A novel digital Automatic Voltage Regulator for synchronous generator

In this paper, a Digital Signal Processor (DSP) based Automatic Voltage Regulator (AVR) for synchronous generator is proposed. Analysis and development of the proposed regulator is done by both computer simulations and DSP implementation. Steady state and dynamic control performance of the regulator are investigated on different working conditions (such as voltage establishment, load connection and disconnection). A hardware platform of the AVR which uses DSP TMS320F2812 as the microprocessor is set up. Several novel methods have also been adopted in the configuration of the hardware for a better dynamic performance. Experiment results show good consistency to the simulation results.
