A Novel Harmonic Resonance Quantification Evaluation Index Based on Measured Data

Harmonic resonance is an intrinsic characteristic of the power system and can pose a risk to the security of the system when it becomes severe. It is important to note that not all harmonic resonances have a significant impact on the system's safety and stability. It is now necessary to enhance the practicality of the widely used harmonic resonance detection approach since it depends too much on the system model. It is necessary to develop a quantitative harmonic resonance index based on observed data. By examining the expression of the harmonic impedance of a power system and exploring the influencing elements of resonance amplification, this research provides a quantitative assessment index of harmonic resonance amplification. This index has the ability to analyze harmonic resonance and perform quantitative evaluation.
