EMT Training - 27 Sep 2019, Auckland
This one day course presents practical modelling and simulation of electromagnetic transient phenomena including transformer energisation, capacitor bank transients, lightning surges as well as rectifier and inverter models. 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. Topics covered include:
PF-3-40 - Introduction to time domain simulations for EMT studies
- The two different types of time domain simulations and when to use each one
- How to initialise a time domain simulation
- How to define EMT variable sets for recording
- How to define plots to show recorded results
- How to define simulation events
- How to run an EMT simulation
PF-3-42 - Transformer inrush simulations
- How to create a transformer energisation event
- How to define transformer saturation curves in PowerFactory
- Impacts of transformer inrush
- Transformer saturation theory
PF-3-43 - Capacitor switching transients
- Electrical transients caused by switching of capacitor banks, and PowerFactory tools for their assessment
- Effect of network impedance on switching resonance (voltage magnification).
- Switching transient assessment and mitigation.
PF-3-44 - Lightning surges and surge arrestor selection
- Lightning transients background
- How to model a transmission line considering explicit earthwire representation.
- How to model a direct lightning stroke to line phase conductors.
- How to model a direct lightning stroke to the earthwire.
- How to implement a surge arrestor to absorb the lightning stroke energy.
Note that places on the course are limited to 10 and allocated on a 'first come, first in' basis. A minimum of six participants is required for the course to run. The course will be confirmed via email no earlier than two weeks prior to the start date.
