کاهش تلفات و اصلاح شبکه های توزیع با بکارگیری aplc(active power line conditioners)
این پایان نامه در ارتباط با اصلاح کننده های کیفیت توان و یا active power line conditionersکه به اختصار به aplc معروف است ، می باشد aplcیکی از مهمترین سیستمهایی می باشد که می تواند مشکلات مربوط به کیفیت قدرت ر سیستمهای توزیع را حل نماید. aplc به مجموعه ای از اکتیو فیلترها خطاب می شود. در حال حاضر هیچ تعریف منحصر به فردی جهت محاسبه توان برای شکل موجهای کلی ولتاژ وجریان وجود ندارد....
15 صفحه اولFuzzy Logic Controller Based Active Power Line Conditioners for Compensating Reactive Power and Harmonics
This article explores a novel fuzzy logic controller (FLC) based threephase shunt active power line conditioners (APLC) for power quality improvements due to the non-linear loads. The fuzzy logic controller is Mamdani-type and linguistic description, so it does not necessitate a mathematical model of the system. The FLC controller is capable of controlling harmonic current and dc-side capacitor...
متن کاملImproving Compensation Performance in Three- Phase Active Power Line Conditioners by DC-Voltage Control
This paper analyses the influence of the prescribed DC-link voltage on the filtering efficiency, in terms of current harmonic distortion after compensation, in a three-phase three-wire shunt active power line conditioner. The AC voltage controller as nonlinear load and two configurations of the coupling filter are taken into consideration. It is pointed out that, for each rms current to be comp...
متن کاملActive Power Conditioners to Mitigate Power Quality Problems in Industrial Facilities
Non-linear loads are commonly present in industrial facilities, service facilities, office build‐ ings, and even in our homes. They are the source of several Power Quality problems such as harmonics, reactive power, flicker and resonance [1-3]. Therefore, it can be observed an in‐ creasing deterioration of the electrical power grid voltage and current waveforms, mainly due to the contamination ...
متن کاملHarmonic Mitigation Using Unified Power Quality Conditioners and Hybrid Active Power Filters
The power quality issues are of great concern now a days. The increasing use of power electronic devices based nonlinear loads deteriorate the quality of power. Power electronic appliances are widely used in industrial, commercial and utility system thus leading to various power quality problems. This leads to harmonics being injected into the distribution system and also reactive power burden....
