System is equiped with: two channel digital voltage regulator, fully redundant thyristor power converters in 1+1 configuration, DC field circuit breakers and rotor overvoltage protection. It is suitable for large hydro and turbogenerators. The static excitation system is based on a robust modular design, engineered and designed to meet all modes of operation of large synchronous generators. The system is characterized by high accuracy, reliability and speed. The main characteristics of this system are: dual-channel redundant configuration, automatic voltage regulator, adjustable PID type, excitation current regulator, higher-level control functions (the reactive and active compensation by current generator, the Power Factor Controller / cos (φ) regulator, embedded power system stabilizer (PSS) ), integrated limiter functions, logic and sequence control, the possibility of extending the digital and analog inputs and outputs.

KONreg S1000 with its compact design, small dimensions and integrated power converter is ideal solution for brushless and small synchronous generators, motors and motor-generator sets. It supports a number of communication protocols and in itself has built several communication interfaces. In conjunction with embeded software allows regulation up to 25A (40A, 10s) and 375Vdc. The main control loop is an automatic voltage regulator with adjustable PID controller. In addition to that in regulator are implemented other additional control functions such as power factor controller or cos (φ) regulator. Field current regulator of PI type is built in as a stand-by regulator. Synchronization function is also implemented in regulator. System allows easy adjustment of all parameters, supervision of all signals inside system and waveform capture (record) through a personal computer and the HMI device.

KONTRAC GP 550 AC converts the power from transformer outputs of AC network into propulsion power for the traction motors. It has sinusoidal input current in phase with voltage and with low harmonic content. During braking, the converter feeds back energy to the network. All control, protective, communication and monitoring functions are implemented in one control electronics inside the converter.

Latest project ・ 24 Jan 2018 read more Open In New icon

During December 2017, Končar – Electronics and Informatics engineers as a subsuplier of Končar – Generators and Motors Inc. commissioned new static excitation system type BKN 11E with excitation transformer, for the generator 1 (6,1 MVA) on HPP KORKEAKOSKI, Finland. The first unit of this power plant was commissioned earlier by Končar in February, 2017. For the project, KONČAR has designed, engineered, manufactured and supplied the generators and excitation systems along with supervisory services during erection and commissioning. At the end of the project, the customer pointed out the pleasant cooperation with the whole Končar team.
