en Limba Engleză Hardback – 29 dec 2021

Subliniem în acest volum o structură progresivă riguroasă, care ghidează cititorul de la fundamentele ingineriei electrice până la implementarea practică a soluțiilor de control în rețelele de transport complexe. Autorul KK Sen propune o abordare tehnică aplicată, tratând modelarea dispozitivelor esențiale precum transformatorul de reglare a tensiunii (VRT), regulatorul de unghi de fază (PAR) și controlerul unificat de flux de putere (UPFC). Considerăm că valoarea distinctivă a lucrării rezidă în furnizarea codurilor de simulare EMTP, permițând inginerilor să testeze algoritmii pe modele de rețea reale, nu doar în scenarii teoretice. Ne-a atras atenția capitolul dedicat transformatorului Sen (ST), unde sunt detaliate designurile cu două nuclee și arhitecturile hibride, soluții vitale pentru gestionarea congestiilor în infrastructurile energetice actuale. Complementar titlului Flexible AC Transmission Systems: Modelling and Control de Xiao-Ping Zhang, care se concentrează pe stabilitatea semnalelor mici și controlul tensiunii, volumul de față acoperă zona critică a reglării impedanței și oferă o perspectivă constructivă directă, bazată pe experiența de inventator a autorului. Textul menține un ton pragmatic, coroborând ecuațiile caracteristice ale controlerelor cu date provenite din exploatarea reală a sistemelor. Publicată sub egida IEEE Press Series on Power and Energy Systems de către Wiley, această lucrare de 720 de pagini reprezintă o resursă tehnică densă, esențială pentru înțelegerea modului în care electronica de putere transformă managementul rețelelor inteligente.

De ce să citești această carte

Recomandăm această carte inginerilor de sistem și cercetătorilor care au nevoie de instrumente concrete pentru modelarea fluxului de putere. Câștigul principal este accesul la coduri EMTP gata de utilizat și la studii de caz pe rețele reale. Este un ghid tehnic indispensabil pentru cei care doresc să implementeze tehnologii SMART și transformatoare Sen în infrastructura energetică modernă.

Descriere scurtă

Power Flow Control Solutions for a Modern Grid using SMART Power Flow Controllers Provides students and practicing engineers with the foundation required to perform studies of power system networks and mitigate unique power flow problems
Power Flow Control Solutions for a Modern Grid using SMART Power Flow Controllers is a clear and accessible introduction to power flow control in complex transmission systems. Starting with basic electrical engineering concepts and theory, the authors provide step-by-step explanations of the modeling techniques of various power flow controllers (PFCs), such as the voltage regulating transformer (VRT), the phase angle regulator (PAR), and the unified power flow controller (UPFC). The textbook covers the most up-to-date advancements in the Sen transformer (ST), including various forms of two-core designs and hybrid architectures for a wide variety of applications.
Beginning with an overview of the origin and development of modern power flow controllers, the authors explain each topic in straightforward engineering terms--corroborating theory with relevant mathematics. Throughout the text, easy-to-understand chapters present characteristic equations of various power flow controllers, explain modeling in the Electromagnetic Transients Program (EMTP), compare transformer-based and mechanically-switched PFCs, discuss grid congestion and power flow limitations, and more. This comprehensive textbook:
  • Describes why effective Power Flow Controllers should be viewed as impedance regulators
  • Provides computer simulation codes of the various power flow controllers in the EMTP programming language
  • Contains numerous worked examples and data cases to clarify complex issues
  • Includes results from the simulation study of an actual network
  • Features models based on the real-world experiences the authors, co-inventors of first-generation FACTS controllers
Written by two acknowledged leaders in the field, Power Flow Control Solutions for a Modern Grid using SMART Power Flow Controllers is an ideal textbook for graduate students in electrical engineering, and a must-read for power engineering practitioners, regulators, and researchers.
