Calculation and optimisation of
electric power systems operation
Calculation of levels of electrical quantities for various configurations or calculation of parameters of devices of investigated electric power systems is an essential part of the design of new electrical devices or the analysis of the operation of existing electrical devices. In some cases, it is the only way to test the immunity of a given electrical equipment to operate in specific situations.
We offer the following services within the calculation of electrical quantities
- calculation of voltage and current conditions during steady-state operation,
- calculation of the maximum short-circuit currents for dimensioning devices and the minimum short-circuit currents to design protection relays settings,
- calculation of voltage drops, power ratios and electrical losses,
- calculation of electrical quantities for the design of generator switches,,
- calculation of earth fault currents,
- calculation of step and touch voltages,
- calculation of assumed values of voltages and currents at the moment of start-up and during start-up of drives,
- calculation of instantaneous values of voltages and currents during transient events (e.g. when a ground fault occurs),
- calculation and mathematical simulation of assumed frequency value during system failure.
Optimisation calculations in electric power engineering
If required, we are able to determine an optimal solution to your various tasks. Optimal solutions to your tasks can save your time, material, money and energy.
Here are some of our services from the field of mathematical optimisation:
Here are some of our services from the field of mathematical optimisation:
- optimisation of the operation or maintenance costs of individual electrical equipment, optimisation of the operation of the electrical network in order to achieve electrical losses or voltage drops as low as possible,
- optimisation of the maximum reserve capacity value agreed between the customer and the power distribution company,
- optimisation of the size and number of steps for load shedding,
- identifying potential possibilities of the photovoltaic system usage and the system of storage of electrical energy to reduce the costs of purchasing electricity at predicted electricity consumption, determining the expected return on investment,
- determination of the estimated amount of solar energy incident on the area of photovoltaic panels in a given area during the year, taking shading of surroundings into account, and optimisation of photovoltaic power and battery capacity for predicted electricity consumption.

Measurement of electrical quantities
and power quality
Measurement of time courses of individual electrical quantities represents one of the basic diagnostic methods, either for the purpose of identification of possible cause of unwanted cases in the network or for the verification of voltage quality or stability at a measured point.
We offer the following services in terms of measurement of electrical quantities and power quality:
Measurement of electrical quantities and power quality analysis
- short-term (from minutes to hours), medium-term (from days to weeks) and long-term (from months to years) measurement of electrical voltages and currents in order to analyse and visualise them, or for their statistical processing and use in calculations, etc.,
- measurement and evaluation of the level of power (voltage) quality in accordance with applicable operation rules and standards,
- elaboration of voltage quality protocols,
- proposal of measures to increase the level of power quality, or to prevent the effects causing outages or incorrect operation of electrical equipment that is sensitive to a reduced level of power quality,
- calculation of the reserve of qualitative indicators in the point of common connection,
- elaboration of documents for the submission of an evaluation of the power quality standards of electricity distribution and supply of electricity to end electricity customers in accordance with the Regulatory Office for Network Industries.
Calculations of the customers’ impact and the impact of sources on the grid
- elaboration of connectivity studies of new customers or sources of electricity in accordance with the regulations of a relevant power distribution company, or. with the regulations of the transmission system operator of the Slovak Republic,
- determination of the impact of individual subjects or equipment on the overall level of power quality.
Design of reactive power compensation
- measurement of the electricity consumption profile (reactive and active power) for the purpose of optimal design of compensation devices
- examination of possibilities of minimisation of fees for non-compliance with the prescribed value of the power factor, or for unasked supply of reactive power,
- examination of the necessity of tuned compensation,
- calculation of the economic return of the proposed solution.
