ABB PPD517A3011 Excitation central controller

High precision control: provides accurate excitation current control. Ensure the stability and quality of generator output voltage. Performance is maintained even when loads change or the grid fluctuates.
Dynamic response: Fast dynamic response capability. The ability to quickly adjust the excitation current in response to transient changes in the grid. Such as short-circuit fault recovery or load sudden change.
Intelligent adjustment: with advanced control algorithms, such as PID (proportional integral differential) control. Intelligent adjustment of excitation current. Optimize the operating efficiency of the generator.
Communication capability: Supports a variety of communication protocols, such as Modbus, Ethernet, etc. It can exchange data with host computer or power station automation system. Realize remote monitoring and control.
Fault diagnosis: Provides fault detection and diagnosis functions. Can monitor the excitation system status in real time. Identify potential problems in a timely manner. Reduce unplanned downtime.
