Performance and analysis for improvement of power quality and voltage sag mitigation
Aiming further to reduce its switching losses, an appropriate discontinuous modulation scheme is proposed and studied here in detail to doubly ensure that maxi-mal reduction of commutations is achieved. With an appropriately designed control scheme had incorporated with nine-switch converter is shown to favorably raise the overall power quality and voltage mitigation hence justifying its role a...

در سالهای اخیر،اختلالات کیفیت توان مهمترین موضوع می باشد که محققان زیادی را برای پیدا کردن راه حلی برای حل آن علاقه مند ساخته است.امروزه کیفیت توان در سیستم قدرت برای مراکز صنعتی،تجاری وکاربردهای بیمارستانی مسئله مهمی می باشد.مشکل ولتاژمثل شرایط افت ولتاژواضافه جریان ناشی از اتصال کوتاه مدار یا وقوع خطا در سیستم بیشتر مورد توجه می باشد. برای مطالعه افت ولتاژ واضافه جریان،محققان زیادی کار کرده ...
15 صفحه اولVoltage Sag Mitigation in Eight Bus System Using D-statcom for Power Quality Improvement
This work deals with modeling and simulation of multi bus system using D-STATCOM. Voltage sag is increased by connecting a heavy load. The sag is mitigated using D-STATCOM. The circuit models and simulation results are presented. The Simulation results are compared with the analytical results. KeywordsDistribution Static Synchronous Compensator (D-STATCOM)
متن کاملEnhancement of Power Quality and Voltage Sag Mitigation Using a Novel Nine Switch Power Conditioner
This paper proposes a novel nine switch converter based integrated power conditioner in place of conventional twelve switch converter based power conditioner for improving power quality. Space vector modulation scheme is proposed for producing gating signals for nine switch converter. In the proposed integrated power conditioner the nine-switch converter replaces shunt and series converters fou...
متن کاملA Novel Reduced Switch Power Quality Improvement for Current Harmonic Compensation and Voltage Sag Mitigation Using Model Predictive Control
Power quality is one of major concerns in the present area. It has become important, especially, with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply that results in a failure of end use equipment’s. One of the major problems dealt here is the voltage sag. To solve this problem, custom power devices are used. One of those devices is ...
