AUTO GEN - Power management system

Naust Marine´s Auto Gen Power management system is an automatic electrical system meant to increase propulsion power, reduce oil consumtion and demand for maintainance.

The Auto-Gen system is suitable for upgrading older fishing vessels, that have too small main engines to benefit from the newest fishing technology, - like the ATW system.

The three main advantages of the AUTO-GEN system are:

1.     Increased propulsion power by added auxiliary power through the shaft generator.

2.     By sharing the load of all the diesel engines equally, extreme load on individual engines is avoided. This results in lower maintenance cost and less oil consumption.

With extra equipment the AUTO-GEN may be used as alternative facility to a broken main engine, transferring auxiliary power to the propeller through the shaft generator.

The AUTO-GEN equipment

The main component of the AUTO-GEN system is the SYMAP unit, which controls each generator and links it to the other SYMAP units for smooth synchronous control of the main system, protecting generators and diesel engines.

In addition the system is equipped with Power Management System, controlling the entire main system of the ship.

Three different modes of operation may be chosen from the AUTO-GEN control panel for the shaft generator.

Mode A: Symmetric Load Sharing.
Both/all generators run at the same percentage of their rated power.

Mode B: Asymmetric Load Sharing.
Each generator runs at a preset percentage of its rated power.

Mode C: Asymmetric Diesel-Electric Sharing.

Each generator runs at a preset percentage of its rated power. A certain percentage of the shaft generators power is defined as available for powering  propulsion. The shaft generator can therefore run as a motor increasing the propulsion power of the vessel.

The AUTO-GEN system can be delivered with a control monitor. This can be convenient for systems with many generators but is not necessary for fishing vessels with 2-3 generators.
