Study of electric drive with thyristor voltage regulator

Abstract

In the modern world, the electric drive has tasks of different nature, depending on the application and technological process. At the moment, induction electric drives, which operate by direct start, are widely used. This method has negative factors: high starting currents at the launch; impact loads on the mechanical system. During continuous running mode of the electric motor with direct start, its resource and mechanical system is reduced. Thyristor voltage regulators is used extensively to solve this problem. Ramp generators are used for soft start, the parameters of which determine the settling time and how efficiently the peak currents and torques will be reduced. Object of research: induction electric drive with thyristor voltage regulator. Purpose of research: research of parameters of ramp generator for electric drive with thyristor voltage regulator. Methods of research: numerical methods for solving differential equations, functional diagrams, control system topology, electric drive theory. Main results of research: A generalized algorithm for the control system of thyristor voltage regulator keys is presented. An analysis was made for parameters of ramp generator in the electric drive with thyristor voltage regulator.
