Software para automatização de ensaios de inversores fotovoltaicos em acordo com a NBR 16150:2013

Abstract

Tests for assessing the conformity of photovoltaic inverters to the current regulations are of great importance to guarantee compatibility and quality of the electric network energy to which they are connected. In Brazil, the main standard for inverter compliance testing is ABNT NBR 16150 based on the performance requirements of ABNT NBR 16149. This work presents the development of software routines capable of controlling the necessary equip- ment for the tests, performing the data acquisition and generating the test report. For that, Labview®graphical programming environment was used, as it is an appropriate programming language for the application, has a set of pre-developed graphical interface functions and a set of libraries for communicating with equipments. Comparative experimental results between automated tests with developed software routines and non-automated methods were performed to validate the technique. As a result, a test method is obtained with less dependence on the operator, resulting in reduced errors and less performance time.
