On the Methods of Resonance Identification in Power Systems
There are several methods for resonance identification in power systems each of which has its own advantages and disadvantages. In this paper, three methods for resonance identification are discussed; namely: Impedance Scan (ImS), Harmonic Resonance Modal Analysis (HRMA), and the method based on Determinant of the Transfer Function (DTF).
Going to the mathematical concept behind each method, and giving the physical meaning of these concepts in power systems, the applicability of using these methods in power systems is investigated. In this way, it is concluded that ImS is suitable for graphical representation of the resonances, HRMA is good if more insight about the resonances is needed, while DTF, which has the advantage of representing the behavior of the system with a single number, can have some limitations that need to be taken into account when used in resonance studies.
