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.
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.
Drakenstein Municipality sought an OEM partner to establish a SCADA Main Station in their Control Centre, supervising the distribution network of the Dalweiding Substation supply area, integrating substation protection and control solutions using the IEC 61850 standard, with ETAP chosen for its digital-twin concept, model-driven approach, and modular scalability, facilitated by Altek Solutions.
Explore how outdated Arc Flash Study findings were overcome by utilizing ETAP software to update equipment data, validating short circuit currents, and generating fresh Arc Flash results aligned with the 2018 standard, providing the client with enhanced safety measures and confidence in their protocols.
Electrical infrastructure can only be managed by including both equipment and data. Transforming electrical data to information and knowledge for decision-makers of mission-critical facilities requires IT-compatible software with the latest technologies’ integration capabilities. This presentation shows how ETAP enables end-users to achieve sustainable operations in their critical facilities by fulfilling OT/Site Management and IT Management requirements. ETAP’s unique features are configured with respect to data center topology and sustainable operation principles. These features are enriched as we have positioned ETAP in the corporate environment of end-users, where their corporate IT standards, services, and tools are integrated. As the title suggests, both OT and IT protocols are commissioned together, and the management of electrical infrastructure is powered by IT services via ETAP.
