Functional Description

IC3600SFPB1B is a Generator Drive Circuit Board developed by GE Fanuc. Designed for speed control by enabling droop mode operation through a configurable resistor network and allowing acceleration rate reprogramming for smoother startups and load adjustments, making it vital for stable and efficient turbine performance.

Features

This board is designed to provide two primary functions to the Speed Control Card:

Droop Mode Operation Support

Features an integrated resistor network, enabling the system to operate in droop mode. Droop mode is commonly used in turbine control systems to ensure load-sharing between multiple generators operating in parallel.

The resistor network can be configured in two different ways:

• Permanent Connection: If the resistor network is required to be permanently active in the circuit, the system uses the SJA output.
• Switchable Connection: If the operator needs the flexibility to switch the network in and out of the circuit, the system uses the SJB output. In this configuration, the ISOC signal must be set to 1 to activate the resistor network.

This flexibility enables the board to adapt to various system configurations and operating conditions, making it suitable for a range of turbine control strategies.

Acceleration Rate Reprogramming

In addition to droop mode control, also provides a signal that can be used to reprogram the turbine’s acceleration rate.

• This function is especially useful in applications where controlled startup or load adjustment is required. By managing the acceleration rate, operators can reduce mechanical stress, improve system stability, and enhance overall turbine efficiency.

The board uses the FSA input to control this function. If FSA = 0, a fixed bias output is provided through ARA, ensuring a stable and predictable acceleration profile.

FREQUENTLY ASKED QUESTIONS

What is IC3600SFPB1B?
It is a Generator Drive Circuit Board developed by General Electric Fanuc.

What is droop mode, and how does this board support it?
Droop mode allows multiple generators to share load effectively when operating in parallel. The board provides a resistor network that can be permanently connected using SJA output or switched in and out of the circuit via the SJB output with the ISOC signal.

How does the board control turbine acceleration?
It provides a signal for reprogramming the turbine’s acceleration rate. When FSA becomes 0, it outputs a fixed bias through ARA, ensuring smooth and controlled acceleration.
