Protection Analysis and Stability Training - 10-13 Oct 2017, Melbourne

This course provides a comprehensive introduction to the advanced protection specific tools of PowerFactory and DIgSILENT Simulation Langauge (DSL) for developing time domain (RMS and EMT) models of control systems such as AVR's, governors, Power system stabilisers and STATCOMs. Before attending this course, course attendees should be familiar with the basic use of PowerFactory such as how to perform load-flow and short circuit analysis and navigate around the database.
