Abstract
The article considers the issue of reliability of the results of analytical calculation of the feedforward control angle of power electric valves and the commutate angle of a three-phase bridge compensating converter of electric energy with one commutating link. It is noted that the value of these angles determines the capabilities of the converter regarding the generation of reactive energy together with the power supply of the consumer of direct current electric energy. Based on the complexity of the analytical calculation of these characteristics, the issue of verification of the obtained results is relevant, which also confirms the adequacy of the applied research methodology. As a tool for achieving the goal of the work, the authors use circuit simulation in the Micro Cap package. The modeling technique is described in detail, the results of modeling several modes of converter operation are presented, and these results are analyzed. A comparative analysis of the numerical values of the control and commutating angles obtained as a result of analytical calculation and circuit modeling of the same modes of converter operation showed that the discrepancy does not exceed 5%. This indicates the adequacy of the applied modeling technique and the acceptable accuracy of the results of analytical calculations. Refer. 3, fig. 3, table 3.
