Power Management System (PMS)

Høglund PMS performs all normal functions necessary to handle the power generation and main distribution on the vessel, such as: controlling the generators, synchronizer, governors and main switchboard breakers.

Høglund Power Management System (PMS) is known worldwide for its adaptable functions, trustworthy logic and user-friendly operator interface. It may be integrated together with our IAS solution, or installed separately as a standalone system.

PMS Functions

The main parameters in the system are the actual number of generators to be kept connected by the system, and the desired starting order of these engines. When these parameters are altered, the system will automatically arrange the generators, breakers and other components in order to facilitate the desired configuration.

The major PMS functions are:

  • Load dependent start/stop - handles the start/stop of the engine in situations when this is required by the power demand, and contains different programs for load dependent start/stop of generators
  • Pre-warning alarm - a function which automatically starts the next available generator if any engine conditions which will lead to a shutdown of the engine is getting critical near the shutdown limit
  • Shut down function - when an engine shutdown is detected, a signal is sent to the PMS which will immediately disconnect the breaker and start the next generator in the sequence
  • Load reduction - each thruster drive will get an available power signal from the PMS, and the system will prevent the generators from overload, and reduce the risk for a total blackout in case of an unpredictable generator trip, in a sudden critical maneuvering situation.
  • Heavy Consumers -  Controlling start of heavy consumers by looking at connected and available power on the switchboard. Starting new engine / connecting new generator if needed.
  • Blackout - handles both partial and total blackout, and reconnects important breakers after blackout
  • Switchboard configuration - configuration of tie breakers/swb breakers depending on operational mode.
  • Active Load sharing – The load sharing mode is normally isochronous, where the governor is handling the load and frequency control. We do also support droop compensated load sharing, were PMS control the engine speed with increase/decrease signals
  • Alarm handling – PMS and SWB alarms will be raised and needs to be reset by the operator

Design Philosophy

The design philosophy is that no failure of any system component shall lead to any changes in the system. In case of any loss of system components, no generators will stop and no breakers will open/disconnect.
