Partial discharge (PD) fault diagnosis is of great importance for ensuring the safe and stable operation power transformers. To address issues low accuracy in traditional PD diagnostic methods, this paper proposes a novel method transformer diagnosis. It incorporates approximate entropy (ApEn) symplectic geometry mode decomposition (SGMD) into optimized bidirectional long short-term memory (BILSTM) neural network. This extracts dominant features employing SGMD ApEn. Meanwhile, it improves...
With the increasing building energy consumption, integrated photovoltaic has emerged. However, this method problems such as low absorption rate and large load peak–valley difference. For reason, authors have constructed a photovoltaic-phase change material system considering demand response. Under response at time of use, was powered by power generation. The thermostatically controlled inside buildings satisfied jointly phase storage air conditioning. can run offline or connected to grid...
Abstract Insulation deterioration, which is mainly caused by partial discharge (PD) occurring inside power transformers, one of the prime reasons to cause transformer faults. Therefore, an effective diagnosis PD crucial ensure safe and stable operation transformers. To extract more features that characterise transformers signals enhance recognition accuracy, a novel fault model based on improved adaptive local iterative filtering (ALIF) bidirectional long short‐term memory (BILSTM) neural...
In recent years, pipeline transportation technology has been rapidly developing in China. A large number of new gas (coal gas) pipelines, sewage and running water pipelines must pass beneath existing roads, railways or buildings. Due to the local conditions restrictions for construction, open cut digging often cannot be used, only trenchless methods may employed. order further reduce effect construction on recently developed grid jacking employed, which minimizes impact structures. This...
