Introduction
1.Main Functions
- Generator automatic voltage regulation (AVR): Collect generator PT voltage signals in real‑time, control excitation output in closed‑loop to stabilize generator terminal voltage and guarantee power qualityABB Group.
- Multi‑mode control switching: Support multiple regulation modes including voltage regulation, field current regulation (FCR), power factor (PF) and reactive power (VAR), suitable for stand‑alone and parallel‑operation conditions of multiple generatorseero.
- Excitation limitation & protection: Built‑in over‑excitation, under‑excitation and stator current limiters; soft field‑boost and fault ride‑through (FRT) detection to avoid excitation‑side failures of generatorsABB Group.
- Voltage matching for synchronisation: Perform voltage matching before grid connection to provide control conditions for generator synchronizing paralleling.
- Signal acquisition & I/O processing: Acquire PT/CT voltage‑current signals and digital status signals; equipped with digital / analog I/O to connect field switches, sensors and power units.
- Commissioning & status monitoring: Parameter setting and PID tuning via CMT1000 tool; on‑board status LED indicators for operation, alarm and fault feedbackABB Group.
- Basic communication: Support USB commissioning interface for parameter upload/download and fault reading. The ECO is the economy‑base software configuration covering core excitation control functionsABB.

2.Main Applications
This unit is the economy‑type digital excitation regulator of UNITROL 1000 series, designed for medium‑small synchronous generators with max. 5A DC excitation output, mainly applied for indirect excitation systems.
‑ Applied for excitation control of synchronous generators in hydropower, thermal power, gas turbine units, industrial captive power plants and distributed energy systems.
‑ Realize closed‑loop control of generator voltage, reactive power and power factor, supporting stand‑alone operation or parallel grid‑connection of multiple units.
‑ The ECO variant targets cost‑sensitive projects with full core control logics for excitation systems. Widely used in industrial captive power stations, small‑medium hydropower plants and marine generator sets to ensure safe and stable power generation of generatorseero.
