Phase 45: Power Management, ELICS & Generator Synchronization
This phase contains 3 sections and 24 checklist topics. Use the interactive phase page to track your own learning progress.
45.1 Power management system (PMS)
- What is a PMS and why plants use it?
- Generator, incomer, busbar, bus coupler and outgoing feeder
- PMS components: meters/IEDs, controller, SCADA and breakers
- Normal electrical load versus critical load
- PMS alarm and event monitoring
- Electrical load prioritization and available capacity
- Basic kW, kVAR, PF, frequency and voltage monitoring
45.2 Electrical load/control systems (ELICS)
- What ELICS means in this specific JD and why names vary by employer
- Load permissives and operating interlocks
- Load-shedding conditions and priorities
- Fast/slow load shedding awareness
- Automatic restoration and operator approval concepts
- Fault simulation: generator lost, frequency drops, load disconnected
- Interface among PMS, PLC, IEDs and SCADA
45.3 Generator synchronization and power distribution
- Why generators must be synchronized before paralleling
- Voltage magnitude matching
- Frequency matching
- Phase sequence and phase angle
- Synchronization permissives
- Synchronizing check relay (ANSI 25) awareness
- Circuit breaker closing interlock concept
- Generator real/reactive load sharing awareness
- And 2 more checklist topics
