Power Management System

Ingeship Power Managenent System

Power Management System is an essential part of the automation and electrical systems on marine vessels, especially in those with electric propulsion. The PMS controls the power system in order to maximize the blackout prevention capabilities and decrease the maintenance costs due to the protection of the equipment against faults and malfunctions.

• Precautionary genset start
• De-load before opening generator/bus-tie breakers
• Fast load reduction (analogue power limitation set point to the drives, 100ms response time)
• Configurable blackout recovery
• Advanced Load dependant start-stop
• Secured operation (load reservation)

Load Control

• Load transfer (for synchronization, the loading and load sharing)
• Load dependant start-stop
• Manual/automatic load control
• Gensets priority selection, manual, dynamic.
• Heavy consumers management with pre-programmed sequence

Bus bar Section Control

• Configurable power management rules for each section
• Bus-tie and shore connection breakers control
• Active power (kW) load sharing (GOV)
• Load sharing options for each bus bar

Load Sharing

• Load sharing between gensets over the DEIF PPM 300 network
• Equal load sharing, symmetrical
• Asymmetric load sharing for gensets
• One genset base load with asymmetric load sharing for the other gensets
• Shaft generator base load and asymmetric gensets load sharing
• Shore connection base load and asymmetric gensets load sharing

All the controllers work together as a single PMS system with distributed functions:

• Gensets Controller functions
• Bus-tie Controller functions
• Shore controller
• Emergency Gensets Controller functions
