GE IS200EDSLH2A EX2100e, REG DUAL SEL

الوصف

The GE part number IS200EDSLH2A is an EX2100e Regulator Dual Selector board. It is a crucial Printed Circuit Board (PCB) in GE’s Mark VIe Excitation Control System. Its primary function is to provide the logic and switching required to seamlessly transfer control between the two redundant regulators in a dual-regulator configuration. ⚡

Function and Key Features

In a dual-regulator system, there are two identical control modules (often designated “Regulator A” and “Regulator B”) operating in parallel to provide a high level of reliability and redundancy. The EDSL board manages this redundancy.

• Dual Regulator Control: The EDSL board constantly monitors the status and health of both the primary and backup regulators. It contains the logic to determine which regulator is “active” or in control of the generator’s field excitation.
• Seamless Transfer: A key feature of this board is its ability to perform a bumpless transfer between the two regulators. If the active regulator fails or is taken offline for maintenance, the EDSL board can instantly switch control to the standby regulator without any interruption or disturbance to the generator’s output.
• Selector Logic: The board contains the circuitry and logic to perform the “selection” of the active regulator based on pre-programmed rules and system health diagnostics.
• System Integration: The EDSL board works in conjunction with the main control cards (like DSPX) and other I/O boards to form the complete EX2100e system.
• Robust Design: Like all GE industrial control components, it is built to withstand the harsh conditions of a power plant.

Applications

The IS200EDSLH2A is a key component in power generation facilities that have upgraded to the Mark VIe Excitation Control System. It is used for:

• High-Reliability Applications: It is essential for applications where an uninterrupted power supply is critical, as it ensures that a failure in the control system will not cause a generator trip.
• Maintenance: It allows for online maintenance and troubleshooting of a regulator, as a technician can safely switch to the backup regulator and then service the primary unit without having to shut down the generator.
