FWL/S Digital Excitation System for PMG Generator
Introduction
FWL/S series excitation system is made up of automatic excitation regulating device, manual excitation regulating device, static rectifier bridge, non-linear de-excitation and over voltage protection device etc.
Functions
- AVR uses 32-bit DSP as the core, and is made up of double channel excitation regulator and module of thyristors. Its structure can employ master-slave or parallel manner.
- High-speed and high-efficient non-linear de-excitation.
- Have the function of excitation time compensation and rotor voltage soft feedback, and meet the special requirements of high starting response excitation system.
