Function and Role

Signal Input and Conversion: The KS D211 B101 input coupling unit is used to receive various input signals in the excitation system, such as voltage and current signals from the generator and relevant control signals from the regulator. It converts these signals into forms that can be recognized and processed by the subsequent control unit, playing a role in signal conditioning and matching.

Electrical Isolation: It provides electrical isolation between the input signals and the internal circuits of the excitation controller, preventing interference and potential damage from external electrical signals to the controller. This helps improve the stability and reliability of the excitation system, especially in harsh electromagnetic environments.

Data Pre - processing: Before the input signals are sent to the main controller for processing, the KS D211 B101 can perform some simple data pre - processing operations, such as filtering, amplification, and digital conversion. This can reduce the processing burden of the main controller and improve the overall efficiency and response speed of the excitation system.

Application Scenarios

UNITROL 6000 Series Excitation Systems: It is an important component of the UNITROL 6000 series of static excitation systems, which are widely used in power generation units such as hydropower plants, thermal power plants, and nuclear power plants. These excitation systems are suitable for power supplies with frequencies of 50 Hz, 60 Hz, or 16 2/3 Hz, and field currents ranging from 1000 A DC to over 10,000 A DC.

Automatic Voltage Regulation Systems: It is also applicable to automatic voltage regulating systems (AVR) for exciter machines with special functions, covering supply frequencies from 16 2/3 Hz to 400 Hz.
