Desenvolvimento de algoritmos de medição de harmônicas, flutuação de tensão e valor eficaz segundo normas da família iec 61000

Abstract

The companies that provide services in the solar energy area must constantly seek ways to reduce expenses and make their products more efficient and competitive, always taking into account the legislation. In order to enable advances in the development of photovoltaic inverters and adaptation to operating standards, the use of the Hardware-in-the-loop (HIL) technology has stood out, as it allows the simulation of the hardware of photovoltaic inverters, without the need for physical equipment. Aiming to meet the demand of companies to sell products that meet current standards, the development of certification tests for photovoltaic inverters using HIL emerges as a great proposal. To carry out the certification of a photovoltaic inverter, it is necessary that the measurements of electrical quantities (voltage, current, harmonics, etc.) are made in a standardized way. This work contributes to advance the certification of photovoltaic inverters through the implementation of measurement algorithms according to IEC standards and availability of a measurement algorithm evaluation methodology. The results obtained show that the implemented algorithms are suitable for carrying out pre-certification tests for photovoltaic inverters.
