Functional Description

IS200EDFFH2A is a DC fanned feedback board developed by GE. It is a part of EX2100e excitation system. This model employs a dual system. A fiber-optic link is required to provide voltage isolation between the EAUX and EDFF boards. The EDFF model is divided into three groups, each with its own system; as an H2 group model, this unit operates as a dual system.

Features

  • The EDFF board has eight selector settings that are used to scale bridge voltages depending on the bridge application.
  • It is capable of measuring field currents and does so via a shunt within the dc field circuit.
  • The fiber-optic link connecting the EUAX and EDFF boards provides voltage isolation between the two boards and also aids in high-noise immunity. The EDFF model consists of two V-F (voltage-to-frequency) converter circuits that are used for field current and field voltage feedback and can support up to three redundant control sections.

Dual Control (Power Bridge Warm Backup)

  • Warm backup (WBU) configuration of the EX2100e Regulator system includes dual exciter control I/O and protection. M1 (Master One) and M2 (Master Two) are the control's two IGBT bridges that can accept separate or shared ac input power.
  • Through the transfer module, the control configuration can also share a common dc output circuit to the exciter field. M1 and M2 are separate controls that each have automatic and manual regulator functions. Bridge firing can be controlled by either M1 or M2, as determined by the operator.
  • M1 controls bridge #1 in the WBU configuration, and M2 controls bridge #2. Two independent Universal Controller Stand-alone Board Version B (UCSB) controllers with separate PCMs and an output selector module (SCM or TCM) provide the dc output current for the exciter field to process application software (or SCT control winding).
