UNITROL 1020 UNS0119A-Z,V1 3BHE030579R0003 | ABB Automatic voltage regulator

ABB UNITROL 1020 UNS0119A-Z, V1 3BHE030579R0003 Automatic Voltage Regulator

· By adopting advanced control algorithms and technologies, the terminal voltage of the generator can be adjusted and controlled with high precision, ensuring that 

the output voltage of the generator can remain stable under different load conditions, meeting the strict requirements of the power system for voltage stability.

· When voltage fluctuations or load changes occur in the power system, it can quickly respond and adjust the excitation current of the generator, thereby quickly stabilizing 

the terminal voltage of the generator. The response time is generally in milliseconds, which can effectively prevent voltage quality problems such as voltage sag and sag, 

and ensure the stable operation of the power system.

· Support multiple control modes, such as manual control, automatic control, constant reactive power control, constant power factor control, etc. Users can flexibly choose 

and switch control modes according to their actual power system operation needs and generator operating conditions to meet different operation and control requirements.

· The design focuses on reliability and stability, using high-quality electronic components and strict production processes. It has complete protection and diagnostic functions

 internally, which can operate stably for a long time in harsh industrial environments, reduce downtime and maintenance costs caused by equipment failures, and improve 

the reliability and availability of the power system.

· Having multiple communication interfaces and protocol support, such as Profibus Modbus、 Industrial Ethernet and other technologies facilitate data exchange and 

integration with other devices and systems, such as connecting with monitoring systems and relay protection systems in power plants, enabling remote monitoring, 

parameter setting, and fault diagnosis of generator excitation systems, thereby improving the automation management level of power systems.
