Application Scenarios

Industrial Power Generation: Coordinate multiple diesel or gas generator sets in manufacturing plants, data centers, and commercial facilities to ensure uninterrupted power supply and optimal load balancing during peak demand or utility outages.

Oil & Gas Operations: Control generator sets on offshore platforms, refineries, and pipeline compressor stations where reliable parallel operation is essential for safety and continuous production.

Marine & Propulsion Systems: Manage shipboard generator sets for cruise ships, cargo vessels, and naval applications, ensuring stable electrical distribution and redundancy during voyage.

Utility & Grid Support: Deploy in distributed generation systems, microgrids, and peaking plants to provide frequency regulation and load sharing in parallel with utility grids or standalone island mode.

System Integration & Solutions

The Woodward 8273-501 integrates seamlessly with Woodward actuators (electric, hydraulic, or pneumatic), speed sensors (magnetic pickups, Hall effect), and communication networks. It works in conjunction with synchronizers, voltage regulators, and protective relays to form a complete generator control solution. The module supports both standalone operation and networked configurations for centralized monitoring via SCADA or plant control systems.

For optimal performance, pair the 8273-501 with Woodward's ProAct or GAP actuators, ensuring precise fuel control and rapid response. The controller's analog and digital I/O allow connection to external devices such as PLCs, HMIs, and remote monitoring systems, enabling real-time diagnostics and performance optimization.

Frequently Asked Questions

Q: Can the 8273-501 control both diesel and gas engines?
A: Yes, the 2301D series is compatible with diesel, natural gas, and dual-fuel engines when paired with appropriate actuators and configured for the specific fuel system.

Q: How many generators can be paralleled with this controller?
A: The 8273-501 supports parallel operation of multiple generator sets (typically 2-16 units) depending on system architecture and load sharing network configuration.

Q: Is this module compatible with older 2301A analog controllers?
A: The 2301D digital series offers enhanced features over the 2301A analog line. While both can coexist in a facility, direct parallel operation between analog and digital controllers requires careful engineering and may need additional interface hardware.

Q: What is the typical lifespan of the 8273-501?
A: With proper installation, maintenance, and operating conditions, Woodward digital controllers typically provide 15-20+ years of reliable service in industrial environments.

Q: Does this unit require special programming or configuration?
A: The 8273-501 comes factory-configured for standard applications. Fine-tuning and custom parameter adjustments can be performed using Woodward's configuration software and service tools, typically handled by trained technicians during commissioning.
