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.

INEM TS Rakitje

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.

First KONČAR Voltage Regulators in the UK

Konreg S1000 type voltage regulators have been utilised for the first time in the UK on the Lynemouth Power Station biomass conversion project (North East England). The station consists of three 155MVA units, all of which are now running with S1000 based excitation systems.

The KONregS1000 based excitation system is single channel for the pilot exciter and dual channel for the main exciter, a total of three regulators per unit. KONČAR – Electronics and Informatics Inc. (INEM) delivered the KONreg S1000 regulators along with engineering and software support; Excitation & Engineering Services (EES) designed and manufactured the overall system.

Commissioning of the first unit commenced in January 2018 and was performed by both KONČAR and EES.

KONČAR and EES worked together to implement new functionality to the S1000 such as the manual restrictive limiter, in order to meet the UK National Grid code requirements.

Grants for the project “KONTRAC GP170DC_SK – Development of the tramway propulsion converter with supercapacitor module”

KONČAR – Electronics and Informatics Inc. has applied for an open call from the Ministry of Economy, Entrepreneurship and Crafts of the Republic of Croatia for the awarding of grants for the project “KONTRAC GP170DC_SK – Development of the tramway propulsion converter with supercapacitor module”. The project was approved, and the Grant Agreement was signed on 2nd November 2018 at the Ministry of Economy, Entrepreneurship and Crafts of the Republic of Croatia.

This is a research and development project and it will be financed from the European Regional Development Fund, that is intended for increasing the development of new products and services that result from research and development activities. Partner of the project applicant, KONČAR – Electronics and Informatics Inc., is University of Zagreb, Faculty of Electrical Engineering and Computing. The project is to be realized within 36 months. Industrial research will last for the first two years of the project, and the experimental development will take place in the third project year.

The total eligible costs of the project amount to HRK 10,558,168.91, and the grant is HRK 6,528,270.54.

By the project “KONTRAC GP170DC_SK – Development of the tramway propulsion converter with supercapacitor module ” the project applicant, KONČAR – Electronics and Informatics Inc., and its project partner, University of Zagreb, Faculty of Electrical Engineering and Computing, are launching industrial research and experimental development in the field of advanced transport systems. The aim of the project is mastering the development and innovation of high value-added equipment by which the energy efficiency of existing solutions in the field of transport systems is being increased. The obtained results will be used for later commercial application thanks to the main realized project aims: developed tramway propulsion converter with a braking energy storage unit for the vehicle and its subsequent use, developed energy storage unit with built-in system for uniform voltage cell distribution, developed and implemented algorithms of controlling charging and discharging cycles of energy storage units that will increase energy efficiency and ensure the maximum lifetime of the energy storage units and technical documentation for the serial production of the tramway propulsion converter and energy storage units. The project envisages registration of a trademark, industrial design and a patent.

During development of the tramway propulsion converter with the energy storage units, the existing knowledge and skills acquired in the production of converters will be applied, especially in the production of converters for rail vehicles, and the project activities and expected results represent also a new step in the field of research and development of converter technology in the Republic of Croatia. By production of the tramway propulsion converter with energy storage units, the production assortment of the project applicant, KONČAR – Electronics and Informatics Inc. will be enlarged, thereby enabling the appliance and appearance in markets that explicitly require the use of this technology. When developing the energy management algorithms, within the converter and at the vehicle level, it will be necessary to explore and apply new knowledge which will result in multi-sectoral performance (additional development of monitoring, diagnostics and networking using newer and more modern processor modules on the converter).
