Power Grid Simulation and Protection Relays

The power grid calculation program ATPDesigner is a graphical user interface for simulating voltages, currents, power and various mechanical parameters in electrical power grids, which utilises the ATP (Alternative Transients Program, www.atp-emtp.org). The interface between ATPDesigner and ATP is established via text files. During the simulation, ATPDesigner generates an .ATP-file containing all the necessary data for the power grid, which can then be processed by ATP. This means there is no need to deal with the complex rules and regulations of ATP. As a result, ATP produces an .LST-file (load flow results) and a diagram file (.PL4 file).

The ATP (Alternative Transients Program)

The ATP (Alternative Transients Program) is a software tool that has been used worldwide for decades in industry, research institutes and universities to simulate three-phase electrical power grids in particular.

Equipments in ATPDesigner

ATPDesigner includes the most important equipment required for modelling and simulating electrical power grids, such as transformers and cables, as templates. The physical properties of the components can be modified to adapt them to the specific operating conditions. Thanks to the simple selection of components via drag-and-drop and the straightforward connection options between components, even large electrical power supply networks can be created and calculated quickly. With the help of ATPDesigner, it is also possible to calculate faults in power grids such as short circuits. The results, such as voltages, currents and power, are displayed for the individual equipment in tooltips or in the diagrams as well as in phasor diagrams.

Calculation of Transients and Steady-State Grid Conditions

ATPDesigner enables the behaviour of the power system to be calculated and analysed using the ATP, both in steady-state and transient conditions. ATPDesigner is therefore particularly well suited to the analysis and assessment of short-circuits in conjunction with power system protection relays, as well as for load flow calculations during normal operation conditions.
