The controller’s integrated features can also optimize fuel usage, making it an economical choice for multi-genset applications.
Detailed Product Description
The Woodward 8440-1884 (easYgen-2500-5) is a compact and highly versatile genset controller. Its robust design and rich feature set make it a popular choice for a wide range of power generation applications, from emergency standby to complex islanded systems.
- Integrated Display and User Interface: The built-in graphical LCD and soft keys allow for easy on-site configuration, monitoring, and control without the need for an external computer. The multi-level password protection ensures that changes are only made by authorized personnel.
- Flexible Control and Protection: The controller provides comprehensive protection for the engine, generator, and mains. It includes configurable set points for trip levels, frequency, speed, voltage, and power factor, allowing it to be tailored to specific application requirements.
- Load Management and Efficiency: A key feature is its ability to perform load-dependent start/stop functions. In a system with multiple gensets, it can automatically bring units online as the load increases and shut them down when the load drops, ensuring that only the necessary generators are running to meet demand. This is particularly useful for optimizing fuel efficiency.
- Wide Application Range: The controller is suitable for a variety of applications, including:
- Emergency standby for hospitals, data centers, and industrial facilities.
- Distributed Generation (DG) for utility peak demand response.
- Islanded prime-power for marine, remote villages, and oil & gas exploration.
- Connectivity: The support for multiple communication protocols allows the 8440-1884 to integrate seamlessly into a larger plant-wide control system, enabling remote monitoring and control via SCADA or PLC systems.
