RJR SOFT: A Java-based harmonic content evaluation system using data measurement with Single Tuned Filter and Sine Wave Filter

Most of power electronic software simulates harmonics based only on its build-in electronic components. This paper reports the development of RJR SOFT, software that is specifically designed for evaluating harmonic content. This software is developed in Java programming language and can simulate harmonics based on field data measurement. It can also check the harmonic according to IEEE 519-1992 standard, calculate the filter parameters for Single Tuned Filter and Sine Wave Filter automatically, simulate the effect of the filter on time series harmonic sources, and analyze the harmonic frequencies with built-in DFT analysis tools. The software has been validated using harmonic model in PSIM software and real experimental data. In particular, the simulation and experimental results obtained from RJR SOFT and PSIM show similar trends.
