The brushless synchronous generator (SG) excitation system consists of a main exciter, permanent magnet (PMG) consequent rotor poles type, and an automatic voltage regulator (AVR). Both exciter machines have been properly designed analysed. performances are obtained by time stepping finite-element method (FEM) coupled with the external electrical circuit. An experimental machine is built measur...

In our work, we have been interested in conducting technological research on the use of photovoltaic energy for lighting. fact, produced a stand-alone system with automatic search maximum power point, consisting module, solar regulator, storage battery and digital control by microcontroller. The field is connected to input regulator its output. When voltage lower than regulation voltage, contro...

This article presentes a PID controller for two area power system equipped with both automatic generation control and automatic voltage regulator loops. The research has been done to control two area power systems with PSO optimized self-tuning PID controller. The comparison between different controllers and the suggested PSO based controller illustrates that the proposed controller can generat...

Generators typically regulate terminal voltage via automatic voltage regulator and exciter equipment. The desired high side (transmission side) voltage schedule is usually maintained by the power plant operator or by slow SCADA-type process control computers. Power system dynamic performance, however, can be improved by faster regulation of the transmission voltage. Contrasted to generators, st...

Automatic voltage regulator (AVR) represents the basic loop in power systems. The central part of this is regulator, which has parameters that define speed regulation, quality responses, and system stability. Furthermore, it an impact on excitation change value, especially during transients. In paper, unlike literature approaches, experimental verifications current value are presented. A novel ...

The paper describes an optimal parameter selection method of automatic voltage regulator (AVR) for a large power plant in order to improve power system stability. The AVR is generally used to control the output voltage of the generator by regulating the excitation voltage in a generator rotor. In order to improve transient stability in power system, the paper proposes the method to select optim...
