System Islanding Using a Modern Decoupling System

The Gulf Petrochemical Industries Company (GPIC) plant in Bahrain produces ammonia, methanol, and urea. The GPIC process load is primarily steam driven; however, 24 MVA of critical loads are electrical, including the ammonia plant. One on-site combustion gas turbine is run in parallel to a connection to the local utility for a highly reliable power system configuration. GPIC requires the ammonia and  methanol plants to be islanded as soon as possible for external system disturbances.

Speed of Line Protection – Can We Break Free of Phasor Limitations?

Today's relays are predominantly based on phasors, and as such, they incur a delay associated with the full-cycle observation window required for accurate phasor estimation. This paper discusses a number of protection techniques based on incremental quantities and traveling waves that significantly speed up line protection.

Performance of Time-Domain Line Protection Elements on Real-World Faults

Ultra-high-speed line protection is becoming a reality today, giving the industry a way to trip line faults in a few milliseconds. One relay described in this paper that uses time-domain principles incorporates incremental-quantity (TD32) and traveling-wave (TW32) directional elements in a communications-assisted tripping scheme, incremental-quantity distance element (TD21), and traveling-wave differential element (TW87). This paper introduces these time-domain line protection elements, shares key details of their implementation in hardware, and illustrates their operation using real-world faults and digital simulations. By comparing the performance of the time-domain line protection elements with the traditional phasor-based elements of the in-service relays that captured the fault records, we demonstrate the performance of the time-domain lineprotection elements.
