Abstract

Protection
coordination is the heart of all power systems. To insure a quality and
reliable operation of the power systems, an electrical fault must be cleared
within short time. This can be achieved by proper coordination between the
protection relays. In Siddik Kardesler Substation the MV voltage feeders’
protection is provided by overcurrent relays. This paper is principally
concerned with practical protection coordination of the electrical substation
by using substation as case study. In the Part-2, distance and differential
protection will be discussed. Finally, after test and commissioning, the
substation is successfully energized without problem.
