To address DC‐side voltage imbalance in star‐connected cascaded H‐bridge STATCOMs under unbalanced grids, a hybrid‐frequency power loop is introduced to enable interphase power transfer. A hybrid‐frequency PWM (HFPWM) method based on voltage vector superposition is proposed, which maintains superior output characteristics for the intermediate‐frequency

Permanent Fault Identification Scheme for Distribution Feeders Using Detection‐Based Reclosing
This paper proposes a novel permanent fault identification scheme based on detection‐based reclosing to mitigate the risks of blind three‐phase reclosing and overcome the sensitivity limitations of existing methods. ABSTRACT To mitigate secondary damage caused by reclosing a distribution line with a permanent fault, a highly sensitive fault property ...
