Simulation of Power Systems with Inverter-Based Resources & Insulation Coordination Studies - Australia

Simulation of Large Power Systems with IBR & Insulation Coordination Studies using EMTP

Course Outline

The course starts at 9:30 a.m. and ends at 4:30 p.m. There is a lunch break of 1 hour at 12:00.

Lunch is included in the price. 

The course is presented using exercises at each step. The students must build cases and study simulation results. The course emphasizes learning through exercises performed by participants. 

The participants must provide their own computers and will receive a free 30-day licence of EMTP® with all options and toolboxes.
