Network calculation

Network calculation is an important step in the planning and analysis of electrical networks. It comprises various methods and techniques for calculating current flows, voltages, load distributions and other important parameters in a network.

Load flow calculation: This includes the calculation of current flows and voltages in a network, taking into account loads, feeds, network configuration and operating conditions.

Short-circuit current calculation: This refers to the determination of the maximum short-circuit current at various points in the network in order to correctly dimension the protective devices.

Voltage drop calculation: This calculates the voltage drop along the lines and at the nodes in the network to ensure that the voltage is within acceptable limits.

Network stability analysis: This analyses the stability of the network under various operating conditions to ensure that the network can react appropriately to faults or load fluctuations.

Power flow optimisation: This includes the optimisation of operating parameters such as power factor, load distribution and grid configuration in order to improve the efficiency and reliability of grid operation.

Integration of renewable energies: The integration of renewable energy takes into account various aspects, such as the intermittent nature of renewable energy sources and their impact on load flow and grid stability.

The network calculation is carried out using computer simulation programs that use complex mathematical models to analyse and optimise the behaviour of the network under different scenarios. These calculations are crucial for the planning, operation and further development of electricity grids in order to ensure a reliable and efficient power supply.
