Country of Origin
This engine control system is designed and manufactured by Woodward, Inc. in the USA, a global leader in energy control and optimization solutions.
Application Fields
The 8446-1019 is primarily used in distributed power applications where automation is key:
- Automatic Mains Failure (AMF): Automatically starting a generator and transferring load when the utility power fails.
- Peak Shaving: Managing generators to run alongside the utility during periods of high electricity costs.
- Base Loading: Maintaining a constant generator power output against a utility bus.
- Islanded Operation: Governing the voltage and frequency of isolated grids.
- Parallel Operation: Synchronizing and load-sharing between multiple generator sets.
Product Usage Instructions
- Mounting: Install the unit in a panel cutout, typically on the generator set’s control cabinet door. Ensure the gasket is properly seated for moisture protection.
- Wiring: Connect the 3-phase generator and bus voltage sensing leads. Warning: Use appropriate fusing on sensing lines.
- Speed Control: Connect the ±3 V DC or 500 Hz PWM output to the engine’s electronic governor.
- Voltage Control: Connect the bias output to the Automatic Voltage Regulator (AVR) for reactive load sharing and synchronization.
- Configuration: Use the front-panel keys or the Woodward Watch Window software to set parameters for “Rated Speed,” “Voltage Setpoint,” and “Sync-Check Window.”
Product Technical Description
The EGCP-2 8446-1019 acts as the master coordinator for a generator set. It replaces a variety of standalone components including the synchronizer, the load sensor, and the protective relays. Technically, it uses a high-speed processor to perform “Real Power” (kW) and “Reactive Power” (kVAR) calculations. During synchronization, the unit monitors the phase angle, frequency, and voltage difference between the generator and the bus, automatically adjusting the engine speed and generator excitation until the conditions are met for a “bumpless” closure of the circuit breaker. Its integrated protection suite monitors for faults like reverse power, overcurrent, and under-frequency, ensuring the generator is tripped before damage occurs.
Q&A (Common Questions)
Q: Can this unit handle 400Hz systems? A: No, the 8446-1019 is designed for standard 50Hz and 60Hz utility and industrial power systems.
Q: Does it support remote monitoring? A: Yes, via the RS-485 port and Modbus RTU protocol, it can be interfaced with HMI/SCADA systems or PLC-based master controllers.
Q: What is the difference between the 8446-1019 and other EGCP-2 models? A: Different part numbers in the EGCP-2 series usually denote variations in software features (e.g., Engine Management vs. Cogeneration) or specific hardware revisions. The 1019 is a standard feature-set model.
Q: Is it possible to use this with a mechanical governor? A: It requires an electronic interface. If your engine has a mechanical governor, you must add a Woodward actuator and an electronic speed control module to interface with the EGCP-2.
