A stand for the study of the operability and quality of functioning of electrical complexes and electric drive systems with frequency regulators

THE PURPOSE. To develop a stand for the study of the operability and quality of functioning of electrical complexes and electric drive systems with frequency regulators that have undergone major repairs.

METHODS. When solving this problem, the method of direct evaluation of the mechanical characteristics of the system Source-Frequency ConverterMotor-Load was used, methods of direct evaluation of input parameters with subsequent calculation of indicators, methods of increasing algorithmic redundancy, mathematical methods of checks, logical control methods and complex control methods (the method of control tests, the method of control programs) were used. RESULTS. The analysis of test methods of frequency regulators was carried out, the necessary equipment was selected, stand control algorithms were determined, design documentation was developed, a stand was made to study the operability and quality of functioning of electrical complexes and electric drive systems with frequency regulators, the software of its control system was debugged, frequency converters were tested according to the developed methodology in accordance with GOST requirements.

CONCLUSION. One of the most effective ways to determine the state of the frequency controller before sending it for installation is to check on a test bench to determine the degree of operability of the control and protection system, as well as the power part. The developed stand makes it possible to solve a wide range of tasks for the study of the operability and quality of functioning of electrical complexes and electric drive systems with frequency regulators that have undergone major repairs.
