Abstract
Abstract. Due to the development of technologies, the widely used electromechanical relays in the electric power industry have been replaced by multifunctional digital relay protection terminals. For the training of students and electrical personnel of enterprises, new approaches to the creation of experimental stands are needed, which will allow us to study the features of the use of digital protection and fully reveal their capabilities. The purpose of the work is to improve the quality of the knowledge and practical skills received by students in working with digital protection blocks. To achieve the goal, a specialized laboratory stand for testing digital security terminals has been developed. The stand consists of a mathematical model of the protected object and hardware, due to which the model mode parameters are converted into physical signals and fed in real time to a real digital device. The study of the protected element is provided in the characteristic modes of its operation close to real ones by providing a connection between the relay protection terminal and the information model. The equipment used at the stand does not require significant capital investments, and therefore this approach is available to most design and training organizations. Keywords: digital protection terminal, experimental stand, analog-to-digital converter; digital-to-analog converter, mathematical model, induction motor.
