Lvov I. Two-level System for Electrotechnical Devices Voltage Regulation

The thesis considers the question of voltage regulation of power transformers with under load control devices. There had been developed the law for voltage regulation with quick response on considerable voltage deviation, for power transformers; the law for voltage regulation with adaptive insensitivity zone; the law for two-level voltage regulation. The synthesis method for voltage regulation systems together the algorithms of their functioning had been improved by application of the mathematical apparatus of sequences. There had been carried out the computer simulation of the developed systems' operation and its efficiency had been researched. The optimization methods for parameters of the developed systems for voltage regulation had been further developed. The microprocessor realization of voltage regulation system had been suggested and estimation of measuring channels errors had been done.
