Product Introduction
The ABB UNITROL 1010 is an integrated AVR and excitation power unit built for brushless synchronous generators and synchronous motors. It samples generator VT and CT signals and adjusts IGBT field output to hold steady voltage under changing load.
It includes protective limiters and reactive power sharing logic for parallel generator operation. It supports grid code compliance and fault ride-through behavior, and it can be configured for islanded or grid-tied operation.

Application Scenarios & Field Experience
Many older analog excitation regulators drift or lack modern protection functions. Replacing them with a digital UNITROL 1010 removes tuning drift while fitting the same footprint in many existing cubicles. Mismatched regulator response can trigger grid instability or generator trips.
- Hydroelectric plant: Small hydro generator excitation for grid-parallel and island operation.
- Cogeneration facility: Gas engine synchronous generator voltage and VAR control.
- Marine vessel: Auxiliary generator excitation for shipboard power networks.
- Industrial standby power plant: Diesel-driven synchronous generator for backup load.
In my experience, a small hydro site replaced a failing analog regulator with a UNITROL 1010. The engineering team imported the target voltage and droop settings through CMT1000. The unit synchronized without oscillation, and the site eliminated the weekly voltage drift corrections they had performed for years.
Standard Operating Procedure (SOP) for Quality Control
- Visual & Origin Inspection: Check OEM labels, serial number, terminal block condition, and anti-counterfeit markers against OEM documentation.
- Live Rig Testing: Apply rated auxiliary supply, inject VT/CT simulated signals, run self-test and verify regulation response.
- Firmware Verification: Read and log firmware revision; match revision to the site’s planned grid code and feature set.
- Communication & I/O Test: Verify Modbus TCP read/write, digital input status, relay alarm outputs.
- ESD-Safe Packaging: Seal in static-dissipative bag, add foam cushion, rigid outer carton, and ESD warning labels before shipment.
Frequently Asked Questions
Q1: Is the UNITROL 1010 interchangeable with UNITROL 1020? A: They share the same software platform, but UNITROL 1020 supports higher continuous excitation current. Do not swap them unless the generator field current stays under 10 A. Confirm the OEM rating sheet before substitution.
Q2: What warranty coverage do you provide for this UNITROL 1010 unit? A: We offer 12 months warranty. Warranty covers factory-tested hardware defects; it does not cover surge damage, miswiring, field overcurrent, or improper parameter setup.
Q3: Can this item ship immediately, or do we need to confirm stock lead time? A: Stock status updates on our website. If marked in stock, shipment can start within 1–3 business days. If inventory is depleted, we will quote confirmed lead time before order lock.
Q4: What happens if firmware revision does not match the site’s grid code requirements? A: Older firmware builds may lack required fault ride-through or PSS logic. Do not commission the unit without checking revision notes against the local grid code. We can source the specified revision if available.
Q5: Can I hot-swap the UNITROL 1010 while the generator stays online? A: Hot-swap is not supported for this integrated excitation regulator. You must transfer to manual field control or shut the generator down before removal. Removing power during active regulation will cause voltage collapse and a generator trip.
