Automatic Voltage Regulator with Series Compensation
International Journal of Engineering Trends and Technology, 2015An Automatic voltage regulator (AVR) based series compensation is described in this paper. An AC chopper is used here for producing the compensation voltage. The AC chopper is based on pulse width modulation technique (PWM).The switching pattern of AC chopper will reduce the commutation problems. The direct AC-AC conversion present here will reduce the

A self-tuning automatic voltage regulator
Electric Power Systems Research, 1979Abstract A self-tuning automatic voltage regulator (AVR) for a synchronous generator is presented. The regulator proposed improves the system stability; it is simple and can handle stochastic load changes. The algorithm for the proposed AVR combines a least-squares estimator with a minimum variance control strategy computed from an estimated model ...

Laboratory implementation of Automatic Voltage Regulator
2016 Biennial International Conference on Power and Energy Systems: Towards Sustainable Energy (PESTSE), 2016The terminal voltage of an alternator delivering power to an isolated load will vary depending on power and power factor of the load. All loads are to be supplied power at a specified voltage within some tolerance, which depends on application. The tolerance of the alternator can be maintained within this range by suitably controlling the excitation of

This paper proposes an application of a hierarchical automatic voltage regulation scheme for wind power plants connected to HV networks. The proposed control schemes is based on a given topology of wind power plants. In particular, we assume that wind generators are connected to each other and have a unique point of contact at the HV level.

Turbogenerator self-tuning automatic voltage regulator
IEEE Transactions on Energy Conversion, 1999Results are presented from new self-tuning controllers for turbogenerators. Simulations and micromachine tests have been successful, with a prototype self-tuning controller being manufactured. This is intended as a direct replacement for a conventional AVR, so a more conventional fixed parameter controller is also considered, serving as a comparison of

On automatic voltage regulator design for synchronous generators
Proceedings of IEEE International Conference on Control and Applications CCA-94, 1994An investigation for a new generation of practical adaptive automatic voltage regulators for synchronous generators is reported. Root locus methods are used to convincingly demonstrate the nature of the AVR problem. The multivariable structure of an existing additional feedback solution is explored.

Fractional-Order Controller for Automatic Voltage Regulator
2018 IEEE Applied Signal Processing Conference (ASPCON), 2018This paper represents fractional-order concept of PID controller and its application on Automatic Voltage Regulator. The aim of the work is to model and control the performance of an AVR with FOPID controller and compare the performance of the first with conventional PID controller.

Automatic Voltage Regulation of DC Shunt Generators
IEEE Transactions on Industrial Electronics and Control Instrumentation, 1973In a dc shunt generator, as the load increases the terminal voltage falls, giving a drooping characteristic. The regulation of voltage involves the adjustment of field excitation. A simple method of voltage regulation by automatic adjustment of field excitation making use of transistor circuitry is discussed.

An Automatically Regulated Precision High Voltage Source
Review of Scientific Instruments, 1934It is frequently desirable to generate very steady high voltage direct current from low voltage alternating current obtained from a source subject to violent fluctuation. An instrument is described which will maintain output voltage constant to less than one percent so long as the supply voltage remains in the range between 95 and 165 volts.
