Woodward 9905-096 AGLC Automatic Generator Loading Control
Product Brief Description
Woodward 9905-096 is the AGLC (Automatic Generator Loading Control) unit. It is designed to work with Woodward speed controllers such as the 2301A series. Its core function is to control the generator loading rate smoothly after synchronizing to the grid, preventing rapid load change shock to prime movers and grid. It is widely used for steam turbine, gas turbine and diesel generator grid-parallel systems.
Features
- Smooth ramp load control after generator synchronization, adjustable loading ramp rate
- Match with Woodward 2301A speed / load sharing controller, receive contact synchronize signal
- Prevent step loading to avoid prime mover stall, grid frequency fluctuation and reverse power risk
- Built-in status indication: sync ready, loading in progress, load limit alarm
- Configurable maximum load limit and ramp time by internal potentiometer
- Auxiliary power 24VDC, panel mount, simple dry contact and analog signal wiring
- Load hold function, can pause loading when abnormal condition occurs
Application Scenarios
- Power plant steam turbine and gas turbine generator grid connection control
- Industrial self-use power station, oil & gas genset parallel system
- Marine power station generator grid synchronization and loading control
- Retrofit project for old 2301A control system
- Generator slow loading protection spare replacement
FAQ
Q: What is AGLC?
A: AGLC stands for Automatic Generator Loading Control, which controls the ramp-up speed of active power after breaker closure.
Q: What controller does 9905-096 cooperate with?
A: Mainly paired with Woodward 2301A speed and load sharing controller, it cannot work independently.
Q: What is the difference between 9905-096 and synchronizer?
A: Synchronizer completes voltage, frequency, phase matching and gives closing signal; AGLC 9905-096 controls the slow loading after the breaker is closed.
Q: Is this unit discontinued?
A: It is a legacy classic accessory of 2301A system, no longer new production. Supplied by surplus stock and tested refurbished units for maintenance.
Q: What common failures occur?
A: Potentiometer drift, output circuit failure, no ramp loading action, load cannot be maintained after synchronization.
