Nuclear plants in the United States are governed by federal regulations requiring that the electrical power system provide sufficient capacity and capability to the nuclear plant. As part of this analysis, traditional approaches to manually perform single motor start calculations can be tedious and time-consuming. Also, the manual evaluation of the data can easily introduce errors. This presentation takes a closer look at degraded voltage relays (DVRS) and an approach to simulation used by the TVA that is holistic, using ETAP to easily combine the study cases, the revisions, and the configurations into repeatable studies. The demonstration includes the use of an efficient solution using Python code with ETAP to run the studies and evaluate the resultant data.

Key topics include the implementation of NETPM, focusing on user roles, permissions, and effective workflows. A customer success story illustrates the tangible benefits of NETPM, including reduced man-hours, faster information transfer, and improved risk mitigation. The presentation also covers important considerations for model management, data access, and adapting service models to incorporate NETPM effectively. By emphasizing the shift from static diagrams to dynamic, collaborative models, this talk aims to showcase how NETPM can enhance safety, reliability, and efficiency in power system management. It concludes by encouraging audiences to explore NETPM's potential in their operations, positioning it as a crucial tool for navigating the complexities of modern electrical systems.
The Abu Dhabi National Oil Company, also known as ADNOC, is the state-owned oil company of the United Arab Emirates, and is the world's 12th largest oil company by production. ADNOC is committed to sustainability and has implemented various initiatives to reduce its carbon footprint, enhance operational efficiency, and support the UAE's goal for renewable energy and climate change mitigation. For ADNOC’s many facilities, whether independent power plants or other electrical networks, the challenge is how to provide training to operators, to not only get familiar with the operation management tools and procedures, but also to gain experience with the system response. In this presentation, ADNOC will demonstrate how they use ETAP Operator Training (eOTS) with ETAP Digital Twin as their training environment for the existing power management system to ensure well-trained operators for their electrical networks, turbines, and generators, and to ensure they are capable of responding to any operating scenarios they face on a day-to-day basis, during a plant startup or shutdown, or any kind of disturbance in the electrical network.
In most cases, SCCAF (Short Circuit Coordination Arc Flash) studies are done by engineering firms, which then submit reports to facility owners. The challenge is that those reports tend to be lengthy (up to 5,000 pages), not engaging, and hard to grasp for facility personnel. ETAP's powerful graphical and presentation tools can help make those reports livelier, informative, and more engaging. This case study will discuss how you can summarize lengthy power studies reports within just a 30-minute interactive meeting, and highlight how the final ETAP model can be used, with its powerful graphical interface and presentation tools, including Data Blocks, Multiple Presentation layers, Sequence of Operations, and Arc flash calculator.
This case study discusses the challenges faced by BBraun Medical, a manufacturing facility of medical products, due to unplanned outages and the lack of an optimized load shedding system. This demonstration discusses the use of ETAP Real-Time Intelligent Load Shedding (ILS), and ETAP's digital twin modeling capabilities, to distinguish between different subsystems and validate the ILS solution. The ILS solution provided a quick response to islanding conditions, ensuring the continuous operation of critical loads while shedding non-critical loads, thus minimizing production loss during outages. The solution also offered load optimization, flexible load priority modifications, and real-time monitoring capabilities. Overall, the ETAP ILS solution helped BBraun Medical operate safely during disturbances and minimize the impact of utility disturbances, providing an effective load shedding solution.
The escalating demand for fleet electrification across the U.S. presents a significant challenge to existing distribution infrastructure, necessitating EV charging management strategies to meet electrical energy demands and address power quality issues. Level 2 and Level 3 EV chargers, equipped with power electronic converters and PWM technology, generate non-sinusoidal currents, exacerbating power quality concerns at individual sites. The effect of rapid voltage changes (RVC) introduced by this equipment is also discussed. This case study features insights and observations from field-recorded measurements of unbalanced (per-phase) harmonic distortions at a site with over 300 electric van charging stations. The unbalanced harmonic analysis (UBHA) conducted by Eradeh Power Consulting using ETAP Software for the site, revealed distortion limits being exceeded for individual phase currents and voltages as well as power distribution equipment rating overloads (such as transformer K-rating and cable thermal limits). The presentation also discusses how unbalanced harmonic distortions calculated within the site and at the point of common coupling (PCC) can be mitigated using techniques such as the use of active / passive harmonic filters amongst others.
Engineers face unique challenges when calculating DC Arc Flash incident energy for Battery Energy Storage Systems (BESS). Battery short circuit current is highly variant, and factors such as battery chemistry, and how the installation arrangement of BESS have significant differences in short circuit behavior. As well, traditional methods of calculating DCAF have been determined to fall short when it comes to BESS. In this demonstration, these variations will be discussed, including PPE considerations. Following this, a demonstration of the Transient DC Arc Flash solution provided by ETAP solutions will be presented. The presentation will show the usefulness of model validation, and the importance of high quality analysis methods to provide better accuracy in DC AF analysis for BESS.
