Load Frequency Control in Multi-Area Power Systems is a research work that focuses on the importance and challenges associated with load frequency control (LFC) in power systems with multiple interconnected areas. The work discusses various techniques and control strategies used to maintain frequency stability and balance load demand across multiple areas. The paper explores different control methods employed in LFC, including conventional proportional-integral (PI) controllers, frequency bias-based controllers, and advanced control techniques such as fuzzy logic control, adaptive control,...

This work presents an innovative control approach for Power Factor Correction (PFC) in a three-phase PWM AC chopper. It employs the HBCC technique to drive a three-phase squirrel cage Induction Motor (IM) and supports both soft starting and speed control modes. What sets this strategy apart is its remarkable simplicity, reliability, high efficiency, and cost-effectiveness, achieved by minimizing the number of power semiconductor switches in the power circuitry. The three-phase PWM AC chopper is built using only four IGBTs, and a new closed-loop control methodology is devised, utilizing just...

Ce travail présente une approche de contrôle innovante pour la correction du facteur de puissance (PFC) dans un hacheur triphasé PWM AC. Il utilise la technique HBCC pour piloter un moteur à induction triphasé à cage d'écureuil (IM) et prend en charge les modes de démarrage progressif et de contrôle de la vitesse. Cette stratégie se distingue par sa simplicité, sa fiabilité, son efficacité élevée et sa rentabilité remarquables, obtenues en minimisant le nombre de commutateurs à semi-conducteurs de puissance dans le circuit d'alimentation. Le hacheur triphasé PWM AC est...
