“…One way to attempt this goal is to synthesis an electrical ladder network model (ELNM) parameters for a transformer winding COMPEL 43,1 (Mukherjee and Satish, 2012;Reddy et al, 2023;Biswas and Satish, 2019;Ren et al, 2021). As such, several electrical models have been synthesized using analytical calculation method (Biswas and Satish, 2019;Abeywickrama et al, 2006) and finite elements (Abu-Siada et al, 2019;Dawood et al, 2023). However, these stated methods are not always valid because in practical cases, the design details of the transformer windings are usually not available.…”

Purpose Although, numerous optimization algorithms have been devoted to construct an electrical ladder network model (ELNM), they suffer from some frail points such as insufficient accuracy as well as the majority of them are unconstrained, which result in optimal solutions that violate certain security operational constraints. For this purpose, this paper aims to propose a flexible-constraint coyote optimization algorithm; the novelty lies in these points: penalty function is introduced in the objective function to discard any unfeasible solution, an advanced constraint handling technique and empirical relationship between the physical estimated parameters and their natural frequencies. Design/methodology/approach Frequency response analysis (FRA) is very significant for transformer winding diagnosis. Interpreting results of a transformer winding FRA is quite challenging. This paper proposes a new methodology to synthesize a nearly unique ELNM physically and electrically coupled for power transformer winding, basing on K-means and metaheuristic algorithm. To this end, the K-means method is used to cluster the setting of control variables, including the self-mutual inductances/capacitances, and the resistances parameters. Afterward, metaheuristic algorithm is applied to determine the cluster centers with high precision and efficiency. Findings FRA is performed on a power transformer winding model. Basing on the proposed methodology, the prior knowledge in selecting the initial guess and search space is avoided and the global solution is ensured. The performance of the abovementioned methodology is compared using evaluation expressions to verify its feasibility and accuracy. Originality/value The proposed method could be generalized for diagnosis of faults in power transformer winding.

“…Transformadores conversores normalmente são especificados com impedâncias consideravelmente altas, para contribuir com a limitação das correntes de falta do sistema HVDC. Dessa forma, a influência do fluxo de dispersão na composição das perdas em carga do transformador para HVDC é extremamente significativa (DAWOOD, 2023;NI, 2020).…”
