Engineers face unique challenges when calculating DC Arc Flash (DCAF) incident energy for Battery Energy Storage Systems (BESS). Battery short circuit current is highly variant, and factors such as battery chemistry and the installation arrangement of BESS contribute to significant differences in short circuit behavior. As well, traditional methods of calculating DCAF may not be sufficient when it comes to BESS. Nexamp Energy studied these variations, including considerations for personal protection equipment (PPE). The Transient DC Arc Flash solution provided by ETAP was also examined to highlight the usefulness of model validation and the importance of high quality analysis methods for providing better accuracy in DCAF analysis for BESS.
Stellenbosch Municipality is a local municipality in the Western Cape province of South Africa serving more than 200,000 customers. They were in search of a capable OEM partner to provide them with end-to-end support in establishing a SCADA Master Station in their Control Centre to supervise and operate their distribution network. Further, they needed assistance to prepare the configuration of the SCADA Master Station system and allow for a completely integrated substation protection and control solution. With the help of Altek 欧美A片 (System Integrator of ETAP in South Africa), this project was executed to meet the customer’s objective. This demonstration discusses the new SCADA Master Station at the Municipal Control Centre, which was implemented in various phases. The first phase was establishing SCADA at the Control Centre and connecting 7 substations. The next phase will be to add-on DMS & OMS capabilities to the SCADA system. ETAP was selected for this phase due to its modular and scalable platform to build on top of the ETAP SCADA system to meet their need of a Distribution Management System easily in future.
Multiple arc flash incident energy mitigation methods are available, but how does an engineer know which is best for their client? This presentation identifies an approach to follow to pick the method, considering effectiveness, practicality, feasibility, and overall best option for realistic study results. With extensive experience with arc flash studies for many clients of all sizes, Mangan provides a real world demonstration of a project for a refinery client. The interplay between motor starting and arc flash analysis was evaluated, and mitigation recommendations were customized for the system. The challenges encountered during mitigation are identified, and the proposed solution is analyzed using ETAP Load Flow, Short Circuit, Arc Flash and Motor Acceleration Analysis. Safe motor operation, safe motor starting and arc flash protection are provided through customized mitigation methods and thoughtful system design.
This Red Sea Project is a groundbreaking endeavor in Saudi Arabia under the Saudi Vision 2030 economic development program. The project is powered by a fully renewable energy system, including large-scale solar photovoltaic (PV) system and a substantial 1.3 GWh energy storage system, effectively providing 100% clean energy to the development. As the Engineering, Procurement and Construction firm for this project, SEPCOIII has been involved with the design and construction of a wide range of permanent utility assets, including support facilities such as desalination plants, power generation facilities and distribution networks for water, electricity and natural gas. In this presentation, learn how SEPCOIII relied on ETAP's Advanced Distribution Management System (ADMS) to assist with the technology challenges for the project’s distributed energy power system, and how the solution is being used to manage and supervise the power distribution system to achieve better optimizations and improve system stability.
ETAP 2024 is here! The integrated design and operation solutions featuring a new user interface designed to maximize efficiency, enhance productivity, and simplify the overall user experience.
Discover the new Feeder Hosting Capacity module provided in ETAP 2024 to support solar PV systems being integrated into modern distribution networks. Incorporating PV arrays into existing feeders presents several challenges, including overvoltage, backflow, thermal overloading, protection mis-coordination, and increased harmonic distortion. To address these issues, it is essential to perform feeder hosting capacity (FHC) studies, which assess the optimal amount and placement of PV installations. By leveraging ETAP 2024's Feeder Hosting Capacity module, engineers and utilities can confidently integrate renewable energy sources into their grids while ensuring optimal performance and sustainability. The three key analysis options provided in ETAP FHC, Nodal HC, Stochastic HC and Impact Analysis are described in detail, along with how smart inverters are addressed.
