KONCAR - Electronics and Informatics Inc. products

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. KONreg S1000 supports a number of communication protocols and in itself has built several communication interfaces. This kind of design in conjunction with software allows regulation up to 25A (40A, 10s) and 375BVdc.

Static excitation system with KONreg digital voltage regulator was built around powerful, programmable processor unit, which allows the execution of regulation and control in real time, with fast response, high accuracy and reliability. The system is designed so that it can be completely customized to customer requirements, both for new facilities / projects and for reconstruction of the existing ones. The system consists of excitation transformer, digital voltage regulator in a single channel version (dual-channel version is available on request), thyristor converter (1 + 1 or n + 1 configuration-on request),de-excitation circuit (DC or AC), overvoltage protection, and field flashing (from DC or AC power source). Also, at the request of the customer, within our system we can supply equipment for the electrical braking.

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. Equipment is fully adapted to all operating modes of generator excitation regulation system, protection and communication, according to all important communications protocols.

KONvert static frequency converter is a device developed for the direct transfer of energy produced by wind turbine using hardware power electronics. Universal, robust design and reliable operation, are the features of this modern products that can be applied in addition to a frequency converter for the wind turbine, to transfer energy on small hydro power plants, reversible (storage) hydropower plants, as well as a device for dynamic reactive power compensation applicable in the industry.

Equipment and solutions we offer are custom design and installation of equipment according to the individual customer’s needs, with the highest degree of operational safety and efficiency, environmentally friendly, high-performance, reliability and quality, long life and flexibility. We offer, in the early stages of the project, feasibility studies,  the initial calculation of hydrology and annual production. We consider our customers as partners in the project and we offer the service of preliminary, main and detailed design, assistance in obtaining various approvals and permits.

The most important energy facilities (thermal and hydro power plants, large transmission substations, etc.) should have the highest possible reliability of power supply because the possible damage caused by a power supply failure at a critical moment can surpass by far the price of power supply. The right choice for such facilities is redundant parallel connection of two completely independent power supplies. Thereby independent double supply of each load or a small group of loads is provided. Redundancy of cables themselves is often applied. High reliability is based on the requirement that the failure of one system does not in any way affect the operation of other system, which continues to supply all loads without interruption. DC power supply system 2xKONIS-B consists of two completely independent power supplies KONIS-B, configured in a redundant parallel system.

Bay terminal RFX combines the functions of protection, control, measurement and monitoring in the field of a power plant. HMI design allows the display of a single pole bay diagram with the status of all apparatus, logical blocking of the apparatus and display of current electrical values. RFX offers a complete range of protection functions required for a reliable protection of medium voltage, as well as points of connection for distributed sources.
