Abstract
Nowadays, the industry is facing an increasing number of appealing challenges. The most critical part is to compete in the market by figuring and shaping the new technology revolution. Along with the Fourth Industrial Revolution, the future power delivery orientation has shifted from generating and distributing electricity to continuously delivering with a high-reliability index.
A dependable electrical system requires a flexible maneuver in the distribution network and a credible protection system. The development of the network scheme and inclusion of the renewable energy resources can be used to efficiently reduce losses in the feeder and provide a contingency scenario, while reducing the sensitivity and accuracy of the conventional protection system.
Therefore, a breakthrough is required to develop electrical protection devices or even systems. Future apparatus must be intelligent enough to work in any network topology and classify events based on a multi-parameter perspective. To do that, boundaries with multi-variable considerations should be determined. Then, these boundaries should be included in the optimization process of coordinating protective equipment to minimize the electricity outage and avoid the false trip issue.
This work investigates the above-mentioned challenges and offers practical solutions to consequently improve the power system reliability and resiliency. An improved method to recognize load characteristics is included during the optimization process of protection relay settings. To attain the minimum tripping time of the protection relay, the combination of the relay curve and load characteristics is introduced. Moreover, the relation of voltage, current, and frequency is investigated to understand power system events and design a novel protection relay architecture. The proposed solutions are tested and verified on various systems, including an Institute of Electrical and Electronics Engineers (IEEE) test system and a real plant application. The proposed solution is expected to evade the false trip problem and adapt to electrical conditions that might happen in medium-voltage industrial power system networks and support the development of the Fourth Industrial Revolution.
