Genset control KEA 3X0 ensures decentralized power supply in emergency power, CHP and prime power applications

Emergency power applications

In case of power failure KEA 3X0 genset control switches over to emergency power supply of safety-related consumers. With its comprehensive scope of functions the robust KEA 3X0 ensures the reliable plant operation of conventional and complex emergency power applications. The state-of-the-art successor of KEA 2XX series supports all current standard requirements for emergency power applications.

Integrate your PV system!

Rising fuel costs are putting the focus on hybrid systems that combine conventional emergency power systems with regenerative energy generators, such as photovoltaic systems. All genset controls of the Kuhse KEA 3X0 series are already "PV-ready" with the current firmware 2.12 and enable a future-proof combination of a emergency genset and a photovoltaic system. Genset controls with an older firmware can be easily updated to the PV-ready compliant firmware 2.12.

In the event of a mains failure, this offers several advantages:

  • Savings in energy costs due to the parallel operation of the standby genset and the PV system
  • Reduction of fuel costs
  • Use of one control system for the standby genset and PV system
  • Reduction of CO2 emissions

The control of the PV plant by the KEA 3X0 can be done via BDEW contacts, an analog signal or via the Modbus interface.

CHP and prime power applications

With the genset controls of KEA 3X0 series standards are raised in genset paralleling control and power management system. Operated in island oder mains parallel operation mode KEA 3X0 enables load sharing of up to 32 generators with a single utility feed. The control combines complete engine-generator control and protection with advanced, peer-to-peer paralleling functionality and innovative features in a robust, attractive, user-friendly and all-in-one package. Its integrated programmable logic functionalities provide outstanding application flexibility and can often eliminate the need of an additional PLC control, yet can easily integrate with SCADA or PLC-based control systems where desired.

High user-friendliness

An essential contribution to security of supply makes the user-friendliness of control unit. For decades and even today its simple operation concept convinces plant operators.

Besides controlling of new plants KEA can be used for retrofit concepts of existing plants. KEA is available as single device for front and back panel mounting as well as function tested complete switchgear including all control components.
