An example of a power system is the electrical grid that provides power to homes and industry within an extended area. 7 months ago Case Study: Application Considerations in System Integrity Protection Schemes Read Now. Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults through the disconnection of faulted parts from the rest of the electrical network. Case studies usually present a major programme intervention or policy option relevant to the journal field. Introduction. Power system engineers are deal with several challenging problems such as power system operating, planning, and protection. Diffferent Protection schemes 52! You can click “Close” to remove this message. The cases studied are grouped into two catego-ries: power quality case studies and protection and reliability case studies. Where appropriate, we support this advice with statistical analysis of historical protection system fault data.
