AC/DC Hybrid Large-Scale Power Grid System Protection

System protection is laid between the defenses for power system protective relaying and the emergency control. Under the premise of ensuring the safety of electrical equipment, it strives to ensure the safety of the system, block the chain of occurrence and growth of cascading faults, and effectively avoid the occurrence of large-scale blackout catastrophes. This book systematically elaborates on the dealing technology of a special type of fault, the “cascading fault”, in the AC-DC hybrid large-scale power grid. The main contents include immunization distance protection for accident overload; distance protection that is immune to oscillation; inverter control technology to prevent long-term or continuous commutation failure; DC participation emergency power flow control technology used to share the accident transfer overload caused by inverter lockout; and overhead transmission line adaptive overload protection.The basis of English translation of this book from its Chinese original manuscript was done with the help of artificial intelligence (machine translation by the service provider DeepL.com). A subsequent human revision of the content was done by the author.

Applied Physiology in Respiratory Mechanics

The close correlations between anatomo-functional data and clinical aspects are substantiated by the study and interpretation of the data of respiratory mechan ics. This field has developed to such an extent that, today, it is hard to single out one researcher who is an expert of the whole sector, whereas super experts can be found among scholars who, thanks to their studies and continuous comparisons, have contributed to the widening of knowledge and the development of that part of research which correlates some basic disciplines with clinical medicine. This notion is of paramount importance. Indeed, it has to be regarded as a starting point requiring a more precise definition. The analysis of data concern ing ventilation parameters is based on the use of mathematical models that are necessary to simplify the complexity of the various clinical situations. For a cor rect application and interpretation of data, the most recent technological acquisi tions in terms of ventilatory support require to be used as a function of simple mathematical models for the study, control and evolution of the lung diseases that concern the ICU. Thus, the need has arisen to compare the experience acquired in the field of applied physiology and in the clinical sector.
