization for the citizens, which will allow the collection of data on the consumption of all energy sources and water, as well as information about air quality and temperature, collected waste and parking space availability.
The system is based on an integrated solution designed by OiV and KONČAR – Electronics and Informatics, which uses the OIV Smartino IoT (Lora WAN) technology for the transfer of data, and KONČAR’s MARS software for data processing and visualization.
The system enables the acquisition of data from devices produced by different manufacturers, as well as the monitoring and control via the LoRaWAN low-power radio network, which allows the use of battery-powered devices, and all data are available to the business systems of the city companies, and, if necessary, to the citizens.
Said technology covers a wide range of applications, including water meters, gas meters, electricity meters, management and control of public lighting, air quality sensors, parking lot occupancy, sensors for monitoring water levels, temperature, humidity, and water quality sensors, and GPS tracking. In addition, it allows the integration of other technologies and the existing terminals into the LoRaWAN ecosystem.
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.
Reconstruction of the DC power supply system in TS Rakitje
In March 2019 the Company KONČAR – Electronics and Informatics successfully completed the final factory testing of the DC voltage supply system for the 110/20 kV transformer station Rakitje, Bestovje. The client was the Croatian Transmission System Operator (HOPS), the Transmission Area of Zagreb.
The business activities included manufacturing, factory testing and delivery of three dual-power 220 VDC systems, one dual-system – 48 VDC and three AC distribution cabinets.
The 220 VDC power supply is a conventional type for transmission transformer stations KONIS-B, 220V, 40A, used for supplying the electromotor drives of high voltage and medium voltage switches, control, protection, signalization and emergency lighting. The 48 VDC type, KONIS-B, 48V, 200 A is planned for supplying telecommunication devices and local and remote signalization.
At the end of March, the factory acceptance test and the equipment delivery were performed. The assembly and commissioning of the equipment will be realized during the planned reconstruction of the 110 kV facility in TS Rakitje.
