⚖️ load shedding & power strategies

kW/kVAr control · Priority · Shedding · Restoration

✓ Isochronous load sharing – kW (real power) via CAN/LAN
✓ Droop control for legacy systems & parallel with shore
✓ Automatic load dependent start/stop – optimum efficiency
✓ Load shedding – priority based (ANSI 81) – non-essential trips
✓ Heavy consumer blocking & ramp control – prevent overload
✓ Power factor control (kVAr sharing) – AVR setpoint adjustment
✓ PMS integration with Propulsion Control / IAS – Kongsberg, Norcontrol, Lyngsø, Valmet
✓ Generator protection against reverse power, overload, overcurrent
✓ Bus transfer (AMF / mains failure) – seamless or delayed
✓ Blackout recovery sequence – auto start & sync of standby genset
✓ Analog / digital I/O expansion for old switchgear
✓ SCADA visualization – touch panel, PC, web
✓ Historical data logging & trend analysis
