The grid calculation program ATPDesigner is a graphical user interface for the calculation of voltages, currents, powers and various mechanical parameters in power grids, which uses the grid calculation program ATP (Alternative Transients Programwww.eeug.org). The interface between ATPDesigner and ATP is established via text files. During the calculation, ATPDesigner generates an .ATP output file that contains all the necessary data of the power grid and can be calculated by ATP. Thus, it is not necessary to deal with the complex set of rules of the ATP grid calculation programm. As a result, ATP delivers an .LST file (load flow results) and a diagram file (.PL4 file).

ATP is a worldwide used software tool for the calculation of especially 3-phase, electrical power supply networks. With the help of the ATPDesigner program as a graphical user interface, even complex and extensive electrical power supply networks can be set up and calculated in a simple way. Detailed knowledge of the ATP-specific regulations is not required.

ATPDesigner contains all important electrical power supply equipment, such as transformers or lines, as templates. The physical properties of the equipment can be changed and thus adapted to the respective operating conditions. Due to the simple selection of the desired equipment and the simple connection options of the equipment to each other, even large electrical power supply networks can be quickly created and calculated. With the help of ATPDesigner, it is also possible to calculate network faults such as short circuits. The results, i.e. voltages, currents and power, are displayed for the individual resources in tooltips or in the network graphic.

ATPDesigner can examine the power grid with the ATP calculation kernel in its steady-state as well as in its transient behaviour. ATPDesigner is therefore particularly suitable for the analysis and evaluation of short circuits in power grids, but also for load flow calculation.

Protection Relays in ATPDesigner

The grid calculation programm ATPDesigner is especially suitable for the simulation of electricity grids of all voltage levels and the grid protection technology and decentralised generation plants used in them. The numerical models of protection functions implemented in ATPDesigner are generic, i.e. manufacturer-neutral models.
