FUNCTIONAL DESCRIPTION:

The 8234-299 is a 24 VDC (Low Voltage) 2301A Load Sharing and Speed Control module designed for precision governing of diesel engines, gas engines, or steam turbines. This chassis-mounted controller is an industry standard for managing prime movers in generator set applications. It regulates the engine speed and, when paralleled with other units, ensures that the electrical load is shared proportionally among all generators on the bus.

PROPORTIONAL SPEED CONTROL

The 8234-299 utilizes high-performance PID control logic to maintain a constant engine speed. It receives a frequency signal from a Magnetic Pickup (MPU) and compares it against a setpoint. The internal circuitry then calculates the necessary correction and provides a 0–200 mA signal to the actuator to adjust fuel or steam flow. Field-adjustable potentiometers for Gain, Reset, and Actuator Compensation enable precise tuning to match the engine's specific response characteristics.

LOAD SHARING CAPABILITY

The 8234-299 enables automatic load sharing. By monitoring real power (kW) via Potential Transformer (PT) and Current Transformer (CT) inputs, the module calculates the percentage of load the unit is carrying. When connected to other 2301A units via the load-sharing lines, the Load Sharing & Speed Control module automatically adjusts the speed setpoint to ensure each generator carries its fair share of the total load, preventing instability and load hunting.

INDUSTRIAL DURABILITY AND FLEXIBILITY

The Load Sharing & Speed Control module is designed for continuous operation in harsh environments, including offshore rigs and remote power stations. Its low-voltage DC power requirement makes it ideal for systems powered by standard 24V station batteries. The module supports both Isochronous operation (constant speed) and Droop operation (speed decreases as load increases), providing the flexibility needed for various grid requirements.

FREQUENTLY ASKED QUESTIONS:

What is the Woodward 8234-299?

The 8234-299 is a 2301A series controller used for speed control and automatic load sharing of engine-driven generator sets.

What power supply does this model require?

This is the Low Voltage version, requiring a 24 VDC nominal power source (18–40 VDC range).

Can this module replace a high-voltage 2301A?

While the control functions are identical, you must ensure the power supply in your cabinet matches the 24 VDC requirement of the 8234-299. High-voltage models (like the 9905 series) cannot be directly swapped without power supply modification.

What types of actuators can it drive?

The Load Sharing & Speed Control module provides a 0–200 mA output, making it compatible with the majority of Woodward hydraulic and electric actuators used on industrial engines.
