Optimizing intensive automatic voltage regulator parameters
2009 5th International Symposium on Applied Computational Intelligence and Informatics, 2009The present paper focuses on the use of intensive automatic voltage regulators (AVRs) to improve the dynamic behaviour of high power synchronous generators (SGs) considering the influence of the entire power system (PS). The case study discusses the SGs within two significant power plants in Romania (Turceni and Rovinari).

Automatic voltage regulator using an AC voltage-voltage converter
IEEE Transactions on Industry Applications, 2000Voltage sags and extended undervoltages are one of the main concerns of industry today. These voltage sags could cause high negative impact on productivity, which is certainly an undesirable aspect in industrial and commercial applications. Current tap-changing transformers used in distribution systems have proven to be inadequate in solving these ...

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 ...

Automatic voltage regulator with fastdynamic speed
IEE Proceedings - Electric Power Applications, 1999A novel automatic voltage regulator is proposed and analysed. The power circuit is made up of a pulse-width modulated (PWM) buck-boost AC chopper which uses only two standard switch modules. In the AC chopper, the commutation scheme allows dead-time to avoid current spikes from switching and at the same time establishes a current path in the inductor ...

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

Comments on "Three-Arm AC Automatic Voltage Regulator
IEEE Transactions on Industrial Electronics, 2012Some errors in the three-arm automatic voltage regulator in the paper “Three-Arm AC Automatic Voltage Regulator” by Wu (IEEE Trans. Ind. Electron, vol. 58, no. 2, pp. 567-575, Feb. 2011) are pointed out, and a technique for correcting these errors is given.

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
