Experimental studies on the performance of C.I engine with TME blends
ISBN: 9783846507575 / Angielski / Miękka / 2012 / 124 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Bio-diesel manufactured from vegetable oils, animal fats and used cooking oils is an alternative fuel for diesel engines. It offers many advantages such as renewable, energy efficient, nontoxic, sulfur free and bio-degradable, and also offers cleaner combustion and reduces global warming gas emissions. The present work reports on the preparation of bio-diesel (methyl esters) from selected edible and non edible oils and their performance and emission characteristics. The experiments are carried out in three stages on a Single cylinder kirlosker diesel engine which is commonly used in...

FAULT CURRENT REDUCTION TECHNIQUE IN A DISTRIBUTION SYSTEMS
ISBN: 9786206157618 / Angielski / Miękka / 76 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. In this book, the application of the active SFCL into in a power distribution network with DG units is investigated. For the power frequency overvoltage caused by a single-phase grounded fault, the active SFCL can help to reduce the over- voltage's amplitude and avoid damaging the relevant distribution equipment. The active SFCL can as well suppress the short-circuit current induced by a three-phase grounded fault effectively, and the power system's safety and reliability can be improved. Moreover, along with the decrease of the distance between the fault location and the SFCL's installation...

Root Caries and Management
ISBN: 9786206160762 / Angielski / Miękka / 168 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Dental caries is an ancient disease that has been found in skulls from all over the world where the primitive man lived in isolated areas and the diet lacked refined and carbohydrate-rich food. Root caries is a lesion located on the root surface of a tooth, usually close to or below the gingival margin, and is the major cause of tooth loss in older adults, and tooth loss is the most significant oral health-related negative variable of quality of life for the elderly population who get their teeth extracted and replaced with removable prostheses. At present, root caries is becoming a new area...

OPTIMAL DG PLACEMENT FOR VOLTAGE IMPROVEMENT USING PSO
ISBN: 9786205522585 / Angielski / Miękka / 80 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The size and location of DG are the crucial factors in the application of DG for loss minimization. This book presents an algorithm for the identification of bus location using Sensitivity analysis and also an algorithm for the determination of size of the DG using PSO. This methodology is tested on IEEE 15 bus system. By installing DGs at all the potential locations with the determined sizes, the total real power loss of the system has been reduced by 83% and the voltage profile of the system is also improved. The harmonics that are present in the system are reduced by placing capacitors at...

A Sliding Mode Approach To Enhance The Power Quality
ISBN: 9786206152125 / Angielski / Miękka / 52 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. An integral terminal sliding mode control design was proposed to enhance the power quality of wind turbines under unbalanced voltage conditions. The design combines the robustness, fast response, and high quality transient characteristics of the integral terminal sliding mode control with the estimation properties of disturbance observers. It was successfully implemented to both the rotor-side (RSC) and grid side (GSC) converters of a DFIG-based wind turbine. The controller gains were auto tuned using a fuzzy logic approach. Its performance was assessed in the presence of deep voltage sags...

POWER QUALITY ENHANCEMENT
ISBN: 9786205522745 / Angielski / Miękka / 64 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This book presents the nine switch converter based UPQC is simulated using MAT LAB/SIMULINK. It effectively reduces the current and voltage harmonics. The nine-switch converter is more suitable for replacing back- to-back converter in "series-shunt" systems. As a further performance booster, a modified space vector modulation and 120 degree modulation scheme is presented for reducing the overall commutation count by 33%. It is also compensated for voltage sags, total harmonic distortion with proper series and shunt controls. Since the number of switches required is less compared to...
