Description

GE EX2100E – Digital Excitation Control System

Product Overview

EX2100E is a fully digital static excitation controller for large synchronous generators. It automatically adjusts rotor excitation current to stabilize generator terminal voltage and control reactive power output during grid load variations. This high‑reliability system improves transient stability, supports grid‑code compliance and protects generators from abnormal operating conditions in power plants.
