Exciter-10 (EX-10) module is a power electronics component designed to provide excitation current to the generator that is controlled by the Active Voltage Regulator (AVR) feature in the KEA 350 (RP) genset controls.
The active voltage regulation concept intends to substitute a traditional voltage regulation configuration by simplifying the overall topology. The KEA 350 (RP) internal controller regulates generator output voltage by sending a pulse width modulation (PWM) signal to the excitation module. The excitation module controls generator excitation and therefore generator output voltage. This topology eliminates the redundant voltage and current sensing from a traditional voltage regulator and also makes a feedforward control architecture at AVR level simplifying the cascaded PID control topology. For power input, EX-10 interfaces with any of the following excitation systems:
- Self/Shunt Excitation
- Auxiliary winding/AREP Excitation and
- Permanent Magnet (PMG) Excitation
systems to make it a standard yet versatile solution.
