Understanding Power System Response
Three critical power system operational considerations are fault recovery, fault induced delayed voltage recovery (FIDVR) and cold load pickup (CLP). This course provides the background to understand and address FIDVR concerns, CLP events, and how the power system responds when short circuits occur.
Benefits and Learning Outcomes
- Examine the effect of reduced voltage on motors, heaters and power supplies
- Learn the response of ancillary items – protective relays, voltage control devices.
- Discover the use of templates to evaluate load response during FIDVR events and CLP events.
Upon completing this course, you will have an understanding of the impact of fault voltage and fault duration on fault induced delayed voltage recovery and the impact of time of year and outage duration on cold load pickup (cold load pickup is the nomenclature used to describe what happens when voltage is restored after a prolonged outage).
