The ABB Unitrol 1020 3BHE030579R0007 is an automatic voltage regulator (AVR) belonging to the ABB Unitrol 1000 family.

It’s specifically designed for small and medium-sized synchronous generators and industrial machines.

• Automatic Voltage Control: It maintains consistent voltage output by adjusting the excitation current supplied to the generator’s field windings. This is achieved through a built-in Proportional-Integral-Derivative (PID) controller.
• Power Factor and Reactive Power Management: The Unitrol 1020 can also regulate the power factor and reactive power output of the generator, improving overall system stability. It also utilizes a PID control algorithm for this function.
• Advanced Features:
  • Dual Channel Support: Enables controlling two generators simultaneously.
  • Load Sharing: Ensures balanced distribution of load among multiple generators operating in parallel.
  • Rotating Diode Monitoring: Monitors the health of the rotating diodes within the generator.
  • Automatic Synchronization: Simplifies the process of synchronizing the generator with the electrical grid.
  • Communication Options: Integrates with various communication protocols for remote monitoring and control.
