Abstract
Development of a Toolbox for Alternative Transient Program Automatic Case Creation and Execution Directly From a Technical Database
Highlights
Studies of electromagnetic transients are essential in planning and operation of electrical grids
The toolbox proposed in this article aims at automating the generation and execution of Alternative Transient Program (ATP) input files, facilitating the execution of transient studies in the routine of energy transmission or distribution utilities, due to the fact of reducing the time required for grid modeling, which is a basic step in most transient analysis of transmission/distribution electric networks
The proposed toolbox validation is made through comparison between the results obtained by using the toolbox procedure and the similar results obtained by running the ATP with the ATPDraw interface
Summary
Studies of electromagnetic transients are essential in planning and operation of electrical grids. The simulations of high frequency transients allow the assessment of lightning strikes criticality in the electric network [1]. It indicates which buses are more sensitive to voltage and current surges and it assists in determining the optimized positioning of surge. Transient simulations can assist in assessing the impacts of inserting components such as long extra high voltage cables, capacitor banks and high voltage DC links, which can cause electromechanical and electromagnetic phenomena with adverse effects on the system, such as temporary overvoltages due to harmonic resonances [5].
