Our portfolio

MAIN AREAS OF OUR INTEREST
1.
Calculation and optimisation of electric power systems operation
Calculation of electrical quantities (calculation of normal and fault voltages and currents, powers, electrical losses and so on), optimisation in electric power engineering (electrical losses minimisation, minimisation of unrequired reactive power flows, optimisation of maximum reserve capacity, optimisation of the utilisation of electricity from PVE and so on).
2.
Measurement of electrical quantities and power quality
Measurement of electrical quantities (with recording duration from minutes to years) for further analysis and processing, measurement and evaluation of the level of power quality (voltage quality) in accordance with applicable operation rules and standards, calculations of the customers’ impact and the impact of sources on the grid, design of reactive power compensation and so on.
3.
Development and creation of software products
Creation of computer models of electrical networks (or electric power systems), including computer visualisation of company electrical systems and the development and creation of computer applications to solve various tasks in electric power engineering meeting customer requirements.
4.
Studies, training and consultancy in the field of electric power engineering
We offer analysis of possible causes of various phenomena or events that occur in electric power systems based on a rigorous approach using both theoretical and practical knowledge; technical consultancy in the area of designing new electrical equipment as well as optimisation of the existing electrical equipment operation; consultancy, lectures and training for you and your employees.
