Generator Controllers synchronizing and load sharing

Open the catalog to page 1

SELCO FlexGen The SELCO FlexGen product line is a range of integrated generator controllers. FlexGen is the second generation of the C6200 GenController and is built on the same state of the art technology platform. As well it is a further development of the SELCO SIGMA system, including many unique power management features. FlexGen is complementing to the various solutions for synchronizing and load sharing available from the SELCO T-Line range. FlexGen provides a broad variety of options with regard to user configuration and interfacing to machinery and peripheral control. The extended...

FlexGen Features FlexGen controllers are intended for paralleling of generators with each other or with the main power grid. The controllers can be set for local frequency and voltage control, or work with an external frequency and load set point from the main grid or an isochronous power source, such as a wind turbine or a solar panel transformer. One FlexGen controller is installed for each generator in the installation and handles all electrical control. The controllers include inputs for changing between manual and automatic operation. The 3 FlexGen versions all include the same basic...

Voltage matching and Frequency control connect at the same time following a black-out. FlexGen Compact and FlexGen Advanced can control both the voltage and the speed/frequency of the generator. can be activated/deactivated from the programmable inputs, enabling seamless mode change over between island mode and grid-parallel mode with almost no additional wiring. Active load sharing (kW) Generators running in parallel operation. Through connection of dedicated load sharing lines all FlexGen controllers can handle paralleling of a generator to other generators controlled by FlexGen, C6200,...

Configuration and installation FlexGen can be configured from PC using the SELCO WinConfig software. The WinConfig software provides a user friendly screen lay-out. Easy access to all parameters is available from a logical flat menu structure. Configuration is carried out in real time. Subsequently parameters are immediately updated when changes are made. Complete configurations can be saved and uploaded in new controller units in a few steps, thus making it a flexible tool both in the design work when trying out different ways of operating the system, and in the actual installation work....

Applications From the simple one generator power back-up installation to the more complex grid-parallel or island mode operation FlexGen is always ensuring a cost effective power control solution due to the possible choice between the 3 levels of functionality included in the different FlexGen versions. FlexGen is well suitable for use in: • ack-up power systems where down time is critical for safety or economic B reasons, like in hospitals, airports, cable ways, energy generation and distribution, processing of food or pharmaceutical products, storage of food, chemicals and pharmaceutical...
