Backup Power: UPS, Batteries and Generators

What you'll learn

• Explain utility power disturbances and the ITIC curve, compare UPS topologies, and size UPS capacity, modules and bypass arrangements
• Compare utility service arrangements, interpret reliability statistics, and assess voltage sags, harmonics against IEEE 519 and large-load ride-through requirements
• Select and size lead-acid and lithium-ion batteries for UPS duty, and apply monitoring, ventilation and fire safety requirements
• Compare AC, −48 V, 380 V DC and high-voltage DC distribution, and size rack battery backup units and storage for smoothing AI power swings
• Rate and size diesel generators for data centre loads, plan fuel storage and testing, and explain emissions regulations
• Evaluate battery energy storage for peak shaving and grid services while preserving backup reserve, and compare on-site generation and microgrids
• Describe transfer switch types and sequences of operation, and explain synchronizing, load sharing and load shedding in paralleling switchgear
• Analyze fault current from utility, generator and UPS sources, and coordinate protection, grounding and arc flash across operating modes
• Compare N+1, 2N, distributed redundant and block redundant architectures and calculate loading and availability
• Plan commissioning from factory tests to integrated systems testing, and interpret battery capacity, load bank and transfer test results
• Apply maintenance strategies, monitoring, methods of procedure and emergency procedures to keep backup power reliable
• Design a backup power system for a mixed AI and conventional data hall, sizing generators, fuel, UPS and storage and assessing reliability and sustainability
