HPP MULUNGUSHI, Zambia – commissioning new excitation systems
KONČAR – INEM as a subcontractor of KONČAR – KET on revitalization of the plant HPP Mulungushi in Zambia put into operation static excitation system type SKB 11 for generators of 8 MVA.
The system is fully adapted to the needs of the customer, which once again confirms that KONČAR’s flexible approach, knowledge and ability of its employees can meet all the technical requirements of end customers.
New DC power supply system for the TS 110/20/10 kV Ksaver
DC power supply system for the TS 110/20/10 kV Zagreb Ksaver was contracted within the project of modification of monitoring, control, protection, and supply systems in transformer substations. The new system in future will supply the following vital equipment in substation:
- protection system, measurement and control of the 110 kV facility,
- all drives for disconnectors, earthing switches and electro-hydraulic 110kV breakers,
- substation computer,
- emergency lighting,
- remote control equipment and
- telecommunications equipment.
DC power supply system KONIS-B 220 V, 40 A, 170 Ah is designed and manufactured by a high requirements and standards of HOPS (Croatian TSO) for UPS systems with DC voltage. The system consists of the following main parts: four modular rectifiers BFS, the control unit KONLOG, the battery pack 170 Ah, housed in two cabinets, battery protection and DC voltage distribution. In order to ensure the speedy and effective local control rectifier cabinets and distribution are provided with direct access, without doors.
Testing required characteristics and equipment quality was successfully carried out in the test station late February in the presence of investor representatives.
New excitation system for new hydro power plant – HPP Brežice, Slovenia
Two weeks ago, KONCAR- Electronics and Informatics engineers commissioned second static excitation system type SEB 11E with excitation transformer, for the generator 2 (21.5 MVA) on HPP Brežice in Slovenia. Excitation system is implemented in the dual-channel version with bridges in 1 + 1 configuration, which provides full redundancy of the system.
First system for the generator 1 was commissioned in January and during this year the plan is to install and commission last excitation system for generator 3.
