Keywords:

Abstract
Impact-excited turbine generators are installed in high-power laboratories of test centers for testing various electrical equipment and ensuring the necessary short-circuit power. Tests of high-capacity electrical power equipment require an increase in the short-circuit power of existing impact-excited turbine generators. The article discusses the experience gained from designing and manufacturing impact-excited generators. The main ways of increasing the capacity of impact-excited generators and related limitations are described. A method and criteria for optimizing the parameters of impact-excited turbine generators and their basic dimensions to ensure certain operation modes in which electrical equipment is tested at test centers are given. The ways of reducing the subtransient reactance, which determines the peak short-circuit current and peak short-circuit power of impact-excited generators, are considered.
