Product Overview

Brand and Series: Woodward EASYGEN series, specifically designed for generator set control, belonging to the Marine model, suitable for harsh environments such as ships and offshore platforms.

Model Explanation:

EASYGEN-3500-5/P2: Core controller model. “P2” indicates extended configuration (such as remote panel connection, enhanced communication capabilities), supporting parallel control of multiple generator sets.

Marine: Marine-certified model, featuring corrosion resistance, shock resistance, and moisture resistance, conforming to marine standards (such as ABS, Lloyd’s Register).

　　Core Functions and Technical Parameters

Speed ​​Regulation and Control:

Precisely adjusts generator speed and frequency, supports load balancing and automatic synchronization (phase matching, frequency sliding control), ensuring stable operation when multiple units are connected in parallel.

Supports proportional load sharing (iso-time/decreasing mode) for up to 32 generator units, adapting to different load requirements.

Automation and Integration:

Integrates LogicsManager™ programmable logic, reducing the need for additional PLCs, and can be seamlessly integrated with SCADA or PLC systems.

Supports CAN network communication (SAE-J1939 protocol), Modbus RTU, and connects to remote panels (such as RP-3500) via CANopen protocol, with a distance of up to 250 meters.

Protection and Safety:

Full-function protection for the engine and generator (programmable settings), supporting Automatic Mains Fault Detection (AMF), emergency operation, and circuit breaker control (GCB/MCB).

Compliant with marine certifications (CE, UL/cUL, CSA, BDEW, ABS, etc.), ensuring reliability in marine environments.

Environmental Adaptability:

Operating voltage 24V, output frequency 60kHz, adaptable to normal temperatures to extreme environments (such as high temperature, high humidity, and salt spray corrosion).

Generator Set Control: Enables generator set start/stop, speed/frequency regulation, load balancing, and synchronization.

Remote Monitoring and Data Management: Enables remote monitoring, data logging, and SCADA system integration via Modbus RTU or CANopen protocols, supporting PC-based configuration tools (such as Woodward ToolKit).

Parallel Operation and Synchronization: Supports proportional load sharing (iso-time or droop mode) for up to 32 generator sets, ensuring load balancing and synchronization during parallel operation of multiple units.

　　Application Scenarios

Marine and Marine Engineering: Marine generator set control to ensure stable power supply during navigation, suitable for cargo ships, cruise ships, offshore platforms, etc.

Industry and Emergency: Emergency backup power for data centers, hospitals, and industrial facilities; distributed generation (DG), microgrids, and combined heat and power (CHP) systems.

Special Scenarios: Oil and gas exploration, power supply in remote areas, and power management for leased/mobile equipment.

　　Configuration and Expansion

Remote Monitoring: Configurable via the Woodward ToolKit service, supporting remote panel connection for real-time status monitoring, parameter adjustment, and fault diagnosis.

Expansion Capabilities: Supports asynchronous generator control and input/output expansion modules to adapt to different load requirements (e.g., basic load, asymmetrical load).

Compatibility: Communicates with engine ECUs via CAN network, supports multiple proprietary protocols, and is compatible with mainstream SCADA systems.

　　Certifications and Standards

Complies with International Maritime Organization (IMO) and International Electrotechnical Commission (IEC) standards, and is certified by classification societies such as ABS and Lloyd’s Register, ensuring safety and compliance in marine environments.

Summary: This product is a high-performance speed controller launched by Woodward for industrial generator set control, especially suitable for marine, island power supply, and high-reliability scenarios. Its core advantages lie in multi-unit parallel control, automated protection functions, and remote monitoring capabilities. It complies with international safety and maritime standards and is a key component for the automation and intelligent upgrading of generator sets.
