A Comprehensive Approach to Protective Device Coordination
The design, sizing, and regulation of the protection system are still one of the major challenges for the integrity and continuity of operation of the power system despite the continuous technology evolution. Protection system shall be capable to continuously monitor the power system, operate quickly and selectively under hundreds of transitory conditions for any type of fault without false trips with the objective to minimize outages, improve safety, and maximize service continuity. This presentation covers a real case study for an expansion of a brownfield industrial installation with new equipment that prompted the need for modification of existing protective device settings thus, requiring revision and re-validation of the coordination studies. The case study will demonstrate how ETAP software features and capabilities were utilized to verify the new / recommended settings to address the protection & coordination objectives and arc flash hazard impact.
ABB FCL Application Engineering for IS-Limiters
This presentation will feature covert ABB Fault Current Limiter (FCL) application engineering for Is-limiters. We will explain the fault current limiter technology by using the well-known ABB FCL Is-limiter. The FCL technology will be introduced, how it clears a short-circuit fault current compared to a standard circuit breaker, and the major components of an FCL. The theory of the application engineering process and the calculation of the tripping value for an FCL will be introduced. Based on an actual customer project, it will be shown how ETAP has facilitated the complex FCL application engineering, and examples will be provided of how the real tripping value for a fault current limiter is determined. The session will conclude with an overview of how etap can already be used today for an FCL application engineering and what will be enhanced in the future.
Protection & Selectivity in Industrial Facilities
PETRONAS RAPID project is the largest oil & gas refinery and petrochemical plant in Malaysia which is powered by a 1200MW utilities plant and connected to a 275kV Grid supply. The integrated ETAP model for the RAPID complex reached up to 5000 buses that consist of various distribution voltages from 400V up to 275kV. Protection Coordination evaluation study for the RAPID complex was performed using “PD Sequence-of-Operation” to identify abnormal relay behavior, which may not be observed in the conventional TCC curve. When simulating earth fault at 275kV system, there is sympathetic relay operation at all 275kV healthy feeders due to circulating earth fault current. The circulating earth fault current is more than 1pu, which will potentially cause a broader outage to the RAPID complex. Further analysis has been performed by the author and academician experts to ascertain the root cause of the circulating earth fault current. This presentation will discuss the root cause of sympathetic relay operation during 275kV earth fault simulations and the recommended solutions to mitigate the sympathetic operation. This will help engineering design firms and plant operators clearly understand the protection relay behavior during faults by utilizing ETAP special features.
