Approach Method to Evaluate the Total Harmonic Distortion for a System has Multiple Nonlinear Loads
In power quality, harmonics problems are worse than transient events, such as lighting or voltage sags. The harmonics problems could get worse if more than one nonlinear load were connected on a system. Therefore, such distortion should be avoided to protect the power system source and the electrical devises. In this article a new technique was developed to estimate the total harmonic distortion for a system that has multiple nonlinear loads without performing detailed interconnected system analysis. This technique was successfully utilized on Matlab. The technique gives acceptable results.
