REGENERATIVE ELECTRONIC LOAD FOR UNINTERRUPTIBLE POWER SOURCE TESTING

O. V. Statsenko

Abstract


The article is devoted to the development of active electronic load for testing uninterruptible power sources with the function of recovering energy to the grid. The requirements for uninterruptible power sources testing have been analyzed, the existing approaches to the construction of electronic loads have been reviewed and their drawbacks have been identified. The electronic load structure and approaches for controlling it are proposed. A virtual model of the proposed electronic load is developed in MATLAB Simulink software environment. Using the developed model, studies of the electronic load operation were carried out when testing a sinusoidal voltage source and recovering energy to the power supply grid. For the main modes of operation, the key parameters of the electronic load have been calculated and shown that its use meets the requirements for testing of uninterruptible power sources.
