Core Function

ACLE application control layer assembly for EX2100 excitation system. IS215ACLEH1A is the finished assembly, while IS200ACLEH1AAA is the underlying base circuit board. It undertakes generator excitation outer‑loop algorithm calculation, executes AVR, PSS and excitation limit protection logic. It communicates with DSPX inner‑loop processing board via VME backplane bus, and realizes data interaction with HMI and plant DCS through Ethernet and serial interfaces. It supports simplex and TMR triple‑modular redundant excitation configuration, stabilizes generator terminal voltage and suppresses power grid oscillation, which is the core control unit of EX2100 excitation system.

Product Details

IS215ACLEH1A assembly adopts IS200ACLEH1AAA as the base board, it belongs to ACLE series outer‑loop control hardware for GE EX2100 excitation control system.

The real‑time processor runs excitation outer‑loop application logic, calculates the excitation setting value and sends commands to DSPX inner‑loop board. It realizes generator voltage closed‑loop adjustment, power system stabilizer function, over‑excitation and under‑excitation limit protection. Dual Ethernet provides redundant network channel for man‑machine interface and DCS system; COM serial ports support local debugging and third‑party device access. CompactFlash stores system firmware and user configuration parameters to ensure data retention after power‑off. Front‑panel LED indicators clearly display module running status, network link and fault information for convenient on‑site inspection and troubleshooting. Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to harsh environment of power‑plant excitation cabinet. Widely deployed in simplex and TMR redundant generator excitation cabinets of combined‑cycle power plant.

It belongs to critical outer‑loop control spare‑part for EX2100 excitation system, widely used in overhaul and renovation projects of power generation units.

It is important spare hardware for excitation outer‑loop logic debugging and defective IS215ACLEH1A / IS200ACLEH1AAA module replacement.
