C6200 FLEXGEN SERIES

Generator Control

Description

FlexGen controllers are intended for paralleling of generators
with each other or with the grid. One FlexGen controller is
installed for each generator in the installation and handles all
electrical control.

There are two versions available, Basic and Advanced.

Both versions include basic functions such as autosynchronizing,
frequency control, active load sharing, dead bus monitoring and
reverse power protection. In addition the FlexGen Advanced
contains reactive load sharing, voltage matching, power factor
control, grid-parallel operation control, and protection against
excitation loss, RoCoF (df/dt), and vector shift. FlexGen Advanced
also contains over-current and short-circuit protection and power
management features like preferential load trip, load depending
start/stop and large consumer control.

Both models include MODBUS RTU interface enabling integration
with equipment from other manufacturers, for example, control
and monitoring from PC with a graphic SCADA interface. FlexGen
is type-approved by major marine classification societies and can
be used for marine power management systems.

C6500 FlexGen UI User Interface Module

Provides indication of measurements, alarms,
alarm log and configuration of the generator
module.

The user interface is designed for mounting

in the switch panel door. It furnishes a large
back-lit display showing all electrical measurements and
control parameters.
