This paper provides an optimized (Distributed STATCOM) control for wind electricgenerator. The transient behavior of squirrel cage wind electric generator (SCWEG) can beimproved by injecting large amounts of reactive component during the fault recovery. ThisSystem requires a high dynamic converter, which able to work under abnormal conditions.The reactive power demand, which is necessary for fixed- speed wind turbine system(FSWTS) during faults is not met by capacitor banks installed near (SCWEG). This paperanalyzes the impact of (D- STATCOM) in a grid connected (SCWEG) under fault and offersstudy of the whole performance of the system which can be improved by means ofDistributed Static Synchronous Compensator (D-STATCOM). It is used for restoring thevoltage at generator terminals under fault conditions was occurred. Simulation was carried outby MATLAB SIMULINK under abnormal conditions. Both real and reactive powers confirmthat the (D- STATCOM) has good performance with (SCWEG), and the voltage profile isimproved, the stability is increased and the performance of the complete system is improved. فىِ هذاَ البحثِ تمَ الترکیزُ على تحسین عدم الاستقرار فی الجهد واداء توربیناتِ الریاحِ التى تحتوىِ علىَ المولدِ الحثىٍ ذو القفص السنجابی وذلک فی حاله حدوث خطا وذلک باستخدام المعوض التوزیعی الساکن (D-STATCOM) وتحسین کفائه النظام من خلاله .

This paper presents a comparative modeling and analysis of an induction furnace for melting aluminum (Al) and copper (Cu), focusing on their electromagnetic behavior and heating performance. The study employs ANSYS Maxwell software version 16.0 with the finite element method (FEM) to simulate eddy current generation, Joule heating, and current density distribution in the metallic workpieces. The effects of coil geometry, input current, and operating frequency (50–100 kHz) on heating efficiency and skin depth are investigated. Estimated heating times based on ohmic losses are provided, revealing significant differences between aluminum and copper due to their distinct electrical and thermal properties. The results demonstrate that higher frequencies concentrate heating near the surface, reducing skin depth, while copper exhibits more uniform heating than aluminum. These findings offer practical insights for optimizing induction furnace design and operation for different non-ferrous metals.

This paper analyzes the impact of STATCOM in a grid connected SCWEG under fault and offers study of the whole performance of the system which can be improved by means of (STATCOM). It is used for restoring the voltage at generator terminals under fault conditions was occurred. The performance analysis has been worked out for modified Standard IEEE-14 bus test systems connected to grid with SCWEG to evaluate the voltage stability analysis with STATCOM, the results demonstrate that implementing STATCOM improve the reliability of the grid, good performance, and the voltage profile is improved, simulations was performed in MATLAB/SIMULINK version 2016, and the Power System Analysis Toolbox (PSAT) package Version 2.1.10 are used for the simulation.
