    General vacon · 5 1. General This application is not kept backwards compatible. See chapter Compatibility issues before you update the application. The Grid Converter application is used to make AC grids with a possibility to operate in parallel with other power sources. The Grid Converter application has 3 different operation modes: Standard AFE mode.

  • Page 8: Micro Grid

    6 · vacon General Micro Grid Micro Grid mode controls the grid voltage and frequency. It functions like an ordinary generator. Micro Grid mode does not control DC Voltage. With the help of voltage droop and frequency droop, more than one Micro Grid and/or Generators can work together.

  • Page 9: Operation Principle: Droop Speed Control Mode

    General vacon · 7 1.3.1 Operation principle: Droop Speed Control Mode When the power demand increases, all generators on the grid allow frequency to droop. This will balance the load between all the generators on the grid. Then the power management system gives all generators a command to increase frequency so that the grid frequency is maintained at its nominal value.

  • Page 10: Shaft Generator

    8 · vacon General Shaft Generator The shaft generator is a system where the generator is connected to the main engine shaft that also runs the main propulsion. The disadvantage is that the main engine must run at nominal speed even if full power to the propeller is not necessary.
