Short-Circuit Analysis in ATPDesigner

In ATPDesigner the short-circuit analysis will be also called Load Flow Calculation 

The network simulation program ATP is able to process a steady-state analysis of electrical power grids, which can be also called Phasor Solution. The aim of a steady-state grid analysis is the calculation of the complex phasors of voltages and currents of all nodes of the power grid, in addition apparent power S, active power P and reactive power Q. The results of the steady-state analysis of the power grid are the results of the ATP SteadyState Analysis according the ATP Rule Book.

ATPDesigner uses the ATP to execute the Steady-State Analysis of power grids, reads the results out of the .LST-file, analyzes the results and displays these results as Short-Circuit Analysis Results as well using a spread sheet as using the tooltip technology "at the tip of the mouse cursor".

ATPDesigner reads the .LST-file and identifies the voltages and currents which correspond to the equipment used in the power grid. Therefore not 100% of the calculated steady-state analysis data saved into the .LST-file will be presented by the Short-Circuit Analysis Results, but only a subset of those, which correspond to the nodes of the equipment of the power grid.

Transient Behaviour of Short-Circuits

ATPDesigner in conjunction with the ATP can also simulate the time-dependent behaviour so called Transients with and without short-circuits and can display electrical quantities such as voltages v(t) and currents i(t) in diagrams. The time at which the short-circuit occurs and the time at which it is cleared can be set according to the user’s requirements.
