Power System studies may include Protection Coordination studies, Load Flow and Short Circuit analysis, Arc Flash Safety analysis, and more complex scenarios such as Transient analysis for stability, and Harmonic analysis for power quality.
Power System and Protection Coordination studies are not limited to greenfield sites. Sporadic plant expansion or upgrades over many years with no new protection coordination design often result in overloaded feeders, inappropriate settings and major unnecessary power losses for minor problems. In such cases, the protection coordination study needs to be revisited with a site-wide review to improve the safety and reliability of the system.
