Application Scenarios

Engineered for demanding industrial environments where multiple generator sets operate in parallel configuration. The 2301D excels in marine propulsion systems, offshore drilling platforms, data center backup power installations, hospital emergency generation systems, and industrial cogeneration facilities. Its robust architecture ensures reliable performance in mission-critical applications where power continuity cannot be compromised.

Advanced Control Solutions

The module implements sophisticated droop and isochronous control modes with seamless transition capability. Real-time load distribution algorithms prevent hunting and oscillation between paralleled units while maintaining optimal fuel efficiency. Integrated protection features include overspeed shutdown, underspeed alarm, loss of speed signal detection, and actuator fault diagnostics. The system supports both electronic and mechanical actuator interfaces with auto-calibration routines.

System Integration & Configuration

Field-programmable parameters enable customization for specific engine characteristics and application requirements. The configuration interface supports gain scheduling, PID tuning, ramp rate adjustment, and droop slope modification. Multi-unit synchronization maintains phase alignment within ±5 electrical degrees during paralleling operations. The controller interfaces seamlessly with existing SCADA systems through industry-standard communication protocols.
