Automated Application Oriented Testing using Real Power Network Models for Combined Protection and Control Systems

Abstract

The development of more intelligent and smart medium and low voltage grids leads to the introduction of more complex combined protection and control systems. The conventional testing methodologies for protection relays are not sufficient for the validation of combined protection and control functionalities. Therefore, the concept of application oriented testing was already proposed in previous work. This concept has to face two challenges: the real time simulation model generation and the automation of the test procedure. These challenges are solved by the implementation of a new automated grid building algorithm based on real grid topology data and the automation of the test execution using python scripting language.
