Abstract
This article presents a new method for smoothly starting high-voltage and powerful asynchronous electric drives of pump installations in mining enterprises and thermal power plants. For smooth starting of low- and medium-power asynchronous motors, the "Tyristor Voltage Converter-Asynchronous Motor" system is used. For smooth starting of high-voltage and powerful asynchronous motors, a method for starting using combined low-power thyristors was proposed, taking into account the fact that the prices for high-power thyristors are expensive and unreliable.
