Explore how ETAP can assist in meeting European directives for arc flash studies and understand the distinctions between North American and European electrical safety standards, offering crucial insights for professionals.
Explore how outdated Arc Flash Study findings were overcome by utilizing ETAP software to update equipment data, validating short circuit currents, and generating fresh Arc Flash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.
The Red Sea Utility Grid is in the Tabuk province of Saudi Arabia. The site is a vast 33,000 km2 of islands, lagoon, coastal plain and mountains with extremely diverse marine life and terrestrial landforms. The grid is divided into four off-grid microgrids. The focus of this presentation is about three of the microgrids that are very similar in size and operation. Each of these microgrids includes two PV generation (total 6 MW), two battery storages (total 5MW, ~18 MWh), and two emergency backup diesel generators (~ total 3.8 MW). The system is designed to achieve high reliability by having redundancy at various levels.
Arc flash analysis extends well beyond the scope of IEEE 1584 and NFPA 70E methodology for transmission, distribution and renewable energy systems. For many years, the industry has been lacking an “all-in-one” solution for performing arc flash analysis on DC, LV, MV and HV AC systems. ETAP ArcFault™ provides a validated method for performing arc fault simulations in T&D open-air overhead conductor systems plus it provides two methods to determine the incident energy for arc-flash in 3-phase enclosed equipment for 15 to 38 kV renewable energy collector systems. This presentation explains the background and methods for arc fault simulations and explains how ETAP ArcFault helps utilities comply with OSHA requirements to perform arc-flash analysis for systems voltage above 1.0 kV.
Cities of the future will soon account for 90% of the world’s population growth and 75% of its energy consumption. The pressure on critical resources will increase. The New Administrative Capital in Egypt launched one of the country’s most ambitious development projects to date, setting standards in smart city living. ETAP GRIDTM ADMS solution will manage, control, visualize and optimize power distribution required to run critical smart services for city operators, citizens, workers, and visitors alike. Learn how ETAP distribution management is utilized to support long-term sustainable, efficient smart city services that will support a safer, more innovative, and more prosperous Egypt.
How a failure, to properly perform protection studies, led to a significant substation safety incident and outage. Understanding minimum and maximum fault current values are critical in this case study. The shortcomings led to a fault not being removed fast enough. Short circuit impedances are very valuable, it is critical to have the right cables and impedances of the equipment. An excellent learning from this case study is that line to line arc flash fault exists much longer at medium voltage level. In low voltage we do not see those type of line-to-line arc flash faults because line to line arc flash fault will rapidly turn into a three-phase fault. The arc flash calculator is a great tool to estimate incident energy. The arc flash calculator shows both methods: below 15 kv we can use IEEE 1584-2018 to calculate incident energy at 15 Kv, and above our fault calculated method can calculate calories exposure during the fault.
A practical example of an internal review of a protection coordination study, including the definition of protective device settings & characteristics.
Design and commission of a green-site power system including protection coordination for the entire site and implementation of IEC61850 communications, inter-tripping, inter-locking and protection blocking schemes.
Konexa rolling out its integrated distribution model with multiple DISCOs across Nigeria. In its sub-concession area, Konexa will develop embedded generation capacity (solar PV), and invest in the distribution network (medium voltage line, distribution transformers, injection substations) and last mile reticulation (low voltage lines, smart metering infrastructure). In addition, Konexa will invest in and implement IT & OT systems and processes to drive operational efficiency and significantly reduce ATC&C losses. The first phase of the project would serve about 7,000 customers (C&I and residentials).
