Equivalent wide bandwidth transformer modeling using physics-consistent error compensation model

Le résumé fourni par la source

Wide bandwidth transformer modeling has been a critical part in the power system. However, achieving a balance between modeling accuracy and computational efficiency remains a significant challenge. To address this, the present study introduces a novel physics-consistent error compensation model (PCEC), which integrates a data reconstruction module, an adaptive parameter generation module, and an error compensation module. First, the data reconstruction module effectively denoises the input signals. The processed data are then utilized to generate RLC model parameters, incorporating time-varying physical properties into the PCEC framework. Meanwhile, the same data are re-parameterized and used as input to the error compensation module, which corrects deviations in the RLC model. To ensure the reliability of PCEC, a field experiment is conducted to gather essential voltage data. The effectiveness of the proposed model is validated through three analytical experiments, while the importance of individual modules is further demonstrated through two ablation studies.
