The ABB 3BHE016011R0006 UNS0118A-Z is a sophisticated Voltage Regulator (AVR) that is part of ABB's UNITROL 1000 series. This AVR is designed to provide reliable voltage regulation for industrial generators, particularly small to medium-sized synchronous generators.

It ensures consistent and stable voltage output, improving the reliability and performance of the power generation system.

Excitation Regulation: Uses PI control to manage the excitation current and maintain stable voltage output.

3BHE016011R0006 UNS0118A-Z  High precision in maintaining the output voltage, reducing voltage fluctuations during system changes.

3BHE016011R0006 UNS0118A-Z Up to 20 ADC continuous current output for reliable operation in power systems with varying loads.

Overcurrent Protection:  limits excessive current to protect the equipment.

Overvoltage and Undervoltage Protections: Ensures that voltage remains within safe operating limits.

Rotating Diode Monitoring (RDM): Monitors the condition of the exciter's rotating diodes to prevent failures.

PID Controller: The AVR uses PID control algorithms to adjust voltage and react to system conditions.

3BHE016011R0006 UNS0118A-Z Precision voltage regulation to maintain output stability within ±1% of set point.

3BHE016011R0006 UNS0118A-Z input voltages ：80 to 280 V AC 

Supply Voltage: 24V DC for the regulator itself, providing low-voltage operation.

Power Plants: Ensures voltage stability in power generation systems.

Substations: Provides voltage control to maintain smooth grid operations.

The AVR facilitates automatic synchronization of multiple generators, ensuring smooth operation when generators are running in parallel.

Pre-synchronization voltage matching ensures that voltages are synchronized before connecting generators, reducing the risk of damage.
