Laboratory: Implementation of Automation Functions for Monitoring and Control

  Sketch

The Institute for Automation of Complex Power Systems (ACS) at the E.ON Energy Research Center offers students an online automation laboratory course entitled "Laboratory: Implementation of Automation Functions for Monitoring and Control". This course module is regularly offered in the summer semester. This course is worth 4 credits (120 hours) and is held in English. The learning objectives, module details, and the course evaluation procedure are explained by Prof. Ponci in the kick-off session. The following concepts are covered in this course:

 
  • to understand and apply the basics of IEC 61850
  • to configure and integrate Intelligent Electronic Devices for monitoring, distribution and protection functions
  • to validate the IED and substation configuration

The above-mentioned concepts are elaborated more in the following LAB sessions:
