IS215ACLEH1A IS200ACLEH1AAA

IS215ACLEH1A, with base board IS200ACLEH1AAA, is the main controller for GE EX2100 excitation system. It performs AVR regulation, excitation control, logic calculation and redundant communication, applied to generator excitation control.

Description

1. Product Overview

Model Relationship

  • IS215ACLEH1A: Fully assembled Application Control Layer (ACLE) main controller module, the core control unit of GE EX2100 Excitation Control System.

  • IS200ACLEH1AAA: Core Carrier Board, the base PCB motherboard of IS215ACLEH1A, equipped with a PC/104-Plus processor daughterboard to form the complete ACLE module.

Brand & Series

  • Brand: General Electric (GE)

  • System: EX2100 Excitation Control System, for excitation regulation of gas/steam/hydro generators and synchronous motor control, compatible with simplex/redundant (hot standby/TMR) architectures.

Core Purpose

As the main control core of the EX2100 system, it executes excitation control algorithms, monitors parameters, diagnoses faults, manages communications, handles alarms, and connects with controllers, HMIs, and field devices via dual Ethernet/serial ports to achieve precise closed-loop control of generator excitation current/voltage and ensure stable grid connection and operation.

Core Functions

  1. Runs closed-loop excitation control algorithms (PID, AVR, over/under excitation limit, V/F limit, etc.) for real-time excitation output regulation.

  2. Dual 10BaseT Ethernet and dual RS-232 serial ports for system communication, data exchange, remote monitoring and configuration.

  3. Non-volatile CompactFlash stores firmware/configurations (no battery backup required), supports online program loading and parameter modification.

  4. Real-time status monitoring, fault diagnosis, alarm output; configurable, debuggable and diagnosable via GE Toolbox software.

  5. Compatible with EX2100 simplex/redundant backplanes (IS200ESBP/EBKP/ERBP/ERRB), supports hot standby redundancy and bumpless transfer.
